分离件74包括移动构件90，该移动构件90具有大致圆形形状，设置在中心轴线A上，位于泵送腔室30中。移动构件90从中心轴线A径向地向外延伸到支撑构件上端78。分离件74附接到支撑构件上端78，将泵送腔室30与容纳腔室32、34分隔开。由弹性材料制成的隔膜92设置在容纳腔室32、34中。隔膜92在下部开口端38与套环42的远端44之间绕中心轴线A环形地延伸。隔膜92被夹在下部24与分隔构件72之间以及支撑构件下凸缘86与套环42的远端44之间，将容纳腔室分成流体腔室32和补偿腔室34。流体腔室32在隔膜92与分隔构件72之间延伸。补偿腔室34在下部24与隔膜92之间延伸。
分隔构件72包括上间隔件94，该上间隔件94由金属制成并具有大致环形形状，设置在泵送腔室30中，在轴向上与上部26相邻并位于上部26下方，并且与柔性体凸缘70接合，以将柔性体凸缘70夹在上部26与上间隔件94之间。上间隔件94包括至少一个突出部96，该至少一个突出部96从上间隔件94向外延伸以接合柔性体凸缘70，以将柔性体凸缘70固定在上部26与上间隔件94之间。上间隔件94限定了至少一个上间隔件凹槽98，该至少一个上间隔件凹槽98设置成与至少一个突出部96相反并且与至少一个突出部96轴向地间隔开，沿着上间隔件94绕中心轴线A环形地延伸。由弹性材料制成的密封件100设置在上间隔件凹槽98中并且绕中心轴线A环形地延伸。
分隔构件72包括电磁支撑环102，该电磁支撑环102具有大致环形形状，设置在所述流体腔室32中，位于上间隔件94与下部24之间。电磁支撑环102绕中心轴线A环形地延伸以将隔膜92夹在电磁支撑环102与下部24之间。电磁支撑环102还将密封件100夹在电磁支撑环102与上间隔件94之间。电磁支撑环102限定了凹口104、至少一个通道106和电磁凹槽108。凹口104具有大致柱形形状，沿着中心轴线A延伸以容纳分离件74。与凹口104和分离件74径向地间隔开的至少一个通道106穿过电磁支撑环102平行于中心轴线A延伸，以允许泵送腔室30与流体腔室32之间的流体连通。设置成与壁28相邻并与至少一个通道106径向地间隔开的电磁凹槽108绕中心轴线A环形地延伸。电磁场发生器110设置在电磁凹槽108中。电磁场发生器110包括线圈架112，该线圈架112具有大致线轴形状，设置在电磁凹槽108中并绕中心轴线A环形地延伸。至少一个线圈114绕线圈架112环形地缠绕并且电连接到电源116，用于选择性地产生磁通量。
如图3中最佳所示，移动构件90是固定到分离件74的非弹性聚合物片，以提供附加的阻尼力。具有大致圆形形状的移动构件90是模切聚合物片并且具有绕中心轴线A延伸的外周边118。在移动构件90是非弹性聚合物的情况下，它还使移动构件90与磁流变流体之间的化学反应最小化，从而延长了分离件74和液压悬置装置20的工作寿命。
更具体地，研究已经表明，包含在磁流变流体中的乙氧基化胺、丙二醇和其他添加剂倾向于与液压悬置装置20的弹性材料起反应。这种化学反应在液压悬置装置20中产生气体，所述气体引起压力升高，从而抑制液压悬置装置20的全功能性能。另外，反应还在磁流变流体组合物中形成二聚体和三聚体，从而破坏在磁流变流体组合物中形成的触变网络并且使磁响应颗粒从磁流变流体组合物中沉淀下来，从而减少了磁流变流体组合物的寿命。在移动构件90是非弹性聚合物的情况下，本发明使移动构件90与磁流变流体之间的化学反应最小化，以防止磁响应颗粒从磁流变流体中沉淀下来并且允许分离件74和液压悬置装置20在更长的时间段期间工作。
具有大致圆形形状的盖120设置在泵送腔室30中，与分离件74间隔开，以将移动构件90固定在盖120与分离件74之间。盖120包括下板122，该下板122具有大致圆形形状，设置成与移动构件90轴向地间隔开。突起124从下板122朝向分离件74向外延伸以接合移动构件90并且将移动构件90固定到分离件74。应该理解的是，突起124可绕中心轴线A环形地延伸以将移动构件90固定到分离件74。下板122限定了至少一个孔口126，该至少一个孔口126延伸穿过盖120以允许磁流变流体流过盖120。应该理解的是，至少一个孔口126可包括彼此径向地且周向地间隔开的多个孔口126，以允许磁流变流体流过盖120。
盖120包括肋部128，该肋部128在与突起124相反的方向上平行于中心轴线A从下板122向外环形地延伸。肋部128具有内表面130和外表面132。肋部118的内表面120面向中心轴线A。肋部128的外表面132设置在与内表面130相反的侧上并面向壁28。盖120限定了袋部134，该袋部134设置成与泵送腔室30流体连通。袋部134在肋部128的内表面130与下板122之间延伸。外表面132在移动构件90的外周边118附近被倒角，限定了绕中心轴线A环形地延伸的导管136。由弹性材料制成的O形环138设置在导管136中并且绕中心轴线A环形地延伸，与外表面132和移动构件90的外周边118密封接合。分离件包括设置在凹部88中的压缩板140，该压缩板1408在与盖120相反的侧与移动构件90相邻并与移动构件90间隔开，以限制移动构件90的移动。换句话说，分离件中的唯一橡胶部件是O形环138，该O形环138在盖120与移动构件90之间提供了密封功能。另外，应该理解的是，由非弹性聚合物制成的移动构件90具有比橡胶大的刚度，这提供了使用包括金属插入件的弹性移动构件的低成本另选方案，从而限制了对金属插入件的需要。此外，O形环138和盖120的组合允许移动构件90被适当地固定到分离件74并且抵抗移动构件90在正压力下挤压到压缩板140中和在真空下挤压到盖120中。
图4和图5提供了本发明的分离件74的另选实施例。如图4和图5中所例示，应变计传感器142设置在流体腔室32中并附接到移动构件90，用于根据移动构件90的移动测量移动构件90上的载荷。引线144电连接到应变计传感器142并延伸穿过压缩板140。引线144还电连接到用于接收并分析从应变计传感器142接收到的信号的处理器。换句话说，由应变计传感器142产生的信号允许用户测量分离件74的移动构件90的频率成分。压缩板140限定了通路146，该通路146延伸穿过压缩板140，用于接收引线144以允许引线延伸穿过分离件74。应该理解的是，代替引线144，应变计传感器142可包括无线模块，该无线模块可将应变计传感器142的信号无线传输给用户。
在工作中，当液压悬置设备90接收到激励移动(例如振动移动)时，柔性体56变形，从而引起泵送腔室30、流体腔室32和补偿腔室34的体积的变化。结果，移动构件90响应于体积变化而在泵送腔室30中弯曲(flex)。随着移动构件90在泵送腔室30中弯曲，移动构件90响应于激励移动而在泵送腔室30中提供附加的阻尼力。当移动构件90正在泵送腔室30中弯曲时，应变计传感器142记录和监视移动构件90并且根据移动构件90的移动来测量移动构件90的载荷。由应变计传感器142产生的信号经由引线144被传送给用户，这允许用户测量分离件74的移动构件90的频率成分。
显然，根据上述教导，对本发明的许多修改和变型是可能的，并且这些修改和变型可以以与具体描述不同的方式来实施，同时在所附权利要求的范围内。这些在先陈述应该被解释为涵盖本发明新颖性实践其实用性的任何组合。
本申请要求于2018年9月10日提交的序列号为62/729,344的美国临时专利申请的权益，其全部公开通过引用在此并入本文。
