Abstract
The utility model discloses an anti-leakage cylinder gasket with rubber ring, comprising a cylinder gasket body, wherein a cylinder opening, a location hole, a bolt hole, a cooling liquid hole and a lubricant hole are formed in the cylinder gasket body; a rubber ring is disposed in the lubricant hole and the cooling liquid hole respectively; a plurality of rings of annular sealing bulges is disposed on the two end surfaces of the rubber ring respectively. The cylinder gasket has the advantages of that: because a plurality of rings of annular sealing bulges is disposed on the two end surfaces of the rubber ring respectively, the rubber ring changes the whole compression stress of the traditional rubber ring while compressing and concentrates a sealing force on the a plurality of rings of annular sealing bulges, thereby increasing the reliability to a lubricant and cooling liquid seal in an engine by the rubber ring; the sealing performance is good; oil leakage and water leakage can be avoided; the whole performance of the engine can be improved.
Description
Technical field
The utility model relates to a kind of rubber ring structure engine head gasket, particularly a kind of leakage proof rubber ring head gasket.
Background technique
Continuous development along with engine technology, the pressure of explosion of motor is further promoted, but be confined to the self reason of bolt and cylinder block, cylinder head material, the bolt torque of locking cylinder lid can not well improve with the lifting of pressure of explosion in the lump, this just requires the head gasket must be under relatively low bolt tightening torque, more in the past than the sealing of more effectively finishing high temperature and high pressure gas, lubricant oil and cooling liquid.Rubber ring structure head gasket occurs under this condition.Existing rubber ring structure head gasket is provided with cylinder port, positioning hole, bolt hole, cooling liquid hole and oilhole on the head gasket body, stud with rubber ring in cooling liquid hole and oilhole respectively.Traditional rubber ring profile is relatively near O type circle, and section is generally circular or square.This structure has well solved the design challenges of the high pressure of explosion of low bolt torque, but the poor stability of this sealing structure, occurs the fault of oil impregnate, infiltration easily, has influenced the overall performance of motor.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of good seal performance, can avoid occurring oil impregnate, infiltration, can improve the leakage proof rubber ring head gasket of motor overall performance.
The leakage proof rubber ring head gasket that the utility model is related, comprise the head gasket body, on the cylinder liner body, be provided with cylinder port, positioning hole, bolt hole, cooling liquid hole and oilhole are respectively equipped with rubber ring in oilhole and cooling liquid hole, its special way is: be respectively equipped with the multi-ring annular seal convexity on two end faces of rubber ring.
Above-mentioned leakage proof rubber ring head gasket, described ring packing projection is the 2-3 circle.
The utility model has the advantages that: owing on two end faces of rubber ring, be respectively equipped with the multi-ring annular seal convexity, therefore when compression rubber ring to have changed traditional rubber ring reduced overall stressed, but sealing force is focused on the multi-ring annular seal convexity, thereby improved the reliability of rubber ring to lubricant oil in the motor and cooling liquid sealing, good seal performance, oil impregnate, infiltration can be avoided occurring, the motor overall performance can be improved.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view Amplified image (corresponding embodiment 1) of Fig. 1;
Fig. 3 is the A-A cutaway view Amplified image (corresponding embodiment 2) of Fig. 1.
Among the figure: head gasket body 1,101, two positioning holes 102 of cylinder port, bolt hole 103, cooling liquid hole 104, oilhole 105, rubber ring 2, ring packing projection 201.
Embodiment
As depicted in figs. 1 and 2, this leakage proof rubber ring cylinder is lined with a head gasket body 1 that adopts metallic material to make, on head gasket body 1, be provided with a cylinder port 101, two positioning holes 102, four bolts hole 103 and a plurality of cooling liquids hole 104 and oilholes 105, in cooling liquid hole 104 and oilhole 105, stud with rubber ring 2 respectively, on upper and lower two end faces of rubber ring 2, be respectively equipped with multi-ring annular seal convexity 201, ring packing projection 201 is preferably the 2-3 circle, and present embodiment is an example with 2 circles.
After head gasket installed, rubber ring 2 launched machine cylinder bodies and cylinder cap compression owing to be provided with ring packing projection 201 on the rubber ring 2, made sealing load concentrate on the 2 circle ring packing projectioies 201, can reach the purpose of sealing cooling liquid and lubricant oil.
As shown in figures 1 and 3, be respectively equipped with multi-ring annular seal convexity 201 on upper and lower two end faces of rubber ring 2, present embodiment ring packing projection is an example with 3 circles.Other is with embodiment 1.
Claims (2)
1. leakage proof rubber ring head gasket, comprise the head gasket body, on the cylinder liner body, be provided with cylinder port, positioning hole, bolt hole, cooling liquid hole and oilhole are respectively equipped with rubber ring in oilhole and cooling liquid hole, it is characterized in that: be respectively equipped with the multi-ring annular seal convexity on two end faces of rubber ring.
2. leakage proof rubber ring head gasket according to claim 1 is characterized in that: described ring packing projection is the 2-3 circle.
