Abstract
A disk brake for rail vehicles has an actuating device that has a lever designed to transfer deflections of a braking force generator to a pressure element. A parallel alignment of the pressure element, as well as of a brake pad pressed by the pressure element against a friction ring, is guaranteed by at least one slot guide between an at least approximately fixed part of the disk brake and the pressure element. The slot guide has two pins that engage displaceably and offset with respect to one another in two slot path segments which are designed to be at least approximately in the form of a segment of a circular arc and each have different radii.
Claims31
A disk brake assembly comprising:
- a brake frame,
- a brake actuating lever pivotally mounted at the brake frame,
- a pressure element pivotally connected to the actuating lever for movement about a pressure element pivot axis and operable to press a brake pad against a rub ring to apply braking forces to the rub ring, and
- a pressure element aligning assembly operable in use to maintain the pressure element and brake pad in alignment,
- wherein said aligning assembly includes:
- at least one slot guide with two slot path sections which are fixed with respect to one of the brake frame and pressure element and which extend along different paths with respect to the pressure element pivot axis, and
- a pair of guide pins fixed with respect to the other of the brake frame and pressure element, said guide pins being spaced from one another and being engageable in respective ones of the slot path sections.
