Abstract
A brake shoe assembly comprising a brake shoe to which brake plates are assembled. The brake shoe and brake plates are connected by a key or tang in one to a key way or slot in the other. Preassembled fasteners are provided on the brake plates to facilitate alignment of the brake plates with the brake shoe so that the key is received in the slot. Fasteners may be provided in four open corner areas so that the brake plate may be secured to the brake shoe with metal-to-metal contact where the brake plate is secured to the brake shoe. A brake shoe having a cylindrical outer surface or an outer surface defined by a plurality of flats is provided.
Claims18
A brake shoe assembly comprising:
- a brake shoe having an outer radial surface, a plurality of receptacles passing through the outer radial surface, and a plurality of bore holes in the outer radial surface for preassembled fasteners;
- and
- a brake plate having a cylindrical backing plate and a frictional brake lining, wherein the cylindrical backing plate includes tangs that are partially severed from the backing plate to mate with respective receptacles for resisting movement of the brake plate relative to the outer radial surface of the brake shoe without the tangs passing completely through the brake shoe, and a plurality of preassembled fasteners spaced from the tangs and extending away from the brake lining and toward the brake shoe to facilitate alignment of the tangs with the receptacles, and wherein the frictional brake lining is molded to the backing plate to form a continuous molded layer that covers each of the preassembled fasteners, the brake lining being free of holes extending completely through the continuous molded layer;
- wherein the tangs and the receptacles supplement the preassembled fasteners in securing the brake plate to the brake shoe and particularly resist shear forces between the brake plate and brake shoe.
A brake shoe assembly comprising:
- a brake shoe having an outer radial surface, a plurality of receptacles passing through the outer radial surface, and a plurality of bore holes in the outer radial surface for preassembled fasteners;
- and
- a brake plate having a cylindrical backing plate and a frictional brake lining, wherein the cylindrical backing plate includes projections having edges extending away from the backing plate to mate with respective receptacles for resisting movement of the brake plate relative to the outer radial surface of the brake shoe without the projections passing beyond the receptacles in the brake shoe, and a plurality of preassembled fasteners spaced from the projections and extending away from the brake lining and toward the brake shoe to facilitate alignment of the projections with the receptacles, and wherein the frictional brake lining is molded to the backing plate to form a continuous molded layer that covers each of the preassembled fasteners, the brake lining being free of holes extending completely through the continuous molded layer;
- wherein the projections and the receptacles supplement the preassembled fasteners in securing the brake plate to the brake shoe and particularly resist shear forces between the brake plate and brake shoe.
