ELECTRIC AUXILIARY DRIVE FOR A TRAVELLING DEVICE PRIMARILY DRIVEN, IN PARTICULAR DRAWN OR PUSHED, BY HUMAN OR ANIMAL POWER

摘要

FIELD OF THE INVENTION The present invention relates to an electric auxiliary drive driven primarily by human or animal force, in particular a tensioned or gyratory device, which, in the required propulsion force according to the invention, is designed as an auxiliary drive with a low-value, especially negative, required propulsion force, and for a first-hand drive force with a measuring device (9). , moreover, in the event of exceeding a predetermined primary drive force, and in the event of its occurrence, by increasing or decreasing the produced spark arrestor, or by reducing or increasing the braking head of the generating ring, the predetermined primary driving force is provided with a regulating control unit (7). ŕ
