A shock absorber for a new energy vehicle

Abstract

The invention belongs to the technical field of shock absorbers and particularly relates to a shock absorber for a new energy automobile. The shock absorber comprises a shock absorbing shell, an end cover, a shock absorbing rod, springs and damping modules. The lower end of the shock absorbing shell is connected with the end cover through a thread, and the shock absorbing rod is slidably mounted in a center hole of the end covert. The first spring is arranged between the end face of the upper end of the shock absorbing rod and the shock absorbing shell, and the second spring is arranged between a shaft shoulder in the shock absorbing rod and the end cover. A set of transmission gears is arranged on the cylindrical face of the upper end of the shock absorbing rod, and the shock absorbing rod is in transmission with the damping modules through the transmission gears. The damping modules are arranged on the peripheries of the transmission gears on the shock absorbing rod and used for enabling the shock absorbing rod to have reverse damp. The springs are arranged above the shock absorbing rod, thus external impact force borne by the shock absorbing rod is absorbed; and the damping modules are arranged on the peripheries of the transmission gears on the shock absorbing rod, thus resilience force of the springs can be absorbed by the damping modules, and then the automobile has the effect of filtering vibration of bumpy road surfaces.

Description

technical field [0001] The invention belongs to the technical field of shock absorbers, in particular to a shock absorber for new energy vehicles. Background technique [0002] Shock absorber is a device that uses damping characteristics to slow down mechanical vibration and consume kinetic energy. It is commonly used in the suspension system of cars and motorcycles, and some bicycles also have shock absorbers. [0003] In the automobile suspension system, the elastic elements vibrate due to the impact. In order to improve the ride comfort of the car, shock absorbers are installed in parallel with the elastic elements in the suspension. The working principle of the shock absorber is that when the frame (or body) and the axle vibrate and there is relative movement, the piston in the shock absorber moves up and down, and the oil in the shock absorber chamber repeatedly passes through different chambers. The pores flow into another cavity. At this time, the friction between ...

AI Technical Summary

Problems solved by technology

[0005] When the temperature of the existing shock absorber is too high, heat decay will occur, the damping will be weakened, and the shock absorption performance will be greatly reduced, which will affect the shock absorption effect of the shock absorber; and the shock absorption amount cannot be adjusted during use; in addition , due to the frequent vibrations of the vehicle during driving, the shock absorber absorbs a large amount of heat, resulting in a decrease in the concentration of hydraulic oil, which in turn causes oil leakage, and at the same time causes a lot of pollution
