Abstract
A differential assembly includes an electrically operated input device and a first planetary assembly in driving engagement with the input device. The first planetary assembly is drivingly connected to a first output assembly. A second planetary assembly is in driving engagement with the first planetary assembly and the second planetary assembly is drivingly connected to a second output assembly. The first planetary assembly co-acts with the second planetary assembly to provide substantially the same torque to the first and second output assemblies and the first and second planetary assemblies include axes of rotation substantially aligned with an axis of rotation of the input device.
