Abstract
An automatic adjustment apparatus for a friction brake containing at least two braking elements between which there is arranged a brake lining and which are pressed against one another in a braking position. At least one of the brake elements is adjustably arranged. There is provided a cylindrical portion having a shoulder, and disc-shaped adjustment elements are arranged upon the cylindrical portion to both sides of the shoulder. The disc-shaped adjustment elements are displaceable by means of the adjustable braking element which is movable relative to the shoulder upon wear of the brake lining. Upon such wear of the brake lining amounting to the thickness of an adjustment element or a predetermined fraction of such thickness, the adjustment element arranged directly at the shoulder upon the larger diameter part of the cylindrical portion is displaceable onto its smaller diameter part. Importantly, the disc-shaped adjustment elements comprise shaft securing rings which are under radial stress when seated upon the larger diameter part of the cylindrical portion and lose such radial stress when transferred to the smaller diameter part of the cylindrical portion.
