Abstract

An electric drive axle arrangement for a road vehicle comprises an electric drive motor (1), a differential mechanism (3, 4) for allowing different velocities of drive wheels driven by the drive motor, and a torque vectoring system (2, 6, 7) for controlling the distribution of drive torque between the two drive wheels. A torque vectoring motor (2) of the torque vectoring system is of the non-permanent magnet motor type.
