Sub-assembly for e-axle

A sub-assembly for limiting differential motion to an electric axle (eAxle) with a differential configured to differentially output torque about an axis, comprising:

• an actuator configured to generate a rotational force about the axis;
• a cam mechanism configured to convert the rotational force into a thrust force in a direction of the axis;
• a clutch assembly including a first drum drivingly engaged by a spline or keyway coupling with a differential case of the differential and a second drum drivingly engaged by a spline or keyway coupling with a side gear of the differential, and a friction clutch arranged between the first drum and the second drum, the clutch assembly being disposed adjacent to the cam mechanism so as to receive the thrust force to bring the friction clutch into action;
• and
• a cover configured to enclose the cam mechanism and the clutch assembly and to combine with the eAxle to support any one of the cam mechanism and the clutch assembly against the thrust force or a thrust reaction force.
