ABSTRACT:
The invention concerns an automatic-adjustment drum brake. The brake comprises a support plate (10) which slidably carries two brake shoes (12, 14). An anchoring block (24) is disposed between first ends (20, 22) of the brake shoes (12, 14). A brake actuator (28) is disposed between the other ends (30, 32) of the brake shoe (12, 14). The brake actuator (28) cooperates with one of the brake shoes by way of an adjusting lever (44), the free end of which engages a unidirectional coupling (55) having a locking direction (A) and an adjustment direction. A strut member (34) and a spring (40) also engage the adjusting lever. The force of the spring (40) is such that as long as the brake shoes (12, 14) do not bear against the drum, the lever (44) is urged in the adjustment direction and the lever (44) is urged by the brake actuator (28) in the locking direction (A) when the brake shoes (12, 14) bear against the drum. The invention may be utilized for braking motor vehicles.
