Abstract

Le problème à résoudre dans le cadre de cette invention concerne la mise en place d'un dispositif de transmission de puissance dans lequel une surface de came et l'autre surface de came d'une came permettant d'obtenir un contact par pression ou d'une came pour dispositif limiteur de rétro-couple sont formées respectivement sur des bords périphériques d'un élément d'embrayage et d'un élément de pression. Lors de la formation des surfaces de came, les caractéristiques de came ciblées sont obtenues de manière fiable même si les largeurs des surfaces de came sont fixées à la hausse ou sont utilisées sur une longue période. Le solution proposée consiste à mettre en place un dispositif de transmission de puissance qui possède un logement d'embrayage (2), des disques d'embrayage d'entraînement (6), des disques d'embrayage entraînés (7) capables d'être comprimés contre ou séparés des plaques d'embrayage d'entraînement (6), un élément d'embrayage cylindrique creux sensiblement circulaire (4), un élément de pression (5), et la came permettant d'obtenir un contact par pression ou la came pour dispositif limiteur de rétro-couple. Une surface de came (11a, 11b) et l'autre surface de came (12a, 12b) qui forment la came permettant d'obtenir un contact par pression ou la came pour dispositif limiteur de rétro-couple sont formées sur des éléments séparés (11, 12) en matériau dur tel que l'acier ou le titane.
