Abstract

The invention relates to a modular brake lining system, in particular for a brake disc (4) of a disc brake, moreover in particular for rail vehicles, having mounting plates (7, 8, 12) held on at least one rear part (9) and having a plurality of different friction segments (5, 6, 10, 11), wherein different friction segments (5, 6, 10, 11) have friction surfaces having different geometries and/or different sizes and/or different coefficients of friction and/or of different friction materials and wherein, as required, different friction segments (5, 6, 10, 11) of the brake lining system can be fastened to the mounting plates (7, 8, 10, 11). According to the invention, by changing the arrangement of the friction segments (5, 6, 10, 11) on the brake lining (1) and/or by changing the number of identical or different friction segments (5, 6, 10, 11), the maximum clearance diameter (d1, d2) of a clearance circle (13, 14) positioned beyond the central transverse axis (Y) of the brake lining (1) tangentially to at least two, preferably at least three, adjacent friction segments (5, 6, 10, 11) is adjustable to a value between 5 and 40 mm.

Abstract

The invention relates to a brake block (1) comprising a brake block holder for generating a braking force by frictionally contacting a friction surface (3) of a brake block rubbing surface (2) of the brake block with a running surface of a wheel of a rail vehicle. Said brake block rubbing surface (2) is made of a soft friction material having a hardness of preferably less than 400 N/mm2, more preferably less than 350 N/mm2, in particular less than 220 N/mm2, and/or has an elasticity module of preferably less than 20.000 N/mm2, more preferably less than 5.000 N/mm2, in particular less than 2.500 N/mm2, and particularly preferably, a composite material and/or compound material with an organic binding system, in particular a resin-bonded friction material, is provided as friction material. According to the invention, the brake block rubbing surface (2), on the side of the friction surface (3), has at least one material recess (5), said friction surface (3) being interrupted by the material recess (5) and the proportion of the total recessed surface (A) over the entire surface of the brake block rubbing surface (2) is more than 15 %.

Abstract

The invention relates to a composite brake pad (1) made of metal, in particular of cast iron, for a composite brake block (19), particularly for railway vehicles, wherein the composite brake pad is provided with a plate-shaped basic body (2) having a bearing surface (3) on an inner side (4) for a plastic composition of the composite brake block. The basic body (2) is provided with at least one steel insert (5), wherein, preferably, holding journals (6, 7) for the plastic composition are provided on the inner side (4) of the basic body (2). The steel insert (5) essentially has a non-rectangular cross-section across the entire length of the basic body, preferably an annular cross-section.

Abstract

A brake block for railway vehicles is depicted and described, comprising a cast iron brake block rear and a plastic material that is fixedly connected to the brake block rear. The brake block rear has a curved plate-shaped base (2) with an internal support surface (3) for the plastic material on an internal face (4). A total braking surface of the brake block is formed predominantly by at least one external surface of the plastic material and to a lesser extent by at least one external surface of the brake block rear. According to the invention, the base is designed without a frame on the longitudinal sides (5, 6) and comprises a cheek-shaped sidewall (9, 10) on each transverse side (7, 8). The plastic material is placed between the sidewalls. Each sidewall has at least one interruption (13, 14) that runs from the upper face of the sidewall in the direction of the support surface and subdivides the sidewall into at least two web-shaped sidewall sections (15-18). Faces of the sidewall sections form part of the total braking surface.
