Energy dissipating device and connection device comprising such an energy dissipating device
An energy dissipating device includes a guide defining a guide surface having a curved cross-section. A deformer is slideably supported by the guide surface of the guide in a compression stroke direction of the device. A stopper is fixedly attached to the device and arranged at a distance from the deformer in the compression stroke direction. An energy dissipating member is arranged between the stopper and the deformer in the compression stroke direction, and includes a first end configured to engage with the stopper and a second end configured to engage with the deformer in response to a force thereon in the compression stroke direction.

RAILCAR ENERGY ABSORPTION SYSTEM AND RELATED METHOD FOR ABSORBING ENERGY ON A RAILCAR
An energy absorption system for a railcar having an elongated sill with front and rear stops defining a pocket therebetween. To facilitate use of known railcar structures, the energy absorption system can be used in combination with a railcar also having a sill with center stops disposed between the front and rear stops. A coupler having a head portion and a shank portion is arranged in operable combination with the energy absorption system. The energy absorption system also includes a first cushioning assembly positioned in the sill pocket. A first follower is urged toward and engageable with the front stops under the influence of the first cushioning assembly and is operably engageable with a free end of the shank portion of the coupler. A second cushioning assembly is positioned in generally axial alignment with first cushioning assembly. A second follower is positioned and normally urged by the energy absorption system toward and configured to engage with the center stops. An axially elongated yoke encompasses the first and second cushioning assemblies, terminates in an open forward end, and is coupled to the shank portion of the coupler. The first and second cushioning assemblies act in series relative to each other to absorb and cushion impact forces directed against them when the energy absorption system operates in a buff direction. Advantageously, the second follower acts in concert with the center stops and the second cushioning assembly to minimize excessive system cycles while better dissipating train action energy when the energy absorption system operates in a draft direction.

Traction-impact device and force transmission unit having such a traction-impact device
A traction-impact device including two force transmission elements which extend along a longitudinal axis and which are connected to each other in a force-transmitting manner and an irreversible energy absorption device that includes at least one energy absorption element which at least partially or in regions, preferably completely, includes a fiber composite material. The irreversible energy absorption device is at least partially received by a first of the two force transmission elements. This first force transmission element includes a nozzle portion. The irreversible energy absorption element is arranged in such a manner with respect to the nozzle portion and the other second force transmission element that, when an impact force which exceeds the maximum permissible impact force is introduced into the traction-impact device, the irreversible energy absorption element is pressed through the nozzle portion with at least partial, preferably complete defibration of the regions formed from fiber composite material.
