Abstract
An implement drive arrangement for a wheel axle assembly pivotally connected to a housing. A drive element is supported on the axle for rotation with the wheel generally about the wheel axis. The housing rotatably supports a driven element for rotation about an axis generally fixed in relation to the housing. A free-floating connecting element is rotatably supported between the drive element and the driven element to facilitate relatively unimpeded pivoting of the axle and wheel relative to the housing. The connecting element has two degrees of freedom offset at 90° to one another and aligned radially relative to the axis of rotation to accommodate axle pivoting while assuring smooth transfer of power from the wheel to the driven element as the angular relationship changes between the axle and housing with movement of the wheel over irregular ground surfaces.
