Abstract

The invention discloses a novel electric vehicle damper which comprises a damper shell. The damper shell is provided with a piston cavity, a damping piston shaft is installed in the piston cavity in a sliding manner, a damping barrel is arranged in the piston cavity, a reset spring is arranged in the damping barrel, a lubricating oil inlet channel is formed in the damper shell, and an oil storage groove is formed in the side, located on the lubricating oil inlet channel, of the damper shell; the damping barrel is located between the oil storage groove and the piston cavity and is provided with a plurality of through holes, and a lubricating oil outlet channel is formed in the side, far away from the lubricating oil inlet channel, of the damper shell; a piston of the damping piston shaft is provided with a damping channel for communicating the two sides of the piston of the damping piston shaft; and the novel electric vehicle damper further comprises a damping mat. According to the novel electric vehicle damper, through the unique structural design and unique selection of the damping mat, many beneficial effects are achieved, and the good application prospect and industrial production potential are achieved in the field of electric vehicles and dampers.

Description

technical field [0001] The invention relates to a shock absorber, more particularly relates to an electric vehicle shock absorber, and belongs to the technical field of shock absorbers. Background technique [0002] It is known that in order to quickly attenuate the vibration of the vehicle frame and the vehicle body and improve the ride comfort and comfort of the electric vehicle, the suspension system of the electric vehicle is generally equipped with a shock absorber. Shock absorbers are vulnerable parts during the use of electric vehicles. Their working conditions and performance will directly affect the driving stability of electric vehicles and the life of other parts. In order to achieve long-term ride comfort, shock absorbers 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 absorbing the shock and the impact from the road sur...
