Embodiment

[0043] refer to figure 1 and Figure 14 , The split-type wheel-mounted brake disc for rail vehicles includes a split-type disc body 1, a spacer 2, bolts 3, nuts 4, positioning pins 5, O-rings 6 and wheels 7. The split disc body composition 1 is located on both sides of the wheel web 71 .

[0044] refer to Figure 2 to Figure 4, The single-piece split disc body composition 1 includes two split friction rings 11 , an integral steel frame 12 , a pressure block 13 , a rivet 14 and a slider 15 .

[0045] refer to Figure 5 to Figure 7 , the planes on both sides of the split friction ring 11 are the friction surface 111 and the chute surface 112 respectively, 6 friction ring through holes 114 are evenly distributed on the middle circle 113 of the friction ring, and 6 outer pressure blocks are evenly distributed on the friction surface 111 Slot 115 and four inner briquetting grooves 116; the outer briquetting groove 115 and the inner briquetting groove 116 are identical in struct...

Abstract

The invention belongs to the technical field of brake devices for rail vehicles, and in particular relates to a split wheel-mounted brake disc for rail vehicles. It consists of a two-component disc body. The split disc body consists of two semi-circular split friction rings, an integral steel frame, pressure blocks, rivets and sliders; the split friction ring passes through The pressure block, the rivet and the integral steel frame are riveted together; the integral steel frame is fixedly connected to the wheel through spacers, bolts and nuts. The split-type wheel-mounted brake disc of the present invention only needs to replace the worn-out split friction ring and rivets in the later stage, and does not need to disassemble and replace the integral steel frame, bolts, nuts, positioning pins and spacers. The quality frame is always fixed on the wheel, which greatly reduces the operation and maintenance cost of the brake disc.

Description

technical field [0001] The invention belongs to the technical field of brake devices for rail vehicles, and in particular relates to a split wheel-mounted brake disc for rail vehicles. Background technique [0002] At present, there are mainly two forms of wheel-mounted brake discs for rail vehicles: integral wheel-mounted brake discs and split-type wheel-mounted brake discs. [0003] The integral wheel-mounted brake disc is mainly composed of two integral disc bodies, positioning pins and fasteners. The integral disc body is an integral ring with a heat dissipation rib structure and chutes are distributed on the circumference of the heat dissipation rib side. and bolt holes; the positioning pin is a solid shaft, and the cylindrical surface at both ends of the cylindrical shaft is milled symmetrically to a certain depth along the axial direction. After milling, the two planes are symmetrically distributed with the center line of the cylinder; On the web of the wheel, bolt h...
