Disc brake with operating piston displaceable with wear on brake blocks - has brake operating cylinder running into cooling fluid storage chamber which is enclosed by cooling ribs

摘要

The volume of the storage chamber (8) has at least 40 % of the displacement volume (F.s) which is produced when the operating piston (4) guided in the brake cylinder (3) is displaced. The cooling ribs (11 to 14) on the housing wall (15) run across the travel direction of the brake. The storage chamber is enclosed by the iron or steel housing of the brake cylinder which dissipates the heat. ADVANTAGE - Improved cooling of brake fluid so that overheated fluid cannot enter the brake lines.
