ARRANGEMENT FOR POSITIONING A TRANSFORMER IN A RAIL VEHICLE

Abstract

An arrangement for positioning a transformer in a rail vehicle, where the rail vehicle has a transformer support which fastens the transformer at a predetermined position in the rail vehicle. The transformer support is arranged on an underframe of the rail vehicle. The transformer is connected to the transformer support via a sliding guide, wherein a positional change of the transformer relative to the underframe of the rail vehicle can be set by way of the sliding guide. The sliding guide is a hydrostatic sliding guide.

Claims

1-6. (canceled)

7. A positioning arrangement, comprising: a transformer; a rail vehicle having an underframe; a transformer support arranged on said underframe of said rail vehicle and configured to fasten said transformer at a predetermined position in said rail vehicle; a guide connecting said transformer to said transformer support, said guide being a hydrostatic or aerostatic sliding guide configured to enable a positional change of said transformer relative to said underframe of said rail vehicle to be set by way of said guide.

8. The arrangement according to claim 7, wherein said sliding guide is a linear guide.

9. The arrangement according to claim 8, wherein said sliding guide is a dovetail guide.

10. The arrangement according to claim 7, wherein: said transformer support includes a first sliding guide which allows a positional change of said transformer in a longitudinal direction of said rail vehicle, and/or said transformer support includes a second sliding guide which allows a positional change of said transformer transversely to a longitudinal direction of said rail vehicle.

11. The arrangement according to claim 7, wherein said transformer support has a sliding shoe connected to said sliding guide on one side and to a flange plate of said transformer on another side.

12. The arrangement according to claim 7, further comprising a welded bracket connecting said sliding guide of said transformer support to said underframe of said rail vehicle.

Description

[0024] The present invention will be described in more detail below by way of example with reference to drawings, in which:

[0025] FIG. 1 shows key parts of the arrangement according to the invention in a side illustration,

[0026] FIG. 2 to FIG. 6 show the arrangement according to the invention in different views.

[0027] FIG. 1 shows key parts of the arrangement according to the invention in a side illustration, with there here being shown by way of example only a displacement direction y for the position of the transformer TRAFO.

[0028] A rail vehicle SFZ or its underframe UNT is illustrated here by means of a constituent part, namely by means of a flange plate FPL which is used as a transformer transverse support.

[0029] The flange plate FPL defines a predetermined, rough position of the transformer TRAFO. The transformer TRAFO is connected to the flange plate FPL by way of a transformer support TFT.

[0030] The transformer support TFT includes a dovetail guide as sliding guide GF which is configured here as a hydrostatic sliding guide GF.

[0031] For the functionality of the hydrostatic sliding guide GF there are provided a central supply-line bore ZLB with oil connection and also a throttle DRL in the supply line.

[0032] The transformer support has a sliding shoe GS which is connected to the sliding guide GF on one side and to a fastening flange plate BFP of the transformer TRAFO on the other side.

[0033] The sliding guide GF of the transformer support TFT is connected by way of a welded bracket KONS to the flange plate FPL and thus to the underframe of the rail vehicle.

[0034] One embodiment-specific advantage lies in the fact that the transformer TRAFO lies in a defined and secure manner on the welded bracket KONS. This prevents the transformer TRAFO from falling down; it is thus as it were “captively” mounted.

[0035] FIG. 2 to FIG. 6 show the arrangement according to the invention in different views.

[0036] FIG. 2 additionally shows a stop ANS which can be flexibly adjusted on both sides and which here takes the form of plates which can be adjusted via threaded rods.

[0037] It is possible by means of the stop for the sliding guide GF (dovetail) to be fastened on the welded bracket KONS by a screw connection. The sliding guide GF is oriented exactly parallel by way of the screw connection in order to achieve a clean parallel guide.

[0038] To displace the transformer, the sliding guide GF is charged with oil pressure such that the transformer TRAFO can be displaced with minimized expenditure of force.

[0039] The displacement can be effected for example via further adjusting screws which are arranged on the end-side stop plates.
