Abstract

The invention discloses a novel shock absorber of an electric automobile. The novel shock absorber comprises a buffer shell, wherein the buffer shell is provided with a piston cavity; a buffer piston shaft is slidably installed in the piston cavity; a damping barrel is arranged in the piston cavity; a return spring is arranged in the damping barrel; a lubricant oil inlet channel is formed in the buffer shell; an oil storage groove is formed in the buffer shell and located in one side of the lubricant oil inlet channel; the damping barrel is located between the oil storage groove and the piston cavity; a plurality of through holes are formed in the damping barrel; a lubricant oil outlet channel is formed in the buffer shell and located in one side away from the lubricant oil inlet channel; a damping channel communicating the two sides of a piston of the buffer piston shaft is formed in the piston of the buffer piston shaft; and a buffer pad is further comprised. Many beneficial effects are obtained through a unique structural design and unique selection for the buffer pad; and the novel shock absorber has good application prospect and industrialized production potential in the field of electric automobiles and the field of shock absorbers.

Description

technical field [0001] The invention relates to a shock absorber, more particularly, to a new type of shock absorber for electric vehicles, which belongs to the technical field of shock absorbers. Background technique [0002] It is well known that, in order to rapidly attenuate the vibration of the frame and the body and improve the ride comfort and comfort of the electric vehicle, shock absorbers are generally installed on the suspension system of the electric vehicle. The shock absorber is a vulnerable part during the use of electric vehicles. Its working conditions and work quality will directly affect the stability of electric vehicles and the life of other parts. In order to achieve long-term riding comfort, shock absorption The device also needs to be in good working condition for a long time. [0003] The working principle of the shock absorber is mainly used to suppress the shock when the spring rebounds after shock absorption and the impact from the road surface, ...
