Abstract: The brake caliper unit has two caliper levers whose one ends are linked to brake pads and whose other ends are linked to a slack adjusting device extending between them. The central regions of the caliper levers are coupled to a housing, in which case the coupling point of one caliper lever is constructed as a simple rotary bearing. The coupling point of the other caliper lever is constructed as an eccentric transmission which can be operated by a brake cylinder held in the housing by a crank arm in the direction of the approach of the two caliper levers. The eccentric transmission has a shaft which is rotatable in the housing about an axis and which, with an eccentricity directed diagonally away from the brake disc carries a pin with the axis on which the caliper lever is disposed. The eccentric transmission permits a high power transmission ratio with relatively short caliper levers.

Abstract: In a block brake with brake block regulator, which maintains the brake block shoe (6) in a predetermined rotational position about its rotational axis (5) through friction blocks (20) and friction surfaces (14), the friction surfaces (14) are in the form of wedge surfaces, such that, upon rotation of the brake block shoe (6) under the influence of gravity, the friction blocks (20) must be forced back through the friction surfaces (14) against their spring loading (18). This enables compensation of the turning moment brought to bear on the brake block shoe (6) by the gravitational force.

Abstract: The block brake unit for rail vehicles has a service brake which includes a transmission lever which is pivoted by a brake piston to shift an actuating rod coupled with a brake block carrier. A parking brake includes a spring-loaded cylinder which is coupled by a pivotable parking brake lever through a transmission lever to the actuating rod. An impact wedge coupling comprising a roller and wedge surface is provided between the parking brake lever and the transmission lever. By a suitable choice of the inclination and shape of the wedge surface, the transmission ratio for the parking brake can be readily adjusted for requirements in particular situations without the necessity for changes of the exterior dimensions or mounts and without any changes of the transmission ratio for the service brake. The wedge surface can also be constructed to provide a constant progressive or decreasing transmission ratio and also a fast application for the parking brake.
