Problems solved by technology

[0009] In this case, choosing a larger size, that is, choosing a larger backplane thickness, is not an alternative in this regard, because it brings higher acquisition and / or manufacturing costs
[0010] Due to the edge-side recesses of the support grid in the area of ​​the breakout of the back plate, only a relatively small contact surface is available for the connection of the support grid to the brake pad, so that the tightness of the brake pad is not optimally achieved. solid

Embodiment Construction

[0033] exist figure 1 shows a brake shoe 1 comprising a lining carrier 2 and a brake shoe block 3 fastened thereto, which preferably consists of a composite material and is substantially concavely curved in the direction of longitudinal extension.

[0034] The lining support 2 matches it, and the lining support has a back plate 4 and a support grid 7 connected thereto, on which the brake shoe block 3 is fastened.

[0035] On the side of the back plate 4 opposite the support grid 7 , in the end region viewed in the longitudinal direction, there are provided profiled elements 5 which, in order to prevent the brake shoe 1 from twisting, engage with the brake shoe, not shown. corresponding to the holder.

[0036] exist figure 2 These shaping elements 5 can also be seen clearly in FIG. 2 , which additionally has a rectangular shape.

[0037] In addition, positioning pins 8 are arranged on this side of the back plate 4 , which are produced like the profiled elements 5 by deep dr...

Abstract

Disclosed is a brake shoe for a rail vehicle wheel brake, comprising a lining support (2) that supports a brake shoe rubbing surface (3) and includes a sheet metal backplate (4) and a supporting grating (7) which is connected to the backplate (4) and to which the brake shoe rubbing surface (3) is joined. The backplate (4) is provided with shaped elements (5) on the side facing away from the supporting grating (7) in order for the backplate (4) to rest in a twist-proof manner on a brake shoe holder, and is provided with shaped elements (6) on the side facing the supporting grating (7) in order for the backplate (4) to interlock with the supporting grating (7). The disclosed brake shoe is designed in such a way that the shaped elements (5, 6) provided on both sides of the backplate (4) have the shape of cups obtained by a deep drawing process.

Description

technical field [0001] The invention relates to a brake shoe for a wheel brake of a rail vehicle according to the preamble of claim 1 and to a method for producing the brake shoe. Background technique [0002] Shoe brakes for rail vehicles are known from the prior art, which have a brake shoe which can be pressed against the tread of a rail wheel by means of a pressing device. [0003] For the actuation of the shoe brake, a shoe holder is provided which is designed to press the brake shoe against the tread of the rail wheel in order to generate friction. [0004] In this type of brake shoe, the brake shoe block consists of a friction material which is bonded to the lining carrier by gluing, wherein the friction material is pressed into the openings of the support grid and likewise into the back plate (the support grid is connected to the back plate) in the edge side fracture. [0005] For the connection, rivet pins are welded on the back plate on the side facing the suppor...
