Abstract

A drive device of a hybrid vehicle includes a motor generator and a motor generator arranged at the back of the motor generator, each rotor having a rotational center axis arranged on the same axis, a power split mechanism arranged on the same axis as a rotational center axis of a crankshaft and between the crankshaft and the motor generator, and a power control unit performing control of the motor generator. The power control unit includes a reactor arranged in a gap portion formed on one side with respect to the rotational center axis of the motor generator and between a lower side surface of the power element substrate, an outer circumferential side surface of the motor generator and an inner side surface of a case, and a capacitor arranged on the other side with respect to the rotational center axis of the motor generator.

Claims14

Dependent claims

A drive device of a hybrid vehicle comprising:

a damper having a crankshaft of an internal combustion engine coupled thereto;
an electric rotating machine having its rotational shaft arranged to overlap with a rotational shaft of said damper;
a power transmission mechanism combining motive power generated by said internal combustion engine with motive power generated by said electric rotating machine for transmission to a drive shaft;
a power control unit performing control of said electric rotating machine;
and
a case accommodating said damper, said electric rotating machine, said power transmission mechanism and said power control unit, wherein
said power control unit includes
a circuit substrate having a power element of at least one of an inverter and a voltage converter mounted thereon, and
a reactor arranged, if being projected from said rotational shaft direction, in a gap portion formed inside a horizontal dimension of a projection portion of that part of said case which accommodates said damper, said electric rotating machine, said power split mechanism, and said circuit substrate at a time of being mounted on a vehicle.
