Abstract

The invention discloses a damping-adjustable damping device which comprises a hydraulic damper and a damping adjustment device. The hydraulic damper comprises a cylinder barrel, a piston rod and a piston assembly arranged in the cylinder barrel. The damping adjustment device is connected with the hydraulic damper and used for providing pressure oil for the piston assembly, wherein the pressure oil is used for adjusting the size of the clearance between the piston assembly and the inner wall of the cylinder barrel. According to the damping device, the damping adjustment device is arranged to provide the pressure oil for the hydraulic damper so as to adjust the size of the clearance between the piston assembly in the hydraulic damper and the inner wall of the cylinder barrel, and therefore the opening degree of a damping channel can be adjusted, then the damping force of the damper is changed, and the aim of adjusting damping is achieved.

Description

technical field [0001] The invention belongs to the technical field of dampers, in particular, the invention relates to a damper with adjustable damping. 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 applications. The rotary dam...
