Abstract

The invention provides a shock absorber, a vehicle suspension and a vehicle. The shock absorber comprises an oil storage cylinder, a work cylinder arranged in the oil storage cylinder, a piston rod, a piston assembly aranged in the work cylinder and installed at the lower end of the piston rod in a sleeving mode, a cylinder base in seal connection with the oil storage cylinder, and a bottom valve assembly arranged on the cylinder base. The work cylinder is divided into an upper cavity and a lower cavity by the piston assembly. The bottom valve assembly is arranged in the lower cavity. The piston rod is provided with a liquid flow hole through which the upper cavity communicates with the lower cavity. A lower end opening of the liquid flow hole is open. An upper end opening of the liquid flow hole is covered with a clamping type valve plate. According to the shock absorber, the maneuverability and riding comfort of the vehicle can be both taken into account.

Description

technical field [0001] The invention belongs to the technical field of vehicle suspension systems, and in particular relates to a shock absorber, a vehicle suspension and a vehicle. Background technique [0002] The shock absorber is an important part of the vehicle suspension system, which plays a role in buffering the impact of the road, attenuating the vibration of the suspension and the body, and directly affects the handling and comfort of the vehicle. The performance of the shock absorber can be specifically quantified by the F-V curve (damping force-speed curve). [0003] The structure adopted by the existing shock absorber is basically a double cylinder shock absorber. Such as figure 1 As shown, it is an existing double-tube shock absorber. In this double-tube shock absorber, the damping force in the compression stroke is mainly realized by a bottom valve assembly 1a at the bottom of the cylinder (generated in the bottom valve compression stroke) The F-V curve of ...
