Abstract
(DE)
Es wird eine Anordnung mit zumindest einem hydraulisch über einen Betätigungsdruck betätigbaren Schaltelement (1, 1A), welches koaxial zu einer Getriebewelle (2, 26) in einem Getriebegehäuse (3) eines Automatikgetriebes eines Fahrzeuges angeordnet ist, und mit zumindest einem Sperrventil zum Sperren und Freigeben der Schaltposition des Schaltelementes (1, 1A) vorgeschlagen, wobei das Sperrventil mit einem separaten Steuerdruck beaufschlagbar ist und wobei das Sperrventil radial innerhalb des Schaltelements (1, 1A) im Getriebegehäuse (3) angeordnet ist.
(EN)
The invention relates to an assembly, comprising at least one shifting element (1, 1A) that can be hydraulically actuated by means of an actuating pressure, which at least one shifting element is arranged coaxially to a transmission shaft (2, 26) in a transmission housing (3) of an automatic transmission of a vehicle, and comprising at least one shut-off valve for blocking and enabling the shifting position of the shifting element (1, 1A), wherein a separate control pressure can be applied to the shut-off valve and wherein the shut-off valve is arranged radially within the shifting element (1, 1A) in the transmission housing (3).
(FR)
L'invention concerne un dispositif comprenant au moins un élément de changement de rapport (1, 1A) hydraulique pouvant être actionné par le biais d'une pression d'actionnement, lequel est disposé de manière coaxiale par rapport à un arbre de boîte de vitesses (2, 26) dans un carter (3) d'une boîte de vitesses automatique d'un véhicule, et comprenant au moins une vanne d'arrêt servant à bloquer et à libérer la position de changement de rapport de l'élément de changement de rapport (1, 1A). La vanne d'arrêt peut être chargée par une pression de commande séparée et la vanne d'arrêt est disposée dans le sens radial à l'intérieur de l'élément de changement de rapport (1, 1A) dans le carter de boîte de vitesses (3).
