Abstract:
The invention relates to a braking device, which mainly comprises a pneumatic servomotor (1) and a master cylinder (2), the servomotor comprising in particular a rigid casing (10), a moving partition wall (11), front and rear chambers (101, 102), and a pneumatic piston (12), and the master cylinder (2) comprising more particularly primary and secondary pistons (221, 222) defining primary and secondary pressure chambers (241, 242), and an actuating rod (23) which controls the primary piston (221). The master cylinder (2) is integral with the pneumatic piston (12) and slidingly fitted inside the front chamber (101), whereas the actuating rod (23) is hollow, integral with the rigid casing (10) and communicates with the primary pressure chamber (241), the secondary piston (222) is traversed, in an airtight manner, by a passage (25) communicating with the secondary chamber (242), and extending through the primary chamber (241) and the actuating rod (23), while being stationary in relation to the rigid casing (10).
