Abstract
A hydraulic control system (21) for a dual wet clutch (1)has two clutches (4, 5). The hydraulic control system (21) includes a housing (41) having an internal tube (42) extending axially around the axis X and configuring an internal space intended for passage of the two input shafts (2, 3) of a gearbox, and first and second annular chambers (43, 44) concentric around the axis X and disposed radially around the internal tube (42). The hydraulic control system (21) further includes first and second annular pistons (45, 46), which are respectively mounted axially slidingly inside the first and second annular chambers (43, 44). Each of the first and second annular pistons (45, 46) carrying a rotating stop (49, 50). The internal tube (42) has at least one flow conduit (55) for a cooling fluid, intended to direct the cooling fluid to the clutches (4, 5).
