Driving device and an electric motorcycle driving system using the driving device

Abstract

The present invention provides a driving device and an electric motorcycle driving system using the driving device. Said driving device comprises a shaft, a pulley disk assembly configured on the shaft, and a motor. The motor is an outer rotor or inner rotor motor. One pulley disk of the pulley disk assembly is connected to one end of the outer rotor sleeve or the inner rotor of the motor, so it can be driven by the outer rotor sleeve or the inner rotor and rotate or move around the shaft; furthermore, an electric motorcycle driving system can use the driving device to connect with a battery and a stepless speed change mechanism, so as to use the electric power of the battery to operate the stepless speed change mechanism, and to consequently enhance the performance of speed and torque output of the electric motorcycles.

What is claimed is: 
     
         1 . A driving device, comprising:
 a shaft;   a pulley disk assembly, provided on one end of the shaft in a rotatable manner, including a pulley disk and a substrate corresponding to each other, and a plurality of pulley rollers between the pulley disk and the substrate; the pulley disk can move on the shaft; and   a motor, configured on the other end of the shaft, comprising an inner rotor and such components as the stator coil provided on the outer side of the inner rotor; one end of the inner rotor is connected to the pulley disk, while the other end is sleeved on the shaft and is provided with a plurality of permanent magnets corresponding to the stator coil.   
     
     
         2 . The device defined in  claim 1 , wherein the motor further comprises a casing, provided on the shaft and covering the outside of the inner rotor, while such components as the stator coil are provided on the inner side of the casing. 
     
     
         3 . The device defined in  claim 1 , wherein the motor is in the style of a permanent-magnet brushless inner rotor motor.
