Abstract
A torque vectoring device directs different torques at will to the two wheels of a drive axle on a road vehicle. It has two hydraulically controlled disc clutches, connected to a drive shaft, extending through the device, and in engaged condition intended for connecting the drive shaft to either of two gear sleeves, each in splines engagement with an eccentric tube eccentrically journaled in relation to the drive shaft, and a torque transmitting mechanism with a gear ratio of 1:1 between the eccentric tube and a differential case sleeve, coaxial with the drive shaft and forming part of a differential case of a differential on the drive axle, to which differential the torque vectoring device is connected.
