Description

Technical Field

[0001] The present invention relates to the field of automobile design and manufacture, and more particularly to an automobile suspension. Background Art

[0002] Suspension is the general term for all force-transmitting connection devices between the frame (or load-bearing body) and the axle (or wheel) of a car. Its function is to transmit the force and torque acting between the wheel and the frame, and to buffer the impact force transmitted to the frame or body by the uneven road surface, and reduce the vibration caused thereby, so as to ensure that the car can run smoothly. Usually, the suspension of a car uses shock-absorbing components to alleviate the impact force on the frame or body. The number and setting position of the shock-absorbing components are usually set corresponding to the tires. In general, each set of shock-absorbing components only uses a single shock absorber to achieve shock absorption, so when the tire When the impact force is large, the shock absorber can perform a good buffering job. However, when the impact force received by the tire is small, since a single shock absorber cannot accurately adapt to various road conditions, the shock absorber may react too slowly or too sensitively. When the shock absorber reacts too slowly, the shock absorber's movement range will be smaller and the suspension will be stiffer overall. When the shock absorber reacts too sensitively, the shock absorber's movement range will be larger. Regardless of whether the shock absorber reacts too sensitively or too slowly, the suspension will not be able to alleviate the impact force effectively, resulting in a poor riding experience for the vehicle's drivers and passengers.
