A rail vehicle has a central buffer coupling with a coupling head, a rod-shaped coupling shaft and a spring mechanism. The coupling head connects to a coupling head of another rail vehicle and is connected to the coupling shaft. The shaft is inserted into the spring mechanism and is mounted and fastened therein such that, during operation of the rail vehicle, impact forces or tensile forces acting on the coupling head are resiliently absorbed by the spring mechanism and transferred to a wagon body. A support is coupled to the coupling shaft and is connected to the wagon body. A collision element is arranged between the support and the wagon body. The collision element has a deformation region configured such that kinetic energy, transferred to the collision element via the coupling shaft and via the coupled support due to a collision, irreversibly deforms the deformation region in a predetermined manner.

A system of a side skirt for a car of a multi-car vehicle and a side skirt support, the side skirt configured to cover a space below the underframe of the car from a side, and having a coupler side edge that forms a side of the side skirt and arranged next to a coupler head of the car, the side skirt support suitable to attach the side skirt to the underframe of the car, the side skirt support having a bar with a first joint suitable to be attached to the underframe to allow rotation relative to the underframe, the bar being attached to a part of the side skirt via a second joint that allows part of the side skirt to rotate relative to the bar, the side skirt support having a rotation controller that limits the rotation that the part of the side skirt attached to the bar can perform relative to the bar, whereby the part attached to the bar can rotate into an end position, but cannot rotate beyond that end position.

A coupling support for a central buffer coupling of a rail vehicle includes first and second holding plates to be secured to the body of the rail vehicle. The coupling support has a base plate and a transverse bar disposed between the holding plates. The transverse bar is resiliently coupled to the base plate and is disposed above the base plate. First and second pivot levers are disposed on the base plate such that the pivot location of each pivot lever is disposed below the transverse bar, and the pivot locations are connected to the base plate. Each upper portion of the pivot levers is connected to the transverse bar by an articulated connection such that a movement of the transverse bar away from the base plate is restricted by the articulated connections and a movement of the transverse bar towards the base is allowed by the articulated connections.

The present invention relates to a bearing block for articulating a coupling rod to a car body of a track-guided vehicle, particularly a railway vehicle. A modular design is provided so as to be able to easily and yet effectively adapt the bearing block to different applications. To this end, the bearing block comprises a first crosspiece having a bearing shell situated in a first horizontal plane as well as a second crosspiece having a bearing shell situated in a second horizontal plane. The two bearing shells each have a respective mount for a vertically extending (common) pivot bolt or for a pivot pin allocated to the respective bearing shell. The modular design of the bearing block is particularly realized by the first and second crosspiece being implemented as separate structural components independently connectable to the car body of the track-guided vehicle.
