Abstract: State of the art track width adjustment mechanism fail to support track width adjustment while vehicle is in motion. They also require manual intervention, which causes inconvenience. The disclosure herein generally relates to wheel track adjustment, and, more particularly, to a changeable wheel track mechanism for track width adjustment (referred to as TWA mechanism). The TWA mechanism includes a steer and drive unit, a plurality of links, and a sliding unit. The TWA mechanism allows movement of a wheel in inward and outward directions, causing the track width adjustment. The track width is achieved by changing the wheel position to be at a wider position, or a narrower position, or any intermediate position. The TWA mechanism may be associated with any vehicle for which the track width adjustment is to be achieved.

Abstract: Provided herein is a driving apparatus for transporting a loaded object, which allows a drive-wheel to always be in contact with the ground even when the ground is uneven. The driving apparatus includes a loading plate (140, 240) on which a loaded object is loaded, a first support (110, 210) connected to a lower portion of one side of the loading plate (140, 240), a second support (120, 220) connected to a lower portion of the other side of the loading plate (140, 240), a hinge (130, 230) configured to connect the first support (110, 210) to the second support (120, 220) in a hinge structure, at least a pair of drive-wheels (160, 260) coupled to both sides of a lower portion of the second support (120, 220), and a driver configured to rotate and drive the drive-wheels (160, 260).

Abstract: There is described a wheel axle for an agricultural vehicle such as a combine harvester. The wheel axle has at least one wheel suspension (32a) arranged to maintain a wheel axle parallel to the supporting surface, through use of a linkage arrangement (36, 38, 40) which is pivotally coupled to the axle frame (30). The configuration of the wheel suspension allows for the wheel axis to passively follow the surface profile, as any loads transmitted through the wheel carrier act to level out the wheel suspension to align with the underlying surface. As the wheel axle is adjusted to lie parallel with the underlying surface, accordingly the ground-contacting surface area of the associated wheels is maximised.

Abstract: An axle assembly may have a first axle member, including a recess with a female threaded portion, and a second axle member with an insertion portion and a protrusion portion. The insertion portion may be received in the recess and it may have a male threaded portion engaged with the female threaded portion of the first axle member. The protrusion portion protrudes out of the recess. An overall length of the axle assembly is adjustable by moving the threads of the male threaded portion of the second axle member along the threads of the female threaded portion of the first axle member, or vice versa. An axle and hub arrangement with the axle assembly is also disclosed.

Abstract: A vehicle wheel positioning and steering apparatus particularly useful for aerial work platforms comprises a support chassis and chassis support legs pivotally connected to the chassis. Steerable wheel assemblies are operably connected at ends of the support legs and powered actuators are operably connected to the chassis and legs for pivotally moving the legs and wheel assemblies relative to the chassis between transport and working positions. Variable length linear wheel steering actuators comprise one link of four bar parallelogram steering linkages between the chassis and wheel assemblies and the support legs each comprise second bars of the four bar parallelogram steering linkages.

Abstract: A track-width adjustment system, apparatus and method limit track-width adjustments in a self-propelled product applicator, according to a first speed-based protocol for track-width adjustments initiated by an operator of the applicator, and according to a second speed-based protocol for track-width adjustments initiated by an automatic track-width control arrangement of the applicator. An automatic track-width control arrangement continually monitors and adjusts track-width, as required to maintain a desired track-width at substantially any ground speed while the applicator is in motion. Operator initiated adjustments to track-width are allowed only within a prescribed range of ground speeds.
