Abstract
A fluid cooled vehicle brake includes a fluid flow passage disposed in fluid communication with a brake shoe rim carrying a layer of friction material. A pair of spaced support webs are coupled to an inner surface of an annular inner surface of the rib. A water jacket is sealingly joined to the pair of webs and the inner surface of the rim to form a fluid flow passage between an inlet port formed in one of the support webs along the inner surface of the rim and out through an outlet port formed in one of the support webs. High thermal conductive members may be disposed within the layer of friction material to conduct heat to the rim. Heat radiator members are mounted within the coolant passageway.
Claims13
A liquid cooled vehicle brake shoe comprising:
- a brake shoe having an annular rim carrying a layer of a brake friction material on a radially outer surface, a radially inner surface opposed from the outer surface;
- a pair of spaced rim structural support webs, each extending radially inward from the inner surface of the rim and joined to the inner surface of the rim along an annular edge, the webs defining a mounting surface for the brake shoe on a vehicle;
- and
- a water jacket sealingly joined to the first and second webs to form a closed interior defining a fluid flow passage between an inlet port and an outlet port formed in at least one of the webs for circulating fluid past the rim to remove heat from the layer of brake friction material.
