제동 안전선 구축 : 에어 브레이크 시스템의 구성 및 유지 관리 세부 사항

트럭 에어 브레이크 시스템의 주요 구성 요소는 무엇입니까?

는 트럭 에어 브레이크 시스템 대형차량의 안전운행을 위한 중요한 보증입니다. 효율적이고 안정적인 제동 효과를 얻기 위해 압축 공기를 사용하여 브레이크 장치를 구동합니다. 시스템은 복잡한 구조를 가지고 있으며 다양한 전문적인 구성요소로 구성되어 있습니다. 다양한 부품이 서로 협력하여 차량이 다양한 작업 조건에서 안정적으로 제동할 수 있도록 합니다.
공기 압축기
는 air compressor is the power source of the entire air brake system. Its main function is to use the engine power to compress the air, compress the air in the atmosphere to a high pressure state, and provide the system with the air source required for braking. The air compressor is usually driven by the engine crankshaft belt, with a sturdy structure and high working efficiency. The compressed air has a high pressure and temperature and needs to be processed later before it can be used.
에어 드라이어
는 air dryer is installed between the air compressor and the air tank. Its main function is to remove moisture and oil from the compressed air to prevent ice and corrosion inside the system. If the moisture in the air is not removed in time, it will cause the brake line to freeze in cold weather, seriously affecting the braking performance. The air dryer contains a desiccant inside, which can effectively absorb moisture, and is equipped with an automatic drainage device to keep the air dry and clean.
에어탱크
는 air tank is used to store compressed air that has been dried to ensure that the brake system has a stable and continuous air supply when in use. The air tank is usually divided into a main air tank and an auxiliary air tank, and the capacity is determined according to the size of the vehicle and the braking demand. Condensation often accumulates inside the air tank and needs to be discharged regularly to prevent internal corrosion and blockage of the pipeline.
브레이크 밸브(풋 브레이크 밸브)
는 brake valve is a key component for the driver to control air brakes. When the brake pedal is pressed, the brake valve adjusts the air pressure to the brake chamber, drives the brake mechanism to operate, and achieves vehicle deceleration or parking. The brake valve used in modern trucks usually integrates pressure feedback and multi-stage adjustment functions to ensure sensitive braking response and safety and reliability.
브레이크 에어 챔버
는 brake air chamber is the core component that converts air pressure into mechanical force. A diaphragm or piston is arranged in the air chamber, which pushes the connecting rod after receiving the air pressure from the brake valve, and drives the brake shoe or brake pad to press the brake drum or brake disc. Brake chambers are divided into service brake chambers and spring brake chambers. The service brake chamber is mainly responsible for braking when the vehicle is driving, while the spring brake chamber is used for parking and emergency braking.
스프링 브레이크 챔버
는 spring brake chamber is equipped with a strong preload spring, which uses the mechanical force of the spring to maintain the braking state. This component is mostly used for parking brakes to ensure that the vehicle does not slip when parking. After the engine is started and inflated, the air pressure will compress the spring and release the braking state. The safety performance of the spring brake chamber is extremely important, and the integrity and air pressure of the spring need to be checked regularly.
브레이크 커넥팅 로드 및 레귤레이터
는 brake connecting rod transmits the thrust of the brake chamber to the brake mechanism to complete the conversion of air pressure to mechanical force. The regulator is responsible for automatically or manually adjusting the gap between the brake shoe and the brake drum to compensate for the wear of the brake shoe and maintain the braking efficiency. The automatic regulator can reduce the frequency of manual adjustment and improve the stability and safety of the system.
브레이크 라인
는 brake line includes the air pipeline connecting the compressor, air tank, brake valve and air chamber. The pipeline material must be resistant to high pressure, corrosion and cold, and is usually made of a combination of rubber hoses and steel hard pipes. Reasonable pipeline design can prevent air pressure leakage and mechanical damage, and is the basis for ensuring the air tightness and stability of the brake system.
안전 밸브
는 safety valve is installed at the air tank and key pipeline positions to prevent the system air pressure from exceeding the set upper limit. When the system air pressure rises abnormally, the safety valve automatically opens to release excess gas to avoid bursting of the air tank or pipeline and ensure system safety. The safety valve must be inspected regularly to ensure its reliability.
보조 장치
는 air brake system is equipped with a variety of auxiliary devices, such as barometers, air pressure alarms and pressure sensors. The barometer provides the driver with real-time air pressure information, and the air pressure alarm sounds an alarm when the air pressure is lower than the safety threshold, reminding the driver to deal with it in time. The pressure sensor provides data support for the vehicle's electronic control unit to ensure intelligent management of the system.

브레이크 챔버는 어떻게 공기압을 기계적 힘으로 변환합니까?

는 brake chamber is a key actuator in the truck air brake system. Its core function is to convert the air pressure energy of compressed air into mechanical force, thereby driving the brake mechanism to slow down or stop the vehicle. The design structure and working principle of the brake chamber are directly related to the response speed of the brake system and the stability of the braking force.
브레이크 챔버의 기본 구조
는 brake chamber is mainly composed of a chamber shell, a diaphragm (or piston), a push rod and a spring. The chamber shell is made of solid metal material, and the interior is divided into two main spaces: the air pressure chamber and the spring chamber. The diaphragm is usually made of wear-resistant rubber material, with good sealing performance and can withstand repeated changes in air pressure. The push rod connects the diaphragm or piston to transmit the thrust generated by the air pressure to the brake mechanical part.
공기압실과 스프링실의 기능적 구분
는 air pressure chamber is the part of the brake chamber that receives compressed air. Air enters the air pressure chamber from the brake valve through the pipeline, and the air pressure increases, pushing the diaphragm or piston outward. The spring chamber is equipped with a preloaded spring to provide reverse force and is used for parking brakes. When the air pressure is low, the spring force pushes the push rod back to the initial position and releases the brake state.
공기압을 기계적 힘으로 변환하는 작동 원리
운전자가 브레이크 페달을 밟으면 브레이크 밸브는 브레이크 에어 챔버의 공기압 챔버로 압축 공기를 유입시킵니다. 기압실 내의 기압이 급격히 상승하여 다이어프램 표면에 작용하여 추력을 발생시킵니다. 추력의 크기는 공기압과 다이어프램의 면적에 비례합니다. 다이어프램은 공기 압력의 작용으로 바깥쪽으로 팽창하여 연결된 푸시 로드를 밀어 축 방향으로 움직입니다. 푸시 로드의 움직임은 커넥팅 로드와 조정 메커니즘을 구동하여 공기압 에너지를 기계적 힘으로 변환하고, 이는 브레이크 슈나 브레이크 패드에 ​​적용되어 브레이크 드럼이나 브레이크 디스크를 고정합니다.
푸시로드 움직임의 기계적 전달
는 end of the push rod is usually connected to the brake connecting rod through a pin or a ball head. The axial movement of the push rod drives the brake mechanism to work. The brake connecting rod converts the linear motion of the push rod into the clamping motion of the brake shoe, forming friction and generating braking force. The distance the push rod moves determines the magnitude of the braking force, and a reasonable push rod stroke design ensures the linearity and sensitivity of the braking effect.
는 difference between diaphragm and piston and their influence
는 diaphragm structure in the brake chamber uses a flexible diaphragm to transmit air pressure thrust. It has a simple structure and light weight, and is suitable for light and medium trucks. The piston chamber uses a rigid piston instead of a diaphragm, which has better sealing and is suitable for heavy vehicles. The piston structure reacts faster to changes in air pressure, and the mechanical force transmission is more stable, which improves braking performance and reliability.
스프링 브레이크 챔버의 특수 기능
는 spring brake chamber is equipped with a large preload spring outside the air pressure chamber, which is often used for parking brakes. During normal operation, the air pressure compresses the spring, the push rod is in a loose state, and the brake is released. When parking or emergency braking, the system air pressure is cut off, the spring releases energy to push the push rod, and the mechanical force acts on the brake mechanism to lock the wheel and achieve parking brake. The spring brake chamber ensures that the vehicle can remain in a safe parking state even if the air source is interrupted.
브레이크실의 기밀성과 응답속도
는 air tightness inside the chamber directly affects the effective conversion and response speed of air pressure energy. Poor sealing will cause air pressure leakage, weaken the push rod pushing force, and increase the risk of brake failure. High-quality diaphragm materials and sealing design ensure that the brake chamber maintains good performance under extreme working conditions. The rapid air pressure charging and discharging process ensures rapid braking response and improves driving safety.
브레이크 챔버의 유지 관리 및 결함 징후
브레이크 챔버 다이어프램 파열, 푸시 로드 걸림 또는 스프링 피로와 같은 일반적인 결함은 브레이크 고장 또는 주차 브레이크 고장으로 이어질 수 있습니다. 공기실의 기밀성을 정기적으로 점검하고 푸시로드 스트로크와 스프링 상태를 감지하는 것은 브레이크 시스템의 신뢰성을 보장하는 열쇠입니다. 공기압 테스트 및 누출 감지를 통해 숨겨진 위험을 사전에 감지하고 운전 사고를 예방할 수 있습니다.

에어 드라이어가 에어 브레이크 시스템에 중요한 이유

에어 드라이어s are an indispensable key component in truck air brake systems. Its main function is to remove moisture and impurities from compressed air to ensure the normal operation and long-term durability of the internal pipes and components of the brake system. The role of air dryers is directly related to the reliability, safety and maintenance cost of the brake system.
압축 공기의 수분과 그 위험
는 air brake system relies on an engine-driven air compressor to supply high-pressure air. After the air is compressed, the temperature rises, and the water vapor in the air begins to condense into water droplets during the cooling process. If these moisture are not effectively treated, they will enter the air tank and pipeline with the air, causing a variety of serious problems. Condensed water accumulates inside the pipeline and may freeze in a low temperature environment, blocking the air path and causing brake failure. Moisture can also cause rust and corrosion of internal parts of the system, reduce equipment life and cause leaks. Excessive moisture can also affect air pressure stability and cause insensitive brake response.
공기 건조기의 작동 원리
에어 드라이어s are usually installed between the air compressor and the air tank. Its core part is a desiccant (such as silica gel or molecular sieve), which can efficiently absorb moisture from the air. When compressed air enters the dryer, moisture is absorbed by the adsorbent, and the air discharged after treatment remains dry and clean. Modern air dryers are mostly equipped with automatic drain valves to regularly discharge moisture and impurities accumulated in the adsorbent to prevent water accumulation and blockage, ensuring a long-lasting and stable drying effect.
브레이크 시스템의 결빙 방지
저온 환경에서는 공기 파이프라인의 습기가 쉽게 얼기 때문에 브레이크 밸브와 공기 챔버가 막혀 브레이크 고장이 발생하거나 차량 제어력이 상실될 수도 있습니다. 공기 건조기는 효과적으로 습기를 제거하고 응축수 축적을 방지하여 얼음 막힘 위험을 크게 줄입니다. 특히 추운 지역이나 겨울철에 운행하는 차량의 경우 차량 제동의 안전성과 안정성을 직접적으로 보장하는 에어 드라이어의 중요성이 특히 두드러집니다.
제동 시스템의 주요 구성 요소를 보호합니다.
는 internal pipes, valves, air chambers and air tanks of the braking system are all precision machinery and sealing components, which are extremely susceptible to moisture erosion. Long-term water vapor intrusion can cause metal rust, aging of sealing rings, and valve jamming, affecting braking performance. Air dryers extend the service life of these key components by providing dry air, reduce failure rates and maintenance costs, and improve the overall operating efficiency of vehicles.
시스템 공기압 안정성 및 응답 속도 향상
과도한 습기는 공기압 변동 및 누출을 유발하여 브레이크 시스템의 기밀성과 공기압 안정성에 영향을 미칠 수 있습니다. 에어 드라이어는 공기 탱크와 파이프라인으로 들어가는 공기가 건조하고 순수하도록 보장하고 안정적인 공기압 공급을 보장합니다. 안정된 공기압은 브레이크실의 효율적인 작용을 지원하고, 제동 응답속도와 제동력을 향상시켜 주행 안전성을 향상시킵니다.
유지보수 난이도 및 비용 절감
에어 드라이어가 없거나 건조 효과가 좋지 않은 시스템은 빈번한 배수, 파이프 청소, 부식 및 손상된 부품 교체가 필요하므로 유지 관리 빈도와 비용이 증가합니다. 공기 건조기는 자동으로 물을 제습하고 배수하여 수동 개입과 ​​유지 관리 작업량을 줄여줍니다. 시스템 고장률이 감소하고 차량 운행 시간이 증가하며 운영 비용이 크게 절감됩니다.
에어 드라이어의 종류 및 적용 시나리오
일반적인 공기 건조기에는 흡착식 건조기와 냉동식 건조기가 포함됩니다. 흡착식 건조기는 건조제를 통해 수분을 흡수하고 구조가 간단하며 트럭 에어 브레이크 시스템에 널리 사용됩니다. 냉동식 건조기는 공기 온도를 낮춤으로써 습기를 응축 및 배출하므로 특별한 환경 요구 사항에 적합합니다. 다양한 유형의 건조기를 차량 작동 환경 및 작업 조건과 결합하여 적절한 모델을 선택하여 최상의 건조 효과를 보장합니다.
에어드라이어 유지관리의 포인트
건조제의 포화불량을 방지하기 위해 정기적으로 건조제를 교체해 주어야 합니다. 응축수와 불순물을 적시에 제거하려면 배수 밸브 기능을 정상적으로 유지해야합니다. 공기 건조기 하우징과 인터페이스의 누출 여부와 밀봉 성능이 양호한지 점검해야 합니다. 부적절한 유지 관리로 인해 건조기 고장이 발생하고 이는 전체 브레이크 시스템의 안전 성능에 영향을 미칩니다.

브레이크 밸브(풋 밸브)는 브레이크 공기압을 어떻게 조절하나요?

는 brake valve, also known as the foot brake valve, is a key component in the truck air brake system where the driver directly controls the brake air pressure. Its main function is to accurately adjust the air pressure according to the force and stroke of the driver's foot on the brake pedal, and drive the brake chamber to achieve vehicle braking. The design and working principle of the brake valve directly affect the response speed, stability and safety performance of the brake system.
브레이크 밸브의 기본 구조
는 brake valve is mainly composed of a valve body, a piston or a sliding valve, a spring, a sealing ring and an adjustment mechanism. There are multiple air passages inside the valve body, which are responsible for guiding the air flow. The piston or sliding valve moves under the action of the spring force and air pressure to control the air flow interruption. The brake pedal drives the piston to move through a mechanical connecting rod or an electronic sensor to complete the air pressure regulation.
브레이크 밸브의 작동 원리
운전자가 브레이크 페달을 밟으면 브레이크 밸브 내부의 피스톤이 페달 스트로크와 함께 전진합니다. 피스톤의 움직임에 따라 밸브 본체 내부의 공기 회로의 개폐 상태가 바뀌고, 공기 탱크에서 브레이크 챔버의 공기압실로의 공기를 제어합니다. 페달을 깊게 밟을수록 밸브가 더 크게 열리고 브레이크 챔버로 유입되는 공기압이 높아집니다. 증가된 공기압은 브레이크 챔버 다이어프램이나 피스톤을 밀어서 제동을 달성하기 위한 기계적 추력을 생성합니다. 페달에서 발을 떼면 피스톤이 재설정되고 공기 회로가 닫히고 공기 압력이 해제되고 브레이크가 해제됩니다.
브레이크 공기압 조절의 정밀 제어
는 brake valve achieves continuous variable adjustment of air pressure through an internal adjustment mechanism. The valve body is designed with a pressure adjustment spring and a feedback device, which can finely adjust the output air pressure according to the pedal force. Accurate air pressure control ensures a smooth transition of braking force, avoids braking shock and vehicle shaking, and improves driving comfort and safety.
다방향 공기회로 설계 및 안전보장
는 brake valve is equipped with multiple air circuits, which lead to different air tanks and air chambers to ensure stable air pressure supply. Some brake valves are equipped with a dual-circuit design, one circuit controls the front axle air chamber and the other controls the rear axle air chamber to improve braking safety. Some advanced brake valves also have an air pressure protection function. When the system air pressure is lower than the set value, the braking force is automatically limited to prevent brake failure.
브레이크 밸브의 응답속도 및 밀봉 성능
는 internal sealing ring and air circuit design of the brake valve directly affect the response speed of air pressure changes. Efficient sealing prevents air leakage and ensures stable air pressure. The brake valve with a compact structure and reasonable spring force can quickly respond to the driver's braking command, achieve rapid braking response, and enhance driving safety.
풋 브레이크 밸브와 주차 브레이크 시스템의 조화
는 foot brake valve is mainly responsible for service braking during driving. The brake valve of some models integrates the parking brake function or is linked with the parking brake valve. The spring brake chamber is controlled by air pressure changes to realize the opening and release of the parking brake. The system design ensures that the parking brake and foot brake work together to meet different driving needs.
브레이크 밸브의 유지 관리 및 고장 증상
브레이크 밸브 씰의 노화, 피스톤 걸림 또는 스프링 고장은 고장의 일반적인 원인입니다. 이로 인해 둔감한 공기압 조절, 공기 누출 또는 고르지 못한 제동이 발생합니다. 브레이크 밸브의 기밀성, 페달 이동 거리, 내부 부품 상태를 정기적으로 점검하여 정상적인 성능을 보장하십시오. 결함이 발견되면 안전 위험을 피하기 위해 적시에 수리하거나 교체해야 합니다.

에어 브레이크 시스템에서 안전 밸브는 어떤 역할을 합니까?

는 safety valve is a vital protective component in the air brake system. It is responsible for releasing excess air pressure when the system pressure rises abnormally, preventing system components from being damaged by overpressure, and ensuring the safety and stable operation of the entire brake system. Although the safety valve does not directly participate in the braking action, it plays an important role in the operation of the system.
는 basic structure and principle of the safety valve
는 safety valve is usually composed of a valve body, a valve seat, a spring, a valve core and an adjustment mechanism. The valve core seals the valve seat under the action of the spring force to maintain the closed state of the system. The spring preload sets the maximum safe air pressure of the system. When the system air pressure exceeds the set value, the air pressure overcomes the spring force to push the valve core open, and the overpressure gas is released through the exhaust port. After the air pressure drops to a safe range, the spring resets the valve core, reseals the valve seat, and the system returns to normal working state.
시스템 과압을 방지하기 위해 공기압의 상한을 제어합니다.
는 air brake system is supplied with air by an air compressor. If the control system fails or the compressor continues to work without stopping, the air pressure may continue to rise. Overpressure can damage and even burst components such as air reservoirs, brake valves, pipelines, and air chambers. The safety valve opens the exhaust in time before the air pressure reaches a dangerous level through the set opening pressure (usually 10%~15% of the upper limit of the system working pressure), playing the role of "the last line of defense" to avoid system damage and accidents.
공기 압축기 및 공기 회로 구성 요소를 보호하십시오.
는 air compressor is a high-frequency component in the brake system, and it is very easy to be damaged due to excessive back pressure during long-term operation. The safety valve releases excess air pressure in the system compression chamber or the main air tank, effectively reducing the compressor load and preventing problems such as shaft seal damage and cylinder jamming caused by back pressure. At the same time, the safety valve also protects the pipeline interface and air circuit valve to avoid impact rupture caused by sudden pressure changes and extend the service life of the system.
차량 제동 시스템의 안정적인 기능 보장
는 air brake system must operate in a stable air pressure environment. Excessive air pressure not only damages the components, but also causes excessive braking response and excessive braking force, causing tire locking and vehicle loss of control. The safety valve limits the peak pressure and keeps the system pressure within a safe range, ensuring that the braking response is linear and controllable, and enhancing the driver's sense of safety and predictability.
는 rationality of the set pressure value and the system match
는 opening pressure of the safety valve should be higher than the normal working pressure of the brake system (usually 0.81.0 MPa), but lower than the maximum pressure bearing capacity of the system. It is generally set to 1.11.2 MPa. If the pressure is set too low, it is easy to open frequently and cause unstable air pressure; if it is set too high, it loses its protective effect. Reasonable setting requires comprehensive consideration of factors such as vehicle air path volume, braking frequency, and compressor air output to ensure that the safety valve intervenes only under real overpressure conditions, taking into account safety and system efficiency.
안전밸브의 설치위치 및 작용범위
는 safety valve is usually installed on the main air tank or the main line of the total air path, giving priority to releasing the total pressure of the system. Some systems are also equipped with local safety valves on branch air tanks or independent air paths to protect branch circuit components. The installation location should ensure smooth exhaust and stay away from high temperature or flammable areas to prevent secondary risks caused by exhaust. The multi-level protection design enhances the robustness of the system and improves the safety level of the vehicle.
안전밸브의 재질 및 내구성 요구사항
안전 밸브s are subjected to high-pressure gas for a long time, and key components such as valve cores, springs, and valve seats must have high strength, corrosion resistance, and fatigue resistance. Common materials include stainless steel, chromium-molybdenum alloy, engineering plastics, etc. The sealing part must have high temperature resistance and pressure change resistance to ensure that the valve remains sealed reliably during high-frequency opening and closing to avoid air pressure leakage or malfunction.
안전밸브의 유지보수 점검 및 고장위험
안전 밸브s are passive action devices. Long-term non-operation is prone to problems such as spring fatigue, valve core jamming, and seal aging. Regular opening and closing tests, cleaning of carbon deposits and foreign matter, and testing of opening pressure are necessary means to maintain its functional reliability. A failed safety valve may not be able to open when overpressure occurs, resulting in system damage or accidents; it may also open prematurely, affecting the inflation speed and efficiency of the brake system.
안전 밸브와 압력 조절 시스템의 협력
에어 브레이크 시스템에는 일반적으로 함께 작동하는 압력 조절기, 압력 스위치 및 안전 밸브가 장착되어 있습니다. 압력 조절기는 압축기의 시작과 정지를 제어하고, 압력 스위치는 공기 압력 피드백을 모니터링하며, 안전 밸브는 다중 안전 메커니즘이 효과적인지 확인하기 위한 중복 보호 장치로 사용됩니다. 안전 밸브의 설계 및 조정은 잘못된 트리거링 또는 기능 중복을 방지하고 시스템의 전반적인 안전성을 향상시키기 위해 전체 공기압 제어 시스템과 조정되어야 합니다.

에어 브레이크 시스템의 일일 유지 관리 우선 순위는 무엇입니까?

에어브레이크 시스템은 대형차량(트럭, 버스, 트레일러 등)의 중요한 안전장치로서, 에어브레이크 시스템의 작동 안정성은 차량 전체의 제동 효과 및 교통안전과 직결됩니다. 시스템은 공기 압축기, 공기 저장소, 건조기, 브레이크 밸브, 브레이크 공기 챔버, 공기 파이프 및 다양한 제어 구성 요소로 구성됩니다. 구조가 복잡하고 자주 작동합니다. 과학적이고 표준화된 일일 유지관리는 시스템의 수명을 연장할 뿐만 아니라 갑작스러운 브레이크 고장을 효과적으로 예방할 수 있습니다.
시스템의 기밀성을 확인하십시오.
는 air tightness of the system is the core of ensuring stable air pressure. During maintenance, it is important to check whether there is air leakage at various pipe joints, hoses, connectors, welds of air reservoirs, and valve body interfaces. Use soapy water smearing method or a special leak detector to detect subtle leaks. For rubber hoses, check whether they are aging, cracked, or falling off. Good air tightness can prevent the system air pressure from dropping too quickly, ensuring the reliability of emergency braking and parking brakes.
정기적으로 공기 탱크의 물과 불순물을 배출하십시오.
는 air tank is a gathering place for compressed air and is also the main area for condensed water and impurities to deposit. If it is not discharged in time, the water will corrode the cylinder, block the valve, and seriously affect the braking response. The air tank drain valve should be opened every day after parking to drain manually, especially in an environment with high humidity or low temperature. Some vehicles are equipped with automatic drainage devices, and their drainage function should also be checked regularly to prevent water accumulation.
에어드라이어의 작동상태를 확인하세요.
는 air dryer is the first line of defense to prevent moisture from entering the brake system. It is necessary to regularly check whether the dryer filter element or adsorbent is saturated and ineffective. If it is found that the drying effect has deteriorated or a large amount of water is discharged from the air tank, the dryer filter element should be replaced in time. Note that the dryer exhaust port should be unobstructed and the exhaust valve should be sensitive to prevent water accumulation or freezing.
브레이크 밸브의 반응성을 유지하십시오.
는 brake valve is the most directly related component of the air brake system to the driver's control. The brake valve pedal stroke should be checked regularly to see if it is appropriate, if the action is smooth, and if there is any jamming, air leakage or poor return. Check if the air chambers respond consistently during braking to avoid brake deflection or tail swinging due to asynchronous braking of the front and rear wheels. Disassemble and clean or replace seals if necessary.
브레이크실 및 푸시로드 상태를 확인하세요.
는 brake chamber converts air pressure into mechanical braking force, and its reliability directly affects the braking effect. Focus on checking whether the air chamber shell is deformed, rusted or cracked, whether the push rod is freely retracted, and whether the dust cover is intact and undamaged. The spring mechanism of the parking brake spring chamber must function normally and the exhaust channel must be unobstructed. The push rod stroke must meet the manufacturer's standards to avoid insufficient braking force or damage to the air chamber.
공기관과 조인트 연결을 단단히 유지하십시오.
는 air pipe connecting the various components in the brake system needs to have sufficient pressure resistance and heat resistance. Check the pipeline for looseness, detachment, rupture, expansion or wear on a daily basis. In particular, the hoses at the chassis or active parts of the vehicle are susceptible to vibration and dust. The connection joints should be tightened reliably, and the quick-connect joints should be cleaned of foreign objects regularly to prevent leakage. Pipes used for a long time should be replaced according to the degree of aging.
비상 브레이크 및 주차 브레이크 시스템을 점검하십시오.
비상 브레이크와 주차 브레이크는 가스가 차단되거나 엔진이 꺼진 경우에도 차량이 안정적으로 정지할 수 있도록 보장하는 중요한 메커니즘입니다. 가스 차단 시 스프링 브레이크 에어 챔버가 자동으로 브레이크를 작동할 수 있는지 일상적인 유지 관리를 통해 확인해야 합니다. 주차 레버나 스위치는 정확하고 민감해야 합니다. 공기압 누출로 인해 차량이 미끄러지는 것을 방지하기 위해 시스템이 차단된 후 주차 압력 유지 용량이 기준을 충족해야 합니다.
압력계 감지 및 경보 장치
는 pressure gauge on the instrument panel is an important basis for the driver to understand the system status. It is necessary to confirm that the pressure gauge display is accurate and without deviation on a daily basis. The high-pressure and low-pressure alarm indicators and buzzers should alarm in time when the air pressure is abnormal. If necessary, check the working status of the electrical circuit and sensor to avoid blind driving caused by the failure of the alarm system.
시스템 공기압 안정성 테스트 수행
엔진을 공회전 속도로 가동하여 공기압 형성 속도를 관찰하고 압축기 출력이 충분한지 확인하십시오. 기준을 충족하려면 엔진이 꺼진 후에도 시스템이 압력 강하 속도를 유지해야 합니다. 브레이크 페달을 수동으로 밟아 브레이크 응답 시간과 압력 강하율을 관찰하여 시스템 응답 능력과 공기 저장 용량을 판단할 수 있습니다.
