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.
