ABSTRACT:
A floating-frame spot-type disc brake is described comprising a floating frame (1) guided in a manner axially displaceable on a brake carrier (12), and being furnished with two brake cylinders (2, 3) and two brake pistons (4, 5) directly acting on two axially inwardly disposed brake shoes (6, 7). The brake carrier (12) is located entirely on one side of the brake disc and no portion extends across the outer edge of the brake disc (15), so that the maximum diameter of the brake disc is limited only by the relatively thin sections of the floating frame (1) extending across the outer edge of the brake disc. Additional brake shoes (8, 9, 22), on the axially outer side, are fixed to the floating frame (1), in turn transmitting the circumferential force acting on the outer shoes occurring during braking, through a bolt guide (10), into the brake carrier (12).
