Problems solved by technology
However, ordinary sealing structures often lead to leakage under extreme working conditions. The conventional solution is to apply glue multiple times in this area, but it will cause serious waste of glue, and its assembly efficiency is low, product consistency and durability are poor

Embodiment Construction
[0016] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation, structure, features and effects of the present invention will be described in detail below in conjunction with the accompanying drawings and examples.
[0017] Such as Figure 1-3 As shown, the three joint surface sealing structure of an embodiment of the present invention includes a cylinder head 1 , a cylinder gasket 2 , a cylinder block 3 and a timing chain cover 4 . Cylinder head 1, cylinder head gasket 2, cylinder block 3 and timing chain cover 4 are assembled with each other and form a rubber storage tank 5 on the end face, and the rubber storage tank 5 is on the three end faces of cylinder head 1, cylinder block 3 and timing chain cover 4 The width of the junction is greater than the width of the junction of the two end surfaces of the cylinder head 1 and the timing chain cover 4 or the cylinder block ...

The invention provides a sealing structure of three joint surfaces. The sealing structure comprises a cylinder head, a cylinder head gasket, a cylinder block and a timing chain guard which are assembled mutually and enclosed to form a glue storage tank at the end faces; and the width of the glue storage tank at the joint of the three end faces of the cylinder head, the cylinder block and the timing chain guard is larger than the width of the glue storage tank at the joint of two end faces of the cylinder head and the timing chain guard or the cylinder block and the timing chain guard. Since the width of the glue storage tank at the joint of the three end faces of the cylinder head, the cylinder block and the timing chain guard is larger than the width of the glue storage tank at the joint of two end faces of the cylinder head and the timing chain guard or the cylinder block and the timing chain guard, a glue tape formed in this way can constitute a sealing tape with the cylinder head gasket, and the sealing reliability is improved; and at the same time the terminal difference between the cylinder head gasket and the cylinder block and the cylinder head can be tolerated, and the leakage risk is reduced.
Description
technical field [0001] The invention relates to the technical field of automobiles, and in particular to a three-joint surface sealing structure. Background technique [0002] The leakage problem of the three-joint surface has always been a difficult problem faced by various engine products, and the reason is mostly the problem of the design of the three-joint surface sealing structure. [0003] At present, the instant sealing method of coating silica gel is generally used for flat sealing. The principle of silica gel sealing is to use the moisture in the air to cure at room temperature to form an instant sealing strip. In order to absorb the large movement and dislocation of the flange and prevent the internal system from being polluted by the cured rubber block inside the flange, the sealing surface will be designed with a rubber-receiving structure, which is usually in the form of a rectangle and a slope. In general design, the glue tank will adopt uniform size and speci...
