Description

TECHNICAL FIELD

[0001] The utility model relates to motorcycle engine oil gas separation technical field, concretely relates to a clutch side cover with oil gas separation function and motorcycle engine. BACKGROUND

[0002] With the promotion of modern motorcycle engine performance and strengthening degree, the heat load of hot machine part and gear pair when the engine runs will also be obviously improved. Meanwhile, the clutch plate and the pressure plate combine and separate frequently during the motorcycle driving, and the friction will generate a large amount of heat, which will make the temperature of the lubricating oil in the clutch system rise, and part of the lubricating oil will be vaporized into oil gas. Especially when driving for a long time at high speed, frequently shifting or driving in complex road conditions such as mountainous areas, the clutch is used frequently, more heat is generated, and the oil gas phenomenon will be more obvious. The motorcycle engine oil gas separation technology is to prevent the oil gas mixture from flowing back to the intake system, so as to pollute the air, reduce the engine efficiency, and even cause engine damage. Due to the limited structure size of the motorcycle engine, the size and weight of the oil gas separation device are important factors to be considered in design, and the old oil gas separation structure cannot provide sufficient oil gas separation efficiency, so that the engine cannot meet the emission requirements. SUMMARY

[0003] In view of the above technical problems of the prior art, the utility model solves the technical problems: how to provide a clutch side cover with oil gas separation function which can utilize the remaining space in the engine clutch to improve the oil gas separation efficiency.

[0004] In order to solve the above technical problems, the utility model adopts the technical scheme of:

[0005] A clutch side cover with oil gas separation function, comprising a side cover body, a labyrinth cover plate arranged inside the side cover body, a side rib protruding on the inner side surface of the side cover body, the side rib and the labyrinth cover plate can be folded to form an oil gas separation cavity, an oil gas separation channel is arranged in the oil gas separation cavity, an air inlet hole is arranged on one end of the side rib corresponding to the oil gas separation channel, and an exhaust channel for exhausting air outward is arranged on the other end of the side rib corresponding to the oil gas separation channel.

[0006] The oil gas generated in the motorcycle engine clutch enters the inlet end of the oil gas separation channel through the air inlet hole under the action of pressure, and when passing through the circuitously arranged oil gas separation channel, the oil gas collides with the side wall of the oil gas separation channel, and then the liquid drops in the oil gas are attached to the side rib, that is, the gas part and the liquid part in the oil gas are separated, that is, the oil gas is preliminarily separated on the basis of the original motorcycle engine structure, and then the oil gas separation device on the original engine is used for separation treatment, so that the separation efficiency and effect of the oil gas are improved; and the oil gas separation cavity newly arranged in the side cover utilizes the empty space in the original engine cavity, and does not cause any influence on the external dimensions of the original engine.

[0007] As an optimization, the position of the air inlet hole is located at the opposite position of the side rib along the rotation direction of the clutch. When the clutch rotates, the liquid thrown out is easily thrown into the oil gas separation cavity, so that the air inlet hole is arranged in the opposite direction, so that this situation can be avoided,

[0008] As an optimization, the inner wall of the side rib is alternately protruded to form a protruding rib on the opposite side, and the oil gas separation channel for the oil gas to pass through is formed between all the protruding ribs. By arranging the alternately protruding protruding ribs on the opposite sides, the circuitous oil gas separation channel can be formed in the oil gas separation cavity.

[0009] As an optimization, the protruding ribs are respectively arranged to be inclined towards the direction of the air inlet hole. The oil liquid attached to the inner wall of the side rib can flow towards the direction of the air inlet hole and flow out of the oil gas separation cavity.

[0010] As an optimization, a boss is protruded on the inner wall of the side rib corresponding to the position of the exhaust passage, and the inlet end of the exhaust passage is located on the top surface of the boss. The oil liquid on the inner wall can be prevented from flowing to the exhaust passage.

[0011] As an optimization, an inlet circular arc surface is protruded on the inner wall of the side rib on the side of the air inlet hole, and an outlet circular arc surface is protruded on the inner wall of the side rib corresponding to the position opposite to the inlet end of the exhaust passage. When the oil gas enters, it will impact on the inlet circular arc surface, and when the oil gas goes out, part of the oil gas will also impact on the outlet circular arc surface, which can further improve the separation of the oil liquid in the oil gas and make it adhere to the surface.

[0012] As an optimization, the labyrinth cover plate and the side rib are sealingly connected through bolts.

[0013] The application also discloses a motorcycle engine, and the motorcycle engine is provided with the clutch side cover with the oil gas separation function as described above on one side, and the oil gas separation cavity is located on the inner side of the motorcycle engine.

[0014] As optimization, the motorcycle engine is provided with an oil-gas separation device, and the outlet end of the exhaust passage is connected with the inlet end of the oil-gas separation device.

[0015] Compared with the prior art, the oil-gas separation cavity is arranged on the inner side of the engine clutch side cover, the oil-gas is preliminarily separated on the basis of the original engine structure, and then enters the oil-gas separation device of the engine for further separation, thereby improving the separation efficiency and separation effect of the oil-gas, reducing the pollution emission of the engine, and protecting the environment.
