Embodiment Construction

[0019] figure 1 A brake caliper arrangement 2 of a rail vehicle brake is shown, which interacts with a not shown brake disk. Brake caliper unit 2 in figure 1 is shown in the use position, ie the components shown above are also mounted above.

[0020] The brake caliper device 2 is actuated by an actuator 3 not described in detail here and acts on an eccentric shaft 4 with end eccentric journals, namely an upper eccentric journal 6 and a lower eccentric journal The journals 8 protruding from the housing openings 10 , 12 of the housing 14 of the brake caliper arrangement 2 are supported in a rotational manner on each of the brake caliper levers, ie an upper brake caliper lever 16 and an upper brake caliper lever 16 . In the lower brake caliper lever 18. exist figure 1 In the position of use shown in , the brake caliper arrangement 2 is arranged substantially horizontally, so that the upper brake caliper lever 16 is arranged at a higher level than the lower brake caliper le...

Abstract

The invention relates to a bearing arrangement between a housing (14) supporting an eccentric shaft (4) and at least one body (16, 18), in which an eccentric pin (6, 8) on the end of the eccentric shaft (4) protruding out of the housing (14) is rotatably supported and moves eccentrically when the eccentric shaft (4) is rotated relative to the housing (14) and thereby drives the body (16, 18), comprising at least one axial bearing (18, 44, 56) for transmitting axial forces from the body (16, 18) to the housing (14). According to the invention, the axial bearing is disposed in the axial direction of the eccentric pin (6, 8) between the body (16, 18) and the housing (14) or a component fixed to the housing, viewed in the axial direction of the eccentric shaft (4).

Description

technical field [0001] The invention relates to a brake caliper arrangement for a rail vehicle according to the preamble of claim 1 . [0002] Background technique [0003] A brake caliper arrangement of the same type is known from DE 44 31 353 C1. The known bearing arrangement is arranged in a brake caliper arrangement of a rail vehicle brake, the brake caliper arrangement comprising at least two eccentric shafts arranged on outer surfaces facing away from each other of the housing by each end side of the eccentric shaft. Journal eccentrically driven brake caliper lever. In this case, the caliper lever of the brake caliper assembly is rotatably mounted on the eccentric journal. The pliers lever is additionally connected axially to the eccentric journal of the eccentric shaft. [0004] In the known bearing arrangement, the annular flange of the pliers lever is slidably mounted on a cover disk that rotates with the running shaft, which in turn is supported axially relative...
