ADAPTER FOR MOUNTING EXTRA WHEELS ON VEHICLE CONTROLLED AXLE Russian patent published in 2013 - IPC B60B15/26 B60B11/06 

FIELD: transport.

SUBSTANCE: invention relates to agricultural machinery, particularly, to adapters for mounting extra wheels on harvester controlled axle in twinning its drive wheels or reequipping it to half-truck running gear. Proposed device is composed of single-step or multistep cylindrical hollow adapter with flanged ends. Adapter inner flange is jointed by ferrules and nuts to standard wheel disc secured by ferrules to hub studs. Note here that said adapter is squeezed in standard wheel rim by split ring with conical outer and inner surface, that is, trapezoidal cross-section, displaced uniformly over adapter outer cylindrical surface towards standard wheel rim arch unless ring outer conical surface thrusts against conjugate inner surface of the rim.

EFFECT: higher stiffness and reliability of extra wheel attachment.
