    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： 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： A method of and a system for controlling a hydraulic shock absorber of an automobile are provided. In the shock absorber, a flow of damping fluid induces a load on an actuator of the shock absorber during bouncing and rebouncing of the shock absorber, and the actuator is actuated in response to an output signal of a control unit. In order for the actuator to counteract the load applied thereto, the output signal is modified in response to the load. According to the embodiment, the load is determined by a table look-up operation based on an input load detected by a load sensor mounted to the automobile.
