Description
Technical field
The utility model relates to engine part field, particularly a kind of cylinder head gasket.
Background technique
Cylinder head gasket is the obturator between the cylinder block and head of I. C. engine, and for meeting its seal request, cylinder head gasket needs to set up enough face pressure values, and face pressure energy enough evenly, continuously.Especially require more and more higher at in-cylinder combustion, it is present that pressure of explosion constantly promotes, if cylinder head gasket provides inappropriate pressure value, is just easy to occur rushing cylinder pad, leaks, the fault such as leakage of oil.The foundation of cylinder head gasket pressure, then connect fastening cylinder block by cylinder head bolt and cylinder head provides, if the local stiffness of connected piece is not enough, local pressure will be caused low.
In existing technological scheme, when considering that pressure provides, often cylinder head and cylinder block being thought of as a rigid objects, thinking that they can Transmit evenly pressure.But in fact because there are many cavitys (process cavity that water channel, air flue and other machinings need) cylinder head and cylinder block inside, cause the rigidity of cylinder block and cylinder head not enough, can not Transmit evenly pressure.So the face pressure value of cylinder head gasket often can not ensure uniformly continous.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Model utility content
The purpose of this utility model is to provide a kind of cylinder head gasket, carrys out complementary area pressure by setting up stiffening plate at regional area, can ensure the face pressure value uniformly continous of cylinder head gasket, improves sealability.
For achieving the above object, the utility model provides a kind of cylinder head gasket, and this cylinder head gasket has the cylinder mouth connection area between adjacent cylinder mouth, and this cylinder head gasket comprises: protective layer, and it comprises top plate and lower plywood; Sealing layer, it is the two-layer corrugated sheet snapped together, and sealing layer is located between top plate and lower plywood; Cylinder mouth guard ring layer, its cross section is U-shaped, and cylinder mouth guard ring layer forms the fringing part of sealing layer at cylinder mouth place; And reinforcement flaggy, it is folded between the two-layer corrugated sheet in cylinder mouth connection area, aligns at cylinder mouth place with sealing layer in the both sides of the edge strengthening flaggy.
Preferably, this cylinder head gasket also comprises adjustment layer, and adjustment layer is folded between two-layer corrugated sheet, and the surface strengthening flaggy and adjustment layer fits together.
Preferably, protective layer, sealing layer and adjustment layer are riveted together by fastener rings.
Compared with prior art, the utility model has following beneficial effect: increased by the position lower in the opposing side pressure of cylinder head gasket between two cylinders and strengthen flaggy, the face pressure at suitable this position of increase, ensures the face pressure value uniformly continous of cylinder head gasket, improves sealability.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figures 1 and 2, according to a kind of cylinder head gasket 10 of the utility model embodiment, this cylinder head gasket 10 has the cylinder mouth connection area S between adjacent cylinder mouth, this cylinder head gasket 10 comprises protective layer, sealing layer, cylinder mouth guard ring layer 4 and reinforcement flaggy 5 (see Fig. 3), particularly, protective layer comprises top plate 11 and lower plywood 12, sealing layer is the two-layer corrugated sheet (21 snapped together, 22), sealing layer is located between top plate 11 and lower plywood 12, the cross section of cylinder mouth guard ring layer 4 is U-shaped, the cylinder mouth edge section of sealing layer is embedded in the U-shaped mouth of cylinder mouth guard ring layer 4, cylinder mouth guard ring layer 4 is made to form the fringing part of sealing layer at cylinder mouth place, strengthening flaggy 5 is folded between the two-layer corrugated sheet in cylinder mouth connection area S, align at cylinder mouth place with sealing layer in the both sides of the edge strengthening flaggy 5, also the shape consistent with the shape of cylinder mouth connection area S (see Fig. 5 and Fig. 1) of flaggy 5 is namely strengthened, the thickness strengthening flaggy 5 is very thin, therefore can the pressure in complemental air cylinder cap and the poor region of cylinder block rigidity provide, the pressure excessively can not sharing other regions can be ensured again.
In addition, this cylinder head gasket 10 also comprises adjustment layer 3, it is folded in two-layer corrugated sheet (21,22) between, and the surface strengthening flaggy 5 and adjustment layer 3 fits together (see Fig. 2), particularly, strengthen flaggy 5 to fit together with the upper surface of adjustment layer 3 or lower surface.
Finally, form the protective layer of this cylinder head gasket 10, sealing layer and adjustment layer and rivet together (see 4) by fastener rings 6.
In such scheme; the protective layer that top plate 11 and lower plywood 12 are formed mainly plays the function of isolation oil, water; two-layer corrugated sheet (21; 22) be functional layer; it is for providing the main sheet material of sealability; adjustment layer 3 mainly plays the thickness difference at adjustment envelope gas position and oil sealing, water position, and cylinder mouth guard ring layer 4 Main Function is for stopping combustion gas impact.When this this cylinder head gasket 10 of riveted, the laminate at riveted position is all designed with location aperture, each sheet material is fixed together (see Fig. 4) through location aperture by fastener rings 6.
To sum up, the cylinder head gasket 10 that the present embodiment provides is by increasing the partial surface pressure of cylinder head gasket, ensure that overall pressure is even, its method is the stiffening plate being increased local by the region (cylinder mouth connection area S) relatively weak in the inner corresponding surface pressure of cylinder head gasket, cylinder pad local is thickeied, the face pressure at suitable this position of increase, solves the problem that cylinder head gasket pressure is uneven and pressure is low because cylinder block and cylinder head local stiffness deficiency cause effectively.
The aforementioned description to concrete exemplary of the present utility model is to illustrate and the object of illustration.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present utility model and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to limited by claims and equivalents thereof.
