Embodiment Construction

[0009] refer to figure 1 , a motorcycle engine cylinder head gasket of the present invention comprises an intermediate steel plate 1, the upper and lower surfaces of the intermediate steel plate 1 are fixed with stamped and formed first and second corrugated metal parts 2, 3, the first, The second corrugated metal parts 2 and 3 are provided with grooves, and the middle steel plate 1 is provided with protrusions. This motorcycle engine cylinder head gasket adopts the above structure, the grooves and protrusions are used for relative positioning, and the corrugated metal parts have the characteristics of good ductility and strong sealing performance. The cylinder head seal formed after being combined with the middle steel plate The anti-deformation ability of the pad is strong, which can effectively avoid the phenomenon that the asbestos rubber pad is easy to be squeezed and contracted to affect the engine compression ratio and valve clearance change, can maintain the consistenc...

Abstract

The invention belongs to the technical field of accessories of motorcycles, and particularly relates to a cylinder end sealing gasket for a motorcycle engine. The cylinder end sealing gasket for the motorcycle engine comprises a middle steel plate. A first wavy metal part and a second wavy metal part which are formed through punching are fixed to the upper surface and the lower surface of the middle steel plate. The first wavy metal part and the second wavy metal part are provided with grooves. The middle steel plate is provided with protrusions. The first wavy metal part and the second wavy metal part are fixedly connected with the middle steel plate through rivets. The cylinder end sealing gasket for the motorcycle engine is good in high-temperature resistance and oil resistance and can completely replace an asbestos rubber pad.

Description

technical field [0001] The invention relates to a motorcycle engine cylinder head gasket. Background technique [0002] Motorcycle engine cylinder head gaskets have relatively high requirements for high temperature resistance and oil resistance. The common motorcycle engine cylinder head gaskets currently on the market generally use asbestos rubber gaskets, non-asbestos rubber gaskets or metal-type fluororubber composite gaskets. However, asbestos materials are highly polluting to the environment, and asbestos dust is easily absorbed by the human body and causes cancer. Therefore, many countries have restricted the use of asbestos-containing gaskets. As a substitute for asbestos rubber gaskets, non-asbestos gaskets lack temperature resistance and oil resistance. Metal-type fluororubber composite gaskets are limited in thickness due to stamping and cutting conditions, and sometimes cannot meet special requirements. Contents of the invention [0003] The technical problem...
