ABSTRACT:
A torque feedback multistate transmission employing an adjustable differential transmission with one or more planetary gear systems for providing improved efficiency under stationary load conditions and infinitely variable output during each state of the transmission. In one embodiment there is provided a pair of planetary gear systems, a reversing mechanism, a first transmission to establish the state, and a second transmission to provide continuous power flow during shifting of the first transmission. A differential transmission provides continuous variable output during each state of the multistate transmission.
