    • A hydraulic mount assembly is disclosed having a partition including a hydraulic damping decoupler between two hydraulic chambers. One chamber is formed by an elastomeric member and the other by a resilient diaphragm. During dynamic loading of the mount, fluid passes between the two chambers of the mount causing expansion and contraction of the diaphragm. A pneumatic bladder is positioned to exert external pressure against the diaphragm in order to change the damping characteristics of the mount. As the bladder is expanded, the diaphragm is stiffened and the fluid flow between the two chambers in the hydraulic mount is restricted. When the bladder is deflated, the pressure against the diaphragm is reduced or effectively removed thereby restoring full freedom of movement of the fluid in the hydraulic mount. By actively controlling the diaphragm expansion in this manner, the dynamic characteristics of the mount are varied. A control circuit with on-board transducers is provided to monitor vehicle operating and road response conditions and modulate the pressure to the bladder for maximum damping effect. The on-board transducers sense selected parameters to indicate unusual conditions for which modulation is required, such as rough engine operation, engine lugging, rough road conditions, sudden turning and/or rapid acceleration/deceleration.
    • 公开了一种液压安装组件,其具有包括两个液压室之间的液压阻尼解耦器的分隔件。 一个室由弹性构件形成,另一个由弹性隔膜形成。 在安装件的动态加载期间,流体在安装件的两个室之间通过,导致隔膜的膨胀和收缩。 定位气囊以对隔膜施加外部压力,以改变底座的阻尼特性。 当囊膨胀时,隔膜被加强并且液压座中两个腔室之间的流体流动受到限制。 当气囊放气时,减小或有效地去除隔膜的压力,从而恢复液压支架中的流体的完全自由运动。 通过以这种方式积极地控制膜片膨胀,安装座的动态特性是变化的。 提供具有车载换能器的控制电路以监测车辆操作和道路响应条件,并且调节膀胱的压力以获得最大阻尼效果。 车载换能器检测所选参数,以指示需要调制的异常情况,例如发动机运转粗糙,发动机悬挂,粗糙的道路状况,突然转动和/或快速加速/减速。
