Title
(EN) MULTIDISC-TYPE WET DOUBLE CLUTCH
(FR) DOUBLE EMBRAYAGE HUMIDE DE TYPE MULTIDISQUES
Abstract
(EN) Wet double clutch (1) for a torque transmission system, comprising: a torque input web (2) arranged to be kinematically linked with a heat engine around an axis of rotation (X); a first clutch (E1) and a second clutch (E2), both of the multi-disc type, arranged radially one above the other and aligned in a plane (P) perpendicular to the axis of rotation (X); a torque input disc carrier (10, 20) common to the first clutch (E1) and the second clutch (E2) and connected for conjoint rotation with the torque input web (2), said carrier supporting a drive ring (80) arranged to engage with the rotor of the rotating electric machine, the wet double clutch being guided in rotation relative to the torque transmission system by means of axial and radial bearings (41, 42, 43, 44) arranged on either side of the plane (P).
(FR) Double embrayage humide (1) pour système de transmission de couple comprenant : - un voile d'entrée de couple (2) agencé pour être lié cinématiquement avec un moteur thermique autour d'un axe de rotation (X); - un premier embrayage (E1) et un deuxième embrayage (E2) respectivement de type multidisques, disposés radialement l'un au-dessus de l'autre et alignés selon un plan (P) perpendiculaire à l'axe de rotation (X), - un porte-disques d'entrée (10, 20) de couple commun au premier embrayage (E1) et au deuxième embrayage (E2) solidaire en rotation avec le voile d'entrée de couple (2), supportant une couronne d'entrainement (80) agencée pour engrener avec le rotor de la machine électrique tournante, le double embrayage humide étant guidé en rotation par rapport au système de transmission de couple par l'intermédiaire de paliers axiaux et radiaux (41, 42, 43, 44) disposés de part et d'autre du plan (P).
