Description

Gaskets for Automotive Engines

The present invention relates to a gasket for an automobile engine, and more particularly, to a gasket for an automotive engine that is intended to improve the airtightness between the cylinder block and the cylinder head.

In general, the vehicle is generated by passing the air cleaner to the gasoline, the main fuel source, inhaling the mixture mixed with the air from which the substance has been removed at a proper ratio into the cylinder through the duct, and then compressing, igniting, and exhausting. The driving wheel is rotated by using the expansion force to enable the driving.

The power generating engine allows the oil pan to store cooling oil to minimize the frictional force of each driving part, and the piston connected to the end of the connecting rod to the top of the oil pan to move up and down. The cylinder block for fixing the crankshaft hinged to the lower end of the rod, the valve device, the head cover, and the intake / exhaust device provided in the upper part of the cylinder block are provided.

Then, a gasket as shown in Figs. 1 to 3 is inserted between the cylinder block and the cylinder head to maintain airtightness.

The gasket 100 is fastened to the first cooling water flow path 160 and the second cooling water flow hole 160a and the first fastening hole 170 at one side of the first hole 150 and the second hole 150a. The upper plate 112 and the lower plate 122 which integrally formed the ball 170a are provided vertically.

A curved first protrusion 110 and a second protrusion 111 are formed outside the first hole 150 of the upper plate 112, and curved outside the second hole 150a of the lower plate 122. The third protrusion 120 and the fourth protrusion 121 are formed.

The ring 130 having the groove 131 formed to the outside of the first hole 150 and the second hole 150a is inserted to prevent the separation thereof.

The first stopper plate 150 is fixed between the first protrusion 110 and the second protrusion 111 of the upper plate 112, and the third protrusion 120 and the fourth protrusion of the lower plate 122 are fixed. It consists of the lower plate 122 for 2nd stoppers in the middle of 121. As shown in FIG.

In the figure, reference numeral 200 is a steel plate, 210 is asbestos, 220 is asbestos coating.

The gasket configured as described above is formed on the first and second protrusions 110 and 111 of the curved shape formed on the upper plate 112 and the lower plate 122 by the load and the clamping force of the self generated during the fastening process. Each protrusion is press-fitted into a space formed in the middle portion between the curved third protrusion 120 and the fourth protrusion 121 to maintain airtightness.

However, there is a problem in that the sealing property is deteriorated due to the phenomenon that the protrusion is easily press-fitted and deformed by the fastening force during the fastening of the gasket.

In addition, there is another problem that the mixer is compressed and leaked to the outside in the process of ignition to contaminate the environment due to the decrease in the sealing property, and thereby the output is reduced.

Therefore, the present invention has been devised to solve such a problem, the automobile is to reinforce the strength to the protrusion formed on the outer side of the hole of the gasket to improve the airtightness to prevent the output from being lowered due to the lowering of the compressive force The purpose is to provide a gasket for this purpose.

The present invention for achieving the above object is an upper plate and a lower plate formed integrally with the first cooling water passage hole and the second cooling water passage hole and the first fastening hole and the second fastening hole in one side of the first hole and the second hole. And a curved first protrusion and a second protrusion are formed outside the first hole of the upper plate, and the curved third protrusion and the fourth protrusion are formed outside the second hole of the lower plate. Inserting a grooved ring outwardly to the inside of the first hole and the second hole to prevent detachment, to fix the plate for the first stopper in the middle of the first projection and the second projection of the upper plate, the third of the lower plate A gasket in which the lower plate for the second stopper is fixed in the middle of the protrusion and the fourth protrusion, the upper elastic body recessed downward in the space between the first protrusion and the fourth protrusion, An upper part fixed to the elastic member is achieved by a gasket for an automobile engine, it characterized in that it comprises a concave bottom elastomers.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

Figure 4 is a cross-sectional view showing the structure of the gasket according to the present invention, Figure 5 is a perspective view of the elastic portion according to the present invention, Figure 6 is a cross-sectional view of the CC line of Figure 5, the same reference numerals for the same configuration as the conventional configuration. do.

In the gasket provided to maintain the airtight by integrally forming each of the protrusions protruding upward and downward to the outside of the hole formed in the upper and lower plates, the present embodiment is to improve the airtightness by reinforcing the strength of the protrusions It is composed.

That is, the upper concave lower elastic body 20 fixed to the bottom of the lower concave upper elastic body 10 is integrally formed to be inserted between the first protrusion 110 and the fourth protrusion 120.

The upper elastic body 10 integrally forms the first support ends 11 and 12 in a circular shape, and the lower elastic body 20 integrally forms the plurality of second support ends 11a and 12a.

The operation of the present invention configured as described above is as follows.

During the process of fastening the cylinder head to the upper portion of the cylinder block, a deforming force acts between the first protrusion 110 and the third protrusion 120, but inside the first support end 11 of the upper elastic body 10. (12) is in close contact with the lower end is supported by the second supporting end (11a) (12a) to prevent the deformation of each projection.

As described above, the present invention prevents the protrusion from being deformed by inserting an elastic body into the space formed in the gasket inserted between the cylinder block and the cylinder head, thereby increasing airtightness and preventing the output from being lowered. It would be.
