摘要： The hydraulic power steering system comprises a rotary valve unit actuated according to a twisting angle provided in a torsion bar connected between an input shaft and a pinion, and a conversion mechanism which can change the condition of the rotary valve unit for a given twisting angle of the torsion bar. A variable ratio lever mechanism may be used for this purpose. Thus, a torsion bar having a suitable rigidity can be used without causing any insufficiency in the assisting torque because the responsiveness of the steering system can be freely varied by changing the setting of the conversion mechanism. For instance, it is possible to provide a sufficient assist torque at low speed and a controlled responsiveness at high speed.

摘要： A power steering system is disclosed which automatically corrects unexpected variations in the path of a vehicle without requiring a driver to make corrections. A rotary valve in the power steering system includes an inner sleeve connected to a steering wheel, an outer sleeve connected to a pinion shaft meshed with a rack bar, and a torsion bar coupled to the inner sleeve and the pinion shaft. The rotary valve switches oil passages communicating with a power cylinder by means of relative rotation between the inner sleeve and the outer sleeve to thereby assist in steering. The outer sleeve and the pinion shaft are connected to each other for slight relative rotation through an elastomer or resilient connecting member. If an unexpected variation in path is produced in the vehicle, the outer sleeve is rotated by the operation of a torque motor which causes the operation of the rotary valve, thereby moving the power cylinder whereby a steering force is produced for correcting the variation in path.

摘要： An improved power steering device which has a pinion shaft connected with a steering wheel, a rack rod which is connected with steerable wheels and whose rack is in mesh with the pinion of the pinion shaft in the gear box, a power cylinder for hydraulically actuating the rack rod, and a changeover valve for selectively connecting the first and second hydraulic chambers of the power cylinder with the hydraulic pressure source and the oil reservoir. The pinion shaft is rotatably supported in the oscillating cage which is rotatably mounted on the gear box in a manner such that the axis of the oscillating cage is offset a certain distance from the axis of the pinion shaft, whereby the oscillating cage rotates about its axis when the steering torque is applied to the pinion shaft. The oscillating cage is connected with the changeover valve so that the latter is actuated by the rotary movement of the oscillating cage. With this construction, the changeover valve can be made to respond accurately to the steering torque and at the same time it is possible to reduce the size and simplify the structure of the device.

摘要： A steering mechanism for vehicle equipped with a power steering system, the steering mechanism including a resilient element, such as a torsion bar, which is interposed in a path of torque transmission between a steering wheel and a power steering unit which provides an increased steering reactive force in proportion to vehicle speed. The steering mechanism includes a damper arrangement disposed between two relatively rotatable members which are operably associated with each other through the resilient element. The damper arrangement attenuates torsional vibrations of a first one of the relatively rotatable members disposed on the side of the steering wheel, such vibrations being caused by the interposed resilient element and the moment of inertia of the steering wheel.

摘要： A power steering apparatus including a reaction control valve operable to be opened by a force proportional to a speed of a vehicle, and to be closed under a pressure in a reaction chamber. The pressure of a source of hydraulic pressure or a pressure proportional to the pressure of the hydraulic pressure source is applied so as to open the reaction control valve even when the vehicle speed exceeds a predetermined value. Thus, a steering reactive force, which would otherwise be limited at the predetermined speed of the vehicle, is controlled so as to be proportional at a proper ratio to a resistance from a road as it increases, thereby assuring more accurate steering of a vehicle.

摘要： In the joining structure of the solid electrolytic element, terminals connected to the heating element and the electrodes are attached through metallic oxide layers onto the solid electrolytic layer. The thermal conductivity coefficient of the metallic oxide layers is larger than that of the solid electrolytic layer. The thermal expansion coefficient of the metallic oxide layers is the same as or smaller than that of the solid electrolytic layer. Consequently, when the lead wires are soldered to the terminals, heat is quickly conducted to the terminals, enhancing the fluidity and the solderability of the soldering material. Since excess heating is not required for soldering, the solid electrolytic layer is prevented from deteriorating due to heat. Since a low-melting solder is not used, the joining structure has high heat resistance. Moreover, during soldering, the metallic oxide layers do not detach from the solid electrolytic layer due to heat.
