<P>PROBLEM TO BE SOLVED: To provide a hybrid driving device for achieving an electric traveling mode in such a state that an energy loss is suppressed while suppressing increase in size of an entire device or increase of manufacturing costs. <P>SOLUTION: The hybrid driving device H includes: an input member I; an output member O; a rotary electrical machine MG; and a differential gear unit PG1 having four rotary elements from the first to the fourth in the order of rotating speed. The differential gear unit PG1, in which the first rotary element is connected to the rotary electrical machine MG to be driven and in which the third rotary element is connected to the output member O to be driven, includes: a brake B2 for selectively fixing the second rotary element to a non-rotary member; and a clutch C1 for selectively connecting the fourth rotary element to the input member I for driving. The hybrid driving device includes a stepped shift mode in which the rotating speed of the input member I is shifted by a prescribed shift rate corresponding to each shift stage to be transmitted to the output member O, and an electric traveling mode in which the torque of the rotary electric machinery MG is transmitted to the output member O in such a state that the brake B2 is put in an engaged state and the input member I is separated from the output member O. <P>COPYRIGHT: (C)2011,JPO&INPIT |
