Abstract

The invention discloses a self-adaptive vehicle vibration damper based on stepless regulation. The self-adaptive vehicle vibration damper comprises a working cylinder barrel and a piston unit, and theworking cylinder barrel is internally provided with a detection unit; and the detection unit comprises a first detection rod piece, a first detection groove body, a first diverter valve, a second detection rod piece, a second detection groove body and a second diverter valve. According to the self-adaptive vehicle vibration damper based on stepless regulation, the vibration damper can automatically open the first diverter valve or the second diverter valve according to the bumping intensity in the vehicle running process so that the running comfort of a vehicle under the poor road condition can be improved.

Description

technical field [0001] The invention relates to the field of vehicle engineering, in particular to an adaptive vehicle shock absorber based on stepless regulation. Background technique [0002] The suspension system of a car refers to the support system between the body and the axle, among which the shock absorber is one of the necessary components to form the suspension system. The function of the shock absorber is to accelerate the attenuation of vibration between the body and the axle through the movement of the damping medium inside the shock absorber, thereby improving the stability of the vehicle during driving. Therefore, the working performance of the shock absorber will directly affect The driving comfort of the vehicle. [0003] At present, the movement mode of the damping medium inside the shock absorber in the related art is mostly fixed, that is, the path through which the damping medium can flow inside the shock absorber is fixed, and the vehicle usually suffe...
