摘要： A cushioning material sheet to be interposed between a rack support and a press plug for applying an elastic force provided by a spring is formed such that at least its one end face is tapered. Slide-contact surfaces of the rack support and the press plug to be brought into contact with the two end faces of the cushioning material sheet are so formed as to move the cushioning material sheet in a direction perpendicular to a rack support direction, along which the thickness of the cushioning material sheet is decreased. A biasing member is provided to bias the cushioning material sheet in this direction of movement, thereby obtaining a proper meshed condition between a pinion and a rack.

摘要： An electric power steering apparatus includes a gear wheel on a driven side having a gear portion on one side surface thereof on a steering shaft and a pinion to be laterally meshed with a gear portion of the gear wheel on a shaft capable of transmitting a rotational driving force from an electric motor. The gear wheel and the pinion constitute a gear mechanism for transmitting a rotational force as a gear pair with non-parallel, non-intersecting axes. The gear wheel is axially supported on the steering shaft so as to be coupled in only a rotational direction and movable in an axial direction of the shaft. A biasing unit is provided on the other side of the gear wheel opposite to a portion of the pinion to be meshed with the gear portion and laterally urges the gear wheel toward the pinion.

摘要： A power steering valve system includes an input shaft and an output shaft which are aligned on a common axis, and also includes a control valve mechanism which is located offset from the axis in order to reduce the overall length of the valve system. The control valve mechanism includes a spool valve, a displacement of which from its neutral position controls the flow of a hydraulic oil from an oil pump to or from a power cylinder to assist in directing the steerable road wheels in a given direction. The input and output shafts are operatively associated with a motion translating mechanism which translates the magnitude of a relative torsion between the two shafts into a linear displacement. The motion translating mechanism is operatively associated with the spool valve to displace it from the neutral position in accordance with the magnitude of relative torsion between the two shafts.

摘要： A variable displacement pump has a cam ring, a rotor, a plurality of vanes, a pressure plate and a rear body. The cam ring is accommodated within a pump body. The rotor rotates within the cam ring. The plurality of vanes are inserted retractably into slits formed at regular intervals circumferentially in the rotor. The pressure plate and the rear body carry the cam ring and the rotor. A circular groove communicating to a back pressure inlet bore on a bottom portion of the slits is formed in a suction area on a face of the rear body on a side of the rotor. The groove is communicated via a communication passage to a passage between a power steering gear and a tank T to introduce a working oil after used in the power steering gear.

摘要： Disclosed herein is a hydraulic-pump controller that is capable of controlling absorbed pump torque in good balance against engine output at all times. In this hydraulic-pump controller, the discharge flow rates of the operating oil that are discharged from hydraulic pumps (9, 10) according to manipulation of manipulation units (12, 13) are predicted based on the discharge pressure of the hydraulic pumps (9, 10) that are driven by an engine (1), and based on the manipulation amount of the manipulation units (12, 13) that manipulate hydraulic actuators (27, 28), or a physical quantity correlating with the manipulation amount. Based on the predicted discharge flow rates and the discharge pressure, the absorbed torque of the hydraulic pumps is computed. Then, the predictive engine speed of the engine (11) is computed from the absorbed torque of the hydraulic pumps (9, 10) computed. Based on the deviation between the computed predictive engine speed and the actual engine speed of the engine (11), the regulators (12, 13) of the hydraulic pumps (9, 10) are controlled.

摘要： A cam ring 10 is slidably supported within a pump body 2, and a rotor 20 is rotatably disposed inside the cam ring. The cam ring is eccentric to a rotation shaft 22 of the rotor. The rotor carries a plurality of vanes 18 that can be advanced or retreated, in which a pump chamber 24 is formed in a space between the cam ring and the rotor. The cam ring is formed with the first and second fluid pressure chambers 14 and 16 on both sides thereof, and biased in a direction where the displacement of the pump chamber is at maximum by a spring 26. A control valve 28 is provided in which a differential pressure across a metering orifice is applied on both ends of a spool 32 and a spring 36 is disposed on the side of an end face where a downstream fluid pressure is applied. The fluid pressures of the fluid pressure chambers 14 and 16 are controlled by means of the control valve, whereby the cam ring is swung. A piston 58 that is moved in accordance with an increase in working pressure of a power steering apparatus is provided. This piston 58 exerts an axial thrust to an end face of the spool on the spring side.
