PCT No. PCT/SE81/00344 Sec. 371 Date Jul. 7, 1982 Sec. 102(e) Date Jul. 7, 1982 PCT Filed Nov. 26, 1981 PCT Pub. No. WO82/01922 PCT Pub. Date Jun. 10, 1982.A brake adjuster for the automatic adjustment of vehicle brakes has a lever (13) which is connected to a brake cylinder (2) via a piston rod (1) and which, via a slack adjuster (15), is connected to a cam shaft (4) having a brake key (5) for brake application. The slack adjuster (15) cooperates via a one-way clutch (20) and a motion transmitter (28) with a control disc (39) fixedly attached to a bearing housing (9) for the cam shaft (4). The motion transmitter (28) is formed by a worm wheel (27) which, via said one-way clutch (20), is connected to said slack adjuster (15), and a worm (29) meshing with the worm wheel. The worm (29) is axially movable against the action of a spring (34) upon brake application and is non-rotatably connected to a pinion (31) which is connected to the control disc (39) to transfer the movement thereof, relative to the lever (13 ), to the worm (29). |
