Abstract
The invention belongs to technical field of automobile parts, more particularly to a kind of car combustion engine piston ring.Car combustion engine piston ring includes ring body, and the ring body surface is covered with anticorrosive coat, and described ring body one end is provided with sealing flange, and the other end is provided with the connector being used cooperatively with the sealing flange；Set fluted on the connector, the male member being used cooperatively with the groove is provided with the sealing flange；The side of the connector is provided with connecting hole, and the side of the sealing flange is provided with the bulge-structure being used cooperatively with the connecting hole；Sealing gasket is provided with the connector outer ledge.Therefore the present invention solves the problems, such as that poor sealing performance and service life are short in above-mentioned background technology.
Description
Technical field
The invention belongs to technical field of automobile parts, more particularly to a kind of car combustion engine piston ring.
Background technology
Piston ring is the core component on cylinder of internal-combustion engine, and the piston ring used at present on cylinder of internal-combustion engine is in becket
On be provided with a collar extension, its collar extension gap is between 0.5-0.7mm, and in use due to being worn, collar extension gap gradually increases
Greatly, the air leakage in cylinder is consequently increased, and causes diesel locomotive power drop, and fuel consumption increase, burn oil, smoke evacuation mist is big,
Air is polluted, even causes machine to use.Therefore piston ring still suffers from use can not reach prolonged good close
Envelope, the problem of service life is short.
The content of the invention
The present invention provides a kind of car combustion engine piston ring, to solve in above-mentioned background technology poor sealing performance and using the longevity
Order the problem of short.
Car combustion engine piston ring provided by the invention, including ring body, the ring body surface are covered with anticorrosive coat, the ring body
One end is provided with sealing flange, and the other end is provided with the connector being used cooperatively with the sealing flange；
Set fluted on the connector, the convex being used cooperatively with the groove is provided with the sealing flange
Part；
The side of the connector is provided with connecting hole, and the side of the sealing flange is provided with to be coordinated with the connecting hole
The bulge-structure used；
Sealing gasket is provided with the connector outer ledge.
Further, the inside grooves are provided with blind hole, and the male member bottom is provided with to be adapted with the blind hole
Connecting pin.
Further, the inwall of the connecting hole is rough surface.
Relative to prior art, car combustion engine piston ring provided by the invention has following advantage：
Car combustion engine piston ring provided by the invention, because ring body surface is covered with anticorrosive coat, and ring body one end is provided with
Sealing flange, the other end are provided with the connector being used cooperatively with sealing flange；Set on connector it is fluted, on sealing flange
It is provided with the male member being used cooperatively with groove；The side of connector is provided with connecting hole, the side of sealing flange be provided with
The bulge-structure that connecting hole is used cooperatively；So can improve ring body obtains sealing property, prevent gas from leaking, reduce oil consumption, together
When can improve its antiwear property.
In addition, inside grooves are provided with blind hole, male member bottom is provided with the connecting pin being adapted with blind hole, can more enter
The sealing property of the raising ring body of one step.
Brief description of the drawings
, below will be to specific in order to illustrate more clearly of the specific embodiment of the invention or technical scheme of the prior art
The required accompanying drawing used is briefly described in embodiment or description of the prior art, it should be apparent that, in describing below

Embodiment
Technical scheme is clearly and completely described below in conjunction with accompanying drawing, it is clear that described implementation
Example is part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill
The every other embodiment that personnel are obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
As shown in figure 1, the car combustion engine piston ring that the present embodiment provides, including ring body 1, the surface of ring body 1 are covered with anti-corrosion
Layer, the one end of ring body 1 are provided with sealing flange 5, and the other end is provided with the connector 2 being used cooperatively with sealing flange 5；Connector 2
It is upper to set fluted 3, it is provided with the male member being used cooperatively with groove 3 on sealing flange 5；The side of connector 2 is provided with company
Hole 4 is connect, the side of sealing flange 5 is provided with the bulge-structure 6 being used cooperatively with connecting hole 4；Set at the outer ledge of connector 2
There is sealing gasket；Ring body 1 can be improved and obtain sealing property, prevent gas from leaking, reduce oil consumption, while its wear-resistant energy can be improved
Power.
Preferably, groove 3 is internally provided with blind hole, and male member bottom is provided with the connecting pin being adapted with blind hole；Can
The further sealing property for improving ring body 1.
Preferably, the inwall of connecting hole 4 is rough surface, it is possible to increase the sealing between connecting hole 4 and bulge-structure 6
Energy.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
The present invention is described in detail with reference to foregoing embodiments for pipe, it will be understood by those within the art that：Its according to
The technical scheme described in foregoing embodiments can so be modified, either which part or all technical characteristic are entered
Row equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the present invention technology
The scope of scheme.
