Abstract
A chassis for rail vehicles, particularly with inside-supported wheelsets, wherein the drive unit is elastically supported transversely to the travel direction via spring devices within the chassis frame, where the vibrational behavior is optimized and the space available for the drive unit is enlarged because the spring devices are supported directly on the housing of the bearing of the wheelset.
Claims16
A chassis for rail vehicles in which wheelsets with a drive unit are supported in a chassis frame;
- wherein at least parts of the drive unit are moveably elastically supported transversely to a travel direction via spring devices which permit lateral movement of the drive unit perpendicularly to the travel direction and in the vertical direction;
- and
- wherein each of the spring devices is fastened to a housing of at least one bearing of the wheelsets.
A chassis for rail vehicles in which wheelsets with a drive unit are supported in a chassis frame;
- wherein at least parts of the drive unit are moveably elastically supported transversely to a travel direction via spring devices comprising a vertical support fastened to a housing of the wheel bearing, upon which elastic elements are arranged, and against which flange-type lugs connected to the drive unit laterally abut;
- and
- wherein each of the spring devices is fastened to a housing of at least one bearing of the wheelsets;
- wherein the vertical support comprises a steel sleeve fastened to a support surface of the housing of the at least one bearing and the flange-type lugs have a hole for receiving the steel sleeve and stop surfaces in a region of the hole on the bottom and top sides;
- and
- wherein the flange-type lugs are clamped in the region of the hole between two annular elements comprising elastic material and these elastic annular elements rest laterally on the stop surfaces, so that the drive unit can implement elastically lateral transverse and vertical movements via the flange-type lugs.
