Split type structure train wheel

Abstract

The invention belongs to the technical field of train wheels, and particularly relates to a split type structure train wheel. The train wheel comprises a rim, inner spokes, inner incline planes, innerlightening holes, inner curve surfaces, an inner hub, outer spokes, outer incline planes, outer lightening holes, outer curve surfaces, an outer hub, bolts and bosses. The rim is shaped by integratedforging and pressing, the inner ring of the rim is provided with the bosses, and the inner incline planes and the outer incline planes which are symmetrically arranged on the two sides of the bosseshave incline angles of eight degrees relative to a horizontal plane; the outer edges of the inner strokes and the outer strokes are processed to be provided with incline angles of eight degrees relative to the horizontal plane, and the inner and outer strokes are matched with the rim and fixedly connected with the rim through bolts. According to the split type structure train wheel, the wheel is hollow inside, the lightening holes are uniformly distributed to facilitate braking and heat dissipating, and compared with integrated type steel structure wheels of the same type, the weight of the split type train wheel is reduced by 19.4%; under the same subjected force and operation state, the stress of the novel train wheel is reduced approximately by 14.6%.

Description

technical field [0001] The invention relates to the technical field of wheels, in particular to a train wheel with split structure. Background technique [0002] Train wheels have a variety of shapes and structures, and different shapes, structures and materials can produce different effects to achieve a special purpose or solve a specific problem. Existing train wheels have integral type and split type (tire wheel) structures. The overall structure is relatively simple and easy to manufacture and process. Split wheels can be divided into cast steel spoke wheels, rolled steel spoke wheels, and wheels with cast steel spoke hubs. At present, most of China uses integral wheels and a small number of split wheels. The current integral wheel structure is stable, but the weight is relatively large; the split wheel structure is relatively complicated and needs to be assembled later, but it has relatively better special performance, and the split casting structure is efficient.

The current integral wheel structure is stable, but the weight is relatively large; the split wheel structure is relatively complicated and needs to be assembled later, but it has better special performance, and the split casting structure is efficient

[0003] For example, the Chinese patent application number CN201320379843.8 discloses a new type of train wheel, which includes a web, a brake disc mounting surface, a drive pin mounting surface, a brake disc mounting hole, a drive pin mounting hole, a rim and a hub. The rim and hub are respectively arranged on both sides of the web, the web is provided with a brake disc mounting surface and a drive pin mounting surface, the brake disc mounting surface is provided with a brake disc mounting hole, and the transmission pin mounting surface is provided with a Pin mounting holes, the brake disc mounting surface is set on the rim side, and the transmission pin mounting surface is set on the wheel hub side. Its structure is stable but its quality is relatively heavy, which will generate greater stress and energy loss during the train’s travel.

[0004] The mass of split wheels in the prior art is relatively small, but the complexity of the structure makes the forging process and installation process more complicated. Therefore, the present invention aims to provide a train wheel with split structure, the main function is to ensure the basic performance Simplify the structure, simplify the processing and manufacturing, and reduce the weight of the wheel
