Abstract

Provided is a unit including: a heat exchanger; and a housing configured to accommodate a differential gear mechanism, in which the housing has a portion having an inclined surface surrounding the differential gear mechanism in a radial direction, and the heat exchanger has a portion that overlaps the inclined surface when viewed in an axial direction.

Claims (26)

1 . A unit comprising:

a motor;

a housing configured to accommodate a differential gear mechanism, the differential gear mechanism being connected downstream of the motor; and

a heat exchanger positioned outside the housing, wherein

the housing has a portion having an inclined surface surrounding the differential gear mechanism in a radial direction,

the heat exchanger has a portion that overlaps the inclined surface when viewed in an axial direction,

the inclined surface has a portion positioned between the differential gear mechanism and the heat exchanger, and

the heat exchanger does not overlap the motor when viewed in the radial direction.

2 . The unit according to claim 1 , wherein

the heat exchanger has a portion that overlaps the inclined surface when viewed in the radial direction.

3 . The unit according to claim 2 , wherein

the differential gear mechanism has a portion that overlaps the motor when viewed in the axial direction, and

the heat exchanger has a portion that is positioned above a horizontal plane passing through an axis of an output shaft of the differential gear mechanism and orthogonal to a gravity direction.

4 . The unit according to claim 1 , wherein

the differential gear mechanism has a portion that overlaps the motor when viewed in the axial direction, and

the heat exchanger has a portion that is positioned above a horizontal plane passing through an axis of an output shaft of the differential gear mechanism and orthogonal to a gravity direction.

5 . The unit according to claim 1 , wherein

the heat exchanger has a shape including an arc-shaped portion disposed to surround an axis of an output shaft of the differential gear mechanism when viewed in the axial direction.

6 . A unit comprising:

a housing configured to accommodate a differential gear mechanism including a differential case and a differential gear set in the differential case; and

a heat exchanger positioned outside the housing, wherein

the differential gear mechanism has a portion that overlaps a motor when viewed in an axial direction,

the heat exchanger has a portion that overlaps the housing when viewed in the axial direction, and

the heat exchanger is positioned above the differential case in a gravity direction.

7 . The unit according to claim 6 , wherein

the heat exchanger has a shape including an arc-shaped portion disposed to surround an axis of an output shaft of the differential gear mechanism when viewed in the axial direction.
