スキツドブレーキ装置。[Scope of Claim for Utility Model Registration] (1) An anti-skid brake system for a four-wheeled vehicle equipped with two systems of a first anti-skid control valve and a second anti-skid control valve, each provided between the first anti-skid control valve and the second anti-skid control valve, and a third anti-skid control valve provided between the second pressure chamber of the master cylinder and the front wheel brake device of the second system. and from the front wheel brake device or rear wheel brake device of the first system to the first system.
or a first hydraulic pump that pressurizes brake fluid discharged through a second anti-skid control valve and discharges it into a first supply pipe connecting the master cylinder and the first and second anti-skid control valves; A brake fluid discharged from the front wheel brake system of the second system through the third anti-skid control valve is pressurized and discharged to a second supply pipe connecting the master cylinder and the third anti-skid control valve. The differential piston device includes a piston body, and first and second master cylinder pressure chambers that receive pressure from the first and second pressure chambers of the master cylinder. , provided between first and second pressure receiving chambers connected to the first and second system rear wheel brake devices, respectively, the second master cylinder pressure chamber and the second pressure receiving chamber, and the second When controlling the anti-skid control valve, the first
A valve portion that opens and closes in response to movement of the piston body due to a pressure difference between the second pressure receiving chambers,
At least the first supply pipe is connected to the first and second supply pipes.
and a valve device capable of blocking liquid communication from the discharge side of the second hydraulic pump to the master cylinder side, and a throttle connecting the upstream side and the downstream side of the valve device, respectively, and the first and second master cylinder An anti-skid brake device characterized in that cylinder pressure chambers are connected to the upstream sides of the valve device in the first and second supply pipes, respectively. (2) The second anti-skid control valve is provided in a bypass conduit that bypasses the valve device and the throttle and connects the master cylinder and the first system rear wheel brake device. Anti skid brake device.
