具体实施方式
本公开涉及一种根据道路状况和车辆动力学持续调节阻尼水平的阻尼系统。参考图1，示出了具有悬架系统12和车身14的车辆10。悬架系统12包括阻尼器20和螺旋弹簧22。阻尼器20是半主动的，其阻尼水平由电子控制单元(ECU)25控制。ECU25从车辆的不同位置处的传感器(未示出)接收信息(加速度、位移、转向、制动、速度)以对每个阻尼器进行独立调整。
参考图2和图3，示例性公开提供了一种持续可变阻尼器20，其包括具有第一端和第二端的长形外管24。外管24具有同心地包括在其中的内管26。杆32包括在内管26内，该杆32包括在第一杆端部31处的活塞30。杆32包括第二端部34，第二端部34通过杆引导组件36延伸到外管24的外部。如图所示，活塞30和内管26限定回弹工作室38和压缩工作室40。回弹工作室38和压缩工作室40包括流体、优选地适合与阻尼器一起使用的液压油。
阻尼器20包括主动回弹阀42，其通过流体室18和远端内管孔94与回弹工作室38流体连通。主动回弹阀42具有可由ECU25控制的可变的流动阻力。阻尼器20还包括主动压缩阀44，其通过近端内管孔96与压缩工作室40流体连通。主动压缩阀44具有可由ECU25控制的可变的流动阻力。如图所示，主动回弹阀42和主动压缩阀44位于外管24的外部并且被间隙46分隔开。吸入组件50设置在流体室18内并且可以定位在间隙46处。吸入组件50通过外管吸入孔52与主动回弹阀42和主动压缩阀44选择性地流体连通，从而使得吸入组件50在回弹和压缩冲程期间控制流体流动。
参考图5，吸入组件50可包括回弹环54和压缩环56。回弹环54包括至少一个回弹孔55，并且优选地包括两个回弹孔。回弹孔55被可弯曲的回弹盘58阻挡，压缩孔57被可弯曲的压缩盘60阻挡。如图5所示，还可以设置回弹支点间隔件62和压缩支点间隔件64。如图5所示，该组件可以通过紧固件69保持在一起。可弯曲的回弹盘58和可弯曲的压缩盘60被偏置以分别关闭回弹孔55和压缩孔57。如图2所示，在回弹冲程期间，流体从回弹工作室38流出远端内管孔94，并且通过流体室18流到主动回弹阀42，随后通过吸入组件50进入压缩工作室40。如图3所示，在压缩冲程期间，流体从压缩工作室40流出近端内管孔96，并且通过流体室18流到主动压缩阀44，随后通过吸入组件50进入回弹工作室38。
有利地，如(沿图2的剖面线4-4截取的)图4所示，吸入组件50呈环形并且位于流体室18中，这允许活塞30延伸超过主动回弹阀42和主动压缩阀44，从而，与诸如第No.2020/0208705A1号美国专利申请文献中示出的传统阻尼器相比减小了阻尼器20的固定长度。本公开的吸入组件50可用于如图2和图3所示的具有蓄能器的阻尼器、或如图7所示的更传统的双管阻尼器。
图2和图3中所示的阻尼器20包括蓄能器80。蓄能器80通过蓄能器孔82与主动回弹阀42和主动压缩阀44流体连通。蓄能器包括低压室84，低压室80与压缩工作室40被端壁86分隔开。蓄能器80还包括柔性膜88和气室90。蓄能器80可以接收或排出本领域已知的流体。
主动回弹阀42通过外管24中的主动回弹阀孔92与流体室18流体连通，并且通过内管26中的远端内管孔94与回弹工作室38流体连通。远端内管孔94与回弹工作室38流体连通。在回弹冲程期间，流体从回弹工作室38通过流体室18流出远端内管孔94，并且通过外管24中的主动回弹阀孔92进入主动回弹阀42，随后通过吸入组件50进入压缩工作室40并且通过近端内管孔96进入压缩工作室40。主动压缩阀44通过外管主动压缩阀孔93和近端内管孔96与流体室18流体连通。在压缩冲程期间，流体从压缩工作室40流出近端内管孔96，通过外管24中的主动压缩阀孔93进入主动压缩阀44，通过吸入组件50、通过流体室18并通过远端内管孔94进入回弹工作室38。
参考图4-图6D，更详细地示出了吸入组件50。如上所述，吸入组件50包括回弹环54和压缩环56。回弹环54和压缩环56可以具有相同的构造。回弹环54和压缩环56均可以分别包括一对孔55和57，每个孔的形状可以是弓形的，如图6A所示。回弹环54上的孔称为回弹孔，而压缩环56上的孔称为压缩孔。回弹环54和压缩环56均可分别包括一个或多个紧固孔61。如图4和图5所示，通过使紧固件69对准紧固孔61并固定来组装吸入组件50。如图5所示，回弹环54和压缩环56以镜像构造面对彼此。
吸入组件50包括回弹盘58和压缩盘60以及多个支点间隔件62，64。回弹盘58和压缩盘60还各自包括紧固孔61。回弹支点间隔件62和压缩支点间隔件64优选地是相同的。支点间隔件还包括紧固孔61。如图所示，回弹环54、压缩环56、回弹盘58、压缩盘60以及回弹支点间隔件62和压缩支点间隔件64都通过紧固件69紧固在一起，紧固件69通过上述组件的对齐的紧固孔61连接上述组件。可以使用铆钉、螺栓、螺钉或其他合适的紧固件。吸入组件50可以在吸入组件50组装到阻尼器20内之前组装好。
如在图5和图6D中最佳可见的，回弹环54和压缩环56包括靠近回弹孔55和压缩孔57的相应锥形部分71。锥形部分提供通过外管吸入孔52进入吸入组件50的流体进入。如图5所示，环100可以固定到内管26。环100可以是焊缝或夹。回弹环54和压缩环56在组装中以合适的方式、例如焊接来固定到环100。如图所示，提供一对O形环98以将回弹环54和压缩环56密封到外管24。
参考图4和图6D，可以看出回弹环54和压缩环的外径基本上对应于外管24的内径，而内径基本上对应于内管26的外径。为了允许用于回弹盘58和压缩盘60从回弹孔55和压缩件57移开的间隙，回弹盘58和压缩盘的外径小于外管的内径。类似地，回弹盘58和压缩盘60的内径大于内管26的外径。
支点间隔件64可由金属或任何其他合适的材料制成。当组装时，紧固件69和支点间隔件64提供预加载以允许合适的液压密封，从而流体在回弹冲程期间不会流经压缩环56并且类似地在压缩冲程期间不会流经回弹环54。
参考图2，将更详细地描述回弹行程。在回弹冲程期间，活塞沿箭头A的方向移动。如图所示，流体从远端内管孔排出进入流体室18。流体流经流体室18并进入主动回弹阀42。如图所示，通过抵靠压缩环56的可弯曲的压缩盘的液压密封将流体保持在吸入组件50内。主动回弹阀42由ECU25控制以提供期望的阻尼效果。流体从主动回弹阀42流出并通过外管吸入孔52。随着压缩工作室40的增大，其中的压力小于入口52和低压室84处的压力。该压力差作用在可弯曲的回弹盘58上，以移动可弯曲的回弹盘58远离回弹环54或远离回弹环54的两个回弹孔55。回弹支点间隔件62的尺寸和选择可设定为根据所需的更大或更小的流体压力来使得回弹盘58弯曲并且远离回弹孔。如图所示，流体可以根据需要从蓄能器80的低压室84流动通过外管吸入孔52。然后流体将流过近端内管孔并进入压缩工作室40，直到回弹冲程完成。
参考图3，将更详细地描述压缩冲程。在压缩冲程期间，活塞沿箭头B的方向移动。如图所示，通过流体室18和外管主动压缩阀孔93，流体从近端内管孔排出进入主动压缩阀44。通过静水压力使可弯曲回弹盘58保持与回弹孔55之间的封闭。流体在ECU25的控制下流过主动压缩阀44。随着回弹工作室的扩大，其中的压力小于入口处的压力，而压缩工作室40中的压力大于低压室84中的压力。在此，流体从外管吸入孔52进入吸入组件50并驱使可弯曲压缩盘60远离压缩孔57。如图所示，流体可根据需要流入蓄能器80的低压室84。流体流入流体室18，通过远端内管孔94并进入回弹工作室38，直到压缩冲程完成。
参考图7，示出了传统的双管阻尼器120，其不包括图2和图3的蓄能器。传统的双管阻尼器包括主动回弹阀142、主动压缩阀144以及外管124和内管126。包括活塞130的杆132包含在内管126内。活塞130和内管126限定回弹工作室138和压缩工作室140。如上所述，回弹工作室138和压缩工作室140包含流体，优选地液压油。传统的双管阻尼器包括储备管180。在传统的双管阻尼器120中，吸入组件50位于流体室118中。内管126包括与回弹工作室138流体连通的远端孔194以及与压缩工作室140流体连通的近端孔196。阻尼器120的操作类似于图2和图3所示的阻尼器20。类似于阻尼器20，通过在流体室118中包括吸入组件50可以有利地减小阻尼器120的固定长度。
已经以说明性的方式描述了本公开，并且应当理解，已经使用的术语旨在具有描述词的性质而不是限制性的。鉴于上述教导，本公开的许多修改和变化是可能的，并且可以以不同于具体描述的方式来实践本公开。
