Abstract
An apparatus is furnished for the automatic adjustment of a brake in particular of a vehicle brake. The invention device provides generous assembly tolerances while employing relatively simple device components. The drive of the slack adjustment device (2, 4), formed from the gear rack drive (8, 9, 12), is surrounded in longitudinal direction of the gear rack by free spaces (30, 31), which furnish an appropriate clearance space to the gear rack (9). A pinion engages a second set of gear teeth of the gear rack. The pinion and a lost motion device drive the slack adjustment device. The drive device formed by the gear wheel, by the gear rack and by the pinion is disposed between the brake lever and a slack adjustment device. The device is suitable, in particular, to be employed in a brake lever with an automatic slack adjustment device.
