Even under normal conditions of use and maintenance, the steel plate spring will produce elastic and fatigue damage. However, if the use of maintenance is not at that time, it will make the steel plate spring early damage. Therefore, the steel plate spring must pay attention to the following problems in the use of:
(1) avoid overloading. Baotou North Benz diesel vehicles in the loading exceeds the prescribed standard or because of unreasonable loading, the spring load increases, produce bending stress, reduce fatigue and damage of steel plate spring.
(2) steady start, try to avoid emergency braking. Baotou North Benz parts diesel car start to balance, because too much too much, the load of steel plate spring is increased, it is easy to cause damage. Diesel vehicle emergency braking, because with the effect of inertia force and braking force, the steel plate spring by bending stress and tensile stress, and the force of the two force, has greatly exceeded the vertical bending stress, emergency braking is the main reason of spring break.
(3) turning slowly. When the diesel engine is changed, the centrifugal force will be generated, the higher the speed of turning, the greater the centrifugal force will be generated. Due to the centrifugal force, increase the lateral steel plate spring steel bearing, rapid change, not only may the accident, but also make the leaf spring leaf spring lateral load increases a lot, because the stress is too large, it is easy to break.
(4) maintain a moderate speed. Diesel vehicles traveling speed is too fast, especially in the rough road to adjust the driving, will increase the deformation of the steel plate spring and increase the number of deformation, resulting in increased bending stress, fatigue and spring break.
Strengthen inspection and maintenance. In use, we should strengthen the inspection and maintenance of the steel plate spring in the northern parts of Baotou. Because of the bad lubrication, the failure of the vibration damper and the loosening of bolts, the steel plate spring can be damaged. Therefore, in the use of steel plate spring should strengthen the inspection and maintenance, found that the problem should be eliminated in time, in order to maintain a good technical condition of the suspension device, effectively extend the service life.
