    • An upper mounting structure for a wheel suspension includes a coil spring and a strut assembly each of which is adapted to be connected at its lower end with a wheel, while an upper end of the coil spring is coupled with a vehicle body through a spring insulator of high stiffness and an upper end of the strut assembly is coupled with the vehicle body through a strut mounting insulator of low stiffness. The structure further includes an additional insulator connecting between the upper ends of the coil spring and the strut assembly, which additional insulator has higher stiffness than the spring insulator within higher frequency range. Therefore, the strut assembly is capable of absorbing a surge vibration of the coil spring within the higher frequency range in spite of low stiffness of the strut mounting insulator.
    • 用于车轮悬挂的上部安装结构包括螺旋弹簧和支柱组件,每个支撑组件适于在其下端处与轮连接,而螺旋弹簧的上端通过弹簧绝缘体与车体联接 高刚度的上端和支柱组件的上端通过低刚度的支柱安装绝缘体与车体联接。 该结构还包括连接在螺旋弹簧的上端和支柱组件之间的另外的绝缘体,该额外的绝缘体在较高频率范围内具有比弹簧绝缘体更高的刚度。 因此,尽管支柱安装绝缘体的刚度低,但支柱组件能够在更高的频率范围内吸收螺旋弹簧的浪涌振动。

    • An active noise control system includes a plurality of vibration pickups for detecting of physical quantities of noise sources, such as vibrations of suspension members of a vehicle, and a plurality of microphones for detecting residual noises transmitted to observing positions. The output signals of the vibration pickups are added up by means of an adder to be input to a controller. The active noise control system also includes a plurality of delay circuits for applying delay times to the respective output signals of the vibration pickups so as to essentially equalize transmitting time of one of the output signals with that of the other output signals. The output signals of the microphones are input to the controller independently of each other. The controller outputs drive signals to a plurality of loudspeakers independent of each other to cause the loudspeakers to produce control sounds so that the control sounds interfere with the noises transmitted from the noise sources to decrease the noises transmitted to the observing positions.
    • 主动噪声控制系统包括多个用于检测噪声源的物理量的振动拾取器,例如车辆的悬挂构件的振动,以及用于检测传递到观察位置的残留噪声的多个麦克风。 振动拾取器的输出信号通过加法器相加以输入到控制器。 有源噪声控制系统还包括多个延迟电路,用于对振动拾取器的相应输出信号施加延迟时间,从而基本上使其中一个输出信号与其它输出信号的传输时间相等。 麦克风的输出信号彼此独立地输入到控制器。 控制器将驱动信号输出到彼此独立的多个扬声器,以使扬声器产生控制声音,使得控制声音干扰从噪声源发送的噪声,以减少发送到观察位置的噪声。
