摘要

CAM MODULATOR FOR ANTI-LOCK BRAKING SYSTEM APPARATUS AND METHOD An anti-lock braking system system (ABS) pressure modulator is provided. The modulator includes a frame with a central bore fluidly exposed to a solenoid valve and to a vehicle wheel cylinder. A piston is slidably mounted within the central bore having a contact surface and a first predetermined position within the bore. A power means is actuated by a controller. A cam, moved by the power means, has a ramp surface in contact with the piston contact surface. The position of the piston within the wheel cylinder is determined by the position of the cam.
