<p>A brake anchor plate (12), which grips the peripheral edge of a brake disc (10), comprises two brake shoes (24, 26) each fitted to one side of the brake disc (10). The brake has an actuation system (22) with an actuation axis (B) which, together with the brake disc axis (A) defines a radial middle plane (C). Two guide pins (18, 20) are arranged on the brake anchor plate (12) at least approximately parallel to the brake disc axis (A) on the side of the middle plane (C) which, in relation to the direction of rotation (D) of the brake disc (10) during forward motion, is the outgoing side. A saddle (16) on the brake anchor plate (12) can be moved by means of the guide pins (18, 20). The actuation system (22) operates directly on one braking shoe (24), and, via the saddle (16), on the other braking shoe (26). The brake anchor plate (12), during forward motion, has guide surfaces (34, 36) for the brake shoes (24, 26) which are effective only on the outgoing side. The saddle (16) has, during reverse motion, support surfaces (40, 41) which are effective for the brake shoes (24, 26); the brake anchor plate (12) and saddle (16) are mutually linked, by an additional sliding connection, on the side which lies opposite to that of the brake actuating device (22), which is effective when braking during reverse motion and thereby relieves at least partly the guide pins (18, 20) of the momentum of the saddle (16) in relation to an axis which is perpendicular to the brake disc axis (A) and to the actuation axis (B).</p> |
