Description

A New Type of Shock Absorber for Automobile

technical field

The utility model relates to the technical field of shock absorbers, in particular to a novel shock absorber for automobiles.

Background technique

The shock absorber is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface. When passing through the uneven road surface, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will reciprocate, and the shock absorber is used To suppress this kind of spring jumping, the shock absorber is too soft, and the vehicle body will jump up and down; if the shock absorber is too hard, it will bring too much resistance, which will hinder the spring from working normally. Matching, and the hardness of the spring is closely related to the weight of the car.

However, the existing automobile shock absorbers have simple structural design and poor shock absorption effect. They are bumped during the driving process of the automobile, and each part of the automobile relies on different axles to move. When the automobile vibrates, the axle The rod will also be vibrated, and the vibrating shaft rod is not conducive to the transmission of power. If it is affected by vibration for a long time, the shaft rod will be easily damaged, and driving accidents will easily occur, which will endanger the life safety of drivers.

Therefore, how to design a new type of shock absorber for automobiles has become a problem we have to solve at present.
