摘要：A side bearing for a railway truck and car body assembly includes a compliantbearing disposed within a cavity defined by a housing of the assembly. The compliantbearing includes a pair of elastomeric bearing elements each having a generally upwardlyfacing surface portion. The compliant bearing also includes a unitary rigid friction elementengageable with the bearing element surface portions and extending upwardlytherefrom. The friction element has a bearing surface disposed vertically above thehousing walls for frictional engagement with a wear plate. A rigid elongated spacer isdisposed within the cavity and has an upwardly facing surface as well as an upstandingabutment which is cooperable with at least some of the cavity walls to confine theelastomeric bearings within the cavity. A rigid bearing supported on the upwardly facingsurface of the spacer is movable thereon in opposed directions within predeterminedlimits. The rigid bearing is of an overall vertical height that, when supported on thespacer surface with the spacer disposed within the cavity the rigid bearing has anuppermost extent above the upper edges of the housing. The elastomeric elements arevertically deformable in compression and have an overall vertical height at the bearingsurface of the rigid friction element is disposed vertically above the uppermost extent of

the rigid bearing so as to maintain a vertical spacing between the rigid bearing and thewear plate throughout a range of vertically downwardly directed loadings applied to thecompliant bearing, and to permit the wear plate to engage the rigid bearing when thevertically downwardly directed loading equals a given load.
