<p>The invention concerns a device for setting the brake shoes of a drum brake and adjusting these brake shoes with respect to wear. According to the invention, the brake lining carriers (2) are supported at one end (2a) via an adjustable support (4) on a brake anchor plate (1) and can be spread apart at their other end by means of the brake-application device. The adjustable support (4) comprises a bush (7), which is provided with an abutment (7b) and is secured on the brake anchor plate (1), and a threaded sleeve (8) which is supported in this bush (7) and in whose internal screw thread (8a) a threaded bolt (9) held non-rotatably by the brake lining carriers engages. As a result of rotation, the threaded sleeve (8) brings about a variation in the spacing between the ends (2a) of the brake lining carriers. In order to enable the brake shoes to be set or adjusted easily even when the available space is limited, a pinion (10), which is provided with an actuating element or a key surface (10b) for a tool and whose teeth (10a) mesh in a self-locking manner with teeth (8b) on the threaded sleeve (8), is rotatably mounted on the brake anchor plate (1).</p> |
