ABSTRACT:
The invention relates to an assisted hydraulic braking system comprising a brake pedal (10) connected to an actuating rod (46), a pneumatic brake booster (14) comprising a front vacuum chamber (102) and a rear working chamber (104) separated by a movable deformable partition acting on a push rod, a single master cylinder (16) the piston of which is acted by the push rod, a mechanism (12) for controlling the booster (14), comprising a shutter mechanism (34) putting a first chamber (26) selectively in communication with a second chamber (30) or with the atmosphere responsive to an actuating of the brake pedal (10), a first pipeline (110) putting the first chamber (26) of the control mechanism (12) in communication with the working chamber (104) of the booster (14), a second pipeline (112) putting the second chamber (30) of the control mechanism (12) in communication with the vacuum chamber (102) of the booster (14), a second master cylinder (74) the outlets of which are connected to at least one wheel brake, the second master cylinder (74) being subjected to the actuating pressure transmitted by the actuating rod (46) and increased by the boosting pressure generated by the single master cylinder (16).
