SUBSTANCE: drive device comprises a wheel unit (103) defining the axial direction and the radial direction, a first torque transmission device (111) and a second torque transmission device (112). The first torque transmission device is torsionally rigidly connected to the wheel unit and the second torque transmission device is torsionally rigidly connected to the first torque transmission device using the connecting device (114), so that the device becomes coaxial to the axial direction. The wheel unit comprises an end portion (103.1) of the wheel unit, projecting along the wheel axis into the opening (112.1) in the second torque transmission device. The protective unit (115) is located between the end portion of the wheel unit and the second torque transmission device, the protective unit being configured to protect the end portion of the wheel unit from damage by the second torque transmission device in the event of a failure of the connecting device.
