The invention relates to a drive unit for a rail vehicle, said drive unit comprising a drive motor (1), a wheelset transmission (4), and a connection coupling for transmitting torque to a wheelset shaft (2), wherein the wheelset transmission is connected to the drive motor to form a motor-transmission unit and has a hollow shaft (3) acting as a transmission hub (3.1) for an output gear (7) of the wheelset transmission, wherein the connection coupling is designed as a toothed coupling in such a way that an internally toothed coupling sleeve (3.2), which is rigidly connected to the hollow shaft (3) or designed in one piece therewith, and an externally toothed output hub (11), which can be rigidly connected to a wheelset shaft (2), are engaged via toothing (3.2a) so that the drive torque can be transmitted, and a separate support element (12) is provided which supports part of the weight force of the motor-transmission unit outside the toothing (3.2a) on the output hub (11).
