Abstract: front page image
(EN) A motor-vehicle transmission with a double clutch coupling device comprises an outer housing (3) and an inner housing (23) defining a closed sealed chamber, within which two clutch couplings (11, 12) are arranged having multiple plates immersed in a cooling lubricant fluid. The transmission comprises a fluid actuator member (18, 20) for each clutch coupling (11, 12). At least one of said fluid actuator members is an annular hydraulic cylinder (20) coaxially mounted around the concentric primary shafts (5, 6) of the transmission. This annular cylinder is supported by an annular flange (22) secured to the main supporting structure (2) of the transmission. The inner housing (23) is carried by said flange (22) which supports the annular hydraulic cylinder (20).
