Abstract

An electrical vehicle for road or internal transportation, in which all driving performances are carried out merely by controlling the relative rotation speeds and tilt-angle of each driving wheel, through a programmable control system, thus eliminating any mechanical means regularly utilized for this purpose, and enabling this vehicle to be driven by a person, or automatically along guiding elements, or by remote control, or to be programmed for travelling along a predetermined course without any external guiding measures.

Claims

1. An electrical vehicle with steering-by-driving for road or internal transportation, comprising:

at least one pair of driven wheels, each wheel of said pair of driven wheels being tiltable about a substantially vertical pivot which is excentrical to the vertical center of said wheel and steerable by means for imparting and varying relative rotational speeds between said pair of driven wheels;

a programmable control system for imparting and varying said relative rotational speeds to said pair of driven wheels;

a chassis to which said tiltable driven wheels are attached; and

,

means for transferring a driving torque from at least one pair of said tiltable driven wheels to said chassis of said electrical vehicle, said means for transferring including at least one pair of arms, each of said arms being attached to each wheel of said pair of driven wheels, and at least one connecting rod pivotedly interconnecting each said pair of arms at a trapezoidal formation.

2. The electrical vehicle according to claim 1, wherein each of said driven wheel pairs includes a built-in electrical motor and an electromagnetic brake unit, said electrical motor and said electromagnetic brake unit being protected from penetration of liquids, each of said driven wheel pairs being separately controllable through said programmable control system for rotational speeds, rotational direction and braking characteristics, a steering operation being effected by utilizing friction power between wheels and ground.

3. The electrical vehicle according to claim 1, further comprising means for an automatic controlled braking of said vehicle.

4. The electrical vehicle according to claim 1, wherein said electrical vehicle has four tiltable independently driven wheel units.

5. An electrical vehicle with steering-by-driving for road or internal transportation, comprising:

two pairs of driven wheels, each wheel of said two pairs of driven wheels being tiltable about a substantially vertical pivot which is excentrical to the vertical center of said wheel and steerable by means for imparting and varying relative rotational speeds to said two pairs of driven wheels;

a programmable control system for imparting and varying said relative rotational speeds to said two pairs of driven wheels;

a chassis to which said two pairs of tiltable driven wheels are attached; and

,

means for transferring a driving torque from said two pairs of tiltable driven wheels to said chassis of said electrical vehicle, said means for transferring including two pairs of arms, each of said arms being attached to each wheel of said two pairs of driven wheels, and two connecting rods, each pivotedly interconnecting one pair of two said pairs of arms at a trapezoidal formation.

6. The electrical vehicle according to claim 5, further comprising means for an automatic controlled braking of said vehicle.

7. The electrical vehicle according to claim 5, wherein said electrical vehicle has four tiltable independently driven wheel units.

8. The electrical vehicle according to claim 5, wherein each of said driven wheels includes a built-in electrical motor and an electromagnetic brake unit, said electrical motor and said electromagnetic brake unit being protected from penetration of liquids, each of said driven wheels being separately controllable through said programmable control system for rotational speeds, rotation direction and braking functions, a steering operation being affected by utilizing the friction power between said driven wheels and ground.
