。 Wheel brakes BF attached to wheels WF and WR suspended on the vehicle body 1 via suspension devices SF and SR
, BR and master cylinders MF, MR,
In the brake hydraulic control device for a vehicle, pressure reducing means 2F, 2R are interposed to reduce the output hydraulic pressure of the master cylinders MF, MR as the hydraulic pressure becomes equal to or higher than a set value, and apply the pressure to the wheel brakes BF, BR. The pressure reducing means 2F and 2R include a housing 33 and a piston 38 that is slidably fitted into the housing 33.
The housing 3 faces one end of the piston 38 while being connected to the wheel brakes BF and BR.
3 and the housing 3 while being connected to the master cylinders MF and MR sides.
an input chamber 41 formed within the piston 3;
A spring receiving member 44 is attached to the housing 33 to allow relative movement along the axial direction of the output chamber 42, and a piston 38 is mounted in the direction of contracting the volume of the output chamber 42.
until the pressure regulating spring 46 is compressed between the other end of the piston 38 and the spring receiving member 44 to bias the pressure, and the hydraulic pressure in the input chamber 41 reaches a hydraulic pressure equal to or higher than the set pressure determined by the pressure regulating spring 46. is configured to communicate the input chamber 41 with the output chamber 42 and to reduce the pressure in the input chamber 41 and guide it to the output chamber 42 when the oil pressure in the output chamber 42 exceeds the set pressure. and a valve mechanism V configured between the vehicle body 1 and the wheels WF.
, WR, and the housing 33 is connected to one of the vehicle body 1 and the other of the wheels WF, WR, and the housing 33 is connected to the vehicle body 1 and the other of the wheels WF, WR. A braking hydraulic control device for a vehicle, characterized in that a spring receiving member 44 is connected to drive the spring receiving member 44 in a direction that increases the spring load of the pressure regulating spring 46.
