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 track wheel 1 shown in includes a wheel body 2 , an elastic body 3 , a tire 4 , a tensioning ring 5 , a plurality of fixing bolts 6 serving as tensioning means, and a support member 7 .

[0041] The wheel body 2 is forged in one piece from a proven aluminium material in a known manner. It has a central hub opening 8 through which the axis of rotation of the track wheel 1 extends. Around the circumference of the wheel body 2 is a circumferential shoulder 9 which extends approximately in the range of half the width B of the wheel body 2 and whose perimeter face 10 is in the form of a tapered ring towards the centre of the width of the wheel body 2 Shaped in 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 . Starting from the end face 11 , a receptacle 13 , which is formed in the manner of an annular gro...

Abstract

The invention relates to a multi-part rail wheel with a tire (4), a wheel body (2), an elastomer (3) arranged between the tire (4) and the wheel body (2), through which The elastic body supports the tire (4) on the wheel body (2) and has at least one tensioning element which is attached to the wheel body (2) from the end side, by means of which the elastic body (3) is mounted on the wheel body (2). The tensioning device (6) on the wheel body (2) is tensioned relative to the wheel body (2) and the tire (4), wherein the wheel body (2) is made of light metal material in at least one area, and the tensioning device ( 6) Act relative to this area. The multi-part rail wheel according to the invention, in which the spring element is arranged, can be assembled in a simple manner and can be dismantled by means of simple tools, while ensuring reliable tensioning of the cooperating parts. This is achieved by providing at least one bearing element (7, 31) as a bearing on the end side (11) of the wheel body (2) axially opposite the tensioning element (5), the tensioning device (6). ) is mounted on the support, and the support is made of a material with a strength greater than that of the light metal material of the wheel body (2).

Description

technical field [0001] The invention relates to a multi-part rail wheel with a tire, a wheel body and an elastic body arranged between the tire and the wheel body, by means of which the tire is supported on the wheel body, and has an end-side mounting to the wheel body. A tensioning element on the wheel body, by means of which the elastic body is tensioned with respect to the wheel body and the tire by means of a tensioning device mounted on the wheel body, wherein the wheel body is held at least in the region where the tensioning device acts. Made of light metal material. Background technique [0002] Track wheels of this type are known, for example, from EP 0 733 493 B1. The known track wheel consists of steel forged or rolled tires and a wheel body made of aluminum alloy or other light metal material, the wheel body comprising a hub by which the track wheel is supported in use on the axle of the corresponding rail vehicle. superior. Notches are provided in the tire and...
