<p>In a disc brake, which can preferably be operated hydraulically, a piston (5) is guided inside a housing insert, located in a brake calliper, which piston (5), when subjected to pressure, may act against a brake shoe (15) supporting a brake lining (17) in such a manner that the brake shoe (15) with its brake lining is pressed onto the brake disc which is to be braked. On the side of the piston (5) facing the brake shoe there is provided a pressure plate (13) which is used for transmitting the pressure forces and has lateral mobility inside the recess (19), which holds it, of the piston (5). The pressure plate (13) is placed onto the end of a ram (25) which extends axially inside the piston (5), is supported on the opposite end, with respect to the pressure plate, by means of a disc (27) on the base (29) of the hole (31) holding the ram, and is surrounded by a pretensioned compression spring (37). Sideward movements of the pressure plate (13) lead to tipping of the ram (25) and, in consequence thereof, to a restoring force which is exerted by the compression spring (37) onto the ram (25) and hence onto the pressure plate (13), and which can be defined exactly by means of a variable position screwed ring (39) which supports one end of the compression spring (37). …<IMAGE>… </p> |
