An identical steer control mechanism of a radial bar-link trapezoidal swing arm, a method and a multi-wheel vehicle thereof are disclosed. The radial bar-link trapezoidal swing arm is in a right triangle shape, and in combination with a two-dimensional composite control transmission arm of a cross-shaped groove formed by a transverse groove and a vertical groove, an elliptical gauge is shaped; the longitudinal cosine displacement is controlled by the sliders in the transverse groove, and the transverse sine displacement can be controlled by connecting the sliders in the vertical groove after the right-angle end bearing is hinged to connecting rods, the end bearing on the two-dimensional composite control transmission arm, namely the key control point bearing, draws a deflection elliptical trajectory, and the hinged slider to the key control point bearing is connected with a vector control swing arm sliding slot to generate a steering angle βi.

It is provided a multiple track and multiple axle motor vehicle, having at least two front wheels, at least two rear wheels, and a steering apparatus which is configured for steering the front and rear wheels of the motor vehicle. The at least two front wheels can be pivoted in each case about a front wheel steering rotational axis by means of the steering apparatus, the front wheel steering rotational axes being oriented in each case in such a way that a negative caster is produced in relation to the respective front wheel, and the at least two rear wheels can be pivoted in each case about a rear wheel steering rotational axis by means of the steering apparatus, the rear wheel steering rotational axes being oriented in each case in such a way that a positive caster is produced in relation to the respective rear wheel.

This disclosure is an auxiliary system to provide additional power for vehicles which can be applied to land wheel type vehicles without depending on rails, to convert most of the front-wheels drive and rear-wheel drive vehicles to multi-power all-wheel drive vehicles with low cost. Modification can be completed by merely three steps: 1. Arranging this disclosure on a non-driving wheel shaft. 2. Connecting the control box (1) with the brakes (7), a gas pedal (8) and the dashboard. 3. Placing the rechargeable battery packs (6) to the spare position of the vehicle. Adding one to a plurality of motors (5) which are additionally arranged on a non-drive shaft and controlled by the controlled box (1) according to the single-chip microcomputer (2) in the control box to decide whether to apply the auxiliary power according to preset commands, the status and speed of the vehicle, and signals transmitted by the brakes (7) and a gas pedal (8) of the vehicle. The advantages of this disclosure are of being capable to widely install on existing gas vehicles to provide auxiliary power without changing the current vehicles' systems and the modification cost is low.

It is provided a multiple track and multiple axle motor vehicle, having at least two front wheels, at least two rear wheels, and a steering apparatus which is configured for steering the front and rear wheels of the motor vehicle. The at least two front wheels can be pivoted in each case about a front wheel steering rotational axis by means of the steering apparatus, the front wheel steering rotational axes being oriented in each case in such a way that a negative caster is produced in relation to the respective front wheel, and the at least two rear wheels can be pivoted in each case about a rear wheel steering rotational axis by means of the steering apparatus, the rear wheel steering rotational axes being oriented in each case in such a way that a positive caster is produced in relation to the respective rear wheel.

The present invention provides a vehicle including wheels, and a steering module configured to steer the wheels in one of two mutually opposite right and left directions, or in one and the other of the two mutually opposite right and left directions, respectively. In the vehicle, a caster angle is set within the range of 3 degrees relative to a kingpin angle. Though each wheel usually forms a camber angle when steered, by setting in the wheel the caster angle beforehand within the above range, the wheel does not or is less likely to form the camber angle because the camber angle and the caster angle cancel each other. Therefore, it is possible to prevent the steering angles of the wheels from being restricted, and to prevent the deterioration of steering operability.

A universal steering system designed for all-wheel drive, remote control, zero turn, and positive traction. The universal steering system is configured to control the wheel deflection of each wheel of a vehicle. The universal steering system is usable for vehicles including automobiles, motorized dollies, floor jacks, toolboxes, tables, carts, skateboards, and other wheeled vehicles.

The present invention relates to an assembly which includes: a chassis for a mobile land vehicle, in particular an agricultural or public works vehicle; at least two half-crossmembers (21) mounted telescopically on the chassis; wheel mountings (27) pivotably mounted on each one of said half-crossmembers; steered wheels rotatably mounted on said mountings; and a device for controlling the direction of the wheels. The assembly is characterized in that it includes means (39, 41, 47) designed, for a certain position of two half-crossmembers, to increase, upon the pivoting of the wheels, the opening of the said wheels relative to the opening of the wheels resulting from the same pivoting and another position of the two half-crossmembers.

A steering intermediate arm for linking dual steer axles on a vehicle is mountable for pivoting movement on a vehicle frame rail about a non-horizontal axis. The intermediate arm provides for a connection between a first linking rod extending rearwardly from a pitman arm and a second linking rod extending rearwardly to a steering arm of a rearward steerable axle of the dual steerable axles.
