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.
Claims12
A liquid cooled vehicle brake shoe comprising:
- an annular rim carrying a layer of a brake friction material on a radially outer surface, the rim having a radially inner surface opposed from the radially outer surface;
- a first and second spaced rim structural support webs, each extending perpendicularly to and radically inward from the radially inner surface of the rim and joined to the radially inner surface of the rim along an annular edge, the first and second spaced rim structural support webs comprising a mounting surface for a brake shoe on a vehicle;
- and
- a water jacket sealingly joined between the first and second spaced rim structural support webs circumferentially beyond the annular extent of an inlet port and an outlet port formed in at least one of the first and second spaced rim structural support webs to form a closed interior defined by the water jacket, the first and second spaced rim structural support webs, and the inner surface of the rim and comprising a fluid flow passage between the inlet port and the outlet port for circulating fluid in heat transfer relationship directly over the radially inner surface of the rim to remove heat from the layer of brake friction material.
