Abstract
The utility model discloses a piston structure of a shock absorber, which comprises a piston rod, a high-speed throttle valve plate, a bushing piston and an adjusting nut. The piston rod consists of a first piston rod and a second piston rod with different diameter; the lower end of the second piston rod is threaded and is provided with the adjusting nut; a piston nut is arranged at the middle position outside the piston rod; the piston nut is integrated with the bushing piston; a piston ring is arranged at one side of the bushing piston; and the piston nut can drive the bushing piston to rotate up and down for adjusting. The piston structure of the shock absorber has the advantages of rational design, good stability, economic material, large oil pressure bearing, no easy loosening and better integration.
Description
Technical field
The utility model relates to a kind of piston, particularly be a kind of shock absorber piston structure.
Background technique
Present auto absorber piston complex structure, be not easy to machine shaping, in order to bear bigger oil shock, material therefor need be selected the high withstand voltage and high impact material of price for use, thereby cost an arm and a leg, in a single day and make moulding, the pressure that is born is also just fixing, can't regulate vibration damper according to the automobile of different load-carryings, and China also is not fit to the big damping shock absorption device and the air suspension vibration damper of national conditions
The model utility content
The utility model has overcome above-mentioned shortcoming, and a kind of shock absorber piston structure is provided, have simple in structure, be processed into and mould fast, material therefor economy, can bear big oil pressure, and can adjust stressed characteristics.
To achieve these goals, the utility model is to realize by the following technical solutions:
A kind of shock absorber piston structure, it comprises piston rod, high speed restrictions valve block, lining piston and adjusts nut, it is characterized in that, described piston rod is made up of for two sections diameter different the first piston bar and second piston rod, the lower end of described second piston rod is shape of threads and the adjustment nut is installed, in neutral position, the described piston rod outside piston unt is installed, described piston unt and described lining piston are one, the arranged outside of described lining piston has piston ring, and described piston unt can drive the lining piston and rotates up and down and regulate; The upper end of described lining piston is provided with two throttling grooves, be separately installed with check valve sheet on the top of described throttling groove, side at described piston unt is equipped with valve body, O type circle is installed between described valve body and the piston unt, be provided with unidirectional valve block down in the upper end of described O type circle, when shaking along with the variation repeatedly of fluid between the check valve sheet up and down, piston rod can not become flexible yet.
Become flexible for each parts that prevents to install on the shock absorber piston produce, the upper end of described piston rod is equipped with bearing pad and star compression spring successively, makes the shock absorber piston structure more firm in the course of the work.
The utlity model has that reasonable in design, structure steadiness are good, material therefor economy, can bear big oil pressure be difficult for loosening, integrality is better.
