Wheel set for rail vehicles

The invention relates to a wheel set for rail vehicles, especially for high speeds.

With conventional wheelsets, the two wheels are fixed, mil, connected to the wheelset shaft, which immediately rubbed the rags is stored. The wheelset bearings can be placed between the wheels (inner bearing) or outside in front of the wheels (outer bearing) be arranged. By the distance from the center of the rati Towards the center of the axle box, a die /// · moment arises tinter load, which builds up over this distance and in the MiLLc] part the wheelset shaft is constant. Since this OiegcmomenL the wheelset shaft is subject to changing loads, its corresponding dimensioning results in a considerable weight; their Unsprung mass contributes disadvantageously to increased wheel and track loads. With driven wheelsets a continuous axle requires a complex «; Design of the drive device, e.g. special Aehs'i.e-Lrlobo, Höh] woN narrow Lriohr, AntrJebo for JiI eic L roino I divii.

The invention is therefore based on the object of creating an insert in which, in particular, the unsprung masses are lower and simpler drive devices can be used. "

This object is achieved in that the Wheelset made up of two each receiving a wheel, both sides of the wheel each with a bearing provided Tragtoi .1 en and an intermediate piece connecting the ends of the supporting parts facing each other, ζ ^, Β «, a thin-walled spacer tube, Gearbox or a brake, there is »

The limitation that took place in the wheelset according to the invention the support parts on the area of each wheel advantageously result in a substantial reduction in weight and the unsprung masses and thus better running properties as well as less wear on the wheel and rail. This wheel set based on the modular principle is also advantageous due to the variable designs of the intermediate piece diverse, e.g. "for vehicles of different types or track width, can be used for running bogies or motor bogies or for different braking systems. Moreover is a uniform design of the part of the wheel-support-part-bearing and thus an economical production possible. In the end an individual wheel change is given, which improves maintenance and servicing.

For the vehicle-side connection of this wheel set is in development according to the invention provided that the two bearings of each support part are connected to each other by a fork-shaped, are connected to the vehicle body or to the bogie acting bracket.

For radial adjustments of the wheel sets in operation, a further feature of the invention provides that the two fork-shaped brackets of the wheel set connected to each other and in one on the vehicle body or on the bogie arranged fixed point are articulated in the sense of a radial adjustability of the wheelset.

A further development according to the invention is that the fork-shaped holder for receiving a on the corresponding Wheel engaging disc brake is formed. This design of the bracket is otherwise required Additional parts for the inclusion of the disc brake avoided, thereby further acting on the wheelset unsprung mass is reduced.

A more compact design of the wheelset and a direct power transmission in the area of its supporting parts is accordingly a final embodiment according to the invention achieved in that each bearing has one in its vertical axis arranged spring against the vehicle superstructure or structural components, e.g. frame parts eiiios rotary gears, is supported.

An embodiment of the invention is in Drawing shown and is described in more detail below. It show in schematic representation

Fig. 1 shows a wheel set in view, cut in the bearings,

Figc 2 shows the plan of Fig. 1,

3 shows a linkage of the wheelset according to FIGS. 3 and 2, also in plan.

According to FIGS. 1 to 3, a wheel set 1 has two wheels 2 aiii ′, which are each firmly connected to a support part 4. The bearings arranged at the ends of each supporting part k are connected to one another by a fork-shaped bracket Γ> which act on the vehicle body or on the bogie. A releasable intermediate piece 5 connects the two support parts k to one another. The bearings 3 can, not shown here, be supported against the vehicle body or components supporting it via springs arranged in their vertical axes.

In Fig. 2, in addition to Fig. 1, the arrangement of disk brakes 8, which are received by the brackets 6.
