Embodiment Construction

[0070] The system MC shown serves to rotate a propulsion element in the form of a wheel R. The wheels R move an associated vehicle (not shown) by rolling over the terrain T. System MC is for example duplicated on all wheels of the vehicle.

[0071] System MC includes a rotating electric motor 12 formed by a common stator 12S and two independent rotors 14 , 16 . The electrical part of the electric motor 12 is, for example, of known type.

[0072] The rotors 14, 16 are coaxial and have a common axis of rotation indicated by X, which is fixed relative to the frame.

[0073] The rotors 14, 16 may also be mounted one inside the other (for example, they are two concentric sleeves) and transmit torque from the motor to the sun gear 24 and the sun gear belonging to the respective planetary gear mechanism 20, 30 respectively. 34.

[0074] The planetary gear mechanism 20 (30) comprises, in known manner, a central sun gear 24 (34) meshing with a planetary gear 26 (36), which in turn ...

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.

Description

technical field [0001] The present invention relates generally to traction and suspension systems, particularly in wheeled electric vehicles. Background technique [0002] In the latest generation of electric vehicles, see eg WO2015155670, two electric motors are controlled independently of each other, not only to provide propulsion torque to the wheels, but also to vary their distance from the frame. [0003] WO2015155670 describes a motor wheel as a specific example, while in some applications it is preferable to mount the electric motor on the frame, for example to simplify the structure of the vehicle. Therefore, it would be useful to improve the embodiment of WO2015155670 for this situation. Furthermore, the system in WO2015155670 encounters difficulties if one wishes to integrate the system into an existing vehicle frame structure. Contents of the invention [0004] It is therefore desirable to propose improvements to WO2015155670 to solve one or more of these prob...
