An axle drive for distributing torque from a propeller shaft to two axle shafts of a motor vehicle axle which is not permanently driven, having two torque transmitting friction couplings which are arranged in the coupling housing and intended to drive the axle shafts, and having two actuating devices for the two friction couplings. There is provided a common pump housing which is non-rotatably connected to the coupling housing and which contains two symmetrically and axially movably arranged pistons delimiting one end of pressure chambers each filled with a highly viscous fluid and connected to a reservoir. Pumping and control members are arranged opposite the pump housing between two end positions so as to be rotatable to a limited extent. The pressure chambers each contain conveying members which are each non-rotatably connected to one of the axle shafts. Rotational faces of a conveying member, together with counter-faces of the pumping and control member, constitute at least one sealed shear channel. In the two end positions of a pumping and control member, one control aperture arranged in the direction of relative rotation at the front end of the groove communicates with the reservoir and a control aperture arranged in the direction of relative rotation at the rear end of the groove communicates with the pressure chamber, so that in the shear channel there occurs a shear action from the reservoir to the pressure chamber.
