    • A mount assembly is provided for mounting a component, such as an engine, to a vehicle for active control of vibration. The assembly includes first and second mounting members and, an intermediate insert with first and second elastomeric systems connecting said first and second mounting members with the intermediate insert in between. An actuator in parallel with said first elastomeric system provides vertical force to said first elastomeric system to provide a relatively soft vertical rate. A controller operates the actuator in response to sensed vibration so that the vertical force tends to avoid or cancel it. A relatively high fore/aft and lateral dynamic rate of the first system protects the actuator. The second elastomeric system connects the second mounting member with the intermediate insert and exhibits a relatively high vertical rate and a relatively soft fore/aft and lateral rate. One or more sensors feeds data to a controller that analyzes the vibrations to determine the harmonics thereof. The controller then constructs one or more output waveforms and feeds them to the actuator so that a force is applied across the first elastomeric system between the first mounting member and the intermediate insert, thereby tending to produce the relatively soft vertical rate for component isolation and noise suppression.
    • 提供了用于将诸如发动机的部件安装到车辆上用于主动控制振动的安装组件。 该组件包括第一和第二安装构件,以及具有第一和第二弹性体系统的中间插入件,其将所述第一和第二安装构件与中间插入件连接在其间。 与所述第一弹性体系统平行的致动器向所述第一弹性体系统提供垂直的力以提供相对较软的垂直速率。 控制器响应于感测到的振动来操作致动器,使得垂直力倾向于避免或取消它。 第一系统的相对较高的前/后和横向动态速率保护致动器。 第二弹性体系统将第二安装构件与中间插入件连接,并且呈现相对高的垂直速率和相对较软的前/后和横向速率。 一个或多个传感器将数据馈送到分析振动的控制器以确定其谐波。 然后,控制器构造一个或多个输出波形并将其馈送到致动器,使得在第一安装构件和中间插入件之间跨越第一弹性体系统施加力,从而趋向于产生用于部件隔离和噪声的相对柔软的垂直速率 抑制。

    • A hydraulic mount assembly is disclosed having a partition forming two hydraulic chambers and including a damping decoupler. A primary chamber is formed by an elastomeric member and a secondary chamber by a resilient diaphragm. During dynamic loading of the mount, fluid passes through an orifice between the two chambers of the mount causing expansion and contraction of the diaphragm. An expandable, pneumatic bladder is mounted within the primary chamber. A tube provides fluid communication between the bladder and the atmosphere. When a valve in this tube is open, air freely enters and escapes the bladder in symphony with the vibrating mount. Alternatively, the valve may be closed and a positive pressure provided to the bladder from a variable pressure fluid supply. By actively controlling bladder expansion and contraction in this manner, the dynamic rate of the mount assembly may be selectively reduced at relatively high vibration frequencies; that is, those over 20 Hz. Damping may also be reduced to provide a relatively soft mount for engine isolation. Further, by evacuating the bladder, a relatively hard mount may be provided exhibiting relatively high damping and high rate for better engine control. A control circuit with on-board transducers is also provided to monitor vehicle operating and road conditions and modulate the pressure in the bladder for maximum operating efficiency.

    • A hydraulic mount assembly is disclosed having a partition forming two hydraulic chambers and including a damping decoupler. A primary chamber is formed by an elastomeric member and a secondary chamber by a resilient diaphragm. During dynamic loading of the mount, fluid passes through an orifice between the two chambers of the mount causing expansion and contraction of the diaphragm. An expandable, pneumatic bellows is mounted within the primary chamber. A vent tube provides controlled fluid communication between the bellows and the atmosphere to provide a relatively soft mount for engine isolation. Air entry into the bellows is induced by the built-in spring memory of the bellows causing expansion. Air may be removed or partially removed from the bellows by an external vacuum source, causing a negative pressure and contraction. By controlling bellows expansion and contraction in this manner, the dynamic rate of the mount assembly may be selectively reduced at higher vibration frequencies; that is, those over 20 Hz. An assist spring may be provided in the bellows. Further, by evacuating the bellows, a relatively hard mount with standard operating parameters may be provided; i.e. a mount having relatively high damping and high rate for better control under extreme driving conditions. A control circuit with on-board transducers is provided to monitor vehicle operating and road conditions and modulate the pressure by controlling venting of the bellows and the vacuum in the bellows for maximum operating efficiency.

    • A hydraulic mount assembly includes a pair of mounting members connected together to form a hollow elastomeric body closed by a resilient diaphragm so as to form a cavity for a damping liquid. A partition divides the cavity into a primary chamber formed between the partition and the hollow body and a secondary chamber formed between the partition and the diaphragm. The partition also includes a primary orifice track, a secondary orifice track and a decoupler passage providing fluid communication between the chambers. A first decoupler is mounted for limited reciprocating movement in the decoupler passage. A spring biases the first decoupler to a seated position sealing the passage. A second decoupler is mounted for limited reciprocating movement in the secondary orifice track. The primary orifice track establishes a first resonance frequency for the damping liquid. Similarly, the secondary orifice track establishes second, higher resonance frequency. Further, the force provided by the coil spring against the first decoupler is overcome by fluid pressure at a third resonance frequency higher than that of the second resonance frequency. Together these structures function to provide a rate dip and improved relatively high frequency tuning in a fully passive mount assembly.
