Coupler device for a coupling, in particular of a rail vehicle, is provided with a drawbar with spring elements mounted thereon in order to dampen the tension and pressure forces incurred, with a plate arranged between these, and a support flange secured to the rail vehicle. The plate bears the drawbar and is held on the support flange and connected at its outer circumference in each case with a carrier disk, each in an opening of the support flange, by overload elements arranged adjacent to one another. The overload elements are sheared off in the event of an overload in the pressure or tension direction of the drawbar. Accordingly, a secure connection is formed between the support flange and the plate, which, in the event of a crash or an overload, can be detached in a functionally reliable manner, but which in normal operation ensures a perfect coupling linkage.

A regenerative energy absorption device for damping forces which occur during operation of a track-guided vehicle, in particular tensile, impact and/or torsional forces, wherein the energy absorption device includes at least one spring device with an elastomer body which is designed so as to at least partially deform elastically when forces are introduced into the energy absorption device, wherein the elastomer body is at least partially formed from an electrically conductive material, the specific electrical resistance of which varies under tensile and/or compressive load, and wherein the energy absorption device is allocated a resistance sensor device for detecting electrical conductivity or electrical resistance of the electrically conductive material.

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.

The invention relates to a bearing block assembly for hinging of a coupling rod to a carriage body. The bearing block assembly includes a bearing shell unit and a bearing block with a flange for connecting the bearing block assembly to the carriage body and has an open bearing shell receiving region for at least partial reception of the bearing shell unit. The bearing block assembly has at least one guide extending in a longitudinal direction over at least a section of the extension of the bearing block. The bearing shell unit connects to the bearing block via at least one tear-off element and/or at least one shear-off element and is movably guided on the at least one guide in a longitudinal direction relative to same when the connecting element is actuated, thereby releasing the connection between the bearing shell unit and the bearing block.

Articulated connectors are attached to and extend from center sills of adjacent car units of a multi-unit railroad freight car, connecting the car units to each other and to a shared truck. The center sill of each of the car units includes a top member that is of increased thickness at the outer end of the center sill. A weld extending along a shoulder that extends around the main body of s portion of the articulated connector attaches the articulated connector portion to the outer end of the center sill with ample strength to carry draft and buff train loads as well as the weight of the car unit and its lading, without the need for weld joints inside the center sill.
