1-6. (canceled)
A hybrid drive train of a motor vehicle comprising:
- a transmission (1),
- a transmission oil sump (2) associated with the transmission (1),
- at least one electric machine, and
- a power electronics unit associated with the electric machine, and
- a structural space (3) being provided for the power electronics unit, which is located under the transmission oil sump (2) of the transmission (1).
A hybrid drive train of a motor vehicle comprising a transmission (1) with an oil sump (2), which is coupled to a lower side of the transmission (1), at least one electric machine with a power electronics unit, the power electronics unit being arranged in a structural space (3) located below the oil sump (2) of the transmission (1).
A hybrid drive train of a motor vehicle comprising a transmission (1), an oil sump (2), an electric machine with an associated power electronics unit and a thermally conductive area (6), the power electronics unit is accommodated in a structural space (3), the transmission (1) is coupled to a top side of the oil sump (2) and the structural space (3) is coupled to a bottom side of the oil sump (2) opposite the transmission (1) with the thermally conductive area (6) being located between the oil sump (2) and the structural space (3) such that oil in the oil sump (2) contacts the thermally conductive area (6) and cools the power electronics unit in the structural space (3).
