In a power-split transmission for driving a first and a second axle of a motor vehicle, in the case of which transmission are located a first and a second output shaft (3, 4) and a friction clutch (12), the latter is intended to transmit a controllable torque. For this purpose, a) for the action of pressure upon the pressure plate (29), there are provided two rotationally uncoupled ring parts (31, 32) which are coaxial to the friction clutch and at least one of which possesses ramps rising in the circumferential direction, b) the two ring parts (31, 32) are supported in the axial direction and each possess a ramp lever (35, 36), the free end (37, 38) of which cooperates with a control unit (11) which moves the ramp levers in opposite directions, c) the control unit (11) having a rotatable control disk (40) with two slots, and the drive means being an electric geared motor. Various drives of the control disk and, if appropriate, of the shift of a reduction stage are also described.
