The present invention relates to a removable electric propulsion system (1) for a rolling object, propulsion system (1) comprising a chassis (2) provided with at least one wheel (3) driven by an electric machine, at least one non-driven wheel (4) and at least one means for coupling electric propulsion system (1) to the rolling object. The coupling means comprises at least one means providing combined and simultaneous gripping and lifting of at least one wheel of the rolling object, and the combined and simultaneous gripping and lifting means comprises a frame (23), at least one arm (24) extendable in a longitudinal direction (x) and connected to frame (23), at least one tilt element (22) and at least one push device (20), one among tilt element (22) and push device (20) being connected to said extendable arm (24) and the other to chassis (2), said push device (20) being capable of driving at least one wheel of the rolling object along said longitudinal direction (x) into said at least one tilt element (22), said tilt element (22) being capable of tilting about an axis of substantially transverse direction (21). The invention also relates to a coupling method and to a device for coupling a propulsion system to the rolling object.
1) A removable electric propulsion system for a rolling object, the propulsion system comprising a chassis provided with at least one wheel driven by an electric machine, at least one non-driven wheel and at least one means for coupling the electric propulsion system to the rolling object, characterized in that the coupling means comprises at least one means for combined and simultaneous gripping and lifting at least one wheel of the rolling object, and in that the combined and simultaneous gripping and lifting means comprises a frame, at least one arm extendable in a longitudinal direction and connected to frame, at least one tilt element and at least one push device, one among tilt element and push device being connected to the extendable arm and the other to frame, the push device being capable of driving at least one wheel of rolling object along the longitudinal direction (x) into the at least one tilt element, the tilt element being capable of tilting about an axis of substantially transverse direction.
