Transmission system for electric carrier e.g. electric bike, has one-way bearings arranged between transmitting gears and shafts, which cooperate with motor to switch power transmitting route for changing speed of vehicle

摘要

The one-way bearings (A11,B11,A21,B21) positioned between the transmitting gears (G1,G2) and the shafts (S1,S2), cooperate with a motor (M1) rotating in clockwise or anti-clockwise direction to switch power transmitting route for changing speed of a vehicle.
