Abstract:
1. A drive apparatus for a hybrid vehicle, comprising: a first motor generator that functions as one of a motor and a generator; a power splitting mechanism portion that divides power generated by an engine into power for the first motor generator and power for a driven wheel; a second motor generator which is arranged on a side of the first motor generator opposite the engine, which functions as one of a motor and a generator, which generates power for driving the driven wheel that is different from the power from the engine, and which has an outside diameter smaller than an outside diameter of the first motor generator; and a speed reducing mechanism portion which is arranged on a side of the second motor generator opposite the engine, which has an outside diameter smaller than an outside diameter of the second motor generator, and which reduces a rotation speed of the second motor generator, wherein the speed reducing mechanism portion is operable to reduce only a rotation speed of the second motor generator when the power generated by the engine is transmitted to the driven wheel.
