The maintenance cost of scooter is higher than that of straddles and curved beams motorcycle, because scooters are infinitely variable, meaning they have no gears.The characteristics of scooter stepless transmission: it is to rely on the front drive plate and the rear clutch plate friction belt on both sides to change the transmission ratio, so as to realize the start, acceleration and deceleration.
In addition, there are several advantages of using variable speed belts instead of chains:
1. Low noise
2. No need to adjust tightness
3. Easy to replace
4. Smooth transmission, eliminating the need for damping rubber blocks in the rear wheel hub
5. Alleviate impact, absorb vibration, low cost, and convenient maintenance
6. Change the transmission ratio
The structural characteristics of the speed belt:
Its working surface has two inclined sides, and many of the inner layers of the belt are made into tooth shapes, because it is designed to take into account the force of the belt when it is at the position of the pulley wrap angle.When the belt moves, the outer layer is stretched, and the inner layer is mainly affected by the squeezing force. Therefore, the inner layer of the belt is made into a tooth shape, which is more suitable for the force of the belt in these working positions, thereby extending the belt Service life.
To put it simply, belt drive has the advantages of wide range of center distance, simple structure, stable transmission, buffer load and safety protection.
