The clutch disc, pressure plate, and release bearing are the main components of the clutch. The degree of wear of these components will affect the performance of the clutch. For example, in the case of frequent shifting, the wear of the clutch disc will accelerate and needs to be checked and replaced regularly.
- Transmission gear: The transmission adjusts different transmission ratios through different gear combinations to meet the needs of the vehicle under different driving conditions. The precision and strength requirements of transmission gears are very high. Once there is wear or damage, it will lead to difficulties in shifting gears and abnormal noises.
- Drive shaft and universal joint: The drive shaft transmits the power of the engine to the rear axle. The universal joint allows the drive shaft to rotate within a certain angle range to adapt to the bumps and turns of the vehicle. The balance and connection reliability of the drive shaft and universal joint are crucial to the driving stability and safety of the vehicle.
-
Braking system spare parts
- Brake disc and brake pad: The brake disc and brake pad are the key components of the braking system. They generate braking force through friction to slow down or stop the vehicle. The material and processing precision of the brake disc will affect the braking effect and heat dissipation performance. The friction coefficient and wear resistance of the brake pad are directly related to the reliability and service life of braking.
- Brake air pump and brake valve: For heavy trucks using pneumatic braking, the brake air pump is the key component that provides braking pressure. The brake valve is responsible for controlling the magnitude and distribution of braking pressure. The performance and reliability of these components directly affect the response speed of the braking system and the magnitude of braking force.
- Brake pipeline and joint: The brake pipeline and joint are responsible for transmitting the braking pressure generated by the brake air pump to the brake disc or brake drum. If there is a leak in the brake pipeline or the joint is loose, it will lead to brake failure and seriously endanger driving safety.
-
Suspension system spare parts
- Leaf spring: The leaf spring is an important part of the suspension system of heavy trucks. It has the functions of bearing the weight of the vehicle body and buffering the impact of the road. The number of leaves, thickness, and elastic coefficient of the leaf spring will affect the carrying capacity and comfort of the vehicle.
- Shock absorber: The shock absorber can reduce the vibration and bump of the vehicle during driving, improve driving comfort and vehicle stability. The damping force and rebound speed of the shock absorber need to be selected according to the type and use environment of the vehicle.
- Air spring: The air spring is a new type of suspension component with the advantages of adjustable height and good comfort. More and more heavy trucks are starting to use air spring suspension systems. The quality and reliability of the air bag, control valve and other components of the air spring are crucial to the performance of the suspension system.
-
Electrical system spare parts
- Battery: The battery is the energy source of the electrical system of heavy trucks and provides power for vehicle starting, lighting, audio and other equipment. The capacity and discharge performance of the battery will affect the starting ability and normal operation of electrical equipment.
- Generator: The generator is responsible for charging the battery and providing power for electrical equipment while the vehicle is running. The output power and voltage stability of the generator need to meet the needs of the vehicle.
- Various sensors and controllers: Heavy trucks are equipped with various sensors and controllers, such as water temperature sensor, oil pressure sensor, vehicle speed sensor, ABS controller, etc. These components can monitor the running status of the vehicle in real time and feed back the information to the driver or vehicle control system so that corresponding measures can be taken in time.
