Abstract

L'invention concerne un mécanisme de commande pour boîtes de changement de vitesses de véhicules automobiles. Ledit mécanisme comporte des embrayages ainsi qu'une tige mobile longitudinalement avec une fourchette, des tiges de poussée et des coulisses. Les tiges de poussée sont guidées par des épaulements arrondis et des goujons à rotule des coulisses ainsi que par des blocs qui s'appuient contre une tige de commande guidée dans le carter. La tige de commande et les tiges de poussée sont superposées perpendiculairement à l'arbre d'entraînement, tout en se prolongeant parallèlement à ce dernier. Application aux transmissions de véhicules automobiles.The invention relates to a control mechanism for gearboxes of motor vehicles. Said mechanism comprises clutches as well as a longitudinally movable rod with a fork, push rods and slides. The push rods are guided by rounded shoulders and ball studs on the slide rails as well as by blocks which rest against a control rod guided in the housing. The control rod and the push rods are superimposed perpendicular to the drive shaft, while extending parallel to the latter. Application to motor vehicle transmissions.
