A clutch mechanism intended to be installed between an engine and a transmission of a motor vehicle. The clutch mechanism is configured to be installed on the transmission () in two steps and by means of an axial locking system for axial locking of the control system () with respect to a clutch (). The axial locking system comprises a first axial locking element () for implementing at least an axial retention between the control system () and the transmission (), and a second axial locking element () for implementing at least an axial retention between the clutch () and a shaft (A, A) of the transmission, and a means for rotational coupling of a clutch support () with respect to the control system (), the rotational coupling means being different from the axial locking system.

Clutch mechanism and method for installing such mechanism on transmission drivetrain

A clutch mechanism designed to be installed between an engine and a motor vehicle transmission, wherein the clutch mechanism includes at least one cooling duct arranged to make a cooling fluid circulate toward the clutch, wherein each cooling duct includes an axially extending part and at least one radially extending part, the axially extending part of each cooling duct is situated radially between a transmission shaft and an interior face of the clutch support, and at least one radially extending part of each cooling duct is situated axially between the support bearing and the output hub.

Cooling system for clutch mechanism

A hydraulic control system () for a dual wet clutch ()has two clutches (). The hydraulic control system () includes a housing () having an internal tube () extending axially around the axis X and configuring an internal space intended for passage of the two input shafts () of a gearbox, and first and second annular chambers () concentric around the axis X and disposed radially around the internal tube (). The hydraulic control system () further includes first and second annular pistons (), which are respectively mounted axially slidingly inside the first and second annular chambers (). Each of the first and second annular pistons () carrying a rotating stop (). The internal tube () has at least one flow conduit () for a cooling fluid, intended to direct the cooling fluid to the clutches ().
