Wheel brake control device

Abstract

Abstract PURPOSE:To facilitate a traction control by providing a selector valve, which can be selected to the first mode directly connecting a master cylinder to a wheel cylinder and to the second mode connecting the cylinders through a pump, to be interposed between the master cylinder and an antiskid circuit. CONSTITUTION:A traction control selector valve 14 serving as the 3-port 2-position valve connects its input port 14a to a master cylinder 12 through an oil line L11, and this input port 14a communicates with one output port 14b, when a solenoid 14A is turned off, while being selected to another output port 14c when the solenoid 14A is turned on. The output port 14b connects to a delivery port 16a of a pump 16 through an oil line L12 while to each input port 17a, 18a of each right and left wheel antiskid selector valve 17, 18 through oil lines L13 and L14. While the other output port 14c is connected to a reservoir 19 and a suction port 16b of the pump 16 through an oil line 15.
