Abstract:
An assembly for coupling adjoining ends of a pair of reaction arms in a steering linkage of a railway truck, said assembly comprising:a joint between the reaction arms comprising a rigid frame; an elastomeric bushing secured at one portion thereof to the frame and to one of the arms at another portion thereof; and a stack of elastomeric pads secured at one portion thereof to the frame and at another portion thereof to the other arm, with the frame being free of any direct connection or engagement with either arm, wherein pivotal movement between the adjoining ends of the arms is accommodated and resiliently resisted by the elastomeric bushing, and further wherein relative longitudinal movement between the adjoining ends of the arms is accommodated and resiliently resisted by the stack of elastomeric pads, with the frame being free of any direct connection or engagement with either arm, whereby relative longitudinal and pivotal movement between the adjoining ends of the arms is accommodated and resiliently resisted by deformation of the elastomeric bushing and stacks of pads, thus avoiding direct frictional engagement between the arms or between the arms and the frame, or both, subjecting these components to wear.
