DRUM BRAKES

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. Each lever (14) is pivoted on the backplate (11) by a pin (16) which extends generally perpendicular to the backplate. The free ends of the pins (14) are connected by a bracing link (75) to help to control the deflection of the pins (16) when the brake is applied.
