Background
At present, in an internal combustion engine, the operating conditions of a cylinder head are severe, and the cylinder head is subjected to the high temperature and high pressure generated by combustion gas. Most of the existing motorcycles adopt four cylinders, the power of the four cylinders is sufficient, but the displacement is too large. The current policy places restrictions on the weight and displacement of the motorcycle, which requires the manufacturing enterprise to make adjustments accordingly, and adjusting the product involves replacing all the machining dies for all the parts, which is a considerable burden for the enterprise. The components of a four-cylinder machine are selected as much as possible in the industry at present, the matching size and the interfaces of the components and other components are unchanged, and the internal pipeline is redesigned, so that partial problems are solved, however, because the four cylinders are adopted, the combustion chamber, the air inlet and exhaust passages are kept unchanged, the matching size of the components and valve mechanisms such as a rocker arm shaft, a cam shaft and an air valve is unchanged, the front end structure is kept unchanged, a water passage and an oil passage are redesigned, a rear end cover is omitted, a junction temperature device, a cover and a water pipe are arranged at the rear end of the cylinder cover in an extending mode, the installation of a cam shaft thrust sheet on a third cam bearing seat is changed, the interfaces of parts and the outside are rearranged, and the overall design requirements are met. However, the existing motorcycle cylinder head cover shell is composed of a plurality of structures, so that the weight of the whole structure is increased; meanwhile, the spark plug mounting hole and the mounting connecting hole on the shell of the existing motorcycle cylinder head cover are arranged, so that the strength of the whole structure is reduced.
Through the above analysis, the problems and defects of the prior art are as follows:
(1) the existing motorcycle cylinder head cover shell is composed of a plurality of structures, and the weight of the whole structure is increased.
(2) The spark plug mounting hole and the mounting connection hole on the existing motorcycle cylinder head cover shell are arranged, so that the strength of the whole structure is reduced.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems in the prior art, the utility model provides a magnesium alloy motorcycle cylinder head cover shell.
The utility model is realized in such a way that the cylinder head cover shell of the magnesium alloy motorcycle is provided with a cover body; be equipped with the erection joint hole on the housing body, seted up the spark plug mounting hole in the middle of the housing body.
Further, the cover body is integrally formed.
Furthermore, the number of the mounting connection holes is four, and the four mounting connection holes are respectively located at four corners of the cover body.
Further, the number of the spark plug mounting holes is two, and the two spark plug mounting holes are arranged in an up-and-down mode.
By combining all the technical schemes, the utility model has the advantages and positive effects that:
the cover hood body is provided with the mounting connecting hole, and the spark plug mounting hole is formed in the middle of the cover hood body, so that the strength of the whole magnesium alloy cylinder head cover hood shell can be improved.
The cover body is integrally formed, so that the weight can be reduced, and the cover body has a protection effect on an air inlet system, an oil injection system and an ignition system of a motorcycle engine.
The four mounting connection holes are respectively positioned at four corners of the cover body, so that the whole cover can be conveniently fixed.
The two spark plug mounting holes are arranged up and down, so that the spark plugs can be conveniently mounted and dismounted.
