There is described a driving unit (1), comprising: a motor (10), a driven shaft (2) driven by the motor, and a transmission device (20) coupled between the motor and the output shaft and having one input shaft (21) and two rotational output members (22) and (23), wherein the ratio of transmission from the input shaft (21) to the first rotational output member (22) differs from the ratio of transmission from the input shaft (21) to the second rotational output member (23). The first rotational output member (22) is coupled to the motor housing (11) via a slip coupling (30). A helical spring (60) arranged so as to be coaxial to the motor presses the first rotational output member (23) against the motor housing (11), wherein that helical spring (60) engages the motor housing (11) via a pressure ring (50). This pressure ring (50) has a helical channel (52) for receiving the helical spring (60). The pressure ring (50) is rotatable to enable setting the maximum value of the moment that can be supplied to the output shaft (2).
L'invention concerne une unité motrice (1) qui comprend un moteur (10), un arbre secondaire (2) actionné par le moteur, et un organe de transmission (20) accouplé entre le moteur et l'arbre secondaire, et comportant un arbre de commande (21) et deux éléments rotatifs de sortie (22, 23). Le rapport de transmission entre l'arbre de commande (21) et le premier élément rotatif de sortie (22) est différent du rapport de transmission entre l'arbre de commande (21) et le second élément rotatif de sortie (23). Le premier élément rotatif de sortie (22) est accouplé au carter du moteur (11) via un accouplement à glissement (30). Un ressort hélicoïdal (60), coaxial avec le moteur, presse le premier élément rotatif de sortie (23) contre le carter du moteur (11), ledit ressort (60) entrant en contact avec ce dernier via un anneau de pression (50). Celui-ci (50) comporte un canal hélicoïdal (52) destiné à recevoir le ressort hélicoïdal (60). L'anneau de pression (50) est rotatif, ce qui permet de donner la valeur maximum au couple pouvant être fourni à l'arbre secondaire (2).
