Abstract
A hybrid drive system comprising: a torque amplify mechanism coupled to an output member of an internal combustion engine and an output member of an electric motor, as energized by an electric power to output a torque, for amplifying and outputting the torque, as outputted from the internal combustion engine, by controlling the torque of the electric motor; and a continuously variable transmission arranged between torque amplify mechanism and the output shaft for increasing/decreasing and outputting the torque inputted from the torque amplify mechanism. Further comprised is a forward/backward switching mechanism between the torque amplify mechanism and the output shaft for setting a forward state, in which the inputted motive power is unreversed and outputted, and a backward state in which the inputted motive power is reversed and outputted. As a result, the reverse run can be made only with the motive power outputted from the internal combustion engine.
