Description

A car suspension with multi-stage damping device

technical field

The utility model belongs to the technical field of automobile chassis structures, and in particular relates to an automobile suspension with a multi-stage damping device.

Background technique

Automobile suspension is a crucial structure of the automobile. The automobile suspension plays the role of connecting the wheels and the body. Generally speaking, the automobile suspension system is mainly composed of shock absorbing devices, guiding devices and elastic elements. The function of the automobile suspension system is to transmit the force and moment acting between the wheel and the frame, and buffer the impact force transmitted from the uneven road to the frame or body, and attenuate the vibration caused by it, so as to ensure the smooth running of the car. When the car is running on a curve, it is hoped that the car suspension system has a certain rigidity to prevent the car from over-rolling. At the same time, the suspension system can also adjust the rotation angle of the wheels. On the basis of satisfying the above performance, it is also required that the automobile suspension system occupies as little space as possible to achieve a reasonable layout of the automobile chassis. To sum up, a good car suspension system can have a good shock absorption effect on bumpy roads, and at the same time have a certain degree of rigidity when cornering, so that the car will not be too soft or too hard during driving, and The automobile suspension system also has the characteristics of taking up less space, which has higher requirements for the structure of the suspension system. The automobile suspension system has always been the most difficult part of the automobile, and major automobile manufacturers have been continuously improving and optimizing the suspension system in order to obtain an automobile suspension system with excellent performance, safety, reliability, and cost-effectiveness.
