Title:
DRIVE UNIT FOR VEHICLE
Document Type and Number:
Japanese Patent JP2019189051
Kind Code:
A
Abstract:
To avoid that lubrication performance with respect to a power transmission mechanism becomes instable due to an airflow which is generated by the rotation of a planetary gear device when generating power by rotationally driving a generator by an engine via the planetary gear device.SOLUTION: A ring gear 24r of a planetary gear device 24 is non-rotatably held by an accommodation case 60, and when generating power by rotationally driving a first motor generator MG1, the motor generator MG1 is rotationally driven by an engine 16 via a carrier 24c and a sun gear 24s. Therefore, it can be avoided that a spray state of oil scooped up by a differential device 48 with respect to a power transmission mechanism 58 becomes instable due to an airflow generated by the rotation of the planetary gear device 24 like the case that the planetary gear device 24 is integrally rotated, and lubrication performance with respect to the power transmission device 58 is thereby stabilized.SELECTED DRAWING: Figure 1
