Abstract

Le problème à résoudre dans le cadre de la présente invention concerne un dispositif de transmission pouvant être produit de manière économique sans augmentation du nombre de pièces utilisées tout en permettant une simplification de conception et une réduction de taille par rapport à l’importance d’un couple de transmission. La solution proposée consiste en un dispositif de transmission comprenant un carter d’embrayage (2), un organe d’embrayage (4) doté d’une clavette (10) disposée axialement sur sa surface périphérique extérieure et un organe de pression (5). Une première surface inclinée (10ba) est formée sur l’organe de pression (5) au niveau d’une partie terminale de côté de fixation de la partie saillante (10b) de la clavette (10), et une seconde surface inclinée (5b) correspondant à la première (10ba) est formée sur l’organe de pression (5). La première surface inclinée (10ba) et la seconde (5b) forment une came d’un limiteur de contre-couple qui, lorsque la vitesse de rotation d’un arbre de sortie dépasse celle d’un arbre d’entrée, sépare les disques d’embrayage moteurs (6) des disques d’embrayage entraînés (7).
