Abstract: A wagon for agricultural use having an all-wheel steering mechanism. The wheels are hingedly attached to their respective axles. Steering alignment of the front wheels is provided by the wagon tongue, which is pivotally connected to the wagon frame and at least one of the front wheels. The front wheels are connected to each other by a steering linkage, consisting of two equal length members pinned to each other at a connection point. A front shaft crank is pivotally attached at the same connection point and rigidly attached to a rotatable shaft mounted with bearings to the underside of the wagon frame. Changes to the steering alignment of the front wheels causes lateral movement of the connection point, leading to rotation of the shaft and a corresponding direct change in alignment of the rear wheels, which are equipped with a similar system of linkages and cranks. This causes the front and rear wheels to follow the same path.

Abstract: A nontrack-bound vehicle with arbitrarily steerable front wheels includes an additional rear-wheel steering system that operates automatically or may be switched to automatic operation and controls or regulates the steering angle of the rear wheels as a function of the steering angle of the front wheels and of further parameters. The additional rear-wheel steering system switches in a parameter-dependent manner between a drive-away mode and a normal mode to improve maneuverability and to reduce the swinging out of the rear during the drive-away mode. In the drive-away mode, the steering angle of the rear wheels is controlled or regulated so that the rear wheels are not adjusted beyond a steering angle assumed when the vehicle last halted.

Abstract: A two-wheeled scooter with a frame and a standing board attached thereto. Two steering tubes, each with a pivotable fork for the front or rear wheel, are provided on the frame. The steering tubes are inclined toward one another and relative to vertical at an acute angle. The turning angle of the front wheel causes a turning angle of the rear wheel via a connection arrangement. The steering connection between the front wheel and the rear wheel is carried out by driving disks, which are attached in rotation-proof fashion to the forks and connected to each other, for example, via a flexible steel cable, so that the front and rear wheel forks turn in opposite directions with the same turning angle. Because of the dependence of the steering movements of the front and rear wheels and their control by a standard bicycle steering rod with a handle bar, travel is controlled precisely and thus operational safety is optimized.

Abstract: A four wheel steering system for a vehicle which significantly reduces or eliminates scrubbing of the outside tires. A preferred embodiment is specially adapted for use on riding lawn mowers, and includes a longitudinally moveable cam plate having a pair of cam slots formed therein, each slot engaging an individual steering arm for separately steering each rear wheel. The cam plate is coupled to a sector gear which reciprocates in response to left and right hand movement of a steering wheel, with the sector gear interconnecting the front and rear wheel steering mechanisms. The slots in the cam plate are specially configured to vary the turning angles of the rear wheels so that the wheels turn through varying angles, thereby reducing scrubbing to an acceptable level. In a preferred embodiment, all four wheels may be calibrated to turn about a single point, thereby completely eliminating scrubbing.

Abstract: In a steering mechanism wherein the turning angle of a steering wheel is transmitted to a wheel via a link mechanism employing a tire rod (3) and a knuckle arm (4), the link mechanism and the wheel (1) are coupled by a multiplying gear (2). Individual drive mechanisms are mounted independently on each wheel, and each wheel is driven independently to enable front-wheel independent drive, rear-wheel independent drive and four-wheel independent drive. Drive of an inner rear wheel is changed over at a steering angle in the vicinity of 90.degree. to effect control of steering. A steering angle multiplied twofold or more can be obtained in simple fashion via the multiplying gear (2) even for a steering angle of about 45.degree. using the conventional link mechanism. In the drive of each wheel, drive of the inner rear wheel is halted in the vicinity of the 90.degree. steering angle, so that locking of the inner front wheel can be avoided.

Abstract: Steering mechanism for trailer wheels is provided with a slide having a tongue selectively engaged with and retracted from the fifth wheel of a tractor. When the tongue is engaged with the fifth wheel, any pivoting of the fifth wheel about the kingpin connection between the tractor and trailer, as when the tractor is steered from a straight ahead position relative to the trailer, causes the tongue to swing a link pivoted on the slide mechanism under the trailer. This swinging of the link drives a flexible cable to control a valve of a power steering system for the trailer rear wheels. The components are mounted under the floor of the trailer and a cable driven winch with a crank or power drive at the side of the trailer advances and retracts the slide to move the tongue into and out of engagement with the tractor fifth wheel. Magnets are mounted in the tongue and a torsion spring is provided in the winch mechanism to maintain tight contact between the tongue and fifth wheel.

Abstract: A steering and suspension system which steers and tracks all wheels of a vehicle and banks the vehicle body during turns. Front and rear power assisted rack and pinion steering assemblies are mechanically linked so that the rear wheels are turned in the opposite direction of the front wheels relative to the longitudinal axis of the vehicle. The power assistance turns the radially inward wheels to a greater degree than the radially outward wheels. A pendulous mass is suspended from the vehicle body to react to centrifugal force and is operationally linked to a camber and attitude adjustment spool valve to regulate fluid flow to front and rear camber pistons and to hydraulic shock absorbers. The spool valve responds to swing of the pendulous mass to channel fluid to the camber pistons which cause the vehicle wheels to lean into a turn. Moreover, the spool valve channels fluid to the shock absorbers that are radially outward of a curve to bank into a turn.
