Abstract

Pour refroidir un double embrayage humide (10) comportant un premier ensemble de friction humide (E1) entourant un deuxième ensemble de friction humide (E2), on injecte un liquide de refroidissement dans une partie du double embrayage humide plus proche de l’axe de révolution commun (100) que les ensembles de friction humide (E1, E2). Dans un premier régime de fonctionnement (10), le premier ensemble de friction humide (E1) est ouvert et le deuxième (E2) fermé, et le liquide de refroidissement est canalisé de façon qu’un premier flux de liquide de refroidissement traverse le premier ensemble de friction humide (E1) sans traverser la deuxième friction humide (E2), et qu’un deuxième flux de liquide de refroidissement traverse en série le deuxième ensemble de friction humide (E2) puis le premier ensemble de friction humide (E1), avec un ratio (Q) entre débit du premier flux (D1_1) et débit du deuxième flux (D1_2) supérieur à 20%. (Figure de l’abrégé : Fig. 4)
