Description
Technical field
This utility model is related to engine cylinder cap field, more particularly to a kind of cylinder head gasket.
Background technology
Cylinder head gasket is the multifunctional spacer being loaded between engine cylinder block and cylinder head.It is a kind of connector, will
Cylinder head is linked together with cylinder block, transmits moment；It is a kind of adjustment part, adjustment compression clearance；It is even more a kind of sealing member, close
Envelope high-temperature high-pressure fuel gas, coolant and lubricating oil.Its quality directly influences quality and the service life of whole electromotor.
At present, some middle low power electromotors adopt compound cylinder head gasket, adopt cylinder mouth guard ring its sealed high-temp high-pressure combustion gas more
The version of cladding asbestos composite metal plate.This structure due to asbestos composite plate make bad, compression ratio is big, resilience
Rate is low, often results in gas sealing power and declines, and rushes cylinder, gas blowby, the quality of impact electromotor.
Utility model content
Based on this it is necessary to provide a kind of preferable cylinder head gasket of sealing effectiveness.
A kind of cylinder head gasket, including pad, described pad is provided with cylinder-bore, and described cylinder-bore periphery is coated with cylinder mouth
Guard ring, the cross sectional shape of described cylinder mouth guard ring is u shape, and described cylinder mouth guard ring is connected with described pad, in described cylinder mouth guard ring and
The arc sealed muscle of outside protuberance, the described arc sealed muscle shape of both sides are respectively equipped with the above and below of described pad contact
Identical and upper-lower position is corresponding；The inner side of described cylinder mouth guard ring is provided with becket.
Wherein in an embodiment, described pad is made up of fibrous material.
Wherein in an embodiment, described becket is made up of hard metal.
Above-mentioned cylinder head gasket, novel in design, rational in infrastructure, dependable performance, good sealing effect, make lining life long,
Favorable environment is protected, and drastically increases reliability and the durability of electromotor.
Brief description
Fig. 1 is the structural representation of cylinder head gasket of the present utility model；
Fig. 2 is a-a sectional view in Fig. 1；
In figure, 1- pad, 2- cylinder-bore, 3- cylinder mouth guard ring, 31- arc sealed muscle, 4- becket.
Specific embodiment
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus make apparent clear and definite to protection domain of the present utility model
Define.
Refer to Fig. 1～2, a kind of cylinder head gasket, including pad 1, pad is provided with cylinder-bore 2, cylinder-bore 2 periphery bag
It is covered with cylinder mouth guard ring 3, the cross sectional shape of cylinder mouth guard ring 3 is u shape, and cylinder mouth guard ring 3 is connected with pad 1, in cylinder mouth guard ring 3 and pad
The arc sealed muscle 31 of outside protuberance is respectively equipped with the above and below of 1 contact, arc sealed muscle 31 shape of both sides identical and on
Lower position is corresponding；The inner side of cylinder mouth guard ring 3 is provided with becket 4.Because this arc sealed muscle 31 has high intensity and high resilience,
In the presence of cylinder bolt thrust, cylinder mouth guard ring 3 is compressed, and the potential energy of arc sealed muscle 31 has just been stored, once
Gas sealing power declines, arc sealed muscle 31 will resilience, the potential energy of storage discharges the reliability it is ensured that gas sealing immediately
Persistently, it is located at the becket 4 in cylinder mouth guard ring 3, metal strong sealing structure can be formed.
Wherein, pad 1 is made up of fibrous material.Becket 4 makes (as steel etc.) by hard metal.
Above-mentioned cylinder head gasket, novel in design, rational in infrastructure, dependable performance, good sealing effect, make lining life long,
Favorable environment is protected, and drastically increases reliability and the durability of electromotor.
Embodiment described above only have expressed several embodiments of the present utility model, and its description is more concrete and detailed,
But therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that it is common for this area
For technical staff, without departing from the concept of the premise utility, some deformation can also be made and improve, these all belong to
In protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be defined by claims.
Claims (3)
