Abstract:
A brake apply system comprising:a wheel brake;a brake fluid reservoir;a braking actuator including a pressure generation mechanism hydraulically connected to the wheel brake through a first conduit and to the brake fluid reservoir and effective when activated to actuate the wheel brake with an actuator pressure;a pressure charging module including a bore carrying a pumping piston having a base piston surface and an augmentation piston surface and separating the bore into an input chamber adjacent the base piston surface and an output chamber adjacent the augmentation surface;a suspension damper hydraulically connected to the input chamber of the pressure charging module through a continuously open fluid communication circuit;an accumulator hydraulically connected to receive fluid flow from the output chamber of the pressure charging module and from the brake fluid reservoir, wherein the accumulator maintains brake fluid received from the brake fluid reservoir at an augmentation pressure charge generated by movement of the pumping piston as effected by operation of the damper; anda second conduit selectively connecting the accumulator to the wheel brake, wherein brake fluid at the augmentation pressure charge is selectively delivered to the wheel brake from the accumulator through the second conduit to augment brake fluid from the braking actuator.
