Multi-piece rotor for use with an electric wheel end drive motor

A process of assembling a brake disc arrangement to be located at an end of an axle of a vehicle driven by an electric motor disposed adjacent to a wheel hub of the vehicle, the brake disc arrangement providing for braking an individual vehicle wheel to be driven by the electric motor and comprising:

• assembling the electric motor to the wheel hub;
• sliding the wheel hub on the axle;
• securing an adaptor to at least one of the wheel hub and the individual vehicle wheel;
• joining multiple rotor assembly pieces, including rotor sections defining an engagement portion having surfaces to be contacted by friction pads, an attachment base, and an intermediate section, together with fasteners to form a rotor assembly, so that the intermediate section surrounds a rotor assembly axis of rotation and extends along the rotor assembly axis of rotation between the engagement portion and the attachment base;
• and
• attaching the rotor assembly to the adaptor, to extend between a base of the wheel hub and the attachment base of the rotor assembly, to enclose a housing of the electric motor within an internal volume within which the housing of the electric motor and at least a portion of the wheel hub are receivable.
