AUXILIARY ELECTRIC DRIVE WITH WHEEL HUB DISCONNECT

摘要

A powertrain includes an axle end assembly rotatable about a wheel axis. A wheel bearing housing rotatably supports an outer axle end of the axle end assembly. A wheel hub is rotatably supported by the wheel bearing housing for rotation about the wheel axis. A hub actuating system is coupled to the wheel bearing housing, and is selectively controllable between an engaged state for rotatably coupling the wheel hub and the outer axle end together, and a disengaged state for de-coupling the wheel hub and the outer axle end. At least one axle bearing interconnects and rotatably supports the outer axle end relative to the actuator housing so that the outer axle end and the wheel hub are axially stacked relative to each other along the wheel axis, and the wheel hub and the outer axle end do not radially overlap each other relative to the wheel axis.

1. A powertrain comprising:
a torque producing device; a differential coupled to the torque producing device; an axle coupled to the differential, and including an outer axle end rotatable about a wheel axis; a wheel bearing housing rotatably supporting the outer axle end of the axle; a wheel hub rotatably supported by the wheel bearing housing for rotation about the wheel axis; and a hub actuating system coupled to the wheel bearing housing and selectively controllable between an engaged state rotatably coupling the wheel hub and the outer axle end for co-rotation together about the wheel axis, and a disengaged state rotatably de-coupling the wheel hub and the outer axle end to allow the wheel hub to rotate relative to the outer axle end.
