More Information
Summary:The drive transmission has a driving arm (10) with a cam way (40) and a driven arm (12) with a cam follower (46). The arms pivot around their parallel axes (14,16) with limited angular interval (A,B). The driving arm can have a lever (18) with a block (36) carrying the cam way. The cam way defines a path (T) with a return point (PR) oriented towards the axis of rotation of the driving arm and two sections of the pathway (48) of incurved shape which extend from the return point to abut at the ends (PE). Le dispositif de l'invention comprend un organe menant (10) portant une voie de came (40) et un organe mené (12) muni d'un suiveur de came (46) propre à coopérer avec la voie de came (40). L'organe menant (10) est réalisé sous la forme d'un levier (18) muni d'un bloc (36) portant la voie de came (40), cette dernière définissant une trajectoire limitée (T) de forme choisie présentant un point de rebroussement dirigé vers l'axe de rotation (14) de l'organe menant et deux tronçons de voie de configuration incurvée qui s'éloignent l'un de l'autre et du point de rebroussement pour aboutir à des points d'extrémité éloignés.
