Abstract
Provided is a drive apparatus of a hybrid vehicle, configured in such a manner that the occurrence of a resonance phenomenon is minimized and that the efficiency of utilization of the space occupied by a torque limiter mechanism is improved. A drive apparatus for a hybrid vehicle is configured in such a manner that a torque limiter is provided in the path of power transmission between an inner shaft and a generator at a position between the generator and a motor. The torque limiter axially overlaps with at least a part of the stator of the generator and/or at least a part of the stator of the motor.
Claims3
A drive apparatus of a hybrid vehicle comprising:
- an engine;
- a first shaft disposed coaxially with an output shaft of the engine and configured to transmit a power of the engine;
- a second shaft disposed parallel to the first shaft and including an inner shaft which is connected to rotate interlockingly with the first shaft and an outer shaft which is disposed around the inner shaft so as to be rotatable with respect to the inner shaft;
- a first electromotor connected to the inner shaft for transmitting power;
- and
- a second electromotor disposed coaxially with the first electromotor and connected to the outer shaft for transmitting power,
- wherein a torque limiter mechanism is:
- provided in a power transmission path between the inner shaft and the first electromotor at a position between the first electromotor and the second electromotor,
- overlapped in an axial direction with at least a portion of a stator of the first electromotor and/or a stator of the second electromotor, and
- disposed in a torque limiter accommodating chamber which is provided in a case and into which oil is supplied,
- wherein the torque limiter accommodating chamber includes a first oil passage which is communicated with the first electromotor and a second oil passage which is communicated with the second electromotor at a vertically lower part of the torque limiter accommodating chamber.
