Abstract
The present invention is applied to pedal vehicles, or mixture of electric and pedal vehicles, or combination of electric and pedal auxiliary vehicles, especially to a bicycle capable of being pedaled bidirectionally and driven to move in unidirectional, and through the torque limit transmission being transferred into overload sliding or disengaging status, the retrograde torque limit bicycle with bidirectional input and one-way output is prevented from being locked.
Claims16
A bicycle propulsion system with bidirectional input and one-way output, said bicycle propulsion system including a torque limited retrograde transmission device that enables a bicycle to be move backwards without being locking, comprising:
- a human input device for receiving a bidirectional input and transmitting said bidirectional input to said torque limited retrograde transmission, said bidirectional input including inputs in either of two rotary input directions or a reciprocating input;
- and
- a load wheel set driven by said one-way output of said torque limited retrograde transmission, wherein:
- said torque limited retrograde transmission device converts said bidirectional input into a one-way output to cause said bicycle to move in a forward direction, thereby allowing a rider to move the bicycle in a forward direction while supplying an input in either of the two rotary input directions, and
- said torque limited retrograde transmission device includes a torque limiting component arranged to transfer said torque limited retrograde transmission to a sliding or disengaged status to prevent locking when a reverse torque from reverse movement of the load wheel set exceeds a set overload torque.
