ABSTRACT:
A transmission apparatus for a wheeled vehicle is disclosed. The wheeled vehicle includes a rotatable driving member, to which power is delivered by rotating the driving member in a first direction, and a ground engaging wheel. The transmission apparatus includes a cylindrical spring which encircles an axle of the ground engaging wheel. A first end of the cylindrical spring is connected to the axle, and a second end is connected to a one-way clutch mechanism which periodically engages an inner surface of a hub of the ground engaging wheel to periodically deliver energy stored in the spring to the wheel. An engaging mechanism, which is mounted on the axle adjacent to the clutch mechanism, is capable of periodically engaging the clutch mechanism. A reversing mechanism, which links the engaging mechanism to the driving member, urges the engaging mechanism to periodically rotate the clutch mechanism in a second direction opposed to the first direction of rotation of the driving member, in order to periodically tension the spring and to periodically transfer energy to the spring.
