Abstract:
An arrangement for preventing squealing of a disk brake having a brake disk comprising:brake linings which have a circumferential lining length in a relationship with an approximately median circumference of the brake disk by which an imposed natural oscillation mode of the brake disk with n-nodes is obtained, inner and outer friction rings of the brake disk which include at least one slot provided in at least one surface area of the friction rings to produce a local weakening of a section modulus so that a detuning node oscillation, which is unequal to the natural oscillation mode of the brake disk, can be achieved, the at least one slot extending in a direction from the brake disk center to approximately an outer edge of the brake disk, and ribs connecting the inner and outer friction rings and forming cooling ducts, wherein said at least one slot is arranged to extend at least on one of said ribs forming the cooling duct, penetrates a friction surface of at least one of the friction rings, and ends in the one of said ribs, wherein the one of said ribs forming the cooling ducts has a larger width than another immediately adjacent rib of a smaller width, and wherein at least one of the ribs having the larger width is provided with the at least one slot which approximately follows a course of the at least one of the ribs and penetrates the outer friction ring.
