摘要： A torque transmission assembly provided in a motor vehicle transmission. The torque transmission assembly comprises at least a clutch housing and a torque transmission module including: a cover, a wet dual-clutch mechanism rotatable about an axis, and a clutch casing comprising, in whole or in part, an oil dispensing device for supplying oil to the wet dual clutch. The cover and the clutch casing are assembled so as to form a housing defining a cavity in which the wet dual-clutch mechanism is received at least in part, and wherein the clutch casing is received, in whole or in part, in the clutch housing, and the cover comprises a first bearing surface capable of resting on an internal combustion engine.

摘要： The invention relates to a clutch mechanism intended to be installed between an engine and a transmission of a motor vehicle, the mechanism being configured to be installed on a transmission (400) in two steps and by means of a system for axial locking of the control system (300) with respect to the clutch (100, 200). The axial locking system comprises a first axial locking element (304, 302) for implementing at least an axial retention between the control system (300) and the transmission (400), and a second axial locking element (600) for implementing at least an axial retention between the clutch (100, 200) and a shaft (A1, A2) of the transmission, and a means for rotational coupling of the clutch support (500) with respect to the control system (300), the rotational coupling means being different from the axial locking system.
