The suspension has a great effect on the main performance of cars, such as running smoothness, operational stability, vehicles throughput capacity and fuel economy, etc. 4.In the process of moving, the car will vibrate and spring deflection will increase because of uneven road and the change of car speed, so the life of leaf springs, body, frame and other parts will by reduced. In order to attenuate vibration of cars and improve the ride of the automobile, the shock absorber is attached. The shock absorber is telescopic shock absorber and installed in parallel with suspension and leaf spring to absorb the vibration when leaf springs rise and fall, which can make cars rapidly recover to smooth state and improve the running smoothness of cars The components of suspension 1.Consists of the leaf spring and the shock absorber 2.The leaf spring is piled up by several steels. The center of leaf spring is fixed to the steel seat of real axle case by the assay of rear press plate with bumper block assembly, u-shaped spiral and u-bolt plate. In order to prevent steels from slipping out of place，some clamps are used to fix them. The two ends of the longest steel was curved to spring eye in order to install the spring on the live elements of the frame, such as side rails. 3.The absorber connec
