ABSTRACT:
A multi-speed transmission for transmitting power between a first shaft and a second shaft includes a plurality of gear sets, a plurality of connector gears corresponding to the plurality of gear sets and a shifting mechanism. Each gear set includes a first gear rotatably disposed about the first shaft, a uni-directional free wheeling mechanism between the first gear and the first shaft, and a second gear coupled to the second shaft. The uni-directional free wheeling mechanism permits the first gear to freely rotate about the shaft when the first gear rotates in a preselected direction relative to the rotation of the first shaft and locks the first gear to the first shaft at all other times. The first and second gears are spaced apart from one another but may be interconnected by one of the plurality of connector gears. Each connector gear is movable between an engaged position and a disengaged position. In the engaged position, each connector gear mutually engages the first gear and the second gear of the gear set. In the disengaged position, each connector gear is disengaged from the first gear and the second gear. The shifting mechanism moves each one of the plurality of connector gears between the engaged position and the disengaged position. The shifting mechanism maintains at least one of the plurality of connector gears in the engaged position at all times.
