    • The hydraulic mount assembly is disclosed having a partition forming two hydraulic chambers. A primary chamber is formed by an elastomeric member and a second chamber by a resilient diaphragm. The partition is formed by a pair of plates that define an intermediate cell between the chambers. The partition plates are both formed of conductive material and are connected by a conductor to ground potential. An intermediate plate of conducting material is mounted between the plates within the cell on spaced insulating pads. Preferably, the intermediate plate includes a peripheral skirt extending toward a cooperating continuous channel formed in one of the partition plates so as to form a dome with increased surface area and a tortuous pathway for the flow of fluid through the cell between the primary and secondary chambers. The plates are connected to a control circuit including a system controller with transducers that sense the operating conditions of the vehicle. The system controller is connected to a voltage source so that a voltage potential may be applied between the intermediate plate and the partition plates. This potential may be infinitely varied to modulate the viscosity of the electro-rheological fluid within the chambers of the mount. In this way the damping characteristics of the mount are adjusted to provide the desired balance between vibration isolation and engine and/or transmission movement control under any operating conditions.
    • 公开了具有形成两个液压室的隔板的液压安装组件。 主室由弹性体构件和第二腔室通过弹性隔膜形成。 隔板由一对板形成,这些板在室之间限定了中间室。 分隔板均由导电材料形成,并通过导体与地电位连接。 导电材料的中间板安装在电池内的间隔绝缘垫的板之间。 优选地,中间板包括朝向形成在一个隔板中的协作连续通道延伸的周边裙部,以便形成具有增加的表面面积的圆顶和用于使流体流过初级和次级室之间的电池的曲折路径 。 这些板连接到包括感测车辆的操作条件的换能器的系统控制器的控制电路。 系统控制器连接到电压源,使得可以在中间板和分隔板之间施加电压电位。 该电势可以无级变化,以调节安装座腔室内电流变流体的粘度。 以这种方式,调节安装座的阻尼特性以在任何操作条件下在隔振和发动机和/或变速器运动控制之间提供期望的平衡。
