Traction Couplings And Rail Vehicles

4. However, the coupling play, in particular the coupling joint play, is disadvantageous with regard to the response to load changes from the driving dynamics and is manifested by jerky movements that are clearly noticeable in powered vehicles. Traditionally larger coupler clearances result in higher load change forces during approach and extension of individual rail cars, which require higher fatigue strength of the coupler components.

5. Couplings with type 10 couplings (Schaffenberg couplings, design with funnels and cones arranged on end plates) as the invention particularly relates to in the field of freight transport, for example in intermodal transport, i.e. Used in wagon cars, the wagon cars are designed as container cars or trough cars for transporting trucks and/or semi-trailers. The train weight of this group of cars is significantly lower than the group of cars used to transport bulk materials or steel.

6. The technical problem to be solved by the present invention is to provide a traction coupling which bears less load, especially when used in a freight car group, so as to prolong the service life and/or reduce the requirements for combating fatigue. When used in a train set, the load variation forces when the individual rail cars are approached and stretched are reduced and vibration conditions are improved overall.
