摘要： A rail car truck bolster wear plate surface connects to a wear plate using two fasteners of different length. The first fastener passes through an upper opening and an upper channel into a first recess where it can be tightened against a first engaging surface. The second fastener is longer than the first fastener and passes through a lower opening and lower channel into a second recess adjacent to the first recess. The surfaces of the first and second recesses form a series of ribs in the upper end surface between the wear plate surface and the longitudinal centerline of the bolster.

摘要： A temperature-robust polymer shroud for a roller bearing seal includes a shroud body and an inner diameter leg defining respective portions of a single continuous part. The shroud body encircles a rotation axis of the polymer shroud and extends predominantly in directions orthogonal to the rotation axis from an inner diameter to an outer diameter. The inner diameter leg connects to the shroud body at the inner diameter, encircles the rotation axis, and is oriented at an oblique angle to the rotation axis to extend both (a) radially inward from the inner diameter and (b) axially away from the inner diameter along a first direction parallel to the rotation axis. A roller bearing seal includes a seal case, an elastomer lip, and the temperature-robust polymer shroud.

摘要： A rail vehicle with two sideframes and a bolster as the freight car truck has limits on stability. A railway freight car truck having a friction shoe with a constant force device acting directly on the shoe flat surface is provided, such that the friction shoe is forced to remain in contact with the side frame mating vertical surface. The control spring acting on the friction shoe which applies a varying force to the side frame mating surface. The damping of the friction shoe is retained when there is less variable force of friction, which decreases vertical acceleration of the rail vehicle, providing high speed stability for most track conditions.

摘要： A bearing assembly comprising a bearing cup having two ends, with a pair of outer raceways formed one adjacent each end of the bearing cup. A pair of bearing cones form a pair of inner raceways. Two rows of tapered roller bearings with each row received between one inner raceway and one outer raceway. A pair of wear rings are provided, each having a first axially inwardly directed end in engagement with an outwardly directed end of a bearing cone. A pair of seals each having a first end fitted into one into one of the bearing cup cylindrical counterbores. Each seal has a second end including a resilient element to form a seal with one of the wear rings. A second end of each wear ring is received in a cylindrical counterbore in each annular backing ring. A circular shroud is located radially outer and adjacent to one seal.

摘要： A railway truck to railway car body interface is provided. The railway truck is comprised of a bolster supported between two sideframes. The truck bolster includes a center bowl, and the car body includes a body bolster opening. A center plate is placed between the truck bolster center bowl and the car body bolster opening. A wear liner, usually comprised of an elastomeric material, is provided between the sides of the center bowl and the center plate.

摘要： The traditional three piece railway freight truck prevents the wheel sets from achieving radial alignment to curves by the rigid side frames restraining the wheelsets. The side frames also constrain the wheelset from radial aligning to curves by the limited gap between the wheelset bearing and the side frame pedestal jaws.The present invention opens the side frame pedestal jaws to allow the wheel sets to yaw and align radially to curves. The side frame is supported on wheel sets by elastomeric pads and bearing adapters. The present invention utilizes the elastomeric pad stiffness to compress in pitch motion that allow the wheel set to move in an arc forward or backward in the open jaws of the side frame. The elastomeric pad stiffness also allows the wheelset to twist the pads allowing the wheelset to radially align to the curve. The pads elastic stiffness is sufficient to return when the wheelset is align to straight track.

摘要： A friction shoe for a railway car truck is provided. The railway truck comprises two parallel side frames, a suspension spring assembly supported by the side frames, and a bolster transversely mounted between the side frames and supported by the suspension spring assembly. Each side frame has at least one vertical support face,and the bolster has at least one sloped support face. The friction shoe comprises a bottom base engaging and supported by a pair of support springs, and a sloped wall engaging the sloped support face of the bolster. The bottom base includes a cylindrical spring lug that has a center opening that extends through the spring lug. The bottom surface of the spring lug is flat and smooth and is designed to engage with and provides the ability to use an additional concentrically nested support spring. The additional spring increases the force between the vertical support face of the wedge and the vertical wear plate of the side frame.

The railway truck comprises two parallel sideframes, a suspension spring assembly supported by the sideframes, and a bolster transversely mounted between the sideframes and supported by the suspension spring assembly. Each sideframe has at least one vertical support face, and the bolster has at least one sloped support face. The friction shoe comprises a bottom base engaging and supported by a suspension control spring, a sloped face engaging the sloped wall of the bolster. The friction shoe further includes a vertical face including a pocket, with a friction liner in the pocket. The friction liner engaging the vertical column of the sideframe. The friction shoe friction liner comprised of a material providing a damping force of between 700 and 16,250 pounds and a normal force of between 2000 and 12,000 pounds.
