Title (EN) ACTUATING DEVICES FOR SYSTEMS SUCH AS CLUTCHES OR GEARBOXES
(FR) DISPOSITIFS D'ACTIONNEMENT DE SYSTEMES TELS QUE LES EMBRAYAGES OU LES BOITES DE VITESSES
Abstract:
(EN) A cyclic actuating device for systems such as clutches or gearboxes, comprising an input shaft (1), an output shaft and a dog interlocking system therebetween. The device includes a first rotary member (5) driven by the input shaft, a second rotary member (6) drivable by the first rotary member, and a third rotary member (7) driven by the second rotary member and arranged to drive the output shaft, said rotary members being movable with respect to one another; a control member (4) for causing mutual engagement of the first and second rotary members at the start of the cycle; and a first resilient means (8) which, as it is decompressed, presses the control member in a direction in which it causes mutual engagement of said first and second rotary members at the start of the cycle. Said rotary members are arranged to return the first resilient means to the compressed position at the end of the cycle.
(FR) L'invention a pour objet un dispositif d'actionnement cyclique de systèmes tels que les embrayages ou les boîtes de vitesses, du type comportant un arbre d'entrée (1) et un arbre de sortie, et un système de solidarisation à crabots entre les deux arbres. Il comprend: un premier organe rotatif (5) entraîné par l'arbre d'entrée, un deuxième organe rotatif (6) susceptible d'être entraîné par le premier organe rotatif, et un troisième organe rotatif (7) entraîné par le deuxième organe rotatif et agencé pour entraîner l'arbre de sortie, lesdits organes rotatifs étant mobiles les uns relativement aux autres; un organe de commande (4) susceptible d'amener en engagement, en début de cycle, les premier et deuxième organes rotatifs; des premiers moyens élastiques (8) pour presser en se décomprimant l'organe de commande dans une direction où il amène, en début de cycle, lesdits premier et deuxième organes rotatifs en engagement; lesdits organes rotatifs étant agencés pour ramener, en fin de cycle, lesdits premiers moyens élastiques en position comprimée.
