摘要： A side bearing assembly for a railway vehicle includes a cage, a cap coupled to and moveable relative to the cage, and an insulator disposed between the cage and the cap. The railway vehicle includes a bolster extending laterally and a car body disposed on the bolster. The cage is attached to the bolster and the cap supports a portion of the car body such that the side bearing assembly is disposed between the bolster and the car body to dampen lateral pivoting of the car body relative to the bolster. The insulator is formed of microcellular polyurethane for resiliently deforming and storing energy during compressive movement between the car body and the bolster through a range of temperatures between −40° C. and 80 ° C. Microcellular polyurethane maintains flexibility at this temperature range such that the side bearing assembly maintains its ability to dampen lateral pivoting through this temperature range.

摘要： An elastomeric spring including an elongated elastomeric body defining a longitudinal axis for the spring and having first and second longitudinal ends. An outer surface of the elastomeric body extends between the first and second ends and has four generally planar sides, with each planar side of the outer surface being disposed to one side of and generally parallel to the longitudinal axis of the spring so as to reduce radial bulging of the spring in all directions when an axial load is applied to the spring. The outer surface of the elastomeric body further includes four angled corner sections extending between the first and second ends of the elastomeric body and disposed a substantially common distance from the longitudinal axis of the spring. One corner section is disposed between any two adjoining sides on the outer surface of the elastomeric body.

摘要： A side bearing provides contact between a truck bolster and a railway car body. The side bearing includes a cage member mounted on top of the bolster. An insert member is fit within an opening in the cage member. A top member is mounted above the insert member for vertical movement relative thereto. The insert and top members have pocket sections that together form at least one pocket there between. Resilient devices, such as elastomeric unitary pieces, are positioned in each of the pockets for supporting the top member relative to the insert member. The side bearing components we configured to provide up to 0.625 inches of vertical displacement of the top member relative to the insert member.

摘要： A constant contact side bearing assembly configured for insertion into a walled receptacle provided on an upper surface of a railcar bolster. The constant contact side bearing assembly includes a walled housing defining a cavity extending therethrough and open at opposite ends and a spring having a first end, abuttingly engaging a portion of the upper surface of said railcar bolster, and a second end, axially spaced from the first end. A cap is arranged at the second end of the spring. The cap is mounted for reciprocatory guided movements by and relative to the housing, with a generally flat railcar body engaging portion on the cap being positioned relative to the housing and the walled enclosure by the spring. The side bearing assembly further includes an apparatus for locating and securing the side bearing assembly within the walled receptacle on the railcar bolster.

摘要： An elastomeric spring assembly for a railcar apparatus is disclosed. The elastomeric spring assembly includes an elongated body of elastomeric material having a series of axially spaced members coaxially arranged and wholly embedded within the body of elastomeric material. The majority of the embedded members are configured to resist radial outward movement of said elastomeric material while causing the elastomeric material to react in an axial direction between confronting surfaces defined by the members upon axial deflection of the elastomeric spring whereby enhancing performance characteristics of the spring assembly. A method of making an elastomeric spring assembly is also disclosed.
