Embodiment Construction
[0018] Such as figure 1 As shown, a shock absorber with adjustable damping force of the present invention includes an upper suspension ring 1, a base 8, a shock absorber spring 11, a working cylinder 7 filled with damping oil, a liquid storage cylinder, and a shock absorber with adjustable damping force. Vibrator piston assembly, one end of the shock absorber piston assembly is connected with the upper suspension ring 1, and the other end is connected with the working cylinder 7. The connecting relationship between the remaining parts is the same as the shock absorber of the prior art. The upper suspension ring 1 is connected with the vehicle frame, and the working cylinder 7 is installed in the liquid storage cylinder, and is compressed with a nut through the sealing ring and the guide seat, and is connected with the vehicle frame. The base 8 that the vehicle axle connects is located at the lower end of the liquid storage cylinder. The shock absorber spring 11 is sleeved on ...

The invention discloses an absorber for adjusting a damping force. The absorber provided by the invention comprises an upper rings, an absorber spring, a working cylinder, a solution-storing tank, and an absorber piston assembly with adjustable damping force, wherein one end of the absorber piston assembly is connected with the upper rings, and the other end of the absorber piston assembly is connected with the working cylinder; the absorber piston assembly comprises a hollow piston rod and a piston valve assembly which is stretched into the working cylinder, the upper end of the hollow piston rod is mutually connected with the upper rings, and the lower end of the hollow piston rod is mutually connected with the piston valve assembly; the lower part of the hollow piston rod is provided with a radial ostiole of the upper cavity and lower cavity of the working cylinder which is communicated with a center hole, the center hole is provided with a moving valve rod, and a damping adjusting rotating valve is arranged in the rings and used for pushing the moving valve rod so as to adjust the opening of the radial ostiole; the technical scheme is adopted, the moving valve rod is taken as a control executive device, and a damping adjusting knob is rotated so as to adjust the work damping of the absorber; the absorber provided by the invention has the advantages of simple damping adjustment, simple structure, and no needing a complicated sensor or an electronic component, low addition cost, and convenience in application and popularization.
Description
technical field [0001] The invention belongs to the technical field of auto parts manufacturing, in particular, the invention relates to a shock absorber mainly used as a shock absorber in a vehicle suspension system with adjustable damping force. Background technique [0002] Shock absorber is an important part of the car, and its performance directly affects the comfort, handling stability and safety of the car. At present, the passive suspension usually adopts ordinary double-tube hydraulic shock absorbers. Since the damping cannot be adjusted, the damping characteristics of the suspension system cannot be adjusted according to the road conditions, vehicle operating conditions or load capacity, and the ideal damping effect cannot be achieved. Vibration effect and handling stability. [0003] For this reason, various electronically controlled suspension systems have emerged as the times require. Electronically controlled suspensions can not only isolate road vibration wel...
