A differential transmission comprises a differential casing (16) driven by an input shaft and having compensating gears (20) mounted therein, and in each case having an output gear (21, 22) to drive a first and a second output shaft (3, 4), it being possible for the differential casing to be connected to one of the output shafts (3, 4) via a friction clutch (12) by pressure being applied to a pressure plate (29). In order not to have to introduce any actuating forces into the casing and to achieve the short switching times required for electronic slip regulation, a) for the axial displacement of the pressure plate (29), two rings (31, 32) decoupled in terms of rotation with balls (33) between them are provided, of which at least one has ramps that rise in the circumferential direction, and b) both rings (31, 32) each have a ramp lever (35, 36) whose free end (37, 38) interacts with a control unit (11), which has electric drive means (46, 54) and moves the ramp levers in opposite directions.
