DRUM BRAKE

摘要

A brake has a pair of brake pads (12), each pad being moveable generally radially outwardly into contact with a brake drum by a respective operating lever (14) acted on at one end by a brake applying means (15) and pivoted (16) at the other end from a backplate (11). Each pad is contacted by a portion (14c) of the respective operating lever intermediate the lever ends and moving radially outwardly between a pair of circumferentially spaced abutments (45) which extend generally perpendicular to the backplate and which react braking torque when the brake is applied. One end of each abutment (45) is supported from the backplate and the other free ends of the abutments is linked circumferentially (46) to each other to brace the pair of abutments against relative circumferential deflection when the brake is applied. The pivots (16) of the levers may also be connected by a bracing link (75) to help to control the deflection of the pivots when the brake is applied.
