    Abstract: Buffer, in particular for a rail vehicle, includes a buffer sleeve, forming a pressure chamber, a jointed head securable to this sleeve on the face side by a connection flange, and a buffer piston rod, mounted opposite in the buffer sleeve to be displaceable longitudinally. The jointed head is connectable in a jointed manner to the rail vehicle, while the buffer piston rod is preferably connectable to a coupling head. The connection flange has an outer thread on its outer casing, screwed to an inner thread in a hole of the buffer sleeve to form a releasable connection of the jointed head with the buffer sleeve. The connection flange preferably has on the front side a centering tip element before the outer thread, which is slid or pressed essentially free of play into the hole of the buffer sleeve.

  • Publication number: 20220144323
    Abstract: 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.

  • Patent number: 11059501
    Abstract: 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.
