ABSTRACT:
An improved vehicle disc brake rotor is disclosed having a unique vented design. The rotor includes a pair of brake friction plates maintained in spaced relationship by a plurality of radially extending fins. Each friction plate is tapered radially from the outer peripheral end to the inner peripheral end thereof such that the friction plates have an increased cross-sectional thickness at the outer end. In addition, each fin is "blended" into the friction plates. Such a configuration increases the heat capacity and stiffness at the outer end of the rotor. A separate radially extending cooling air passageway is defined between each pair of the fins. The air passageway is configured to define a cross-sectional area which is substantially uniform throughout its entire length. This results in the velocity of cooling air being increased as it flows through the passageway, thus improving cooling efficiency.
