Title (EN) METHOD AND FLUID SYSTEM FOR FLUIDICALLY ACTUATING TWO SUB-CLUTCHES
(FR) PROCÉDÉ ET SYSTÈME DE FLUIDE POUR L’ACTIONNEMENT FLUIDIQUE DE DEUX EMBRAYAGES PARTIELS
(DE) VERFAHREN UND FLUIDSYSTEM ZUM FLUIDISCHEN BETÄTIGEN VON ZWEI TEILKUPPLUNGEN
Abstract:
(EN) The invention relates to a method for fluidically actuating two sub-clutches (15, 16) of a dual-clutch transmission and a secondary fluidic load (18) using two pump actuators (11, 12) in a fluid system (10). The aim of the invention is to simplify the actuation of two sub-clutches. This is achieved in that one of the sub-clutches (15, 16) is held in a current state for a duration such that both pump actuators (11, 12) can be used for other purposes during said duration, in particular for the at least one secondary fluidic load (18).
(FR) L’invention concerne un procédé pour l’actionnement fluidique de deux embrayages partiels (15, 16) d’une boîte de vitesses à double embrayage et d’un consommateur fluidique (18) secondaire, au moyen de deux actionneurs de pompe (11, 12) dans un système de fluide (10). Pour simplifier l’actionnement de deux embrayages partiels, un des embrayages partiels (15, 16) est maintenu dans un état actuel pendant une durée de temps, de sorte que, pendant cette durée de temps, les deux actionneurs de pompe (11, 12) peuvent être utilisés autrement, en particulier pour l’au moins un consommateur fluidique (18) secondaire.
(DE) Die Erfindung betrifft ein Verfahren zum fluidischen Betätigen von zwei Teilkupplungen (15, 16) eines Doppelkupplungsgetriebes und von einem sekundären fluidischen Verbraucher (18), mit Hilfe von zwei Pumpenaktoren (11,12) in einem Fluidsystem (10). Um das Betätigen von zwei Teilkupplungen zu vereinfachen, wird eine der Teilkupplungen (15, 16) für eine Zeitdauer in einem aktuellen Zustand gehalten, so dass während dieser Zeitdauer beide Pumpenaktoren (11, 12) anderweitig, insbesondere für den mindestens einen sekundären fluidischen Verbraucher (18), verwendet werden können.
