(EN) HYDRAULIC CIRCUIT FOR ACTUATING A HYBRID TRANSMISSION
(FR) CIRCUIT HYDRAULIQUE POUR ACTIONNER UNE TRANSMISSION HYBRIDE
Abstract
(DE)
Hydraulikkreis (1) zur Betätigung eines Hybridgetriebes umfassend eine Pumpe (2) zum Fördern eines Hydraulik-Mediums in eine Speichereinheit (7), wobei über die Speichereinheit (7) eine Versorgungsleitung (3) mit Hydraulikmedium beaufschlagbar ist, wobei über die Versorgungsleitung (3) zumindest ein erster Teilkreis (5, 5') des Hydraulikkreises (1) und zumindest ein zweiter Teilkreis (6) des Hydraulikkreises (1) mit Hydraulik-Medium beaufschlagbar sind, wobei der erste Teilkreis (5, 5') über ein erstes Teilkreisventil (8, 8') mit der Versorgungsleitung (3) verbindbar ist und der zweite Teilkreis (6) über ein zweites Teilkreisventil (9) mit der Versorgungsleitung (3) verbindbar ist und wobei über den ersten Teilkreis (5, ') zumindest eine erste Kupplung (18, 18') und zumindest ein erster Gangsteller (21, 21') betätigbar sind und über den zweiten Teilkreis (6) zumindest eine zweite Kupplung (19) und zumindest ein zweiter Gangsteller (22, 23) betätigbar sind.
(EN)
The invention relates to a hydraulic circuit (1) for actuating a hybrid transmission, comprising a pump (2) for pumping a hydraulic medium into a storage unit (7). Hydraulic medium can be supplied to a supply line (3) via the storage unit (7), and hydraulic medium can be supplied to at least one first sub-circuit (5, 5') of the hydraulic circuit (1) and at least one second sub-circuit (6) of the hydraulic circuit (1) via the supply line (3). The first sub-circuit (5, 5') can be connected to the supply line (3) via a first sub-circuit valve (8, 8'), and the second sub-circuit (6) can be connected to the supply line (3) via a second sub-circuit valve (9). At least one first clutch (18, 18') and at least one first gear selector (21, 21') can be actuated via the first sub-circuit (5, 5'), and at least one second clutch (19) and at least one second gear selector (22, 23) can be actuated via the second sub-circuit (6).

L’invention concerne un circuit hydraulique (1), destinée à actionner une transmission hybride, comprenant une pompe (2) destinée à transporter un fluide hydraulique dans une unité de stockage (7). Un conduit d'alimentation (3) peut être alimenté en fluide hydraulique par l'unité de stockage (7). Au moins un premier circuit partiel (5, 5') du circuit hydraulique (1) et au moins un deuxième circuit partiel (6) du circuit hydraulique (1) peuvent être alimentés en fluide hydraulique par le conduit d'alimentation (3). Le premier circuit partiel (5, 5') peut être raccordé au conduit d'alimentation (3) par une première vanne de circuit partiel (8, 8') et le deuxième circuit partiel (6) peut être raccordé au conduit d'alimentation (3) par une deuxième vanne de circuit partiel (9) et au moins un premier embrayage (18, 18') et au moins un premier sélecteur de vitesses (21, 21') peuvent être actionnés le biais du premier circuit partiel (5') et au moins un deuxième embrayage (19) et au moins un deuxième sélecteur de vitesses (22, 23) peuvent être actionnés par le biais du deuxième circuit partiel (6).
