Abstract
The utility model discloses a piston ring, especially an automobile shock absorber ware piston ring, including the ring body, characterized by the ring body include the steel backing layer, compound copper base and compound polytetrafluoroethylene layer on copper base's surface on the surface on steel backing layer. The technical problem that it had solved " automobile shock absorber ware piston ring possesses the self -lubricating property, simultaneously low, heat conductivity of coefficient of friction and coefficient of expansion advantage such as little ", the concrete back of using in automobile shock absorber ware piston assembly can promote the stability in use of automobile shock absorber ware piston assembly, prolongs its life simultaneously.
Description
Technical field
The utility model relates to a kind of piston ring, particularly a kind of auto absorber piston ring.
Background technique
Piston ring is one of key components and parts of auto absorber piston assembly, and the quality of piston ring performance characteristic directly affects the performance of automobile absorber.Its major function is sealing, heat conduction, be uniformly distributed lubricant oil and support piston.Piston ring does reciprocating action in company with piston in cylinder body, and be one of worst parts of operating conditions in automobile absorber, its life-span is the shortest.Feature is, operating temperature high and under very high mechanical floats high-speed slide, suffer strong wear.The performance improving piston ring is the key of relation automobile absorber service behaviour.
Hard chromium plating on the working surface of piston ring, although can improve surface hardness and wear resistance, piston ring is led slowly in cylinder sleeve, easy to wear, the cloth uneven defect of oil or technical problem urgently to be resolved hurrily.
Model utility content
The purpose of this utility model provides one to possess self-lubricating property to solve above-mentioned the deficiencies in the prior art, simultaneously low, the thermal conductivity of friction factor and the little auto absorber piston ring of expansion coefficient.
To achieve these goals, a kind of auto absorber piston ring designed by the utility model, comprise ring body, described ring body comprises steel back layer, the polytetrafluoroethylene floor being compounded in the base copper on the outer surface of steel back layer and being compounded on the outer surface of base copper.
Above-mentioned middle provided a kind of auto absorber piston ring, the polytetrafluoroethylmaterial material on its ring body top layer has the performances such as extremely low friction factor, good selflubricating and " anti-creep ", damping and anti-corruption; Base copper as mesosphere and steel back layer as backing layer then provide relatively high bearing capacity, thermal conductivity and expansion coefficient little.Therefore, the piston ring of above-mentioned lamination layer structure after concrete use, effectively can promote stability in use and the efficient work of auto absorber piston assembly in the piston assembly of automobile absorber.
As further technological selection, above-mentioned ring body is also provided with opening.
Described auto absorber piston ring in this preferred version can do suitable adjustment according to the specification of piston in auto absorber piston assembly.
A kind of auto absorber piston ring that the utility model obtains, it has possessed self-lubricating property, simultaneously low, the thermal conductivity of friction factor and some row advantages such as expansion coefficient is little, in auto absorber piston assembly after concrete use, the stability in use of auto absorber piston assembly can be promoted, extend its working life simultaneously.
Accompanying drawing explanation
Fig. 1 be embodiment 1 a kind of structural representation of auto absorber piston ring is provided;
Fig. 2 is the close-up schematic view at A place in Fig. 1:
Fig. 3 be embodiment 2 a kind of structural representation of auto absorber piston ring is provided.
In figure: ring body 1, steel back layer 2, base copper 3, polytetrafluoroethylene floor 4, opening 5.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment 1:
As depicted in figs. 1 and 2, a kind of auto absorber piston ring provided in the present embodiment, comprise ring body 1, described ring body 1 comprises steel back layer 2, the polytetrafluoroethylene floor 4 being compounded in the base copper 3 on the outer surface of steel back layer 2 and being compounded on the outer surface of base copper 3.
Above-mentioned middle provided a kind of auto absorber piston ring, the polytetrafluoroethylmaterial material on its ring body 1 top layer has the performances such as extremely low friction factor, good selflubricating and " anti-creep ", damping and anti-corruption; Base copper 3 as mesosphere then provides relatively high bearing capacity, relatively low thermal conductivity and expansion coefficient with the steel back layer 2 as backing layer.Therefore, the piston ring of above-mentioned lamination layer structure after concrete use, effectively can promote stability in use and the efficient work of auto absorber piston assembly in the piston assembly of automobile absorber.
Embodiment 2: a kind of auto absorber piston ring provided in the present embodiment, and its general structure is consistent with embodiment 1, as shown in Figure 3, but the ring body described in the present embodiment 1 is also provided with opening 5.
A kind of auto absorber piston ring provided in the present embodiment can do suitable adjustment according to the specification of piston in auto absorber piston assembly.
Claims (2)
1. an auto absorber piston ring, comprise ring body (1), it is characterized in that described ring body (1) comprises steel back layer (2), the polytetrafluoroethylene floor (4) being compounded in the base copper (3) on the outer surface of steel back layer (2) and being compounded on the outer surface of base copper (3).
2. a kind of auto absorber piston ring according to claim 1, is characterized in that above-mentioned ring body (1) is provided with opening (5).
