钢板弹簧作为机动车车桥与车架的弹性连接件,缓冲并吸收了车辆运行中的冲击和振动能量,是重要的减振装置。由于道路等级差异较大,以及车辆常处于超载状态,加之对钢板弹簧的维护与使用不当等诸多因素,钢板弹簧容易过早损坏。因此,必须正确使用与维修,延长其使用寿命。 As a flexible connecting piece between axle and frame of a motor vehicle, the leaf spring is an important damping device that buffers and absorbs the impact and vibration energy of the vehicle in operation. Due to the large differences in the road level, as well as vehicles often in overload conditions, coupled with the maintenance and improper use of leaf springs and many other factors, leaf springs tend to premature damage. Therefore, it must be properly used and repaired to extend its service life.
