Damping adjustment device suitable for hydraulic damper
2016
The invention discloses a damping adjustment device suitable for a hydraulic damper. The hydraulic damper comprises a cylinder barrel and a piston assembly arranged in the cylinder barrel. The damping adjustment device comprises a pressure adjustment valve and a driving mechanism connected with the pressure adjustment valve, wherein the pressure adjustment valve is used for providing pressure oil for the piston assembly, and the pressure oil is used for adjusting the magnitude of the clearance between the piston assembly and the inner wall of the cylinder barrel. According to the damping adjustment device suitable for the hydraulic damper, the pressure oil is provided for the hydraulic damper by arranging the pressure adjustment valve and used for adjusting the magnitude of the clearance between the piston assembly inside the hydraulic damper and the inner wall of the cylinder barrel, and the magnitude of the opening degree of a damping channel can be adjusted, so that the damping force of the damper is changed, and the damping adjustment purpose is achieved.
