摘要： Apparatus for controlling brake fluid pressure of a vehicle includes a hold valve provided in a first fluid passage so as to control fluid communication between a fluid pressure chamber in a master cylinder and a wheel cylinder, a decay valve provided in a second fluid passage so as to control fluid communication between a wheel cylinder and a reservoir; a supply valve provided in a third fluid passage so as to control the flow of brake fluid from a fluid pressure source to the fluid pressure chamber; an intake valve normally held in its closed position to shut off the third fluid passage, and a valve operating member mounted on the piston for movement therewith, the valve operating member being engageable with the intake valve when the stroke of movement of the piston reaches a predetermined value to thereby move the intake valve to its open position. With this construction, an anti-lock control for preventing the locking of the vehicle wheels can be effected. Further, an auxiliary piston is provided for moving the first-mentioned piston to applying a braking force when a slip of the vehicle wheels reaches a predetermined level, thereby achieving a traction control.

摘要： A solid box-shape structure is constituted by fitting a torque transmitting ring 23 to a guide hole 17 on a guide plate 11 to pivotably hold a lining member 13 and fixing the guide plate 11 to a torque receive plate 3. A braking torque is directly transmitted to the guide plate 11 by the torque transmitting ring 23 by pressing the lining member 13 to a disc rotor by a first link plate 7 and a second link plate 5 arranged on an inner side of the box-shape structure. A solid structure and alleviation of processing accuracy are made to be compatible with each other by constituting transmission of a press force and transmission of a torque by independent members in this way.

摘要： Counter braking force acting on a secondary shoe is input to one end portion of a control lever supported with an anchor pin vertically provided on a backing plate in such a manner that the control lever is capable of swinging. An inner end portion in the radial direction of the control lever engages with a strut for pressing a primary shoe against a brake drum. Pressing force A with which the strut is pressing the primary shoe against the brake drum is drastically reduced when braking force, that is, the counter braking force increases and slightly reduced when the braking force, that is, the counter braking force decreases, whereby an increase or a decrease in the braking force is made automatically controllable.

摘要： Within a wheel cylinder, a drive piston and a control piston, the base ends of which receives a hydraulic pressure from a master cylinder, are oppositely disposed while being axially aligned with each other. A primary shoe is pressed by the drive piston, and an anchor reaction force output from a secondary shoe is distributed to and loaded on an anchor portion and the control piston through a control lever. When the anchor reaction force reaches a predetermined value of force or larger, an anchor-reaction-force control link mechanism operates to move the primary shoe apart from a brake drum, thereby checking the increase of the anchor reaction force.
