ABSTRACT:
A mechanically ventilated disc brake rotor has internally housed centrifugal fan impeller rotates freely at one direction and engages with brake rotor in other direction with use of single direction ball bearing. While a vehicle travelling forward, centrifugal fan impeller rotates along with brake rotor at same speed and forces airflow out through the fixed vanes passages by centrifugal action and at the same time it gains angular momentum energy. Whenever brake's applied to slow down a forward moving vehicle, the rotation of brake rotor slows down. At this instant, single direction bearing gets disengaged from the brake rotor and continue rotating freely at same initial rotational speed with help of angular momentum effect. Continues rotation of centrifugal fan impeller, continue in forcing out air flow thru fixed vanes channels by centrifugal action providing enhanced and continues heat dissipation even though brake rotor rotation speed has slowed down or stopped.
