Two-way damper

Abstract

The invention provides a two-way damper. The two-way damper comprises a cylinder body, and further comprises two piston rods arranged at the two ends of the cylinder body correspondingly, elastic diaphragms which are arranged between floating pistons on the two sides and oppositely fixed to the interior of the cylinder body and fixed pistons which are located between the elastic diaphragms on thetwo sides and fixed to the interior of the cylinder body; one end of each piston rod is inserted into the cylinder body through a sealing mechanism in a guiding mode, the inserting end of each pistonrod is provided with the corresponding floating piston sliding in the cylinder body, and each floating piston is provided with a first damping channel communicating with the two sides of the floatingpiston; the elastic diaphragms isolate the portions, on the two sides of the elastic diaphragms, of the space in the cylinder body; a second damping channel communicating with the two sides of the fixed piston is formed in each fixed piston; and the portions, on the two sides of the elastic diaphragms, of the cylinder body are filled with damping liquid. According to the two-way damper, the damperstructure can be simplified, the cost is reduced, and the good practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of dampers, in particular to a bidirectional damper. Background technique [0002] Damper is a device that provides resistance to movement and consumes movement energy. Hydraulic damper is the most widely used type of damper. Because of its sensitivity to speed response, it has been widely used in industrial production facilities, transportation Machinery and other occasions where vibration is required to be buffered. Existing hydraulic dampers generally realize the damping effect by dissipating energy through the damping fluid flowing through the orifice, and by adjusting the size of the orifice aperture, the flow rate of the damping fluid can be changed to achieve the effect of adjusting the damping coefficient of the damper . [0003] In order to avoid the leakage of damping fluid and ensure the normal operation of the hydraulic damper, a complex sealing structure needs to be designed in the structure o...

AI Technical Summary

Problems solved by technology

[0003] In order to avoid the leakage of damping fluid and ensure the normal operation of the hydraulic damper, a complex sealing structure needs to be designed in the structure of the hydraulic damper itself, which will undoubtedly increase the manufacturing cost of the damper. The service life of the sealing structure is generally short, which in turn will bring high maintenance costs.

In addition, due to the relative movement between the piston and the cylinder in the hydraulic damper, it is easy to cause the damping force to be not significantly improved at high speeds, which will also affect the use effect of the damper
