Embodiment Construction

[0022] The sealing structure of the preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] According to the present invention, the sealing structure for sealing multi-joint surfaces is mainly composed of a three-layer structure, the metal layer in the middle provides rigidity for the sealing structure, and the two-layer rubber composite material layer is assembled between the multi-joint surfaces when the force is applied. Microscopic unevenness of the joint surface can be filled. The sealing structure of the invention is especially suitable for the multi-joint surface sealing in the box body of the automobile power assembly. On the one hand, it can ensure the sealing effect, on the other hand, it will not adversely affect the cleanliness inside the powertrain.

Abstract

The invention relates to a sealing structure for sealing a plurality of combination surfaces. The sealing structure comprises a metal layer with opposite first surface and second surface, and a first rubber material layer and a second rubber material layer which are combined onto the first surface and the second surface respectively, wherein a recession facing the butt-welded side seam of the plurality of combination surfaces is formed at a position corresponding to the butt-welded side seam, of the sealing structure; and a bulge rib bulging in a manner of departing from the other surface is formed on the other surface opposite to the surface formed with the recession. The invention further relates to a method for manufacturing the sealing structure, and a method for sealing a box body with a plurality of combination surfaces by virtue of the sealing structure.

Description

technical field [0001] The application belongs to the field of multi-joint surface sealing, and in particular relates to a sealing structure for a multi-joint surface box of a vehicle power assembly. Background technique [0002] At present, the seal of multiple joint surfaces in the vehicle powertrain box is mostly sealed by glue coating. There are certain problems in the traditional way of applying sealant, such as difficult control of the glue application process, low sealing reliability, and easy to affect internal cleanliness, etc. Therefore, for occasions that require high sealing reliability, cleanliness and production cycle, Such as automatic transmission, etc., applying sealant is not the best sealing method. [0003] Metal gasket sealing is another traditional sealing method. However, because there are often height differences at the positions of multiple joint surfaces, it is easy to cause shear deformation and breakage of the sealing structure, thereby making th...
