Abstract
A torque vectoring device (4-18) for two half-axles of a vehicle drive axle, provided with a conventional differential (20-27), through which drive torque is supplied from a propulsion motor, is connected on one hand to one of the half-axles (1), on the other hand to the cage (24) of the differential (20-27). An electric motor (15) of the torque vectoring device is connected via a differential transmission in the form of a planetary gearing (10) to said one of the half-axles (1) and the cage (24). The arrangement is such that the electric motor stands still, when the rotational speed of the half-axle (1) and the cage (24) is the same.
