Abstract

The utility model discloses a kind of joint bearing type damper, including frame connecting seat, the first contiguous block is fixedly welded with below the frame connecting seat, the first limited block is equipped with below first contiguous block, damping damper rod is equipped with below first limited block, the outer wall of the damping damper rod is socketed with damping spring, the lower end of the damping damper rod is equipped with the second limited block, the second contiguous block is fixedly welded with below second limited block, vehicle bridge connecting seat is fixedly welded with below second contiguous block.This joint bearing type damper, wear-resisting property is good, good damping effect, when vehicle bridge connecting seat is hit be subject to external force, piston rod is acted on inside piston cylinder be subject to smaller air pressure, after buffer spring is compressed, so as to carry out damping to less vibration amplitude, when making vibration amplitude larger, piston rod continues compressed air, so as to carrying out damping by a relatively large margin.

Description

A kind of joint bearing type damper

Technical field

Damper technical field is the utility model is related to, is specially a kind of joint bearing type damper.

Background technology

The slide cylinder type suspension structure that Hyundai Motor generally uses, collection spring function, damping function, support function and guiding work( The four big functions such as energy are in one.Since its is simple in structure, manufacture alignment error is small and becomes the principal mode of current automotive suspension. As the main damping element of suspension system, damper has vehicle stability very important influence.

Utility model content

The purpose of this utility model is to provide a kind of joint bearing type damper, to solve to propose in above-mentioned background technology The problem of.

To achieve the above object, the utility model provides following technical solution：A kind of joint bearing type damper, including car Frame connecting seat, the frame connecting seat lower section are fixedly welded with the first contiguous block, the first limit are equipped with below first contiguous block Position block, the first limited block lower section are equipped with damping damper rod, and the outer wall of the damping damper rod is socketed with damping spring, described The lower end of damping damper rod is equipped with the second limited block, and the second contiguous block is fixedly welded with below second limited block, described Vehicle bridge connecting seat is fixedly welded with below second contiguous block.

Preferably, the damping damper rod includes piston cylinder and piston rod, and piston rod is located inside piston cylinder.

Preferably, the piston cylinder inner upper end is equipped with buffer spring, and is equipped with cushion pad below buffer spring.

Preferably, cavity is equipped with inside the left and right sidewall of the piston cylinder upper end, the left side cavity inside is equipped with exhaust Pipe, and the inner wall of the lower end connection piston cylinder of exhaust pipe, cavity inside described in right end are equipped with air inlet pipe, and the lower end of air inlet pipe Connect the inner wall of piston cylinder.

Preferably, the exhaust pipe upper end is provided with the first valve, and the upper end of the air inlet pipe is provided with the second valve.

Compared with prior art, the beneficial effects of the utility model are：This joint bearing type damper, wear-resisting property is good, Good damping effect, when vehicle bridge connecting seat is hit be subject to external force, piston rod is acted on inside piston cylinder be subject to smaller air pressure, After buffer spring is compressed, so as to less vibration amplitude carry out damping, when making vibration amplitude larger, piston rod after Continuous compressed air, so as to carrying out damping by a relatively large margin.
