Abstract
A cam actuated drum-type brake having an improved mounting arrangement for the power unit that actuates the brake. The actuator for the brake includes a camshaft rotatably journaled within a tube that is affixed to the backing plate and to which is affixed a mounting bracket that mounts the power unit. The mounting bracket has a mounting portion for the power unit and is disposed at an angle to the axis of rotation of the brake drum and also at an angle to a plane perpendicular to the axis of the drum. The arrangement is such that the mounting bracket may be moved without necessitating disassembly of the brake or removal of the brake drum.
Claims8
A mounting arrangement for a power unit of a drum brake having backing plate fixed relative to an associated drum rotatable about a rotational axis, a pair of brake shoes supported for movement relative to said backing plate from a retracted position to an engaged position within the associated brake drum, cam means for actuating said brake shoes comprising a camshaft supported for rotation about an axis offset from said rotational axis, an actuating lever affixed to said camshaft for rotating said camshaft and actuating said brake shoes, a mounting bracket affixed to said backing plate in proximity to said lever, said mounting bracket comprising first and second angularly related planar elements and a third planar element integral with the perpendicular to both elements, said third element extending from and end region of said second element to a point beyond the junction between all of said elements, said third element being inclined with respect to said rotational axis and providing attachment means for attaching the power unit to said bracket said first element forming an opening for securing said mounting bracket to said backing plate.
