现有的磁流变减振器经过二十多年的不断研究改进，在性能上已经能够满足车辆设计的要求，但结构上的不足加大了磁流变减振器的加工装配难度，从而增加了成本，不利于进一步推广应用，例如授权专利CN201010621508.5所介绍的磁流变减振器活塞结构就代表了现有磁流变减振器的结构特点，即将活塞周向开槽来布置线圈，活塞杆内部开长孔用来引出导线。该方案结构紧凑，但是活塞结构复杂，加工难度大，尤其是活塞杆，长孔的加工成本更高且在结构优化上存有较多限制。同时，减振器通过阻尼作用将震动能量转化为热能耗散掉，但温升会严重影响减振器的性能。因为利用线圈产生磁场，线圈本身会有热量产生，将线圈布置在液压缸体内部，产生的热量会进一步加剧减振器内的温升作用，降低减振器性能。
因此，设计不同结构的磁流变减振器已解决现有的问题是十分必要的，具有广阔的应用前景和经济价值。
实用新型内容
为了解决上述问题，本实用新型提出一种外置线圈的磁流变减振器，该减振器将线圈布置在液压缸体的外面，通过巧妙的结构设计，不仅使磁流变减振器达到了应有的性能要求，同时具有结构简单、散热方便、成本较低、便于维护的优点。
为了达到上述目的，本实用新型的技术方案是：

所述活塞、活塞杆、套筒、线圈、外部缸筒等相对静止，且保证水平方向上活塞位于双级线圈中央位置。所述套筒外部为光滑圆柱面，内部从上到下依次包括：第一防尘圈凹槽，第一线圈凹槽、导向环、第二线圈凹槽、第二防尘圈凹槽。所述套筒同时具有线圈、防尘圈安装定位与所述液压缸筒运动导向的作用。所述套筒内部导向环上开有轴向凹槽，用以布置连接导线。所述外部端盖具有定位所述套筒的功能，在安装后与所述套筒形成的凹槽用于安装所述防尘圈。所述外部缸筒内部上端内径大，下端内径小，上端内径与所述套筒外径相同，内径变化处为凸台结构，与所述外部端盖配合固定所述套筒。
本实用新型的有益效果是：
1、将内置的线圈改为外置，简化了磁流变减振器的内部结构，降低了加工与装配难度，节约了加工时间与加工成本。
2、线圈外置，当线圈发生故障时可以进行维修，不会影响减振器液压缸体内部结构，也不会污染磁流变液。

如图4所示为磁流变减振器线圈5工作时减振器磁场磁路结构示意图。两个线圈5串联连接但是反向缠绕，产生的磁场在同极相斥的原理下形成如图4所示的磁场结构，磁场从两个线圈5间水平通过液压缸体1，并与活塞7与液压缸体1间的阻尼通道17垂直，液压缸体内壁与间隙18之间形成一个虚拟的阻尼通道17。
当磁流变减振器工作时，液压缸体1在外力的作用下相对于活塞7与套筒6等部件上下往复运动，压迫磁流变液通过阻尼通道17而使减振器产生阻尼力。通过控制线圈5内电流的大小来控制通过阻尼通道17的磁场强度，从而改变阻尼通道17内磁流变液的流变特性，进而改变减振器的阻尼力，从而达到对阻尼力智能控制的目的。
本实用新型将原来的内置线圈改为外置线圈，简化了磁流变减振器的内部结构，降低了加工与装配难度，节约了加工时间与加工成本，而且维修方便，也不会污染磁流变液，线圈外置有利于线圈热量散失，不会加热磁流变液，有利于减振器散热与维持性能的持久稳定性，延长了使用寿命。
