Unit with heat exchanger and housing accommodating differential gear
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.
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.
