Traction/pushing device for central buffer couplings of rail vehicles has two energy absorption systems switched in series and located in coupling housing

摘要

The device has a coupling arm with head born elastically pref. via a stabilizer joint. The joint transmits traction and pressure forces into the bogie via an outer housing (10) and energy absorption systems (9,11). The systems are switched in series and are located in the housing. One and/or both systems have an irreversibly deformable deformation element (23), e.g. a mechanical shock absorption part. This is e.g. a tube, which is deformed by a nozzle (25) or a pressure ring (21), after a set pressure and/or traction load limit on shear ring (20) and/or pin has been exceeded.
