Abstract
What is provided is a power transmission unit and a power system according to one aspect of the present disclosure, including: an input shaft connected to a drive shaft of an internal combustion engine; an output shaft connected to a driven apparatus in a power transmittable manner; a transmission mechanism connecting the input shaft to the output shaft; and a motor generator including a rotary shaft connected to the input shaft and the output shaft via the transmission mechanism. When viewed in an axial direction of the input shaft, the motor generator is disposed outward from the input shaft in a radial direction crossing the axial direction.
Claims7
A power transmission unit comprising:
- an input shaft connected to a drive shaft of an internal combustion engine;
- an output shaft connected to a driven apparatus in a power transmittable manner;
- a transmission mechanism configured to connect the input shaft to the output shaft;
- and
- a motor generator including a rotary shaft connected to the input shaft and the output shaft via the transmission mechanism,
- wherein the transmission mechanism includes:
- a relay mechanism configured to connect the rotary shaft to the output shaft;
- and
- a one-way clutch configured to transmit a driving force of the input shaft in one direction to the rotary shaft and the output shaft via the relay mechanism and disconnect a driving force between the relay mechanism and the input shaft, which is generated by the rotary shaft and the output shaft to rotate the input shaft in the other direction, and
- when viewed in an axial direction of the input shaft, the motor generator is disposed outward from the input shaft in a radial direction crossing the axial direction.
