Abstract: A suspension and traction system (MC) is described 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). A rotary electric motor (12) operates two rotors (14, 16) independently controllable from one another to supply two epicycloidal mechanisms (20, 30) whose 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) of the frame.

Abstract: An electric motor (MC) is described comprising a rotor (100) rotatable about a rotation axis (X), a stator comprising a circular series of windings for creating a magnetic field through which to rotate the rotor; a support provided with a circular series of seats for housing the windings; an element (40, 50), mounted between a winding and a wall of the respective seat which houses it, configured to conduct heat from the winding towards the outside of the stator in order to dissipate the heat.

Abstract: The device has an electrical traction machine (20) suspended to a body of a hybrid or electric motorization vehicle and providing engine torque (CM) applied to rear wheels (3, 4). A mechanical link is provided between the machine and a deformable crossmember (2) to transmit torque effect (CR) with the engine torque to the crossmember for descending the rear wheels with respect to the body of the vehicle and for creating anti-squat effect during acceleration in electric propulsion of the vehicle. The link is provided with a connection shaft (30) connected to two levers (21, 33).

Abstract: A suspension system (20) is described for vehicle with a frame, comprising an element (R, 12) propulsive by rolling on the ground; two units (12a, 12b) adapted to impart a torque to the propulsive element that are controllable independently of one another, where the two units are movable relative to the propulsive element independently from one another and rigidly connectable to the frame at one same point (P). By moving one or each unit relative to the propulsive element the distance between the latter and said point is made to vary.
