Abstract

The utility model relates to a crisscross opposite buckling piston ring which can prevent the phenomena of opening and opposing opening. The utility model provides the technical proposal that a connector which can be extended through an upper ring surface and a lower ring surface is arranged on the piston ring, and two connector end surfaces of the connector are crossed and connected in the opposite buckling way. Under the condition that the crisscross opposite buckling piston ring has the elasticity permission, an integral and freely adjustable best sealing surface is formed between a piston and a cylinder sleeve, without the opening clearance, the lateral clearance and the back clearance of the ring influencing, a collar extension adopts the design of crossing and opposite buckling, and the opening is filled up mutually, to ensure that the whole ring does not have the phenomena of opening and opposing opening and increase the compression ratio, to ensure that the power of an engine is improved, lasting and permanent, and is provided with the energy saving effect. The utility model is applied to the gas ring and the oil ring.

Description

Intersection make-up piston ring

Technical field

The utility model belongs to the piston ring technical field, especially a kind of intersection make-up piston ring.

Background technique

Piston ring is the extremely vital component of engine interior, plays a seal action between cylinder sleeve and piston, and the quality of its sealability is the service behaviour and the exhaust index of the whole motor of influence directly.Since ancient times, exist piston ring under the situation of flexible permission, opening is progressively encircled with the wearing and tearing of cylinder sleeve and is become big always, cause the motor gas blowby, scurry oily phenomenon, engine power is descended, lowered motor working life, solve the structure that above-mentioned serious problems must be improved ring greatly.

The model utility content

The purpose of this utility model is that a kind of intersection make-up piston ring will be provided, make ring under the situation of flexible permission, can between cylinder sleeve and piston, form one complete, can freely regulated optimal seal face, ring the opening phenomenon can not occur, just not to lip reflex yet.

The technical solution of the utility model is; Intersection make-up piston ring is characterized in that described piston ring is provided with one and runs through the interface of anchor ring up and down, and two interface end hand-deliver fork make-ups of interface connect.

An interface end face is provided with raised land therein, is provided with concave surface accordingly at another interface end face.

Close upper ring surface one side of described raised land be shaped as two step surfaces, the raised land outside is a piston ring outer ring face part; The raised land inboard is a plane, and the bottom of raised land is the part of anchor ring under the piston ring, and raised land is the plane near a side of another interface end face.

Effect of the present utility model is: two interface end hand-deliver fork make-ups of intersection make-up piston interface connect, infall has had support mutually, and ring is not fractureed at work, adopts the monolithic whole design to make ring resilience reach the optimum state, be not stuck, sealing effect improves greatly; " opening ", " counterpart " phenomenon can not appear in piston ring in operating movement, exactly several roads ring infall is placed on same position, can not influence the sealing effect of ring yet.Under the situation of the flexible permission of piston ring, the not frayed influence of sealing effect of ring, make ring between cylinder sleeve and piston, form one complete, can freely regulated sealing surface, greatly improve the working life of ring, solved undesired gas blowby from start to finish, scurried oily phenomenon, reduced exhaust index, engine power is improved.

Below in conjunction with drawings and Examples the utility model is further described.

The drawing explanation

Fig. 1 is the plan view of the utility model embodiment piston ring;

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is an interface end face structural representation.

Embodiment

Among Fig. 1, intersection make-up piston ring, described piston ring are provided with one and run through anchor ring interface 1 up and down, and two interface end faces, 2, the 3 intersection make-ups of interface connect, and the 4th, piston ring inner ring face, the 5th, piston ring outer ring face, the 6th, piston ring upper ring surface.

Among Fig. 2, the 7th, the outer ring face connecting line that interface end face 2,3 intersection make-ups connect, the 5th, piston ring outer ring face, the 6th, piston ring upper ring surface, the 8th, anchor ring under the piston ring.

Among Fig. 3, interface end face 3 is provided with raised land, close piston ring upper ring surface 6 one sides of described raised land be shaped as two

step surfaces

9,10, the raised land outside 11 is the part of piston ring outer ring face 5, raised land inboard 12 is a plane, the bottom 13 of raised land is the part of anchor ring 8 under the piston ring, and raised land is the plane near a side 14 of another interface end face.Be provided with accordingly on another interface end face 2 with interface end face 3 on the corresponding concave surface of raised land.Specifically, interface end face 2 is provided with and step surface 10 corresponding groove 15, the concave surface 16 corresponding with step surface 9, the bottom surface 17 of interface end face is the part of following anchor ring 8, and interface end face 2 is connected with interface end face 3 intersection make-ups, forms a complete piston ring.

Present embodiment is to illustrate of the present utility model with the compression ring piston ring.Compression ring adopts the design of intersection make-up design monolithic to make ring resilience reach the optimum state, and ring is not stuck, and the sealability of ring and cylinder sleeve is greatly enhanced, and has reduced waste gas.Collar extension adopts cross-over design to fill up opening mutually, make do not catch a cold thermal expansion and opening of ring become big influence, the make-up design is adopted in the infall crosscut, strengthened infall two rings strength up and down, because ring makes ring be close to the piston ring groove bottom in the effect of pressurized gas power, makes ring not be subjected to the influence of standard width of a room in an old-style house crack, sideshake, back clearance and has thoroughly solved downward gas-blowing phenomenon.Ring juxtaposition just before installation makes ring " opening ", " counterpart " phenomenon can not occur in operating movement.Infall has had support mutually, and ring is not fractureed at work, encircles the arc design of outer employing garden, has reduced the friction factor of ring and cylinder sleeve, the power of reducing friction.

Structure of the present utility model is equally applicable to oil ring.
