Abstract: A wheel hub having two separable components. The wheel hub includes a sleeve rotatably mounted to a vehicle axle. A wheel-mounting flange for mounting a wheel of the vehicle is positioned substantially around the sleeve, and a bolting lip of a brake rotor (or brake drum) is sandwiched between the wheel-mounting flange and a bolting flange of the sleeve.

Abstract: Exciter rings, wheel assemblies and methods of assembling. In some aspects, a wheel assembly includes a brake rotor including a barrel section having an interior surface defining a barrel cavity, and a projection extending from the interior surface of the barrel section into the barrel cavity. The wheel assembly also includes an exciter ring formed separately from the brake rotor and engagable with the projection within the barrel cavity to removably connect the exciter ring to the brake rotor. In other aspects, an exciter ring is formed separately from and removably connectable to a brake rotor and includes a body portion having an outer surface, the body portion including a detent protruding outwardly from the outer surface and extending around the outer surface of the body portion. The exciter ring also includes a flange extending radially outwardly from the body portion and having a plurality of apertures.
