Problems solved by technology
Therefore, there is a small interference fit between the steel ball and the cover body. During the running of the motorcycle, the steel ball is likely to fall off due to the impact of vibration, causing the lubricating oil to flow out from the longitudinal oil passage, so that the lubricating oil cannot reach the cylinder head in time. cam rocker arm, making it wear out badly
At the same time, after the steel ball falls off, the lubricating oil will flow out from the longitudinal oil passage and cannot return to the crankcase, which will cause the engine to work in the absence of lubricating oil, which will easily cause serious wear and tear of the engine in a short period of time. Cylinder pistons sintered together, causing the crank and connecting rods to lock up, eventually killing the engine

Embodiment Construction
[0014] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0015] like figure 1 and figure 2 As shown, the present invention is made by mold casting, has a cover body 1, and a circular oil inlet groove 3 is provided on the mounting surface 2 of the cover body 1, and a boss 4 is integrally formed on the mounting surface 2 of the cover body 1, A camshaft positioning pin hole 5 is opened on the boss 4 , the camshaft positioning pin hole 5 is a stepped hole, and the camshaft positioning pin hole 5 penetrates to the back of the mounting surface 2 . At the bottom of the oil inlet groove 3, an oil guide groove 6 is provided. The oil guide groove 6 is elongated and extends toward the boss 4. The length direction of the oil guide groove 6 is between the oil inlet groove 3 and the camshaft positioning pin hole. 5 on the central line. A part of the notch of the oil guide groove 6 penetrates to the bottom of the oil inlet g...

The invention discloses a right cover of a motorcycle engine air cylinder head. An oil inlet slot (3) is arranged on an installation surface (2) of a cover body (1), wherein a boss (4) is integrally formed on the installation surface (2) of the cover body (1); a cam shaft positioning pin hole (5) is arranged on the boss (4); an oil guide slot (6) is arranged on the bottom of the oil inlet slot (3); an oil path (7) is arranged between the oil guide slot (6) and the cam shaft positioning pin hole (5); and the oil guide slot (6) is communicated with the cam shaft positioning pin hole (5) by the oil path (7). The right cover of the motorcycle engine air cylinder head can effectively prevent lubricating oil from flowing away, can ensure the oil path to be unblocked for a long time while avoiding resource waste and environment pollution, so that the lubricating oil entering the engine air cylinder head is sufficient, and the defects caused by lack of lubricating oil are overcome. Besides, the right cover has the characteristics of delicate design, simple structure, easiness in machining and manufacturing, high production efficiency, low cost, and the like, and is applicable to various motorcycle engines.
Description
technical field [0001] The invention relates to a motorcycle component, in particular to a cylinder head right cover on a motorcycle engine. Background technique [0002] The right cover of the cylinder head is an important part of the motorcycle engine, and the oil channel layout on the right cover of the cylinder head plays a vital role in the lubrication effect of the engine. like image 3 , Figure 4 As shown, the right cover of the cylinder head has a cover body 1, and an oil inlet groove 3 is provided on the installation surface 2 of the cover body 1, and a boss 4 is integrally formed on the installation surface 2 of the cover body 1, and a boss 4 is formed on the boss 4. Camshaft positioning pin hole 5 is arranged, and camshaft positioning pin hole 5 communicates with oil inlet groove 3 through longitudinal oil passage 8 and transverse groove 9. Since the longitudinal oil passage 8 and the transverse groove 9 intersect vertically, and the intersection point is insid...
