Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of dampers, in particular, the invention relates to a damping adjustment device suitable for hydraulic dampers. Background technique [0002] At present, certain achievements have been made in the research and development of dampers, and dampers have already played a role that cannot be underestimated in our lives. Dampers can be divided into spring dampers, hydraulic dampers, pulse dampers, rotary dampers, wind dampers and viscous dampers. Among them, the spring damper cannot absorb energy well and dissipate energy effectively, and the spring expands and contracts many times, which is easy to produce plastic deformation. Hydraulic dampers cannot effectively control low-frequency high-amplitude vibrations or high-frequency low-amplitude vibrations. A pulsation damper is a hydraulic vessel whose operating range is extremely limited due to limitations in materials, manufacturing techniques, and practical app...
