ANTI-LOCK BRAKING SYSTEM

摘要

ANTI-LOCK BRAKING SYSTEM A vehicle anti-lock braking system is provided having an actuator frame with a bore fluidly connected to the wheel brake and to a master cylinder via n solenoid valve. A piston, mounted within the bore, is operationally associated with a non-rotative nut which is threadably engaged by a power screw. To maximize reaction speed, a high efficiency thread is utilized between the power screw and the non-rotative nut. Therefore, pressure within the actuator can back drive the piston. To prevent the backdriving of the piston there is a spring locking mechanism.
