ABSTRACT:
The under surface of an adapter journal box rests upon an assembly composed of semi-annular semi-spherical members consisting of a lower one resting on the outer race of the axle bearing complex, an upper one meeting the top inner face of the adapter journal box, and an intermediate one which is resilient and which may be of thick elastomer. The said assembly lies above and is endwise centered on two opposed and relatively strong resilient abutments, each between one side wall of the adapter journal box and the outer race of the axle bearing complex and which may be of the chevron type in which V-formed elastomer elements are spaced by coacting elements of metal.
