Abstract
A vented disc brake rotor is provided. In one embodiment, the rotor includes a plurality of curved directing walls disposed between first and second braking surfaces to define a plurality of flow channels. A separating wall is disposed in each flow channel to create first and second subchannels. The total cross-sectional area of each flow channel remains substantially constant over the length of the flow channel. The flow channels can be closed to the two braking surfaces. Alternatively, the braking surfaces can be intermittent, defining a plurality of gaps that provide access to the flow channels. A tapered throat region between the braking surfaces and a hat region facilitates dissipation of heat from the braking surfaces. Rotors according to the present invention can be fabricated in a single step using various conventional casting techniques, such as die-, sand- and squeeze-casting.
