Abstract

A chassis frame for a rail vehicle which includes at least one drive unit fastened to the chassis frame via at least one elongated fastener, wherein the at least one fastener is arranged transversely with respect to the direction of travel and protrudes into the chassis frame or is guided through brackets which are fixedly connected to the chassis frame and protrudes into a space above or below the chassis frame in order to reduce the weight for the bearing of the drive unit and to facilitate mounting of the drive unit.

First claim

The invention claimed is:

1. A chassis frame for a rail vehicle, comprising:
at least one motor fastened to the chassis frame by at least one elongated fastener of elongated fasteners disposed transversely with respect to a direction of travel of the chassis frame;
transverse members extending between the elongated fasteners; and
mounting brackets fixedly connected to the chassis frame on top and at an outer longitudinally extending edge of the chassis frame;
wherein said at least one elongated fastener is guided through at least one mounting bracket of the mounting brackets which is fixedly connected to the chassis frame, and projects into a space located above;
wherein the at least one elongated fastener comprises a screw which extends horizontally and in parallel to a central transverse axis of the chassis frame;
wherein the chassis frame is defined by two longitudinal members extending from a region of the chassis frame which includes the transverse members in a forward and rearward direction with respect to the direction of travel of the chassis frame;
wherein the chassis frame supports the at least one motor with two configurations, each configuration being dependent on an orientation of the at least one motor, a first configuration of the two configurations having the at least one motor extending across a transverse center line of the chassis frame and a second configuration of the two configurations having the motor extending across a longitudinal center line of the chassis frame;
wherein the transverse members form part of the chassis frame and interconnect the two longitudinal members; and
wherein the two longitudinal members form a portion of the chassis frame to which the mounting brackets are fixedly connected.

2. The chassis frame as claimed in claim 1 , wherein another at least elongated one fastener is disposed so as to penetrate one of the longitudinal members of the chassis frame.

3. The chassis frame as claimed in claim 1 , wherein another at least elongated one fastener is disposed so as to penetrate a sidewall of one of the longitudinal members of the chassis frame.

4. The chassis frame as claimed in claim 1 , wherein the at least one mounting bracket of the mounting brackets is arranged on one of the longitudinal members of the chassis frame.

5. The chassis frame as claimed in claim 2 , wherein the at least one mounting bracket of the mounting brackets is arranged on one of the longitudinal members of the chassis frame.

6. The chassis frame as claimed in claim 3 , wherein the at least one mounting bracket of the mounting brackets is arranged on one of the longitudinal members of the chassis frame.

7. The chassis frame as claimed in claim 1 , wherein the at least one motor is mounted on the chassis frame by at least one elastic element acting in conjunction with the at least one fastener.

8. The chassis frame as claimed in claim 7 , wherein the at least one elastic element is fixedly connected to the at least motor.

9. The chassis frame as claimed in claim 7 , wherein the at least one elastic element is fixedly connected to the chassis frame.

10. The chassis frame as claimed in claim 7 , wherein the at least one elastic element is provided between two parts of a mount half of an elastic motor mount and overlies the two parts of the mount half in a planar manner.

11. The chassis frame as claimed in claim 8 , wherein the at least one elastic element is provided between two parts of a mount half of an elastic motor mount and overlies the two parts of the mount half in a planar manner.

12. The chassis frame as claimed in claim 1 , wherein the at least one motor is disposed in the direction of travel of the chassis frame.

13. The chassis frame as claimed in claim 1 , wherein the at least one motor is disposed laterally outside the at least one longitudinal member.

14. The chassis frame as claimed in claim 1 , wherein the at least one motor is disposed transversely with respect to the direction of travel between longitudinal members.

15. The chassis frame as claimed in claim 9 , wherein the at least one elastic element is provided between two parts of a mount half of an elastic motor mount and overlies the two parts of the mount half in a planar manner.

16. The chassis frame as claimed in claim 1 , wherein the transverse members are spaced apart in the longitudinal direction.

17. A chassis frame for a rail vehicle, comprising:
at least one motor fastened to the chassis frame by at least one elongated fastener of elongated fasteners disposed transversely with respect to a direction of travel of the chassis frame;
transverse members extending between the elongated fasteners; and
mounting brackets fixedly connected to the chassis frame on top and at an outer longitudinally extending edge of the chassis frame;
wherein said at least one elongated fastener is guided through at least one mounting bracket of the mounting brackets fixedly connected to the chassis frame, and projects into a space located above; and
wherein the at least one elongated fastener comprises a screw which extends horizontally and in parallel to a central transverse axis of the chassis frame;
wherein the at least one elongated fastener includes at least two elongated fasteners extending through different portions of the frame or different ones of the mounting brackets in a manner such that the at least two fasteners extend substantially parallel with each other along the direction of travel or along a transverse axis depending on whether the at least one motor is mounted internally or externally with respect to the chassis frame;
wherein the chassis frame is defined by two longitudinal members extending from a region of the chassis frame which includes the transverse members in a forward and rearward direction with respect to the direction of travel of the chassis frame of the rail vehicle;
wherein the chassis frame supports the at least one motor with two configurations, each configuration being dependent on an orientation of the at least one motor, a first configuration of the two configurations having the at least one motor extending across a transverse center line of the chassis frame and a second configuration of the two configurations having the motor extending across a longitudinal center line of the chassis frame;
wherein the transverse members form part of the chassis frame and interconnect the two longitudinal members; and
wherein the two longitudinal members form a portion of the chassis frame to which the mounting brackets are fixedly connected.

18. The chassis frame as claimed in claim 17 , wherein the transverse members are spaced apart in the longitudinal direction.
