Abstract

A vehicle drive unit has an electric machine and a manual gearbox with first and second shift elements and two planetary gear sets coupled to one another. Each gear set has a sun shaft, a ring gear shaft, and a web shaft. The second sun shaft is drivable by the electric machine and is configured as an output of the shift gear. The second ring gear shaft is connected rotationally fixed to the first web shaft, and the first sun shaft is connected rotationally fixed to a stationary component. When actuated, the first shift element connects the first ring gear shaft to an element of the first planetary gear set and/or of the second planetary gear set. When actuated, the second shift element connects the first ring gear shaft rotationally fixed to the second sun shaft or the second web shaft in order to shift a second gear.
