Abstract
A pedal shaft and a rear wheel shaft spaced apart from said pedal shaft are rotatably mounted in a supporting structure. An overrunning clutch is engageable to transmit torque to said rear wheel shaft from a chain drive, which is operatively connected to said pedal shaft. A motor is carried by said support and has a motor shaft, which is connected by a self-adjusting cone drive to said rear wheel shaft. An arbitrarily engageable one-way starting clutch is operatively connected on one side to said pedal shaft independently of said rear wheel shaft and on the other side is operatively connected to said motor shaft. Engagement of the overrunning clutch is controllable.
Claims6
A motor-assisted bicycle, comprising
- a supporting structure,
- a pedal shaft rotatably mounted in said supporting structure,
- a rear wheel shaft spaced apart from said pedal shaft and rotatably mounted in said supporting structure,
- a chain drive operatively connected to said pedal shaft,
- an overrunning clutch which is engageable to transmit torque from said chain drive to said rear wheel shaft,
- a motor carried by said supporting structure and having a motor shaft,
- a self-adjusting cone drive operatively connected to said motor shaft and to said rear wheel shaft,
- an arbitrarily engageable one-way starting clutch which on one side is operatively connected to said pedal shaft independently of said rear wheel shaft and on the other side is operatively connected to said motor shaft, and
- engagement-preventing means which are associated with said overrunning clutch and arbitrarily controllable to selectively permit and prevent its engagement.
