附图说明
其他特征、优点和细节仅作为示例出现在以下详细描述中，详细描述参照附图，其中：
图1描述了根据示例性实施例的方面包括磁稳定传动轴轴承系统的车辆；
图2是根据示例性实施例的方面的磁稳定传动轴轴承系统的示意图；和
图3是根据示例性实施例的方面描述了磁稳定传动轴轴承系统的框图。
具体实施方式
以下描述在本质上仅仅是示例性的，且不旨在限制本公开内容、其应用或用途。应当理解，在整个附图中，相应的附图标记表示相同或相应的部件和特征。如本文所使用，术语“模块”或“单元”是指专用集成电路(ASIC)、现场可编程门阵列(FPGA)、电子电路、电子计算机处理器(共享、专用或群组)和执行一个或多个软件或固件程序的存储器、硬件微控制器、组合逻辑电路，和/或提供期望功能的其他适合的部件。当在软件中实施时，模块可以在存储器中具体化为非瞬时机器可读存储介质，该非瞬时机器可读存储介质是处理电路可读的并且存储由处理电路所执行的用于执行方法的指令。
根据示例性实施例，图1中以10概括地表示车辆。车辆10包括支撑本体18的框架12和动力系28。动力系28包括原动机30，其可采取马达32的形式。马达32可采取内燃机、电动马达、混合马达等的形式。马达32联接到变速器34，该变速器34反过来操作地连接到差速器36。差速器36通过第一车轴39操作地连接到第一车轮38，以及通过第二车轴43操作地连接到第二车轮42。变速器34通过传动轴46连接到差速器36。在所示示例性方面，传动轴46采取多件式传动轴的形式，该多件式传动轴具有在接头50处连接到第二传动轴构件49的第一传动轴构件48。
根据示例性实施例的方面，传动轴46通过可以邻近接头50布置的磁稳定传动轴轴承系统60机械地支撑于框架12。参照图2，磁稳定传动轴轴承系统60包括可以固定到框架12的横向构件(未单独标识)的支架70。支架70包括设置有凸缘73的基部72，该凸缘73具有第一通道76和第二通道77。第一和第二通道76和77可以容纳将支架70连接到框架12的机械紧固件(未示出)。
进一步根据示例性方面，支架70包括限定轴承接收区82(其包括内部环形表面84)的轴承支撑部分80。隔离件90布置在轴承接收区82中。隔离件90可以由弹性或柔性材料形成且包括支撑在内部环形表面84处的外部部分92，和内部部分94。内部部分94通过多个腹杆构件(其中之一以96表示)连接到外部部分92。应当理解，腹杆构件96的数量、布置和位置可以变化。内部部分94包括具有环形表面段100的开口98。轴承104布置在开口98中。轴承104包括由环形表面段100支撑的外座圈106、内座圈107，和布置在其间的多个轴承元件109。内座圈107包括通道112，该通道112可以容纳传动轴46并旋转地支撑传动轴46。
根据示例性实施例的方面，支架70支撑电磁体120，该电磁体120包括至少部分地环绕轴承104的本体123。根据示例性方面，电磁体120布置在与重力方向相反的轴承104的一侧上。然而，应当理解，电磁体120的特定位置、形状和大小可以变化。参照图3，电磁体120电连接到轴承稳定控制模块130，该轴承稳定控制模块130包括处理器134和存储器136。轴承稳定控制模块130还可电连接到车辆速度传感器140和传动轴振动传感器142。轴承稳定控制模块130基于感测的车辆状况激活电磁体120以避免传动轴46的不期望振动。一旦激活，电磁体120就将轴承104拉到轴承接收区82内的预定位置以阻止和/或修正可导致振动的传动轴46的未对准。
根据示例性实施例的方面，电磁体120可以使轴承104移位以基本上居中定位在轴承接收区82内。应当理解，电磁体120可以使轴承104移位到轴承接收区82内偏心但稳定的位置。偏心位置可能是所需的以将负载施加到隔离件90的位部分，或者从隔离件90的部分释放负载，和/或调节轴承104的刚度参数和振动性能。
根据示例性实施例的方面，轴承稳定控制模块接收来自车辆速度传感器140的有关车辆速度的输入。一旦检测到车辆10已经达到预定速度，轴承稳定控制模块130就激活电磁体120。例如，预定速度范围可以存储在存储器136中。预定速度范围可以表示与传动轴振动相关的车辆速度。轴承稳定控制模块130可以以前瞻性模式操作并使电磁体120维持在激活状态，只要车辆10以落在预定速度范围内的速度行进。进一步地，轴承稳定控制模块130可仅在车辆进入预定速度范围之前激活电磁体120，并在车辆10离开预定速度范围的短时间内维持在激活状态。
除了例如在车辆10进入预定速度范围时激活电磁体120这样预动式的，轴承稳定控制模块130还可以是反应性的并在通过传动轴振动传感器142检测到不期望振动时激活电磁体120。不期望的振动可包括超过预定振动阈值的不期望的传动轴振动。在任一模式中，轴承稳定控制模块130在车辆操作的选定模式期间维持轴承104的基本居中位置以减少振动并延长部件寿命。
尽管已经参照示例性实施例描述了以上公开内容，但本领域技术人员应当理解，可以做出各种改变且等价物可以代替其元件，而不脱离其范围。此外，根据本公开的教导，可做出许多修改以适应特定的情况或者材料而不脱离其基本范围。因此，期望的是，本发明不限于所公开的特定实施例，而将包括落在本申请的范围内的所有实施例。
