Abstract:
A hybrid drive system which has: a torque amplify mechanism (12) coupled to an output member (2) of an internal combustion engine (1) and an output member (9) of an electric motor (6), as energized by an electric power to output a torque, for amplifying and outputting the torque, as outputted from said internal combustion engine (1), by controlling a torque of said electric motor (6); and a continuously variable transmission (21) arranged between torque amplify mechanism (12) and said output shaft (34) for increasing/decreasing and outputting a motive power inputted from said torque amplify mechanism (12),characterized by a forward/backward switching mechanism (29) interposed between said torque amplify mechanism (12) and said output shaft (34) 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.
