Abstract: Four-wheel electric-drive rolling vehicle (10) with front steering wheels (11) connected to a chassis (12) by means of an articulated quadrilateral front suspension group (15) and rear wheels (14) connected to said chassis (12) by means of independent, longitudinal arm suspensions (16), comprising at least a pair of electric driving motors (21), an electric motor for each of the front wheels (11) respectively, and/or an electric motor for each of the rear wheels (14), said motors (21) being fed by at least one electric accumulator group (22), through electric wire connections and at least one control board (23).

Abstract: Two-wheel vehicle (10) with an integral electric wheel-drive characterized in that it comprises two electric driving motors, a front wheel electric motor (11) and a back wheel electric motor (12) respectively, fed by at least one electric accumulator group.

Abstract: In a hybrid propulsion system for vehicles in which a first propulsion unit, of internal combustion type, transmits motion to at least one wheel of the vehicle via transmission members including at least one clutch, a second propulsion unit, of electrical type, is connected to the driven element of said clutch via means such that the motion generated by one of said propulsion units when the other is deactivated is transmitted only to the transmission members located downstream of said clutch.
