Title (EN) PNEUMATICALLY ADJUSTABLE CONTINUOUSLY VARIABLE TRANSMISSION
(FR) BOÎTE DE VITESSES CVT À RÉGLAGE PNEUMATIQUE
(DE) PNEUMATISCH VERSTELLBARES CVT-GETRIEBE
Abstract:
(EN) The invention relates to a continuously variable transmission (CVT) comprising: a V-pulley (2) that includes at least one axially movable conical disk (21); an adjusting device (5) for adjusting a position of the axially movable conical disk (21); and a control unit (6) designed to actuate the adjusting device (5) in order to change the position of the axially movable conical disk (21). The control unit (6) comprises a pneumatic pressure element (50) in order for the axially movable conical disk (21) to be adjusted by a pneumatic force.
(FR) La présente invention concerne une boîte de vitesses CVT comprenant une paire de poulies à flasques coniques (2) comportant au moins une poulie à flasque conique (21) mobile axialement ; un dispositif de réglage (5), servant à régler une position de la poulie à flasque conique (21) mobile axialement, ainsi qu'une unité de commande (6) conçue pour actionner le dispositif de réglage (5) afin de modifier la position de la poulie à flasque conique (21) mobile axialement, ladite unité de commande (6) comprenant un boîtier sous pression (50) pneumatique pour déplacer la poulie à flasque conique (21) mobile axialement au moyen d'une force pneumatique.
(DE) Die vorliegende Erfindung betrifft ein CVT-Getriebe, umfassend ein Kegelscheibenpaar (2) mit wenigstens einer axial beweglichen Kegelscheibe (21); eine Stelleinrichtung (5) zur Verstellung einer Position der axial beweglichen Kegelscheibe (21), und eine Steuereinheit (6), welche eingerichtet ist, die Stelleinrichtung (5) zu betätigen, um die Position der axial beweglichen Kegelscheibe (21) zu verändern, wobei die Steuereinheit (6) eine pneumatische Druckdose (50) umfasst, um die axial bewegliche Kegelscheibe (21) mittels einer Pneumatikkraft zu verstellen.
