Problems solved by technology

[0004] However, there are disadvantages in the existing lubrication method of internal parts of the engine
[0005] The method of pressure oil supply needs to process multiple predetermined oil circuits on the part, and the processing hole system is more, and the processing cost is high
[0006] However, parts are splashed and lubricated by splashing oil. The method of collecting lubricating oil and dripping lubrication by ribs and bosses requires the engine speed to reach a higher speed. It is difficult for the boss to collect enough lubricating oil to lubricate the corresponding parts

Embodiment 1

[0037] see Figure 1 to Figure 6, this embodiment provides a lubricating structure, including a crankcase body, a cylinder block, a cylinder head, a cylinder head 100, and an oil pump 210; The interior of the cylinder head 100 has a predetermined oil passage 110 for lubricating oil to flow, and the oil pump 210 can drive the lubricating oil to flow in the predetermined oil passage 110; the crankcase body is provided with an oil storage The crankcase body, cylinder block, cylinder head, and cylinder head are provided with first lubricating oil passages connected in sequence, through which the lubricating oil in the oil storage part is sent through the lubricating oil filter device and oil pump in sequence, The lubricating oil is delivered to the cylinder head 100 sequentially from the crankcase body, the cylinder block, and the cylinder head, and lubricates the air distribution system in the accommodating space; the first lubricating oil circuit includes the predetermined oil c...

Embodiment 2

[0047] see Figure 1 to Figure 6 , this embodiment is improved based on embodiment 1.

[0048] In the lubricating structure, there are multiple ridges 160, and multiple oil guide grooves 150. The multiple oil guide grooves 150 correspond to the multiple ridges 160 one by one, and the oil collecting grooves 140 of each ridge 160 respectively pass through the corresponding oil guide grooves. 150 communicates with the oil outlet 130 .

[0049] In this embodiment, by arranging a plurality of bulges 160 and a plurality of oil guide grooves 150, the proportion of lubricating oil entering each oil guide groove 150 after flowing out from the oil outlet 130 can be increased, that is, the amount of lubricating oil flowing out from the oil outlet 130 can be reduced. The ratio of the lubricating oil that does not enter the oil guide groove 150 and directly drops, so as to better control the dripping position of the lubricating oil, so as to improve the lubricating effect on the rotating ...

Embodiment 3

[0051] see Figure 1 to Figure 6 , this embodiment is improved based on embodiment 2.

[0052] In the lubricating structure, a plurality of oil guide grooves 150 are sequentially arranged on the outer side of the oil outlet 130; the oil outlet 130 includes a plurality of predetermined arc-shaped edges, and the plurality of predetermined arc-shaped edges correspond to the plurality of oil guide grooves 150 one by one, and each predetermined arc The arc-shaped edges are respectively located in the corresponding oil guide grooves 150, and multiple sections of predetermined arc-shaped edges are connected end to end.

[0053] In this embodiment, by arranging the predetermined arc-shaped edges in the corresponding oil guide groove 150 to be end-to-end, that is, when the lubricating oil flows to the edge of the oil outlet 130, the lubricating oil must be on one of the predetermined arc-shaped edges , and can enter the oil guide groove 150 from a predetermined arc edge. As a result,...

Abstract

The invention relates to the technical field of motorcycles, and discloses a lubricating structure, an engine and a motorcycle. The lubricating structure comprises an air cylinder cover and an oil pump. A preset oil way for lubricating oil to flow is arranged in the air cylinder cover, and the oil pump can drive the lubricating oil to flow in the preset oil way. The surface of the air cylinder cover is sunken to form a sunken part, and an oil outlet communicating with the preset oil way is formed in the inner wall of the sunken part. The surface of the air cylinder cover protrudes to form a protruding part with a tip, and an oil gathering groove extending to the tip is formed in the side face of the protruding part. The inner wall of the sunken part is sunken to form an oil guide groove, and the oil gathering groove communicates with the oil outlet through the oil guide groove. According to the lubricating structure, the engine and the motorcycle, when the lubricating structure is applied to the engine in a low-speed operation state, a good lubricating effect can still be achieved on the engine, and abrasion of components of an air distribution system caused by low-speed operation of the engine is avoided.

Description

technical field [0001] The invention relates to the technical field of motorcycles, in particular to a lubricating structure, an engine and a motorcycle. Background technique [0002] During the operation of the motorcycle engine, there needs to be sufficient lubrication between various moving parts of the gas distribution system and various matching parts of the transmission system to ensure that the engine can work with low friction and high efficiency under various working conditions. [0003] As the lubrication methods of the internal parts of the engine, there are usually: pressure oil supply lubrication, parts stirring and splashing lubrication, ribs and bosses collecting lubricating oil and dripping lubrication, etc. [0004] However, there are drawbacks in the existing lubricating methods for the internal parts of the engine. [0005] The method of pressure oil supply needs to process multiple predetermined oil circuits on the part, and the processing hole system is...
