Embodiment Construction
[0028] The following is a specific embodiment of the present invention and in conjunction with the accompanying drawings, further describes the technical solution of the present invention, but the present invention is not limited to this embodiment.
[0029] Such as figure 1 and figure 2 Shown, in the air-cooled device of this motorcycle speed changer, speed changer comprises the driving pulley 2 that is connected on the engine power output shaft 1, and the engine output shaft 1 is the crankshaft of engine in the present embodiment, and on the outside wall of driving pulley 2 A plurality of fan blades are provided to form a fan 21. This air-cooling device includes a transmission box cover 3 fixed on the gearbox casing. The transmission box cover 3 is fixedly connected to the main cover body 32 on the motorcycle body and the cover is located on the main cover. The wind guide 33 on the outer wall of the body 32 is connected by bolts between the wind guide 33 and the main cover...

The invention provides an air cooling device of a motorcycle transmission, and belongs to the technical field of motorcycles. The problem that rainwater and impurities of an existing air cooling device easily affect the service life and the transmission efficiency of a transmission is solved. The air cooling device of the motorcycle transmission comprises a fan arranged on a power output shaft ofan engine and a transmission case cover internally provided with an air guide chamber, an air inlet is formed in the transmission case cover, an air outlet communicated with the air guide chamber andright opposite to the fan is formed in the transmission case cover, and a water retaining protruding edge is arranged on the side wall of the air guide chamber. The water retaining protruding edge isarranged around the air outlet to form an air inlet channel, an inlet of the air inlet channel is formed downwards, the air inlet is formed in the top wall of the transmission case cover and located above the water retaining protruding edge, and a water outlet is formed in the bottom of the transmission case cover. Rainwater and impurities carried by the rainwater are effectively prevented from entering the air outlet, so that the service life and the transmission efficiency of the transmission are not easily influenced by the rainwater and the impurities thereof.
Description
technical field [0001] The invention belongs to the technical field of motorcycles and relates to an air cooling device for a motorcycle transmission. Background technique [0002] The CVT continuously variable transmission is a transmission device that uses belts, driving pulleys, and driven pulleys to transmit power to achieve continuous change in transmission ratio. For the CVT continuously variable transmission, the service life of the belt, the driving pulley and the driven pulley and the transmission efficiency directly affect the operation effect of the transmission. [0003] CVT continuously variable transmission will generate more heat during operation, so how to effectively dissipate it is very important. In the prior art, the cooling of the belt and other parts of the CVT continuously variable transmission is usually provided with an air inlet on the transmission case cover, and fan blades are arranged on the outer wall of the driving pulley at the same time, and...
