Abstract

A torque vectoring device includes a drive member engaged with a power source, a plurality of variator ball assemblies configured to be tiltable and rotatable with respect to the drive member, a first output frictionally engaged with the variator ball assemblies, and a second output frictionally engaged with the variator ball assemblies. A torque distribution between the first output and the second output may be adjusted by tilting the plurality of variator ball assemblies. The variator ball assemblies also facilitate a differential action between the first output and the second output.
