Abstract

La présente invention concerne un appareil de transmission haute puissance à sorties multiples à fixation indépendante, comprenant un corps de boîte (1), un arbre d'entraînement (2) et un arbre de sortie (3) montés sur le corps de boîte (1), ainsi qu'un arbre intermédiaire (7-c) avec un engrenage de transmission (7-c-1). L'arbre d'entraînement (2) comprend un arbre d'entrée d'entraînement (2a) et un arbre de sortie d'entraînement (2b) disposés de manière coaxiale, ledit arbre d'entrée d'entraînement (2a) étant doté d'un engrenage d'entrée d'entraînement (4). L'arbre de sortie (3) est engrené de manière mobile avec un engrenage d'entrée (5), ledit engrenage d'entrée (5) étant relié en transmission à l'engrenage d'entrée d'entraînement (4) par l'intermédiaire de l'engrenage de transmission (7-c-1). L'arbre de sortie d'entraînement (2b) et l'arbre de sortie (3) sont respectivement reliés en transmission à l'engrenage d'entrée d'entraînement (4) et à l'engrenage d'entrée (5) par l'intermédiaire d'un mécanisme à fourchette d'embrayage avec un ensemble de mise en prise. Par l'intermédiaire de l'engrenage d'entrée (5) monté mobile sur l'arbre de sortie (3), l'énergie de l'arbre actif (2) est transmise à l'engrenage d'entrée (5). Par l'intermédiaire du mécanisme à fourchette d'embrayage doté de l'ensemble de mise en prise, l'énergie de l'engrenage d'entrée (5) et l'énergie de l'engrenage d'entrée d'entraînement (4) sont respectivement transmises à l'arbre de sortie (3) et à l'arbre de sortie d'entraînement (2). L'appareil selon l'invention présente une structure simple, un coût réduit, et il permet d'obtenir une sortie indépendante et une sortie simultanée des arbres de sortie par commande du mécanisme à fourchette d'embrayage. De plus l'entrée et la sortie des arbres sont réversibles de manière à assurer une grande applicabilité.
