<P>PROBLEM TO BE SOLVED: To provide a hybrid driving device that has good efficiency of power transmission and thus improves fuel consumption. <P>SOLUTION: The hybrid driving device includes engaging mechanisms C1, B1 and B2, the mechanisms making predetermined rotation elements in a power-distribution planetary-gear mechanism 4 and speed-up-and-down planetary-gear mechanisms 5 and 6 selectively connect with other predetermined members. In addition, the hybrid driving device sets a plurality of driving modes. The engaging mechanism includes: an engaging mechanism C2 for maximum speed that engages in order to set a maximum speed mode where the number of revolutions of a motor becomes relatively low; and an engaging mechanism C1 for non-maximum speed that engages in order to set other driving mode. The engaging mechanism C2 for maximum speed is constructed by a geared type engaging mechanism, and the engaging mechanism C1 for non-maximum speed is constructed by a friction type engaging mechanism. <P>COPYRIGHT: (C)2012,JPO&INPIT |
