摘要: A linear dual channel hydraulic control unit for a motor vehicle, having a motor section with an output shaft having a first output shaft end and an opposing second output shaft end. A rotationally adjustable wobble plate having an apex portion is fixed onto either end of the output shaft. A hydraulic block is mated onto either end of the motor section. Each hydraulic block includes an inlet for fluid communication with a braking fluid source and an outlet for fluid communication with a braking system brake, a pump cavity housing a pumping assembly and having an opening disposed on a first end, and first and second valve cavities housing first and second fluid control valves. Mated to each hydraulic block is a control sections providing first and second solenoid coils receiving portions of the first and second fluid control valves. The pumping assembly is reciprocally driven by the rotatable piston bearing surface along an axis radially disposed from and otherwise parallel to the axis of rotation of the rotatable piston bearing surface. Each of the wobble plates includes an apex that can be rotationally offset relative to the other about the axis of rotation ‘A’ to control the timing of the output cycle of the pumping assemblies; thereby reducing or eliminating the natural harmonic vibrations of the pumping assemblies and/or minimizing the current draw of the motor.
