<p>A structure interlinking the axle (2) with the hubs (3) of steering drive wheels, particularly for use on such agricultural machines as tractors and the like, comprising two cup-shaped bodies (4,5) respectively unitary with the axle and the wheel hub. The cup-shaped bodies are face coupled together in a relationship of relative rotation about the steering axis of the wheel by means of respective helical threadways (19,20) having a coincident axis (X-X) with the steering axis. <IMAGE></p> |
