Claim:
1. A brake disc assembly comprising: a hub member for connection to a wheel hub; a rotor member including an annular portion and a plurality of support limbs that protrude radially inward from an inner peripheral face of the annular portion and are joined to a periphery of the hub member; and a plurality of air guide plates disposed in a circumferential direction about a central axis of the hub member and each substantially interposed in a gap between adjacent two of the support limbs of the rotor member, each of the air guide plates having a first opening and a second opening, each of the air guide plates having a first air deflector and a second air deflector, the first and second air deflectors being alternatively located on opposite sides of each air guide plate, the first and second air deflectors being disposed proximate the respective first and second openings to cause airflow to go around the rotor member, the first and second air deflectors of each of the air guide plates having a curved or angulated directing surface that alters a course of air encountering the directing surface such that all the air deflectors together direct the airflow generally in a circumferential direction, the first air deflector is located on a first side of the opposite sides of the associated air guide plate to cause the airflow to pass through the first opening from a second side of the opposite sides of the air guide plate to the first side, and the second air deflector is located on the second side of the air guide plate proximate the second opening to cause the airflow to pass through the second opening from the first side to the second side.
