Abstract

A hybrid drive unit (HY, G) for a motor vehicle includes a housing (GG), in which a torque converter (TC) and an electric machine (EM) are accommodated. The electric machine (EM) and the torque converter (TC) are arranged directly next to each other such that the electric machine (EM) is arranged at a first face end (TC1) of the torque converter housing (TCG). An oil guide shell (LS) at least partially encompasses a section of the torque converter (TC). The oil guide shell (LS) has an L-shaped cross-section including a first section (LS1) and a second section (LS2) and is arranged in such that the first section (LS1) partially encompasses a second face end (TC2) of the torque converter housing (TCG) and the second section (LS2) partially encompasses a circumferential surface of the torque converter housing (TCG).
