摘要： A railcar end unit is operable to be mounted in a center sill between buff and draft sill stops. The buff and draft end bodies are configured to be shiftably mounted relative to the center sill to engage the respective sill stops and to shift axially relative to one another along a unit axis. The end unit includes a buff spring pack operably mounted between the end bodies and compressible along the unit axis from a neutral condition to a compressed condition.

摘要： 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.

摘要： A draft gear assembly for use with railcars having coupler members is provided. The draft gear assembly has front and back ends and comprises a yoke, a coupler follower, a front resilient member, an intermediate stop member, and a back resilient member. The yoke has a back wall, a top wall extending from the back wall toward the front end of the draft gear assembly, and a bottom wall extending from the back wall toward the front end of the draft gear assembly. The coupler follower is positioned between the butt end of the coupler shank and the front end of the draft gear assembly. The front resilient member is positioned between the coupler follower and the intermediate stop member. The back resilient member is positioned between the intermediate stop member and the yoke back wall. The front and back resilient members are compressible.

摘要： The draft gear includes: friction elements; coil spring elements; and elastomer elements. With respect to the friction elements, three groups of friction surfaces are defined each of which create a specific angle with respect to a centerline passing down the center of the draft gear. The elastomer elements are interconnected multiple segmented columns having specific heights and occupying particular volumes with respect to the coil spring elements. Particular hardness and number of segments of the elastomer elements are also defined.

摘要： To avoid, after excessive shocks in the underframe in the forestructure and at the coupling of a traction/thrust pivoted joint or device of a vehicle, deformations of a central buffer coupling at the underframe of the vehicle is proposed. Arranged between the carrier plate for the support of the traction/thrust device and the coupling uptake at the underframe in each instance is a shock absorber which in case of excessive shocks becomes deformed elastically and/or plastically and permits a deformation path preset for the force acting at the time.

摘要： A yoke for a railway car coupler assembly includes a yoke body having a generally rectangular front portion. A central opening provided in the front portion extends longitudinally therethrough. A pair of opposed first and second straps extend rearwardly from the front portion and are connected by a bridge portion. The side walls of the front portion are tapered inwardly toward the bridge portion to accommodate a striker having thickened side walls. Also, recessed portions are provided in the yoke central opening to accommodate the shank of a strengthened coupler. A bearing pad provided on the yoke bridge portion has relieved areas to prolong the service life of the yoke.
