摘要： A hydraulic control device for an anti-skid brake system for a vehicle, including a solenoid-operated directional control valve for communication of a pressure chamber in a hydraulic actuator, selectively with a hydraulic power source and a reservoir, and a solenoid-operated flow control valve disposed between the directional control valve and one of the pressure chamber, hydraulic power source and reservoir, the hydraulic control device being operated to effect rapid and slow rise and fall of a pressure in the hydraulic actuator, in response to a slip ratio of a wheel of the vehicle. The flow control valve comprises a flow restrictor which permits a restricted flow of a fluid through the valve even when its valving member is seated on a valve seat in which a valve hole is open. The flow restrictor is provided in one of various forms except an ordinary orifice with a small diameter. The flow restrictor may be a groove formed in an end face of a valving member opposite to the valve seat, a rough or ragged surface of the valve seat or valving member, or a porous structure formed on the valving member so as to contact the valve seat. Alternatively, the flow restrictor may be formed by a porous structure which fills a hole formed in parallel with the valve hole which is open in the valve seat.

摘要： A wheel slip controlling system according to the present invention comprises braking actuator operable by a driver of a car for braking rotation of wheels at least including driving wheels, slip detector for detecting a slipping condition of the wheels to output a slip signal indicative of the slipping condition, anti skid controller for receiving the slip signal and for controlling, in response to the slip signal received, the pressure to be imparted from the braking actuator with a self-contained pressure source to control braking slips of said wheels at least including the driving wheels and traction controller responsive to the slip signal during acceleration of the car for controlling the driving wheels with the self-contained pressure source for control acceleration slips at least of the driving wheels. Since the system makes use of the pressure of a hydraulic source of a conventional anti skid brake system and controls a braking system, quick responsiveness can be obtained without the necessity of extensive modification of the conventional anti skid brake system. When a driver carries out a braking operation to exhibit his own braking will, the braking operation will have a priority so that the slip control can be attained without deterioration of the treadling feeling of a brake pedal. If any other controlling technique such as priority of stabilized brake hydraulic pressure with a hysteresis is used in combination for selection of traction control, more stabilized acceleration slip control can be attained.

The wheel slip control system performs both of anti-skid control and traction control for a vehicle with a simple arrangement.

摘要： A three-port solenoid-operated valve has a fluid passage defined in a solenoid, a first port at an inlet end of the fluid passage, and second and third ports at an outlet end of the fluid passage. A cylindrical plunger is movably disposed in the fluid passage, and a slider is slidably supported in the plunger. A first-port valve body is normally urged by a first spring to be held against an end surface of the slider for opening the first port when the solenoid is de-energized. A third-port valve body is normally urged by a second spring for closing the third port when the solenoid is de-energized and is energized by a lower current. A pusher is fixedly mounted in the plunger for pushing the third-port valve body in a direction to open the third port in response to movement of the plunger when the solenoid is energized by a higher current. A third spring acts between the pusher and the opposite end surface of the slider for normally urging the pusher and the slider apart from each other. The second spring has a smallest spring force, the third spring has a largest spring force, and the first spring has an intermediate spring force between the spring forces of the second and third springs.

摘要： A hydraulic braking system having an auxiliary piston disposed between an input piston and a presser piston, so as to define a first power chamber between the auxiliary and presser pistons, and a second power chamber between the input and auxiliary pistons. The presser piston cooperates with a housing to define a pressure chamber connected to a first braking arrangement. The first power chamber is connected to a second braking arrangement and supplied with a power pressure from an external hydraulic source through a control valve and the second power chamber. The system includes a connecting mechanism connecting the auxiliary and presser pistons such that the two pistons are normally placed in a spaced-apart state but are abuttable on each other. The system also includes a valve device disposed in a passage formed through the auxiliary piston, so as to inhibit a fluid flow from the first power chamber to the second power chamber when the input and auxiliary pistons are advanced as a unit in abutting relation with each other, and permit fluid flows in both directions between the two power chambers when these pistons are placed in other conditions. The system is capable of activating the first and second braking arrangements by an operating force acting on the input piston through a manually operated mechanism, in the event of a power failure in the second power chamber or external hydraulic source.
