摘要 |
The servomotor comprises a piston (22) mounted between a control rod (24) activated by a brake pedal and a push rod (34) activating the piston of a brake master cylinder. Means for increasing the braking assistance during emergency braking comprise an axially mounted cylindrical socket (46) sliding inside the piston held in the rest position by locking means (58). It is released in order to push back the valve (56) of a three-way valve and increase the atmospheric air supply to the servomotor when the control rod is displaced at a greater speed than a predetermined value.
