Abstract
The invention relates to a railway vehicle with a self-supporting car body having a floor and a roof as well as side walls which present windows and access areas. The side walls are each made of a frame which is rigidly connected to the floor and presents side wall elements. The car body skin elements are configured in a supporting manner and fixed to frame elements ( ) by friction so as to form a ribbed plate support structure ( ). The car body skin elements comprise an integrated intermediate layer ( ) having vibration-damping properties. Frictional adhesive joints ( ) or frictional screw or rivet joints ( ) between the frame elements ( ) and supporting car body skin elements can be provided for. The supporting car body skin elements are configured as supporting sandwich elements ( ) which consist of an outer layer ( ), an inner layer ( ) and an intermediate layer ( ) which has heat- and/or sound-insulating and vibration-damping properties and maintains the outer and inner layer at a distance from each other.
