Abstract

PURPOSE:To simplify the hydraulic circuit by integrating an anti-lock control device and a traction control device in a body centering round a valve device. CONSTITUTION:A valve device 1 is constructed so that in the steady state, input and output ports 3, 4 are communicated with each other to apply liquid pressure of a master cylinder M/C to a wheel cylinder W/C. When there is a fear of lock in a driving wheel W1, the brake fluid pressure of the cylinder W/C is absorbed by the movement of a piston 8. Anti-lock control is conducted by opening and closing a decay valve 51 and a build valve 56 to repeatedly apply and reduce the liquid pressure of an accumulator 54 to a back pressure chamber 24. Further, when an accelerating slip is caused in the driving wheel W, liquid pressure in an output chamber 23 is applied to the cylinder W/C by the movement of the piston 8 to brake a slip. This traction control is conducted by opening and closing the decay valve 51 and the build valve 56 to repeatedly apply and reduce the liquid pressure of the accumulator 54 to the back pressure chamber 24. Thus, the hydraulic control circuit can be simplified.
