<p>Braking system comprising a brake booster (200) with electric motor driving the push rod (130) of the piston of the master cylinder (100) via a ball-screw connection and actuated by a control rod (230). In the casing (201) connected to the master cylinder (100), the brake booster (200) comprises an actuator piston (220) guided in translational movement by at least two guide pins (311) which are parallel to the axis (XX) of the master cylinder (100) and which is driven in translational movement by a ball screw (225, 226) of which the screw (225), driven by the motor (210), is offset with respect to the axis (XX) of the master cylinder (100). The screw collaborates with a nut (226) translationally as one with the actuator piston (220), and a bore (221) of the actuator piston (220) receives a boost piston (250) equipped with a reaction disc (240) and with a plunger piston (232) connected to the control rod (230).</p> |
