Abstract
The utility model relates to an engine cylinder pad field, concretely relates to gasoline engine cylinder pad structure, including ripplet seal structure, half -wave sealing rib structure and all -wave sealing rib structure, ripplet seal structure arranges at the bolt hole in jar mouth and cylinder gasket four corners peripherally, and half -wave sealing rib structural arrangement is at water hole and oilhole periphery, all -wave sealing rib structural arrangement cylinder gasket's front and back end, and the packing has fluorine sealing rib 0 between the backing plate. Arrange the riveted structure at cylinder gasket. Ripplet seal structure's upper and lower layer backing plate cross -section is ripplet shape for straight plate -type, middle level backing plate cross -section. The going up of half -wave sealing rib structure in, lower floor backing plate cross -section are trapezoidally. The going up of all -wave sealing rib structure in, lower floor backing plate cross -section are the circular arc. The utility model discloses the last pressure that bears of rational distribution cylinder gasket is realized engine cylinder mouth, the mouth of a river, the high -efficient and reliable of hydraulic fluid port and is sealed, and then reduces cylinder gasket's change number of times, maintains the long -term reliability service of engine.
Description
Technical field
This utility model relates to engine cylinder ring field, is specifically related to a kind of gasoline engine cylinder mat structure.
Background technology
Along with the progressively development of gasoline engine technology, degree of boost and the explosion pressure of gasoline engine continue to increase, and have higher requirement the sealing of head gasket.Existing head gasket major part is applicable to the petrol engine of non pressurized low detonation pressure, is therefore badly in need of designing the head gasket of a kind of high sealing performance high reliability to adapt to the development of technology of gasoline engine.
Utility model content
The purpose of this utility model is to realize above-mentioned requirements, it is provided that a kind of gasoline engine cylinder mat structure.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of gasoline engine cylinder mat structure, structure, half-wave sealed muscle structure and all-wave sealed muscle structure is sealed including ripplet, ripplet seals structure and is arranged in the bolt hole periphery of cylinder mouth and head gasket corner, half-wave sealed muscle structure is arranged in water hole and oilhole periphery, all-wave sealed muscle structure is held before and after arranging head gasket, above-mentioned three kinds of sealing structures all include upper, middle and lower-ranking backing plate, are filled with fluorine rubber coating between backing plate.
Being respectively arranged three riveted structures on the side, inlet, outlet side of head gasket, this riveted structure is that concave structure made by three layers of backing plate.
It is straight plate shape that ripplet seals the upper and lower layer backing plate cross section of structure, and backing plate cross section, middle level is ripplet shape.
The layer backing plate cross section, upper, middle and lower of half-wave sealed muscle structure is trapezoidal.
The layer backing plate cross section, upper, middle and lower of all-wave sealed muscle structure is circular arc.
The beneficial effects of the utility model are: the pressure born on reasonable distribution head gasket, it is achieved engine cylinder mouth, the mouth of a river, the efficient and positive sealing of hydraulic fluid port, and then reduce the replacing number of times of head gasket, maintain the operation reliably and with long-term of electromotor.

Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings:
Embodiment: see Fig. 1 to Fig. 6.
A kind of gasoline engine cylinder mat structure, structure 1, half-wave sealed muscle structure 2 and all-wave sealed muscle structure 3 is sealed including ripplet, ripplet seals structure 1 and is arranged in bolt hole 5 periphery of cylinder mouth 4 and head gasket corner, half-wave sealed muscle structure 2 is arranged in water hole 7 and oilhole 6 periphery, all-wave sealed muscle structure 3 is held before and after arranging head gasket 8, above-mentioned three kinds of sealing structures all include upper, middle and lower-ranking backing plate 10,11,12, are filled with fluorine rubber coating between backing plate.
Being respectively arranged three riveted structures 9 on the side, inlet, outlet side of head gasket 8, this riveted structure 9 is that concave structure made by three layers of backing plate 10,11,12.
It is straight plate shape that ripplet seals upper and lower layer backing plate 10,12 cross section of structure 1, and middle level backing plate 11 cross section is ripplet shape.
Upper, middle and lower layer backing plate 10,11,12 cross section of half-wave sealed muscle structure 2 is trapezoidal.
Upper, middle and lower layer backing plate 10,11,12 cross section of all-wave sealed muscle structure 3 is circular arc.
The beneficial effects of the utility model are: the pressure born on reasonable distribution head gasket, it is achieved engine cylinder mouth, the mouth of a river, the efficient and positive sealing of hydraulic fluid port, and then reduce the replacing number of times of head gasket, maintain the operation reliably and with long-term of electromotor.
What embodiment of the present utility model was announced is preferred embodiment; but it is not limited thereto; those of ordinary skill in the art; easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and change, but as long as without departing from spirit of the present utility model, all in protection domain of the present utility model.
