Belt transmission can be used for transmission with large spacing between the two shafts, so in the design of most motorcycles, it is mostly used to connect the engine to the rear gear wheel box. Because belt transmission has the advantages of mitigating impact, absorbing vibration, less noise, low cost and convenient maintenance, it is beneficial to apply it to motorcycle transmission.
Because the V-belt can use the bevel to change the transmission diameter, it can also change the transmission ratio while reducing the transmission. The use of automatic clutch and automatic continuously variable transmission system saves the tedious task of manual shift in the control of motorcycle speed.
Driving is simplified to be like using a "fool's camera", so belt continuously variable transmission has become a popular urban model in recent years
Motorcycles are particularly popular, and have developed from simple light motorcycles to medium displacement scooters.
The disadvantages of easy slip and inaccurate transmission ratio of belt transmission are not a big problem in the driving transmission of motorcycle, so belt transmission can be widely used in civilian vehicles with convenient operation.
The belt has the disadvantages of poor heat resistance, poor overload resistance and easy aging, which can only be solved by improving the quality of the belt, so it is not used in vehicles that need to transmit high power.
For light motorcycles, the biggest disadvantage of belt transmission is large transmission damping, especially when the car is cold. Because the belt consumes part of the energy when transmitting power, the power performance of the belt car with the same displacement is not comparable to that of the sprocket car. Its specific performance is in taxiing and speed. The belt car is hard to implement. It seems to have a little brake when taxiing, and the maximum speed is greatly reduced. The fuel consumption of constant speed cruise is often 30-50% more than that of sprocket cars at the same level, and it is difficult to conduct fuel-saving test.
Another disadvantage of belt drive is that the lateral force of the bearing is too large, and most of the design of motorcycles are in the same direction as the work force, which makes the bearing more difficult to use on the belt car than on the sprocket car and easier to be damaged.
