Title (EN) CONTINUOUSLY VARIABLE TRANSMISSION AND TRANSMISSION SYSTEM
(FR) TRANSMISSION À VARIATION CONTINUE ET SYSTÈME DE TRANSMISSION
Abstract:
(EN) The invention relates to a continuously variable transmission and a transmission system comprising said continuously variable transmission, wherein the continuously variable transmission comprises a first gear pump and a second gear pump, wherein each gear pump comprises a first gear and a second gear meshing with the first gear over an overlap distance in an overlap direction parallel to the first gear axis, wherein each gear pump further comprises an adjustment member for adjusting the pump volume, wherein the adjustment member of the first gear pump and the adjustment member of the second gear pump are interconnected by a connecting member for adjusting the pump volume of the first gear pump and the pump volume of the second gear pump in an inverse correlation to each other.
(FR) L'invention concerne une transmission à variation continue et un système de transmission comprenant ladite transmission à variation continue, la transmission à variation continue comprenant une première pompe à engrenages et une seconde pompe à engrenages, chaque pompe à engrenages comprenant un premier engrenage et un second engrenage s'engrenant avec le premier engrenage sur une distance de chevauchement dans une direction de chevauchement parallèle au premier axe d'engrenage, chaque pompe à engrenages comprenant en outre un élément de réglage permettant de régler le volume de pompe, l'élément de réglage de la première pompe à engrenages et l'élément de réglage de la seconde pompe à engrenages étant interconnectés par un élément de liaison permettant de régler le volume de pompe de la première pompe à engrenages et le volume de pompe de la seconde pompe à engrenages dans une corrélation inverse l'un par rapport à l'autre.
