Description

Damper

Technical field

It the utility model is related to damping device, more particularly to a kind of damper.

Background technology

Automotive wheel shifts near vehicle body, and when damper is compressed, now damper inner carrier moves down.Piston lower chambers Volume reducing, oil pressure rise, fluid push the chamber (epicoele) that flow- through valve plate flows to piston upper open.Epicoele is accounted for by piston rod A part of space, thus the increased volume of epicoele is less than the volume that cavity of resorption reduces, a part of fluid then just pushes compression valve block open, Flow back to oil storage cylinder.Saving of these valves to oil forms the damping force of the compressed motion of suspension.Damper, away from vehicle body, subtracts in wheel Device Tensile is shaken, at this moment the piston of damper moves up.Piston upper chamber oil pressure is raised, and flowing valve is closed, the fluid of upper intracavitary Push open and restore valve block inflow cavity of resorption.Due to the presence of piston rod, the fluid come from epicoele stream is not enough to be full of the increased appearance of cavity of resorption Product, instigator's cavity of resorption produce a vacuum, and at this moment the fluid in oil storage cylinder, which pushes compensator valve plate open and flows into cavity of resorption, is supplemented.Due to this The throttling action of a little valves, therefore damping action is played when doing stretching exercise to being suspended in.

The rebuilt valve of existing damper uses spring structure, and Assembly part is more, and assembling is complicated so that damper assembling life It is low to produce efficiency, cost is high
