A shock absorber for new energy vehicles

Abstract

The invention discloses a damper used for a new energy automobile. The damper comprises a shell, a groove, a first filter net, a first breathing hole, a first guide hole, a first guide column, a firstseal ring, first shafts, first conical surfaces, an oil cavity, a piston, communicating holes, second shafts, second conical surfaces, an upper connecting base, a top cover, a second guide column, asecond guide hole, a second seal ring, a seal gasket and the like. The damper used for the new energy automobile is reasonable and simple in structure and low in production cost, damping is achieved under the double effects of a hydraulic mode and springs, the damping effect is good, and meanwhile, the phenomenon that a simplex elastic damping mode is adopted and causes elastic attenuation, and the damping effect is instable in use is also avoided; in addition, the phenomenon that a lot of heat is produced in the using process and the service lives of parts are shortened is avoided; and furthermore, the first conical surfaces are big-end-down conical surfaces, the second conical surfaces are big-end-up conical surfaces, accordingly, it is guaranteed that the larger the amplitude of the up-down movement of the piston, the larger the resistance of flowing of hydraulic oil, of the upper and lower sides of the piston, through the communicating holes, and therefore, the hydraulic damping effect is improved.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a shock absorber for a new energy vehicle. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technologies and new structures; in order to quickly attenuate the vibration of the frame and body and improve the ride comfort and comfort of the car, the suspension system of the car is generally equipped with a shock absorber, and the two-way effect is widely used in the car. Barrel shock absorber; because the shock absorber is in a continuous compression and stretching process during work; ordinary elastic shock absorbers will cause elastic attenuation during long-term use, and the shock absorption effect is unst...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a shock absorber for new energy vehicles in order to solve the above problems, which solves the problem that ordinary elastic shock absorbers will cause elastic attenuation during long-term use, and the shock absorption effect is unstable during use. The shock absorber will generate a lot of heat during use, which will reduce the service life of parts
