Embodiment Construction
[0024] As shown in the figure, the power transmission device can be applied to electric two-wheel vehicles and electric vehicles with more than two wheels, and is used for automatic gear shifting during the running of the vehicle.
[0025] The structure of the power transmission device includes a power input shaft 10 and a power output shaft 1. The outer circumference of the power input shaft 10 is fixedly provided with a main driving gear 9, and the outer circumference of the power output shaft 1 is fixedly provided with an active and passive gear 3. A plurality of transmission pairs are arranged on the periphery of the power output shaft 1 and the power input shaft 10. The transmission speed ratios of these transmission pairs are different. Corresponding to transmission pairs with different transmission speed ratios, the power output shaft 1 outputs power at different speeds.
[0026] The transmission pair includes a transmission shaft 5 and an auxiliary driving gear 7 and an...
