Abstract

A force transmitting arrangement, useable as force amplifier of drive arrangements, transmits the moment of a reversible electric motor, acting as a servo motor or as a drive motor, over a friction core and a looped spring cooperating therewith to an output shaft. The looped spring has a pair of outwardly bent ends, which at the outer sides thereof drive, while taking up a tension force, an output entrainment member connected to the output shaft, whereas an input entrainment member connected with a manually operated drive, for instance the steering wheel of a motor vehicle, is located between the outwardly bent ends of the looped spring.
