Abstract: Saddle type self-steer axle systems equipped wagons may include two or more axles and may be backed up due to reversing caster. Such systems may provide increased stability by providing four points of contact. Further, such systems may provide improved weight distribution in that weight may be distributed over four points as opposed to three points. In addition, such systems may provide increased safety by raising the rollover threshold to that of the tow vehicle. Such systems may allow a tow vehicle to carry its full allowable gross weight while towing its full allowable tow weight. In addition, a centrally pivoting saddle style hinge system may reduce the actuator force that may be needed to change the caster from forward to reverse and vice versa.

Abstract: A self propelled irrigation system has a drive tower on which a drive wheel is mounted to a rotating member of a drive mechanism with an axis of the wheel obliquely angled relative to a drive axis of the rotating member such that the wheel is tilted out of a plane normal to the drive axis. A hub has its oppositely facing sides arranged to support the wheel in such an orientation, and may therefore be mounted between the drive mechanism and wheel of a conventional irrigation system in which the wheel and drive axes were previously coincident. The tilt of the wheel causes an intentional wobble under rotation of the hub so that the wheel's point of engagement with the ground wanders back and forth during repeated passage of the drive tower over a particular path, thereby reducing a rut forming or deepening tendency of the irrigation system.

Abstract: Disclosed herein is a wheel angle adjustment apparatus for automobile suspension systems. The wheel angle adjustment apparatus of the present invention has a structure such that upper, lower, left and right gaps between a spindle bracket and a wheel bracket are changed by tightening or loosening a plurality of locking bolts that couples the spindle bracket and the wheel bracket together. Therefore, toe and camber angles of each wheel are easily adjusted by tightening or loosening the locking bolts. In particular, when the present invention is used in a suspension system such as a torsion beam suspension system which has a structure such that a wheel alignment using a connection part provided between the automobile body and wheels is impossible, the wheels are easily aligned merely by adjusting the gap between the spindle bracket and the wheel bracket.
