| 147 | Lightweight, adjustable-height, axle | US09511596 | 2000-02-23 | US06416136B1 | 2002-07-09 | Fred P. Smith |
| A lightweight axle assembly may include a bracket at each end thereof for receiving a mount at one of a plurality of positions thereon. The mount may include a standoff for spacing an actual wheel assembly a suitable distance from the bracket. The axle may be formed to include a beam for suitable cross section including I-beams, channels, or boxes, as well as cylindrical tubes. Wheels may be mounted to spindles rigidly attached, to driving axles contained within the axle assembly, or to kingpins secured to the mounts. The axle may be adjusted to accommodate a broad range of suitable, relative, distances between the mounting surface (top or bottom of the axle end) and the center line of a wheel assembly associated with the axle. Forged mounts may be manufactured to accomplish structural objectives. Meanwhile, areas of less stress may be fabricated from lighter materials of various unconventional configurations. | ||||||
| 148 | Suspension and steering system for a vehicle | US09365253 | 1999-07-30 | US06406043B1 | 2002-06-18 | Charles Balmer |
| A steering and suspension arrangement for agricultural vehicle includes a horizontal axle transverse to the direction of movement with the ground wheel mounted at each end of the axle. The length of the axle can be adjusted by extending and retracting end portions of the axle relative to a centre section of the axle. Each end of the axle carries a wheel hub on a suspension arrangement defined by an upper plate, a lower plate, a first channel member attached to the lower plate and a second channel member attached to the upper plate with the channel members facing each other and connected by two parallel pivoting links. Between the plates is mounted a gas bag spring. The frame is divided into a front portion and a rear portion which are held against steering movement but can pivot, each relative to the other about a horizontal axis along the direction of travel to accommodate twisting beyond the limited suspension movement. The steering is effected by steering movements of the front wheels controlled by two separate cylinders which are arranged in a hydraulic circuit which automatically compensates for any fluid leakage to maintain the wheels aligned. | ||||||

| The invention is directed to a vehicle front-drive axle assembly having a front differential including a housing supporting left hand and right hand one-piece assemblies. Each of the left hand and right hand assemblies extend outwardly from the housing, and include an axle tube having a first end coupled to the housing and a second end having an integral yoke member. The one-piece assemblies further have integral bracket assemblies having outwardly extending mounting portions for mounting of vehicle suspension components and for securing the axle assembly to the vehicle.

| 151 | Vehicle with hydraulically adjustable tie rod | US220237 | 1994-03-30 | US5489113A | 1996-02-06 | David H. Torborg |
| A tie rod assembly for a steering wheel structure for an agricultural vehicle such as a row crop applicator uses hydraulic cylinders to set the track width of the vehicle. The track width may be modulated between a minimum and a maximum track setting and modified until a desired track width is achieved while the vehicle is in motion and negotiating a turn without affecting toe-in settings. Toe-in settings are maintained by a closed loop series hydraulic system which further has the capability to reinitialize any toe-in setting to a preset condition in the event any hydraulic cylinder experiences cylinder drift. | ||||||

| A steering axle includes a beam pivotally mounted on a load-bearing structure of a vehicle. A steering actuator is mounted on the beam and includes a casing which provides a journal formation for pivotally mounting the beam on the load-bearing structure. | ||||||
| 153 | Hydraulically adjustable tie-rod for an agricultural vehicle with an adjustable axle | US996290 | 1992-12-23 | US5282644A | 1994-02-01 | Roger L. Larson |
| A variable tie-rod assembly for a steering wheel structure of a row crop applicator. The tie-rod assembly can be adjusted and secured in any position between a minimum and maximum track setting. Thus, a selectively variable track width is provided. Toe-in settings are maintained by implementing a dual-cam arrangement with a locking pin to maintain the steering structure in a forward direction during track width adjustment procedures. The track width setting can be adjusted without the operator ever having to leave the cab of the row crop applicator, wherein the track width can be visually ascertained by observing indicia on the telescoping wheel structure. | ||||||
| 154 | Steering mechanism | US789640 | 1977-04-21 | US4109747A | 1978-08-29 | John T. Hornagold; Gary H. Beckley; Ram N. Rathi |
| A steering mechanism particularly suited for vehicles of the type having a variable width track. The steering mechanism is flexible enabling it to automatically extend and retract laterally along with the track of the wheels of the vehicle. The mechanism acts on steering arms of the steerable wheels of a vehicle to simulate a conventional tie rod type of steering geometry. During turning, the inner wheel turns more than the outer wheel to minimize tire slippage or scrub. A flexible steering linkage assembly is connected between the steering arm ends of the pair of steerable wheels to maintain controlled spatial relationship between them which results in a simulation of tie rod steering geometry. | ||||||

| The vehicle described comprises: two side chassis structures respectively provided with driving and steering wheels and spaced-apart from each other by transverse members; driving and transmission means; means for varying the distance between to the two structures, actuated by driving means including at least one jack; operating means acting from a driving station for steering wheels including at least one composite coupling rod constituted by two transverse rods; and means for synchronizing the variations in distance apart of the structures and of the length of the coupling rod. One of the rods is provided in the form of a toothed rack in engagement with a toothed pinion and the synchronizing means comprise a further transverse toothed rack, similar to the said coupling rack and in engagement with another pinion similar to the said coupling pinion, and a longitudinal shaft of variable length provided at its two extremities with universal joints coupling the pinions together for rotation. The relative arrangements of the pinions on their respective toothed racks is adapted to the realtive positions of the chassis portions with which the racks and pinions are associated.
