Abstract
A rotor arrangement for the brake system of a vehicle has first and second annular rotor plates substantially in parallel, with a ventilated region therebetween for cooling the rotor plates. A plurality of airfoil-shaped structures is arranged in the ventilated region, each being coupled at one portion thereof to the first rotor plate, and at a second portion thereof to the second rotor plate, to maintain the first and second rotor plates in fixed spatial relation. The first and second rotor plates and the airfoil-shaped pillar structures are integrally formed, the interior surfaces of the rotor plates being configured as an annular venturi that increases the air flow therebetween. The airfoil-shaped structures are configured as airfoil-shaped pillars and fins to form a corresponding plurality of effective venturi nozzles whereby the flow of air between the rotor plates is laminar and increased to enhance the cooling of the annular rotor plates.
