Abstract

The invention discloses a shock absorber applied to a vehicle and the vehicle provided with the shock absorber. The shock absorber applied to the vehicle comprises a cylinder and a rod system component, wherein a cavity is formed in the cylinder, the cavity contains a medium, the rod system component at least is partially located in the cavity, the rod system component divides the cavity into a working cavity and a decompression cavity, and the rod system component is provided with a decompression channel. According to the formation of the decompression channel, when pressure in the working cavity is not smaller than a preset pressure threshold, the decompression channel is opened, and the working cavity communicates with the decompression cavity through the decompression channel; and whenthe pressure in the working cavity is smaller than the preset pressure threshold, the decompression channel is closed. Through the arrangement of the decompression channel, when the shock absorber moves at high frequency, after the pressure in the working cavity reaches the preset pressure threshold, the decompression channel is opened, the working cavity communicates with the decompression cavity through the decompression channel, therefore, flowing of the medium from the working cavity to the decompression cavity can be accelerated, then damping force of the shock absorber can be quickly lowered, and good comfort of the vehicle is guaranteed.

Description

technical field [0001] The invention relates to the field of shock absorbers, in particular, to a shock absorber for a vehicle and a vehicle with the same. Background technique [0002] The shock absorber is the damping element of the vehicle's suspension system, and its parameter settings affect the vehicle's handling stability and ride comfort. When the vehicle is designed, it is expected that the shock absorber can have a larger damping force value when the shock absorber is running at a low frequency (for example: a relatively flat road surface), so as to ensure better handling stability of the vehicle. (For example: relatively bumpy road surface) When running, it is expected that the shock absorber has a smaller damping force value, so that the comfort of the vehicle can be improved. [0003] However, when the existing shock absorber operates at a high frequency, its damping force value is relatively large, resulting in poor comfort of the vehicle. Contents of the in...
