- the deflector 500 is provided with a holding member interposed between the deflector 500 and the first axial elongation bearing surface 107 of the first output disk carrier 110.
- the holding member 502 is provided to minimize a deflection of the deflector 500 and prevent the deflector 500 from moving away from the second axial elongation range 207 by a maximum target angular value, in particular due to excessive vibrations of the deflector. mechanism with two wet clutches 10.
- the holding member 502 is for example formed of an elastic return member.
- the second axial elongation range 207 comprises a plurality of passages 2071 which allow the hydraulic fluid to pass through the second axial elongation bearing surface 207, in other words to pass on either side of the second axial elongation bearing surface 207, the deflector 500 then impeding a flow of hydraulic fluid to the first clutch 100.
- the deflector 500 is provided with a plurality of stiffeners 501.
- Each stiffener 501 is provided to reinforce a mechanical strength of the deflector 500.
- the stiffener 501 is shaped like a rib. axial elongation which is formed substantially parallel to the axis of rotation O and / or which extends from a front end of the deflector 500 and towards its rear end.
- the stiffener 501 protrudes radially outwardly from the outer face of the baffle 500 and extends from the leading edge 505 to a trailing edge 506 of the baffle 500.
- the baffle 500 is free of stiffener.
