摘要： A power steering apparatus for an automobile or other vehicle has a motor which rotates a steering shaft through an electromagnetic clutch and a worm gear reduction gear. When the clutch is engaged, the rotation of the motor causes the rotation of the steering shaft. When the clutch is disengaged, the steering shaft is not connected to either the reduction gear or the motor and can therefore be rotated manually with the same force as for a manual steering apparatus. The reduction gear and the electromagnetic clutch are coaxially disposed around the steering shaft.

摘要： A power steering apparatus for an automobile or other vehicle has a steering shaft constituted by an input section and an output section connected by a torsion bar. A mechanism for detecting when a driver is imparting torque to the steering wheel of the vehicle is constituted by a potentiometer having a resistive element and a wiper arm, one of which is mounted on the output section and the other of which is mounted on the torsion bar so that the wiper arm will rotate with respect to the resistive element and the resistance of the potentiometer will change when the torsion bar is rotated with respect to the output section. The potentiometer is electrically connected to a preamplifier mounted on the steering shaft, and the preamplifier is electrically connected to slip rings through which its output can be supplied to a stationary control unit. The electrical output of the potentiometer is independent of the speed of rotation of the steering wheel.

摘要： A motor-driven power steering apparatus and method for a vehicle are able to avoid frequent on-off operations of an electromagnetic clutch 14 as much as possible, which connects or disconnects a motor 13 with or from a steering system, thus improving the durability of the clutch 14 and suppressing the generation of undesirable noise and shocks upon connection and disconnection of the clutch 14. A clutch controller 191 controls a clutch current Ic supplied to the clutch 14 based on the vehicle speed V in such a manner that it sets the clutch current Ic to a first predetermined clutch current level I(V) so as to place the clutch into a substantially engaged state when the vehicle speed V is less than a first predetermined vehicle speed Vo, and to a second predetermined clutch current level Icr which is less than the first predetermined clutch current level I(V) so as to place the clutch into a partially engaged state when the vehicle speed V is equal to or greater than the first predetermined vehicle speed Vo. Preferably, the clutch current Ic is set to a third predetermined clutch current level Ico which is less than the second predetermined clutch current level Icr so as to substantially disengage said electromagnetic clutch when a steering torque T is equal to or greater than a predetermined value To when the vehicle speed is equal to or greater than the first predetermined value Vo.

摘要： An electromagnetic solenoid for use with a fluid control valve is disclosed in which a fixed iron core and a casing for housing a solenoid coil can be fabricated separately from each other without difficulty, and in which the configuration and the clearance between the fixed iron core and a movable iron core or the length of the extension of the fixed iron core from an end wall of the casing can be readily changed in accordance with the desired magnetic attraction characteristics thereof as required. The cylindrical casing has an end wall formed at its one end and is open at its other end, the open end being closed by an end cap member to form a yoke for a magnetic circuit. The fixed iron core is adapted to be separably connected with the end wall of the casing. An output rod is disposed in the casing with its one end extending outwardly through the end wall of the casing, the output rod slidably extending through the fixed iron core and being supported at its opposite ends by the end wall of the casing and the end cap member through a pair of slide bearings for axial sliding movement. A movable iron core is received in the hollow of the solenoid coil and fixedly mounted on the output rod in a face-to-face relation with the fixed iron core. The end wall of the casing has an insertion bore formed therein, and the fixed iron core has its one end firmly fitted into the insertion bore.
