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.
Claims18
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.
