摘要： A vehicle braking system includes: a hydraulic booster which applies output hydraulic pressure of a hydraulic power source to a boosted hydraulic pressure chamber after regulating the output hydraulic pressure as a control piston operates to balance reaction force generated by hydraulic pressure of the boosted hydraulic pressure chamber with brake operating input; and a brake stroke simulator installed between the brake operating member and the control piston in order for a driver to feel operating strokes of the brake operating member. The brake stroke simulator has: an input member axially slidably housed in the control piston of a cylindrical shape and linked to the brake operating member; and an elastic body interposed between the input member and the control piston. The elastic body is formed into a tubular shape so as to come into resilient contact with an inner circumference of the control piston by expanding its diameter under the action of axial compressive force generated by forward movement of the input member. Consequently, the brake stroke simulator allows large hysteresis width in relationship between brake operating stroke and operating load.

摘要： A simulator piston is slidably fitted in a control piston to form a stroke liquid chamber between itself and an end wall of a control piston. A port which is closed at a forward limit of the control piston with respect to a backup piston is provided in the end wall of the control piston. A first reaction piston which constantly abuts against the end wall of the control piston and a second reaction piston which abuts against the end wall of the control piston when the control piston advances toward the backup piston through a predetermined travel distance or more, are relatively slidably mounted on the backup piston so that hydraulic pressure of the boosted hydraulic pressure chamber acts on their front ends. Thus, it is possible to curb increase in a stroke and reaction of a brake operating member which would be invalidated by a brake stroke simulator when a hydraulic power source fails, and avoid insufficient strokes of the brake operating member even if spikes are inputted.

摘要： A vehicle braking system includes: a hydraulic booster which applies output hydraulic pressure of a hydraulic power source to a boosted hydraulic pressure chamber after regulating the output hydraulic pressure as a control piston operates to balance reaction force generated by hydraulic pressure of the boosted hydraulic pressure chamber with brake operating input, the boosted hydraulic pressure chamber facing the rear face of a master piston of a master cylinder; and a brake stroke simulator installed between a brake operating member and the control piston. The hydraulic booster includes a backup piston which is slidably housed in a casing with its front face turned to the boosted hydraulic pressure chamber and which can directly push the master piston in response to operation of the brake operating member when the hydraulic pressure of the boosted hydraulic pressure chamber decreases. The control piston and the brake stroke simulator are contained in the backup piston. Thus, it is possible to improve the efficiency in assembling the hydraulic booster and brake stroke simulator to the casing of the master cylinder.

摘要： A fluid pressure booster includes: a control piston in which brake operation input acts in an advancing direction, and reaction based on fluid pressure of a booster fluid pressure generation chamber that generates fluid pressure for actuating a master piston acts in a retracting direction; a pressure increasing valve provided between the booster fluid pressure generation chamber and a fluid pressure generation source so as to open at the time of advance of the control piston and close at the time of retraction of the control piston; and a pressure reducing valve provided between a release chamber and the booster fluid pressure generation chamber so as to close at the time of the advance of the control piston and open at the time of the retraction of the control piston. The pressure increasing valve includes first valve means and second valve means that sequentially open according to an increase in the brake operation input, and a seal diameter of the second valve means is larger than that of the first valve means. Thus, it is possible to enhance initial response of the pressure increasing valve, and also enhance response of the pressure increasing valve when a brake operation member is strongly operated.

摘要： A hydraulic controller includes: a pair of liquid chambers; and an on-off valve capable of opening and closing a flow channel on the side of the liquid chamber with a higher hydraulic pressure out of the pair of liquid chambers. The flow channel can provide communication between the pair of liquid chambers. A baffling device is provided in the liquid chamber with a lower hydraulic pressure, to baffle hydraulic fluid flowing from the liquid chamber with the higher hydraulic pressure. Thus, it is possible to reduce operating noise resulting from operation of the on-off valves.
