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

1 .- 14 . (canceled)

15 . A chassis frame for a rail vehicle, comprising:
at least one drive unit fastened to the chassis frame via at least one elongated fastener disposed transversely with respect to a direction of travel; and mounting brackets fixedly connected to the chassis frame; wherein said least one elongated fastener one of (i) projects into the chassis frame and (ii) is guided through mounting brackets fixedly connected to the chassis frame, and projects into a space located above or below the chassis frame.

16 . The chassis frame as claimed in claim 15 , wherein the at least elongated one fastener is disposed so as to penetrate a longitudinal member of the chassis frame.

17 . The chassis frame as claimed in claim 15 , wherein the at least elongated one fastener is disposed so as to penetrate a sidewall of a longitudinal member of the chassis frame.

18 . The chassis frame as claimed in claim 15 , wherein at least one mounting bracket is arranged on a longitudinal member of the chassis frame.

19 . The chassis frame as claimed in claim 16 , wherein at least one mounting bracket is arranged on a longitudinal member of the chassis frame.

20 . The chassis frame as claimed in claim 17 , wherein at least one mounting bracket is arranged on a longitudinal member of the chassis frame.

21 . The chassis frame as claimed in claim 15 , wherein all elongated fasteners disposed transversely with respect to the direction of travel are guided through the mounting brackets and project into the space above or below the chassis frame.

22 . The chassis frame as claimed in claim 15 , wherein the drive unit is mounted on the chassis frame via at least one elastic element acting in conjunction with the at least one fastener.

23 . The chassis frame as claimed in claim 22 , wherein the at least one elastic element is fixedly connected to the drive unit.

24 . The chassis frame as claimed in claim 22 , wherein the at least one elastic element is fixedly connected to the chassis frame.

25 . The chassis frame as claimed in claim 22 , wherein the at least one elastic element forms part of an inner bushing which is fixedly connected to one of (i) the chassis frame and (ii) the drive unit, and a respective other part is retained in the inner bushing via the at least one elongated fastener.

26 . The chassis frame as claimed in claim 23 , wherein the at least one elastic element forms part of an inner bushing which is fixedly connected to one of (i) the chassis frame and (ii) the drive unit, and a respective other part is retained in the inner bushing via the at least one elongated fastener.

26 . The chassis frame as claimed in claim 24 , wherein the at least one elastic element forms part of an inner bushing which is fixedly connected to one of (i) the chassis frame and (ii) the drive unit, and a respective other part is retained in the inner bushing via the at least one elongated fastener.

27 . The chassis frame as claimed in claim 15 , wherein the at least one elongated fastener comprises a bolt or a screw.

28 . The chassis frame as claimed in claim 25 , wherein the at least one elongated fastener is pressed into the other part.

29 . The chassis frame as claimed in claim 28 , wherein the bolt is pressed into the other part.

30 . The chassis frame as claimed in claim 15 , wherein the drive unit is disposed in the direction of travel.

31 . The chassis frame as claimed in claim 31 , wherein the drive unit is disposed laterally outside the at least one longitudinal member.

32 . The chassis frame as claimed in claim 15 , wherein the drive unit is disposed transversely with respect to the direction of travel between longitudinal members.
