An integrated self-supporting and deformation-resistant modular driver's cabin structure for mounting to the front end of a rail vehicle body and for providing a driver space and a windshield opening, is composed of a composite sandwich structure with a single, common, continuous outer skin layer, a single, common, continuous inner skin layer and an internal structure wholly covered with and bonded to the inner and outer skin layers, the internal structure comprising a plurality of core elements. The driver's cabin structure comprises at least: side pillars each having a lower end and an upper end, and an undercarriage structure at the lower end of each of the side pillars. The fiber-reinforced sandwich located in the side pillars is provided with several layers of fibers oriented to provide a high bending stiffness. The fiber-reinforced sandwich of the undercarriage structure is such to transfer static and crash loads without flexural buckling.

Lightweight compound cab structure for a rail vehicle

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.
