Rotor with tubular vent ducts

摘要

The present invention discloses a vented brake rotor having tubular ducts. The rotor includes universal rotor blank having a hat section and a peripheral section radially extending therefrom. The hat section includes a mounting face and hat wall extending from the periphery of the mounting face. The peripheral section includes a first and a second braking plate joined together in a parallel, spaced apart relationship by a plurality of spacers. A plurality of duct tubes are fastened to the inner surfaces of the braking plates. Each one of the duct tubes has an inlet and an outlet allowing air to flow through the duct tube to provide an airflow path between the braking plates for cooling the rotor. In an alternate embodiment, the present invention may include a plurality of fins fastened to the inner surfaces of the braking plates. The fins extend between the braking plates forming a passages between them. A plurality of duct tubes are fastened in the passages between the fins.
