摘要： It is an object of the invention to improve utility in a suspension apparatus for a vehicle having an electromagnetic actuator and a hydraulic damper. In the suspension apparatus, a hydraulic damper is disposed between an electromagnetic actuator and a wheel-holding portion, and a cover tube is provided for accommodating a seal provided between a piston rod and a housing of the hydraulic damper. In the suspension apparatus according to the present invention wherein the hydraulic damper is disposed between the wheel-holding portion and the electromagnetic actuator, it is possible to effectively mitigate not only transmission of vibrations to the vehicle body from the wheel via the electromagnetic actuator but also transmission of vibrations to the electromagnetic actuator. Further, owing to the presence of the cover tube, entry of dust and the like into the hydraulic damper through the seal can be effectively prevented.

摘要： It is an object of the invention to provide a suspension system configured to execute a control for avoiding a state in which an operation of an electric motor which is a power source of an electromagnetic actuator is kept halted at a certain operational position while the motor is generating a motor force. Where a target rotational position of the motor becomes equal to a specific operational position (e.g., a rotational position at which an electrifying current amount of one phase reaches a peak value), a control for shifting the target rotational position by δθ is executed. Where the rotational position of the motor is kept located at the certain position for a time period longer than a prescribed time, a control for changing the rotational position of the motor is executed. According to the present suspension system, it is possible to suppress imbalance in heat generation in the motor and to thereby reduce a load to be applied to the motor. Accordingly, a suspension system with high utility is realized.

摘要： It is an object of the invention to improve the utility of an electromagnetic absorber system which is disposed in a suspension system of a vehicle and which generates a damping force by a generation force of a motor. The electromagnetic absorber system 18 is equipped with high-speed-motion responding means, thereby obviating an insufficiency of the damping force and a deterioration of the controllability in a high-speed stroke motion. More specifically, a hydraulic absorber 64 is provided in combination with the electromagnetic absorber system such that the hydraulic absorber 64 operates in the high-speed motion in which an electromotive force of the motor 68 exceeds a power source voltage Further, two motors having mutually different T-N characteristics are provided, and the two motors are selectively operated depending upon a stroke speed. Further, a variable resistor is interposed between the motor and the power source, and a resistance value of the variable resistor is increased in the high-speed motion to realize a decrease in a time constant of the motor, etc. Moreover, to cope with a large extent of unevenness of a road surface, an active stroke motion is performed by a drive force of the motor, thereby preventing the high-speed motion from being performed.
