COMPACT DOUBLE WET CLUTCH MECHANISM

The invention concerns a double wet clutch mechanism (1) for a motor vehicle transmission, comprising: - first and second clutches (E1, E2) respectively of the type with multiple discs rotating about an axis of rotation (O), controlled so as to selectively couple a drive shaft to a first driven shaft (A1) and to a second driven shaft (A2) via a common torque input disc carrier (10), the first clutch (E1) being arranged radially beyond the second clutch (E2); - a clutch control system (100) comprising first and second actuating pistons (110, 120) designed to control the first and second clutches (E1, E2); - first and second elastic return devices (60, 70) associated with the first and second actuating pistons arranged bearing on the input disc carrier, and - a guide bearing (80) supporting the input disc carrier (10) with respect to the actuation system (100), the clutches, the elastic return devices and the guide bearing being concentric.
