A coupler assembly, arranged at a front end of a vehicle head of a rail vehicle, includes: a coupler mounting base fixed to the vehicle head; a coupler fixedly mounted to the coupler mounting base, and a supporting component provided at each of two sides of the coupler mounting base. The supporting component has a guiding slide way inclined longitudinally, a front end of the guiding slide way is higher than a rear end of the guiding slide way; a sliding component is fixedly provided at each of the two sides of the coupler mounting base, and the sliding component slidably cooperates with the guiding slide way at a respective side; and the coupler assembly is configured such that in an initial state, the coupler mounting base is fixedly connected to the supporting component, and the sliding component is located at a front end of the guiding slide way.

Linkage device for a couplings of railway vehicles, the coupling head of which is connected to a drawbar linked to a steering pivot of the railway vehicle, which drawbar is provided with spring elements sitting on it in order to dampen compressive and tensile force that arise, e.g., when coupling the railway vehicle. The spring elements are fastened to a plate that can be rotated about an axis of rotation of the steering pivot. In this way, they are also deflected when the coupling is deflected so that the compressive and tensile forces acting on the latter also act upon its entire surface evenly, even when the coupling is deflected. The linkage device is also provided with overload protection.

A railroad car coupling system including a draft sill with front and rear stops, a coupler along with an energy management assembly for receiving and dissipating external forces experienced by the coupler. A yoke also forms part of the coupling system and is operably coupled to the coupler. The yoke includes top and bottom walls which each include two forward facing stops. A follower is mounted substantially between the top and bottom walls of the yoke for receiving forces experienced by the coupler. The follower is configured with two laterally spaced vertical extensions disposed toward opposed upper corners of the follower and two laterally spaced vertical extensions disposed toward opposed lower corners of the follower. Forward facing surfaces on the follower extensions arc arranged in generally coplanar relationship relative to each other. Rearward facing surfaces on the follower extensions are arranged in generally coplanar relationship with each other and operably engage with the forward facing stops on the yoke to enhance the distribution of forces when the follower engages the front stops on the center sill when the coupling system is in a full draft condition.
