ABSTRACT:
A differential (100) includes a clutch pack that is activated by rotational movement of a ball ramp (31) that results in a linear force applied to the reaction plates (41) and friction plates (42). The ball ramp (31) is controlled by a DC motor (114) that has a high efficiency of a gear train to allow the use of the DC motor to control the activation of the clutch pack.
