ブレーキの安全ラインの構築：エアブレーキシステムの構成とメンテナンスの詳細

トラックのエアブレーキシステムの主なコンポーネントは何ですか?

の トラック用エアブレーキシステム 大型車両の安全運転を保証する重要な要素です。圧縮空気を利用してブレーキ装置を駆動し、効率的で信頼性の高いブレーキ効果を実現します。このシステムは複雑な構造をしており、さまざまな専門的なコンポーネントで構成されています。さまざまな部品が相互に連携して、さまざまな作業条件下でも車両が安定してブレーキをかけることができます。
エアコンプレッサー
の 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.
エアドライヤー
の 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.
エアタンク
の 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.
ブレーキバルブ（フットブレーキバルブ）
の 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.
ブレーキエアチャンバー
の 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.
スプリングブレーキチャンバー
の 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.
ブレーキコネクティングロッドとレギュレーター
の 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.
ブレーキライン
の 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.
安全弁
の 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.
補助装置
の 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.

ブレーキチャンバーはどのようにして空気圧を機械力に変換するのでしょうか?

の 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.
ブレーキチャンバーの基本構造
の 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.
空気圧室とスプリング室の機能的区別
の 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.
空気圧を機械力に変換する動作原理
運転者がブレーキペダルを踏むと、ブレーキバルブがブレーキ空気室の空気圧室に圧縮空気を導入する。空気圧室内の空気圧が急激に上昇し、ダイヤフラムの表面に作用して推力が発生します。推力の大きさは空気圧とダイヤフラムの面積に比例します。ダイヤフラムは空気圧の作用により外側に拡張し、接続されたプッシュロッドを押して軸方向に移動させます。プッシュロッドの動きによりコネクティングロッドと調整機構が駆動され、空気圧エネルギーが機械力に変換され、その機械力がブレーキシューまたはブレーキパッドに加えられ、ブレーキドラムまたはブレーキディスクがクランプされます。
プッシュロッドの動きを機械的に伝達
の 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.
の difference between diaphragm and piston and their influence
の 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.
スプリングブレーキチャンバーの特別な機能
の 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.
ブレーキ室の気密性と応答速度
の 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.
ブレーキチャンバーのメンテナンスと故障の症状
ブレーキチャンバーダイヤフラムの破損、プッシュロッドの詰まり、スプリングの疲労などの一般的な故障は、ブレーキの故障やパーキングブレーキの故障につながる可能性があります。空気室の気密性を定期的にチェックし、プッシュロッドのストロークやスプリングの状態を検出することが、ブレーキシステムの信頼性を確保する鍵となります。空気圧テストと漏れ検出により、隠れた危険を事前に検出し、運転事故を回避できます。

エアドライヤがエアブレーキシステムにとって重要な理由

エアドライヤーs 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.
圧縮空気中の水分とその危険性
の 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.
エアドライヤーの動作原理
エアドライヤーs 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.
ブレーキシステムの氷上故障の防止
低温環境では、空気パイプライン内の水分が非常に凍結しやすく、ブレーキバルブや空気室が詰まり、ブレーキの故障や車両の制御不能の原因となることがあります。エアドライヤーは水分を効果的に除去し、凝縮水の蓄積を防ぎ、氷詰まりのリスクを大幅に軽減します。特に寒冷地や冬季に走行する車両においては、車両のブレーキの安全性と安定性を直接的に確保するエアドライヤーの重要性が顕著です。
ブレーキシステムの主要コンポーネントを保護
の 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.
システムの空気圧の安定性と応答速度の向上
水分が多すぎると空気圧の変動や漏れが発生し、ブレーキシステムの気密性や空気圧の安定性に影響を与える可能性があります。エアドライヤは、エアタンクやパイプラインに入る空気を乾燥した純粋な状態に保ち、安定した空気圧を供給します。安定した空気圧はブレーキチャンバーの効率的な動作をサポートし、ブレーキの応答速度と制動力を向上させ、運転の安全性を向上させます。
メンテナンスの困難さとコストを軽減する
エアドライヤーのないシステムや乾燥効果が低いシステムでは、頻繁な排水、パイプの清掃、腐食や損傷した部品の交換が必要となり、メンテナンスの頻度とコストが増加します。エアドライヤは、自動的に除湿と排水を行うことで、手動による介入とメンテナンスの作業負荷を軽減します。システムの故障率が減少し、車両の走行時間が増加し、運用コストが大幅に削減されます。
エアドライヤーの種類と適用シーン
一般的なエアドライヤには、吸着式ドライヤや冷凍式ドライヤなどがあります。吸着式ドライヤーは乾燥剤を介して水分を吸収するため、構造が簡単でトラックのエアブレーキシステムに広く使用されています。冷凍式ドライヤーは、空気温度を下げることで水分を凝縮させて排出するため、特殊な環境要件に適しています。さまざまなタイプのドライヤーを車両の動作環境や作業条件と組み合わせて、最適な乾燥効果を確保するために適切なモデルを選択します。
エアドライヤーのメンテナンスのポイント
乾燥剤の飽和障害を防ぐため、乾燥剤は定期的に交換する必要があります。凝縮水や不純物を適時に除去するには、ドレンバルブの機能を正常に維持する必要があります。エアドライヤのハウジングとインターフェースに漏れがないか、シール性能が良好かどうかを確認する必要があります。不適切なメンテナンスはドライヤーの故障の原因となり、ブレーキシステム全体の安全性能に影響を与えます。

ブレーキバルブ（フートバルブ）はどのようにしてブレーキエア圧を制御しているのですか？

の 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.
ブレーキバルブの基本構造
の 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.
ブレーキバルブの動作原理
ドライバーがブレーキペダルを踏むと、ペダルストロークに応じてブレーキバルブ内のピストンが前進します。ピストンの動きにより弁体内の空気回路の開閉状態が変化し、エアタンクからブレーキ室の空気圧室へのエアを制御します。ペダルを深く踏むほどバルブが開き、ブレーキ室に入る空気圧が高くなります。増加した空気圧によってブレーキ室のダイヤフラムまたはピストンが押され、機械的推力が発生してブレーキがかかります。ペダルを放すとピストンがリセットされ、空気回路が閉じられ、空気圧が解放され、ブレーキが解放されます。
ブレーキ空気圧調整の正確な制御
の 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.
マルチウェイエア回路設計と安全保証
の 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.
ブレーキバルブの応答速度とシール性
の 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.
フットブレーキバルブとパーキングブレーキシステムの連携
の 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.
ブレーキバルブのメンテナンスと故障の症状
ブレーキバルブシールの老朽化、ピストンの詰まり、またはスプリングの故障が一般的な故障の原因です。これにより、空気圧調整が鈍くなり、空気漏れや不均一なブレーキが発生します。ブレーキバルブの気密性、ペダルの動き、内部部品の状態を定期的に点検し、正常な性能を確保してください。欠陥が見つかった場合は、安全上の危険を避けるために、適時に修理または交換する必要があります。

安全弁はエアブレーキシステムにおいてどのような役割を果たしますか?

の 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.
の basic structure and principle of the safety valve
の 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.
空気圧の上限を制御してシステムの過圧を防止します
の 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.
エアコンプレッサーと空気回路コンポーネントを保護します。
の 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.
車両ブレーキシステムの安定した機能を確保する
の 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.
の rationality of the set pressure value and the system match
の 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.
安全弁の設置場所と作用範囲
の 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.
安全弁の材質と耐久性の要件
安全弁s 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.
安全弁の保守点検と故障リスク
安全弁s 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.
安全弁と圧力調整システムの連携
エアブレーキシステムには通常、連携して動作する圧力レギュレーター、圧力スイッチ、安全バルブが装備されています。圧力レギュレータはコンプレッサーの起動と停止を制御し、圧力スイッチは空気圧のフィードバックを監視し、安全弁は複数の安全機構が確実に有効であることを保証する冗長保護装置として使用されます。安全弁の設計と調整は、誤作動や機能の重複を回避し、システム全体の安全性を向上させるために、空気圧制御システム全体と調整する必要があります。

エアブレーキシステムの日常メンテナンスの優先事項は何ですか?

大型車両（トラック、バス、トレーラーなど）の重要な安全装置であるエアブレーキシステムの動作安定性は、車両全体のブレーキ効果や交通安全に直接関係します。このシステムは、エアコンプレッサー、エアリザーバー、ドライヤー、ブレーキバルブ、ブレーキエアチャンバー、エアパイプ、各種制御部品で構成されています。構造が複雑で頻繁に動作します。科学的かつ標準化された日常メンテナンスは、システムの寿命を延ばすだけでなく、突然のブレーキ故障を効果的に防ぐことができます。
システムの気密性を確認してください
の 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.
エアタンク内の水や不純物を定期的に排出してください。
の 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.
エアドライヤーの作動状態を確認してください
の 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.
ブレーキバルブの応答性を維持する
の 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.
ブレーキチャンバーとプッシュロッドの状態を確認してください
の 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.
エアパイプとジョイントの接続をしっかりと維持する
の 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.
非常ブレーキと駐車ブレーキシステムを点検してください
非常ブレーキと駐車ブレーキは、ガソリンを遮断したりエンジンを停止したりした場合でも、車両を確実に停止できるようにする重要な機構です。日常のメンテナンスでは、ガスが遮断されたときにスプリング ブレーキ エア チャンバーが自動的にブレーキを掛けることができるかどうかを確認する必要があります。パーキングレバーまたはスイッチは正確で敏感である必要があります。システム遮断後の駐車圧力維持能力は、空気圧漏れによる車両の滑りを防止する基準を満たす必要があります。
圧力計の検知と警報装置
の 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.
システムの空気圧安定性テストを実行する
エンジンをアイドル回転数で運転して空気圧の上昇速度を観察し、コンプレッサーの出力が十分であるかどうかを確認します。システムは、基準を満たすためにエンジンを停止した後も圧力降下速度を維持する必要があります。ブレーキペダルを手動で踏むことにより、ブレーキの応答時間と圧力降下率を観察し、システムの応答能力と空気貯蔵容量を判断できます。
