    摘要: A worm wheel is mounted to a steered shaft to rotate therewith. A brushless electric motor has an output shaft and is able to generate a power for assisting turning of the steered shaft when energized. A worm gear is coaxially connected to the output shaft of the motor to constitute a combined shaft structure. The worm gear is meshed with the worm wheel. Two bearings bear axially opposite end portions of the combined shaft structure respectively.

    摘要: An elastically deflectable sensor body has an inner peripheral portion engaging with a first portion of a radially extending wall of a lid closing one end of a cylinder of a shock absorber for movement therewith and an outer peripheral portion engaging with a second portion of the radially extending wall. A first pair of diametrically opposed strain gages and a second pair of diametrically opposed strain gages are placed on the sensor body. A first Wheatstone bridge circuit has the two diametrically opposed strain gages of the first pair in series. A second Wheatstone bridge circuit has the two diametrically opposed strain gages of the second pair in parallel.

    摘要: A variable damping characteristics shock absorber includes a piezoelectric unit which serves as a sensor for detecting piston stroke and an actuator for adjusting stiffness of a flow restriction valve and thus for adjusting the damping characteristics of the shock absorber. The shock absorber includes a pair of flow restriction valves, in which one of valve is active in response to a piston bounding stroke for generating damping force by restricting the fluid flow and the other is active in response to a piston rebounding stroke for generating a damping force by restricting fluid flow. The piezoelectric unit is disposed between two valves in such a manner that it may monitor piston strokes both in the bounding and rebounding stroke directions and adjust stiffness of both of the flow restriction valves.

    摘要: In an apparatus for controlling a variable damping coefficient for at least one vehicular shock absorber, the shock absorber being interposed between a vehicle body and a tire wheel, an adjuster of the shock absorber which is so constructed as to change its position so as to provide an optimum damping coefficient for the shock absorber in response to a drive by means of an actuator (pulse motor), vehicle behavior detector which is so constructed as to detect a vehicle behavior, a damping coefficient control portion to derive an optimum damping coefficient according to the vehicular behavior, and a drive/control portion to form a drive/control signal to actuate the actuator, the drive/control portion is separated from the damping coefficient control portion and is integrally incorporated into the actuator. Furthermore, a fail safe circuit is integrally incorporated into the actuator, which is so constructed as to provide a predetermined fail safe drive for the actuator upon receipt of a signal indicating an occurrence of abnormality in either the damping coefficient control portion or drive/control portion from the damping coefficient control side.
