  • Patent number: 10000219
    Abstract: A rail vehicle has a bogie which rolls on a track in a direction of travel, a vehicle structure which is supported on the bogie, a rigid carrying structure which is arranged on the end side of the rail vehicle, and an end-side coupling opening through which a coupling extends for coupling further rail vehicles. A coupling securing device secures the coupling to the rail vehicle. The coupling securing device has reversible securing elements which permit a reversible lifting movement counter to the direction of travel to such an extent that the coupling is retracted completely into the supporting structure. As a result of the retraction of the coupling into the cage-like carrying structure it no longer influences the crash behavior.

  • Patent number: 5159882
    Abstract: An improved railway car underbody support structure and method for economically constructing same. The structure includes a center sill assembly having a pair of vertically disposed side plates spaced equidistant from the longitudinal center line of the car body and extending from a coupler longitudinally inboard to a wheeled truck assembly. The truck assembly carries two laterally spaced side bearing members for bearing the load of the car body during lateral tilting of the car body. One of the improved features is a unitary metal member cut from an economically patterned metal plate. The unitary members, which are themselves free of any weld lines which may crack under the extreme loads exerted on railway cars, are welded to the underside edge of a respective side plate and welded together beneath the center line of the car body.

  • Patent number: 4802420
    Abstract: This invention relates to centre beam freight cars. The purpose of these freight cars is to carry large, bulky freight which does not require much protection from the elements. Thus, any freight car must have wide utility and sufficient rigidity but a tare mass which does not constitute a high proportion of the fully laden mass of the freight car. The prior art freight cars suffer from a high tare mass proportion in order to provide sufficient rigidity. In this invention, a freight car is provided with a centre beam structure in the form of a vertical truss having a horizontal truss mounted on the top of it. Either of the trusses, or both, are in the form of an open truss. This centre beam structure provides a freight car which has adequate resistance to normal lateral and compressive stresses but has a relatively low tare mass in relation to its fully laden mass.
