Correct Maintenance Method For Automobile Leaf Springs

The correct maintenance method can improve the service life of the car leaf spring, avoid and reduce the early damage of the leaf spring. Here are the maintenance methods of the leaf spring:

1. Lubrication of the leaf spring is very important. When the automobile leaf spring bears the load impact, it forms stretching movement, and strong friction occurs between the steel sheets, which causes the temperature of the leaf spring to rise, resulting in surface strain, and presenting small cracks. While the load impact frequency increases, the friction force generated by the stretching movement is also increasing. When the fatigue limit is reached at the stress concentration point, the single piece or the whole pair will be broken. Apart from other reasons, the main reason for the fracture of leaf spring is poor lubrication, which should be paid attention to by the driver and technical management personnel, and the lubrication of leaf spring should be done in a timely manner.

2. During regular maintenance, attention should be paid to the fastening of the riding bolts and center bolts. If damaged, it should be replaced in a timely manner. If a car leaf spring is found to be broken, it should be replaced with a product of the same specification and reliable quality in a timely manner. Do not randomly assemble it.

3. Avoid overloading or partial loading. When the road condition is poor, the vehicle speed should be controlled to drive smoothly. When turning, the vehicle speed should be slowed down, and the turning should not be too fast. During the driving process, the engine's exhaust braking should be used more, and emergency braking should be used less.

To sum up, the drivers and maintenance personnel of heavy transport vehicles should pay more attention to the leaf spring during driving and during vehicle maintenance, so as to avoid unnecessary loss to the vehicle due to the breaking of the leaf spring.
