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.
Claims6
A self steering construction for axles and wheels of railway trucks, comprising an adapter journal box, a bearing complex adapted to receive the truck axle and including an outer race for bearings, opposed spring elements engaging the sides of the said race and the side inner faces of the journal box, the journal box having an upper wall with a smooth metallic under face, a cylinder section resting on the outer face of the bearing complex, said cylinder section having a smooth metallic upper face receiving the under face of the journal box, and metallic faces of the journal box and the cylinder section being relatively eccentric, whereby upon angular movements of the axle and bearing complex rotational force will be imparted to the cylinder section, effecting rotation and rise of the cylinder section and thereby raising the journal box along with the truck frame resting upon it.
