A coupling box of a rail vehicle, including a fixed portion fixedly mounted on a vehicle body and a movable portion connecting to a coupler and draft gear; the movable portion is connected to an inner end of the fixed portion by means of a constant-force connecting member, the constant-force connecting member is broken when the coupler and draft gear pushes the movable portion to move inwardly at the time of a collision, so that the movable portion and the fixed portion are able to be separated from each other.

An energy dissipation device is shown in connection with its implementation in train couplers. The energy dissipation device comprises axially compressible, irreversibly deforming steel elements arranged in a housing and axially pre-tensioned between a compression means and a counter-pressure means. In case of an impact, the compression means is moving in sliding contact with the inside wall of the housing to provide axial compression of the energy absorbing elements while preserving the integrity of the housing.

A snow protection assembly is provided for a coupling region of a rail vehicle. The rail vehicle has, on an end face, a recess which protects against snow, in which recess a coupling of the rail vehicle is arranged. A fixed housing partially extends around the recess. The housing has an opening in the direction of travel of the rail vehicle, from which opening the coupling partially protrudes to enable a process of coupling to an additional rail vehicle. The opening of the fixed housing is peripherally fixedly connected to a first sealing element. A second sealing element is rotatably connected to the coupling, and the second sealing element partially extends around the coupling. The two sealing elements partially overlap in the region of the opening. The two sealing elements are coupled to one another by pressure to protect the opening against the ingress of snow.
