Embodiment

[0045] refer to figure 1 , split shaft-mounted brake disc for rail vehicles, including two-component disc body 1, disc hub 2, pressure ring 3, bolt 4 and nut 5, split disc body 1, disc hub 2 and pressure ring 3 They are connected together by bolts 4 and nuts 5.

[0046] refer to Figure 2 to Figure 4 The split disc body composition 1 includes two semicircular split friction rings 11 , an integral steel frame 12 , a pressure block 13 , a rivet 14 and a slider 15 .

[0047] 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, and the friction surface 111 is evenly distributed with 6 outer briquetting grooves 113 and 4 inner briquetting grooves 114; the outer briquetting groove 113 and the inner The structure of the briquetting grooves 114 is exactly the same and is a T-shaped groove structure. The T-shaped grooves are divided into a large end 115 and a small end 116; accordi...

Abstract

The invention belongs to the technical field of rail vehicle braking devices, and in particular relates to a split shaft-mounted brake disc for rail vehicles. It includes a two-component disc body, a disc hub, a pressure ring and fasteners. The split disc body consists of two semi-circular split friction rings, an integral steel skeleton, pressure blocks, rivets and a slider; the split friction ring is riveted together through a pressure block, a rivet and an integral steel framework; the integral steel framework is fixedly connected to the disc hub and the pressure ring through fasteners. The split shaft-mounted brake disc of the present invention only needs to replace the split friction ring and rivets that wear to the limit in the later stage, and does not need to disassemble and replace the integral steel frame, hub, pressure ring and bolts and nuts. The integral steel The frame, disc hub, pressure ring and bolts and nuts are always connected together and fixed on the axle, which greatly reduces the operation and maintenance cost of the brake disc.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle braking devices, and in particular relates to a split shaft-mounted brake disc for rail vehicles. Background technique [0002] At present, there are mainly two forms of axle-mounted brake discs for rail vehicles: integral axle-mounted brake discs and split axle-mounted brake discs. [0003] The integral shaft-mounted brake disc is mainly composed of an integral disc body, disc hub, pressure ring and fasteners. When assembling the integral brake disc, align the bolt holes on the integral disc body, disc hub and pressure ring , the bolts are sequentially penetrated into the pressure ring bolt holes, the disc body bolt holes and the hub bolt holes and fixed with nuts, and finally the shaft-mounted brake disc is fixed on the axle by pressing. [0004] The difference between the split shaft-mounted brake disc and the integral shaft-mounted brake disc is the disc body. The disc body of the integr...
