Embodiment Construction

[0025] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.

[0026] Such as figure 1 and figure 2 As shown, the variable damping shock absorber includes an oil storage barrel 3, and also includes a working cylinder 5 located in the oil storage barrel 3 and a piston rod 1 extending into the working cylinder 5 and connected to a piston 8. In the working cylinder 5 A cylinder liner 6 whose outer wall is bonded to the inner wall of the working cylinder 5, and the inner wall of the cylinder liner 6 is bonded to the outer wall of the piston 8; when the piston 8 moves on the cylinder liner 6, the working cylinder 5 is divided into an upper chamber with a variable volume and an upper chamber with a variable volume. Throttle groove 4 in the lower chamber.

[0027] The piston 8 is connected to the piston rod 1 by a screw, and the piston 8 moves up and down ...

Abstract

The invention discloses a variable damping shock absorber which comprises an oil storage barrel, a working cylinder and a piston rod, wherein the working cylinder is arranged in the oil storage barrel, and the piston rod extends into the working cylinder and is connected with a piston. A cylinder sleeve is arranged in the working cylinder, the outer wall of the cylinder sleeve is attached to the inner wall of the working cylinder, and the inner wall of the cylinder sleeve is attached to the outer wall of the piston. The cylinder sleeve is provided with a throttling groove used for dividing the working cylinder into an upper cavity and a lower cavity in the piston movement process, and the volume of the upper cavity and the volume of the lower cavity are variable. According to the variable damping shock absorber, damping can carry out self-adjustment according to the motion stroke of the piston, and the handling stability and riding comfort of a car can be improved greatly; in addition, the variable damping shock absorber is simple in adjusting structure and easy and convenient to control.

Description

technical field [0001] The invention relates to a shock absorber for automobiles, in particular to a variable damping shock absorber. Background technique [0002] In the vehicle suspension system, the main function of the shock absorber is to accelerate the attenuation of the vibration of the frame and the body, so as to improve the ride comfort of the vehicle and improve the ride comfort of passengers. For automobiles, excellent ride comfort and operational stability are crucial, and the important component that affects the characteristics of the suspension system is the shock absorber. The ideal variable damping shock absorber is to improve the ride comfort and ride quality of the car. An essential element of comfort. [0003] At present, the damping adjustable shock absorbers that adjust the viscosity coefficient of oil include: electrorheological fluid shock absorbers and magnetorheological fluid shock absorbers. Adjustable damping shock absorbers for adjusting the ar...
