摘要： The present invention relates to a train coupler adapted for energy absorption by the use of a deformation unit. According to the invention an axial expansion module is provided and mounted together with the deformation unit and an anchor in the housing of the train coupler. By expanding the axial expansion module after being mounted into the housing, the deformation unit and the anchor will be biased between the front and rear lugs of the housing and held in place by a predetermined force in the axial direction only.

摘要： The invention relates to a coupling arrangement for a rail vehicle that includes a coupling rod which extends along a longitudinal axis, a bearing bracket to which the coupling rod is connected at a second axial end, a bearing between the bearing bracket and the coupling rod, and a support structure which elastically supports the coupling rod in relation to the movement in the vertical direction. The support structure is positioned in the vertical direction at least predominantly level with the bearing bracket and/or with the coupling rod in a manner substantially coaxial with respect to the longitudinal axis.

摘要： A rail road car has draft sills, and draft gear mounted in the draft sills, by which loads are passed along the train line of cars. The draft gear is mounted to the drafts sill webs between front and rear draft stops. The front and rear draft stops have portions that protrude beyond the plane of the inner face of the draft sill webs. The rear draft stops have a boss that extends past the plane of the inside face of the draft sill web, such that the peripheral weld about the boss may tend to be placed in stress in the plane of the web.

摘要： The present invention provides a lightweight draft sill end casting for use with railroad cars. Weight reductions are achieved and adequate strength is maintained by using a set of front ribs and back ribs, with angled top and bottom ribs. The back rib set has a single central rib along the central plane of the draft sill. A single horizontal center plate rib is also used in the area of the center plate. The side ribs at the center plate have larger lightener holes. Holes are also provided in the bottom wall of the casting. Larger lightener holes are provided in the area of the draft sill pocket. These holes are moved upwardly to lower the center of gravity of the draft sill. The draft stops may be spaced from the top wall of the draft sill and from the bottoms of the side walls.

摘要： To maintain horizontal alignment of a shank and attached coupler head of a rotary railroad coupler system, a middle portion of the shank is supported by a carrier assembly connected to a striker casting of the coupler system. During rotation of the shank and coupler head in a dumping procedure, for example, the shank interfaces with a saddle casting portion of the carrier assembly to cause wear thereof. To facilitate replacement of the saddle casting portion once wear becomes excessive, the saddle casting portion is provided with spaced inverted T-shaped lugs which allow the saddle casting portion to be removed from a carrier portion of the carrier assembly by means of spaced grooves provided in the carrier portion. Separation of the saddle casting portion from the carrier portion, however, is prevented when the saddle portion and carrier portion are misaligned.
