Problems solved by technology

The disadvantage of these measures, however, is that the clamping length of the bolt required to secure the threaded connection is reduced and, when using an additional threaded insert, a larger diameter is required
This in turn leads to poorer strength properties around the area of ​​the wheel body respectively accommodating the thread
Also, in the case of screw-in sleeves, the possibility of securing against loosening, especially by glued bolts, is limited
At the same time, there is a risk that when the fixing bolt falls off, the screw-in sleeve is also screwed out of the wheel body

Embodiment Construction

[0040] figure 1 and 2 The rail wheel 1 shown in includes a wheel body 2, an elastic body 3, a tire 4, a tightening ring 5, a plurality of fixing bolts 6 and a support member 7 used as a tightening device.

[0041] The wheel body 2 is forged in one piece in a known manner from a proven aluminum material. It has a central hub opening 8 through which the rotational axis of the rail wheel 1 extends. Around the circumference of the wheel body 2 there is a peripheral shoulder 9 which extends approximately over half the width B of the wheel body 2 and whose peripheral surface 10 is in the form of a conical ring in the direction of the center of the width of the wheel body 2 Shaped with a sloping descent.

[0042] At the axially outer edge of the peripheral shoulder 9 , which corresponds to the end face 11 of the wheel body 2 , the peripheral shoulder carries a surrounding beam 12 . A receptacle 13 formed in the manner of an annular groove around the axis of rotation D is formed s...

Abstract

The present invention relates to a multi-part rail wheel having a wheel tyre (4), having a wheel body (2), having an elastic body (3) which is arranged between the wheel tyre (4) and the wheel body (2) and by means of which the wheel tyre (4) is supported on the wheel body (2), and having at least one bracing element which is mounted onto the wheel body (2) from one face side and by means of whichthe elastic body (3) is braced against the wheel body (2) and the wheel tyre (4) by pressing means (6) which act on the wheel body (2), wherein the wheel body (2) is composed of a light metal material at least in the region against which the bracing means (6) acts. The multi-part, inherently elastically sprung rail wheel ensures reliable bracing of the interacting components whilst being easy toassemble and disassemble using simple means. This is achieved in that, on that face side (11) of the wheel body (2) which is situated axially opposite the bracing element (5), at least one counterbearing element (7, 31) is provided as a counterbearing on which the bracing means (6) act, which counterbearing element is composed of a material which has a higher strength than the light metal materialof the wheel body (2).

Description

technical field [0001] The invention relates to a multi-part track wheel, which has a tire, a wheel body and an elastic body arranged between the tire and the wheel body, by which the tire is supported on the wheel body, and has a tensioning element on the wheel body, by means of which the elastic body is tensioned relative to the wheel body and the tire by means of a tensioning device mounted on the wheel body, wherein the wheel body is at least in the area where the tensioning device acts by Made of light metal material. Background technique [0002] Such track wheels are known, for example, from EP 0 733 493 B1. The known rail wheel consists of a steel forged or rolled tire and a wheel body made of aluminum alloy or other light metal material, the wheel body containing the hub, by means of which the rail wheel is supported in use on the axle of the corresponding rail vehicle superior. Indentations are provided in the tire and grooves are provided in the rim for placing...
