A drive deviceA includes: electric motorsA andB that outputs drive powers; and planetary gear reducersA andB disposed between axlesA andB connected to cylindrical shaftsA andB serving as the output shafts of the electric motorsA andB and to rear wheels LWr and RWr. The drive deviceA further includes: a one-way power transmission device that transmits the one-way rotation power of the electric motorsA andB to the axlesA andB; and a two-way power transmission device that transmits the two-way rotation power of the electric motorsA andB to the axlesA andB. The one-way power transmission device and the two-way power transmission device are disposed on transmission passages from the electric motorsA andB to the axlesA andB.

Drive device and vehicle with same

A power unit which makes it possible to reduce power transmitted from a prime mover to a driven part via an electrical path, to thereby increase the efficiency of driving the driven part. A first rotating machine of the power unit inputs and outputs energy between a stator and first and second rotors thereof, via magnetic circuits formed by generation of a rotating magnetic field, and the rotating magnetic field, and the rotors rotate while maintaining a linear relation in which respective differences in rotational speed between the rotating magnetic field and the second rotor, and between the second and first rotors are equal. The rotors are mechanically connected to a prime mover and a transmission, respectively. A second rotating machine of the power unit is mechanically connected to a drive part without via the transmission, and electrically connected to the stator.

Power unit

A power control unit for electric vehicle which can easily detach the high voltage cables even if the motor room is deformed, for example, by head-on collision and/or rear-end collision of the vehicle, which is difficult to be deformed, which can make small, and which can avoid an influence of heat generated by the reactor is disclosed. The power control unitincludes a boxwhich accommodates devices for controlling electric power supply of the electric vehicle; a reactor receiverwhich is provided on a given external surface around the boxand supports a reactor R; a heat sinkconnected to the lower end of the reactor receiver, covering the bottom surface of the box, possessing passages including passage wall inside thereof, and performing heat-exchange with the boxby allowing coolant water to flow within the passage; and a partition, which is laid on at least one side of the boxextending toward the longitudinal direction of the vehicle EV, and is detachably communicated with cables to be connected to the traction motordisposed below the heat sinkto supply power.
