Abstract
The present invention relates to a vehicle brake and hub comprising a ring braking member having braking surfaces both to the interior and exterior of the member in combination with a cast hub which includes centrally disposed aligned bearing ports for receiving bearings. The cast hub includes an outwardly exposed securing surface which cooperates with the ring braking member to effect securement of the braking member to the casting and in a manner to accommodate heat transfer therebetween. The cast hub includes intermediate the securing surface and the align ports, fan blades which cause during rotation of the hub an axial flow of air to move across the bearing ports and to extract heat from the fan blades and the securing surface. The fan blades collectively interconnect and structurally secure the securing surface and the bearing ports.
Claims5
A vehicle brake comprising
- a ring braking member having braking surfaces to both the interior and exterior of said member,
- a hub including a central port for mounting of bearings, said hub being connected to said ring braking member by means of radial members spaced about said hub and having air passages therebetween, said radial members being orientated to draw an air flow through the center of the brake, said air passages accommodating said air flow through said brake which passes over an exterior surface of a shield, which exterior surface is located radially inwardly of and adjacent to said ring braking member opposite said interior braking surface,
- said shield cooperating with said interior braking surface to shield said interior braking surface from dirt and water contained in any air flow through the center of the brake and to transfer heat energy of said interior braking surface to said air flow via said shield, and
- a brake calliper arrangement positioning braking pads either side of said braking surfaces which commonly brake said ring brake member when applied thereto by said brake caliper.
