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