Brake hydraulic pressure controller

Abstract

Abstract PURPOSE:To eliminate the slip on start by installing a motor which revolves in advance by the detection of slip and revolves reversely by the release of detection, valve body which is moved in reciprocation by the motor, and an oil chamber whose capacity reduces when the communication to a master cylinder is cut off by the advancing movement of the valve body. CONSTITUTION:The top edge of a valve body 3 installed in slidable ways into a cylinder body 2 is set close to the output hydraulic pressure 5 which communicates to the wheel cylinder W/C of a driving wheel brake device. Further, the rear edge of the valve body 3 is interlocked with the screw shaft 6a of a normal/reverse revolving motor 6 through a screw hole 3c. Then, the normal/reverse revolving motor 6 is revolved normally by the detection of the slip on the start of a car by an electronic controller 8. Then, the valve body 3 advances, and the communication between a master cylinder M/C and the output oil chamber 5 is cut off, and the capacity in the output oil chamber 5 reduced, and the hydraulic pressure increases by that portion and transmitted to the wheel cylinder W/C, and thus slip is prevented.
