Abstract
An electrically actuated wheel hub clutch includes a clutch device. The clutch device alternately engages and disengages a wheel hub relative to an axle shaft. An electric motor actuates the clutch device. An electric circuit delivers electric current to the motor. The circuit includes a brush and a radially aligned slip ring arranged for relative rotation about an axis. The brush and slip ring are carried by respective holders. The brush holder includes at least one radial projection overlapping both the brush and slip ring to prevent relative axial disengagement therebetween.
