Title:
VEHICULAR DRIVING DEVICE AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2021095956
Kind Code:
A
Abstract:
To provide a technology capable of simplifying a manufacturing step of a vehicular driving device.SOLUTION: A vehicular driving device includes a rotary electric machine, a first gear integrally rotating with a rotor of the rotary electric machine, a counter gear mechanism 3 equipped with a second gear 31 engaged with the first gear and a third gear 32, a differential gear mechanism 4 equipped with a fourth gear 41 engaged with the third gear 32, a first bearing B41 rotatably supporting the differential gear mechanism 4 with respect to a case 5, and a second bearing b32 rotatably supporting the counter gear mechanism 3 with respect to the case 5. The rotary electric machine and the differential gear mechanism 4 are coaxially disposed, and the rotary electric machine and the counter gear mechanism 3 are disposed so as to have different axes. The fourth gear 41 is disposed so as to overlap with the second bearing B32 in an axial direction view. An interval W1 between the second bearing B32 and the forth gear 41 in an axial direction L is larger than dimensions W2 in the axial direction L of an area where a first outer ring B41a and a first inner ring B41b of the first bearing B41 are overlapped in a diametrical direction view.SELECTED DRAWING: Figure 3
