Technical field
The utility model relates to a kind of engine sealing, specifically a kind of cylinder gasket comprising cylinder choma structure.
Background technique
Cylinder gasket is mounted in the sealed member between cylinder head and cylinder block, its role is to reliable sealing high-temperature fuel gas, lubricant oil and cooling liquid, prevents from revealing, and the quality of cylinder gasket directly affects the performance of motor.
Along with the continuous lifting of engine performance, the pressure of explosion of motor is also more and more higher, but limit by body, cylinder head material intensity, bolt axial force can not correspondingly increase, therefore need cylinder gasket to meet motor seal request under relatively low bolt axial force, to the distortion of engine cylinder port part, there is higher compensation ability simultaneously.At present, common motor cylinder gasket is as figure
1shown in, what the cylinder-bore edge of conventional laminated metal cylinder gasket was formed is bag degree of lip-rounding formula, and this kind of structure is relatively low to the deformation-compensated ability of cylinder port part.Found a kind of structure simple, good seal performance, the new cylinder gasket that comprise cylinder choma structure high to the deformation-compensated ability of cylinder port part, tool is of great significance.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of cylinder gasket comprising cylinder choma structure, when engine operating condition rather harsh, as: detonation pressure improves, the distortion of cylinder mouth aggravates, and effectively can guarantee gas seal, profit hole sealing reliability can be made again to get a promotion.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of cylinder gasket comprising cylinder choma structure, comprise shim body, cylinder choma and rubber ring, described shim body is provided with at least one cylinder-bore and multiple profit hole, bolt hole and positioning hole, shim body comprises upper plate, middle plate and lower plate three-layer metal thin plate, every layer of sheet metal is hatch frame in the position at described cylinder-bore edge, described cylinder choma is located at around cylinder-bore, described rubber ring is located at around profit hole, described cylinder choma and rubber ring are all fixedly connected with the middle plate of shim body.
Improve as one of the present utility model, the thickness of described cylinder choma is greater than middle plate, and the two forms section difference structure, and described cylinder choma and the link position of middle plate are no less than two places.
Further, the upper plate of shim body and the position of lower plate respective cylinder choma are suppressed with gas seal ripple.
Further, described upper plate becomes symmetric relation with the gas seal ripple of lower plate.
Further, described cylinder choma is connected on the middle plate of shim body by riveted joint or spot welding, and described rubber ring is riveted by metal frame or put and is welded on middle plate.
Further, the direct sulfuration of described rubber ring is in shim body on plate.
Further, link together by connecting guard ring between the upper plate of described shim body, middle plate and lower plate.
Further, be fixedly connected with by riveted joint or spot welding between the upper plate of described shim body, middle plate and lower plate.
The beneficial effects of the utility model are:
1. plate slightly thick formation section difference structure in cylinder choma ratio described in, play the effect of cylinder mouth envelope gas, described pad upper and lower plates respective cylinder choma position is suppressed with gas seal ripple, coordinates and plays auxiliary function of sealing gas, improve reliability and the durability of cylinder gasket gas seal with cylinder choma.
2. rubber ring described in is by skeleton and middle plate riveting, and position is fixing mistake can not occur partially, improves the reliability of profit sealing.
3, cylinder gasket of the present utility model improves gas, oil, the water-stop effect of cylinder gasket, improve cylinder gasket gas, oil, the reliability of water-stop and durability simultaneously, can effectively improve pad deformation-compensated to cylinder port part, structure is simple, easy to use, long service life, good sealing effect.
