Abstract:
(EN) The invention relates to a multi-ratio transmission provided with eight forward gears and one reverse gear, comprising an input shaft (1), an output shaft (2), three planetary gear sets (P1, P2, P3), a first and a second spur gear stage (S1, S2) which are connected to a countershaft which is arranged parallel to the longitudinal axis of the planetary gear sets (P1, P2, P3) and which forms the output shaft (2) of the transmission, and at least five shift elements (03, 15, 24, 45, 46, 56, 58) and eight rotatable shafts (1, 2, 3, 4, 5, 6, 7, 8), wherein the input shaft (1) is connected to the planet carrier of the first planetary gear set (P1) and can be detachably connected by means of a first clutch (15) to the fifth shaft (5) which is connected to the ring gear of the second planetary gear set (P2) and which can be detachably connected by means of a third clutch (58) to the eighth shaft (8) which is connected to the sun gear of the third planetary gear set (P3).
(FR) Boîte de vitesses multi-étagée pourvue de huit rapports de marche avant et d'un rapport de marche arrière, comprenant un arbre d'entrée (1), un arbre de sortie (2), trois trains planétaires (P1, P2, P3), un premier et un deuxième étage de pignons cylindriques (S1, S2) en liaison avec un arbre intermédiaire qui est monté en parallèle à l'axe longitudinal des trains planétaires (P1, P2, P3) et qui forme l'arbre de sortie (2) de la boîte de vitesses, ainsi qu'au moins cinq éléments de commutation (03, 15, 24, 45, 46, 56, 58) et huit arbres rotatifs (1, 2, 3, 4, 5, 6, 7, 8), l'arbre d'entrée (1) étant relié au porte-satellites du premier train planétaire (P1) et pouvant être relié de manière détachable par l'intermédiaire d'un premier embrayage (15) au cinquième arbre (5), lequel est relié à la couronne du deuxième train planétaire (P2) et peut être relié de manière détachable par l'intermédiaire d'un troisième embrayage (58) au huitième arbre (8) qui est relié à la roue planétaire du troisième train planétaire (P3).
(DE) Das Mehrstufengetriebe mit acht Vorwärtsgängen und einem Rückwärtsgang umfasst eine Antriebswelle (1), eine Abtriebswelle (2), drei Planetenradsätze (P1, P2, P3), eine erste und eine zweite Stirnradstufe (S1, S2) in Verbindung mit einer parallel zur Längsachse der Planetenradsätze (P1, P2, P3) angeordneten Vorgelegewelle, welche die Abtriebswelle (2) des Getriebes bildet, sowie mindestens fünf Schaltelemente (03, 15, 24, 45, 46, 56, 58) und acht drehbare Wellen (1, 2, 3, 4, 5, 6, 7, 8), wobei die Antriebswelle (1) mit dem Steg des ersten Planetenradsatzes (PI) verbunden und über eine erste Kupplung (15) mit der fünften Welle (5) lösbar verbindbar ist, die mit dem Hohlrad des zweiten Planetenradsatzes (P2) verbunden und über eine dritte Kupplung (58) mit der mit dem Sonnenrad des dritten Planetenradsatzes (P3) verbundenen achten Welle (8) lösbar verbindbar ist.
