Suspension and traction system for vehicles

Suspension and traction system (MC) for vehicles equipped with a frame and a propulsive element (R), which by rolling on the ground (T) is adapted to move the vehicle relative to the ground (T), comprising:

• a rotary electric motor (12) comprising two rotors (14, 16) independently controllable from one another and rotatable with respect to a stator (12s) fixed on the frame, wherein the rotors (14, 16) preferably have a common rotation axis (X),
• two epicycloidal mechanisms (20, 30) each comprising a central solar gear (24, 34), meshing with satellite gears (26, 36), meshing in turn with an outer ring gear (28, 38);
• wherein in each epicycloidal mechanism one among the solar gear (24, 34) and the satellite gears (26, 36) is coupled, respectively, to a rotor (14, 16) and the other among the solar gear (24, 34) and the satellite gears (26, 36) is connected/connectable to the propulsive element (R) to impart to it equiverse angular torque to propel the vehicle on the ground (T),
• and the two outer ring gears (28, 38) are independently movable to rotate about the respective solar gear (24, 34) and rigidly connected substantially to a same point (P) outside the epicycloidal mechanisms,
• wherein on said point (P) a thrust, determined by the coordinated angular displacement of the ring gears (28, 38) about the solar gears (24, 34), can be imparted.
