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.

EOCC draft gear assemblies and cross keys for those assemblies are disclosed. In one embodiment, the cross key consists of a unitary generally T-shaped member having opposed lateral first and second end portions, a base portion formed with the first end portion, and a transition portion disposed between the base portion and the second end portion and formed with the base portion and the second end portion. The transition portion includes opposed longitudinal first and second transition faces. Each of the first and second transition faces has a shape that includes two or more radiuses of curvature.

A yoke for a railway car is provided with a coupler support protruding from a top wall of the yoke into an interior space in the yoke to contact the coupler shank when the coupler head is deflected downward to prevent the coupler from drooping after prolonged use.

A spacer arrangement (300) is configured to be fitted into a mounting compartment of a rail vehicle in order to bridge a gap distance between an innermost portion of a draft gear (200) and at least one support surface of the mounting compartment. The spacer arrangement (300) has two opposing side members (312; 313) configured to transfer buff forces exerted on the draft gear (200) to the at least one support surface of the mounting compartment. The spacer arrangement (300) is configured to contact a respective side wall of the mounting compartment, each of which side wall is perpendicular to the at least one support surface of the mounting compartment. The spacer arrangement (300) contains at least one pressure device (302) positioned between the two opposing side members (312; 313), which at least one pressure device (302) applies a pretension force between the two opposing side members (312; 313) to reduce the risk that these members buckle in case of an extreme buff force on the draft gear (200).
