Description
Technical Field
The utility model relates to an automobile engine seals technical field, especially relates to an automobile engine cylinder head cover is sealed to be filled up.
Background
A cylinder head cover sealing gasket is arranged between a cylinder head and a cylinder head cover of an automobile engine, and the purpose is to enhance the sealing property between the cylinder head and the cylinder head cover so as to prevent lubricating oil in the cylinder head and the cylinder head cover from leaking. At present, most of engine cylinder head cover sealing gaskets adopt a plane sealing mode, namely, the contact surfaces of the engine cylinder head cover sealing gaskets and a cylinder head cover are in plane contact, the contact surfaces of the engine cylinder head cover sealing gaskets and the cylinder head cover are also in plane contact, a sealing groove is designed on the engine cylinder head cover, and a raised strip matched with the sealing groove is arranged on the engine cylinder head cover sealing gaskets so as to increase the sealing property and overcome the unstable factors of plane sealing. However, most of the existing sealing gaskets are of single-layer rubber structures, when the sealing gaskets are used, the sealing gaskets can be extruded by a cylinder cover and a cylinder cover, the sealing gaskets can be damaged under the extrusion effect, and lubricating oil leakage occurs at part of sealing positions, so that the sealing gaskets of the cylinder cover of the automobile engine are designed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving and having among the prior art that cylinder cap and cylinder head cover extrusion seal pad cause sealed the pad to damage, lead to the shortcoming that lubricating oil revealed, and the sealed pad of automobile engine cylinder head cover that proposes.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a sealed pad of automobile engine cylinder head cover, includes the linen layer, the both sides fixed hot melt on linen layer is connected with soft rubber layer, the fixed hot melt in the outside on soft rubber layer is connected with hard rubber layer, the fixed hot melt in the outside on hard rubber layer is connected with sealing rubber layer, sealing rubber layer's the outside is provided with the arcuation arch, three and ring phase cover are no less than to the bellied quantity of arcuation, be the integrated into one piece structure between the arcuation arch and the sealing rubber layer, one of them the fixed adhesion in edge on sealing rubber layer has thin rubber frame.
Preferably, the soft rubber layer is vulcanized rubber.
Preferably, the hard rubber layer is made of polyurethane rubber.
Preferably, the sealing rubber layer is made of silicon rubber.
Preferably, the thickness ratio of the linen layer, the soft rubber layer, the hard rubber layer and the sealing rubber layer is 1:2:1: 2.
The utility model provides a pair of automobile engine cylinder head cover is sealed to be filled up, beneficial effect lies in: the gasket of the cylinder head cover of the automobile engine greatly improves the pulling resistance of the gasket by arranging the linen layer as a substrate at the innermost part of the gasket, in addition, the outer side of the linen layer is sequentially provided with the soft rubber layer, the hard rubber layer and the sealing rubber layer, the soft rubber layer increases the variable quantity of the gasket, the hard rubber layer can balance the pressure, the pressure applied by the cylinder head and the cylinder head cover is completely distributed on the soft rubber layer, the local damage of the gasket caused by the overlarge stress of a single point is avoided, in addition, the arc-shaped convex arrangement on the sealing rubber layer and the sealing rubber layer can increase the sealing degree between the gasket and the cylinder head cover, especially, a plurality of seals are formed between the gasket and the cylinder head cover, the sealing performance of the sealing ring is greatly improved, and the problem that the gasket is damaged due to the extrusion of the cylinder head and the cylinder head cover in the prior art is solved, the lubricating oil leakage is caused, the beneficial effect is obvious, and the lubricating oil leakage prevention device is suitable for popularization.
