Embodiment Construction

[0025] Such as Figure 1-2 As shown, a sealing gasket for a motor vehicle includes a metal gasket 1 with a circular hole in the middle of the metal gasket 1 and a coating layer 2 on the outer surface of the metal gasket 1 . The coating layer 2 is a rubber coating layer 2, and the rubber coating layer 2 is a rubber composite material wrapped with tetrafluoroethylene. On the rubber coating layer 2 on the front and back of the metal gasket 1, the thickness of the rubber layer gradually changes from thin to thick in the direction from the middle to the periphery. The material of the metal gasket 1 is iron, copper or aluminum. The metal gasket 1 is also provided with several small holes, and the front and back coating layers 2 on the metal gasket 1 are connected together through the small holes. The overall front view of the metal gasket 1 is circular; the overall side view of the metal gasket 1 is arched. The overall side sectional view of the metal gasket 1 is an arc, with low...

Abstract

The invention discloses a sealing gasket for a motor vehicle. The sealing gasket for the motor vehicle comprises a metal gasket, wherein a round hole is formed in the middle of the metal gasket; a coating layer is arranged on the outer surface of the metal gasket; the coating layer is a rubber coating layer; the rubber coating layer is made of a tetrafluoroethylene wrapped rubber composite material; the rubber coating layer on the front side and the back side of the metal gasket is thickened gradually from middle to four sides; and the metal gasket is made of iron, copper or aluminum. The surface of the copper or aluminum gasket is coated with rubber, so that the local deformability of the surface of the gasket is improved, two sealing combined surfaces are in sealing fit well, the sealing effect of the gasket is improved, and untight seal phenomena such as leakage and seepage are reduced. The service life of the sealing gasket is effectively prolonged. The resilience value of the gasket is effectively guaranteed. The local deformability of the gasket is improved. The sealing gasket for the motor vehicle is safe and reliable, and has high sealing property and long life.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle component manufacturing, and in particular relates to a motor vehicle sealing gasket. Background technique [0002] At present, in the technical field of gasket manufacturing for motor vehicle parts, gaskets are a kind of sealing spare parts used for fluid passages such as machinery, equipment, and pipelines. They are used internally and externally to seal equipment and pipelines. Sealing gaskets are made of metal or non-metallic plate materials through cutting, stamping or cutting processes, and are used for the sealing connection between pipes and the sealing connection between parts of machinery and equipment. According to the material, it can be divided into metal sealing gasket and non-metallic sealing gasket. Metal gaskets include copper gaskets, stainless steel gaskets, iron gaskets, aluminum gaskets, etc. [0003] Sealing gaskets in the prior art are usually made of sheet materials...
