摘要： An improved three-piece truck system for railroad cars provides long travel side bearings for improved stability, a “wide” friction shoe design or equivalent to improve sideframe and bolster squareness, a resilient pedestal pad for improved curving performance and enhanced wear resistance, and a suspension system tuned and optimized for rail cars to have a minimum reserve capacity of less than 1.5 to improve motion control and ride quality, increase resistance to suspension bottoming, and increase hunting threshold speed. Such a motion control truck system is able to meet recent, more stringent American Association of Railroads standards, such as M-976, for railcars having a 286,000 lb. gross rail load rating.

摘要： An improved sideframe has a bolster opening configured to accept a variety of spring group and friction shoe assembly designs. The bolster opening is defined by a bottom section, a top compression member, and two opposing column members and has two column wear plates each secured to the opposing column members. The bottom section of the bolster opening defines a spring seat. The dimensions of the bolster opening of the sideframe allow for a variety of freight car truck suspension systems including the spring group, bolster and friction shoe used therewith.

摘要： A tuned spring group with load springs, control springs, and a frictional damping arrangement for a railcar truck assembly provides better ride quality, increased resistance to suspension bottoming, and increased hunting threshold speed of a railroad car. Specifically, this tuned damping and suspension arrangement provides a spring group reserve capacity of less than 1.50. Spring assemblies for different car types are tuned such that a reserve ratio less than 1.50 may be achieved. By reducing the spring assembly reserve capacity for a railcar and truck of a standard weight and configuration to less than 1.50, an unexpected result of a decrease in maximum vertical acceleration as the railcar truck assembly approaches a speed of 55 miles per hour is achieved. The decrease in vertical acceleration allows for improved ride quality, increased resistance to suspension bottoming and increased hunting threshold speed of the railcar.

摘要： A cast metal sideframe for use in a railway car truck has a spring seat for supporting the springs of a spring set. The sideframe is molded using a core that includes a portion for defining the exterior surface of the spring seat. The core can be a single piece or multi-piece core. The spring seat includes a plurality of aerodynamically-shaped spring retainers formed on the top face spring seat. The aerodynamic shape of the spring retainers reduces the tendency for sand to swirl and create voids during formation of the sand core that is used to mold the sideframe. The aerodynamic shape may include forming at least some of the side walls of the spring retainers at an obtuse angle with the top face of the spring seat. The spring retainers may have concave top faces so as to reduce the volume of material comprising the spring retainers. Reducing material volume is beneficial for reducing shrinkage during cooling of the sideframe, thereby reducing the tendency for separation, tears and cracks to form on the top surface of the spring retainer.
摘要翻译： 用于铁路车辆的铸造金属侧架具有用于支撑弹簧组的弹簧的弹簧座。 侧框使用包括用于限定弹簧座的外表面的部分的芯来模制。 核心可以是单件或多件式核心。 弹簧座包括形成在顶面弹簧座上的多个空气动力学形状的弹簧保持器。 弹簧保持器的空气动力学形状减少了在形成用于模制侧架的砂芯的形成期间沙子旋转并产生空隙的趋势。 空气动力学形状可以包括以与弹簧座的顶面成钝角形成弹簧保持器的至少一些侧壁。 弹簧保持器可以具有凹的顶面，以便减小包括弹簧保持器的材料的体积。 降低材料体积有利于减少侧架冷却期间的收缩，从而减少在弹簧保持器的顶表面上形成的分离，撕裂和裂纹的趋势。

摘要： A railway car truck incorporating an interconnection between the side frame and bearing adapter is characterized by a low lateral spring constant relative to the longitudinal spring constant. The interconnection provides a proportional restoring force with minimal internal friction and hysteresis. In embodiments, the interconnection comprises compressed elastomeric members positioned between the thrust lug of the side frame and the bearing adapter in the longitudinal direction and a low friction interface between the roof of the pedestal jaw and the top of the bearing adapter.

摘要： A rail car truck has a pair of longitudinally spaced wheelsets and a pair of laterally spaced side frames which extend between and are supported by the wheelsets. A bolster extends between the side frames to support the rail car vehicle body. There is a brace which is connected to the side frames to control relative longitudinal movement therebetween. The brace includes a pair of struts which are diagonally connected to the side frame on opposite sides of the centerline thereof. The struts intersect generally centrally of the side frames and there is a clamp assembly for attaching the struts together. The clamp assembly includes a pair of clamp plates, each having a channel formed and adapted to receive a strut. Each clamp plate is welded to a strut and there are fasteners which attach the facing surfaces of the clamp plates directly to each other. The clamp plates are welded one to another. The clamp assembly inhibits relative movement between the struts in a generally horizontal plane.

摘要： A rail car truck side frame for use in a frame brace truck which has stabilizing cross braces extending between the side frames. The side frame has a top compression member and a bottom tension member which are joined by upwardly and outwardly slanted end walls. There is a bracket at the lower end of each end wall for use in mounting a cross brace. The bracket includes first, second and third walls, each integral with the side frame and each extending downwardly from the side frame. The first wall forms the wall for attachment of a cross brace with the second and third walls being perpendicular to the first wall and forming support for the first wall.

摘要： A rail car truck side frame has an upper compression member and a lower tension member, with these members being joined by integral end walls which slant upwardly and outwardly from the tension member toward the compression member. To protect the side frame from the elements of car progressors, there is a car progressor contact extending forwardly from the lower outward portion of each end wall of the side frame. The contact is formed and adapted to be contacted by and protect the side frame from the pusher of a car progressor. The car progressor contact may either be cast into the side frame or it may be a separate welded element. When the side frame is used in a frame brace truck, the car progressor contact may extend outwardly from the bracket which is attached to the side frame and supports the cross braces of the truck.
