Abstract
The rotor of an electric motor unit has a web portion partially enclosing the remainder of the unit and terminating in a circumferentially extending rim. The brake drum defines an engagement surface for drum brake linings, and has an outboard end defining a flange securable to the wheel hub. The brake drum also includes an open inboard end, partly covered over by a dust guard, and a circumferential wall extending between the outboard and inboard ends and surrounding the engagement surface. By way of keys and slots or recesses, a reinforcing ring interlocks the circumferentially extending rim of the web portion and the circumferential brake drum wall. The reinforcing ring is secured to the circumferentially extending rim and to the wall of the brake drum at a location disposed axially between the rim of the web portion and the brake drum lining engagement surface.
