Abstract:
1. A high misalignment wheel drive, comprising: a spline drive combinable with an axle shaft for rotation around an axis of the axle shaft, the spline drive including an external crown spline; a drive plate for rotation about a drive plate axis, the drive plate including an internal spline for engaging the external crown spline in a pivotable splined connection to allow the spline drive to rotationally drive the drive plate while the drive plate axis is non-aligned with respect to the axle axis by up to an angle α, the drive plate including a mounting arrangement for mounting to a driven wheel; a first thrust face positioned with respect to the spline drive to rotate with the spline drive; a second thrust face positioned with respect to the first thrust face to rotate with the spline drive; a third thrust face positioned with respect to the drive plate to rotate with the drive plate for engaging the first thrust face; and a fourth thrust face positioned with respect to the drive plate to rotate with the drive plate for engaging the second thrust face; wherein the first thrust face and second thrust face define an angle of movement between which at least one chosen from the third thrust face and the fourth thrust face can pivot with respect to the spline drive between a position where the third thrust face engages the first thrust face, and a position where the fourth thrust face engages the first thrust face.
