As illustrated in pl. 1, fig. 1, the vehicle (1) is equipped with n. 4 wheels (2,3,4,5) powered by electric motors (6, 7, 8, 9) with rotors (25, 26, 27, 28) and relative elastic rings (10, 11, 12, 13).

The 4 wheels are steered with trapezes (14, 15) driven by the column (16) and by the steering wheels (17) hinged and rotating around the pins (18, 19) in order to reach an angle of 90 °; the internal combustion engine (29) is connected to the electric generator (30) for feeding the electric motors (6, 7, 8, 9) and from the electric accumulator (31) to the converter (32); the stator windings (40, 41, 42, 43) are connected to the speed variator (62).

With reference to table 1, fig. 1 and 2, the car can steer with the 4 wheels by 90 degrees thanks to the control, if necessary, of the rotation of the steering column (14) (16) around the pin (18) of the steering control; and the same in synchronism, but in reverse for the rear steering (15); to obtain this, the wheels (2, 3, 4, 5) are positioned externally with respect to the frame (1) of the car; the springs (21, 22, 25, 26) keep the steering columns (14) centered in gear (16) and the rear one, whose circular trajectories are illustrated in dashed lines, around the pins (18,19); the opposite rotation synchronism between the front and rear columns takes place either mechanically (in particular by means of a crossed chain or opposite sprockets), or electrically. With reference to table 1, fig. 3, each of the 4 wheels (2, 3, 4, 5) internally has the stator (40, 41, 42, 43) composed of many windings suitable for creating the speed variation through the control panel; the external rotors (6, 7, 8, 9) therefore have a variable speed; in order not to damage the delicate rotor and stator windings, elastomer rings (10, 11, 12, 13) interrupted by inclined partitions (50, 51, 52, 53), having the dual function of eliminating resonances due to the asymmetrical response, and of assigning a propulsive thrust to each protuberance of the asperities of the ground.

In table 1, fig. 1, the hybrid control of the car is shown: each wheel (2, 3, 4, 5) has its own group of stator windings (40, 41, 42, 43) connected to the electric motor (29) by means of the electric control connected to in turn to the accumulator (31) and to the converter (32) designed to contain voltage surges; the electric motor (29) is mechanically connected to the internal combustion motor (30).

In table 2 illustrates the high tech hybridization drive mechanism (63); with the so-called VMS (vehicle maneuvering system) which integrates in a single component the vehicle management functions (functionality and safety), with the control of the electric machine (inverter), the battery charge (31) plugin (64), the DC / DC converter (power supply for services) very similar to that of Piaggio.

While the endothermic engine (29) is mechanically connected to the electric generator (30) in turn connected to the lithium electric accumulator (31), and to the converter (32) designed to absorb voltage jumps, the accumulator (31) it is connected through the plug (64) of the plug-in to the electric current for recharging said accumulator; the VMS (62) in turn connects the accelerator (60) of the combustion engine (29) to the contactor (61) of the various coils of the motors (6, 7, 8, 9) located inside the wheels, so as to optimize vehicle accelerations and speeds.

ADVANTAGES SUCH AS TO ASSURE THE FOUND INNOVATION AND INVENTIVE ACTIVITY.

1- Thanks to the electric wheels, it is possible to turn at 90 ° for easy parking or for a turnaround;

2- at the start, there is a good acceleration;

3- the elimination of the differential allows greater grip, especially on mud or snow;

4- during braking and descending, the accumulator is recharged;

5- ecological in the city, smooth driving on the highway;

6- great speed for overtaking, with the wheel motors in synergy with the internal combustion engine;

7- great saving of the braking system;

8- lower consumption of both fuel and electricity (also because the electric motor has a much higher efficiency than the internal combustion one).

9- cost halved compared to the purely electric vehicle, thanks to the lower cost of the lithium battery.

10- the inclined fins in the elastomer of the wheels give the car a propulsive thrust at every protuberance of the ground.

11- only the tire, with its small mass, skips in the presence of rough terrain, thus saving suspension and vehicle.
