Abstract
本发明公开了可控阻尼的外部磁流变智能悬架***、控制方法及车辆,包括悬挂油缸、连接管、磁流变控制单元和储能器;磁流变控制单元位于悬挂油缸和储能器之间,三者之间通过连接管进行连接;悬挂油缸、磁流变控制单元和储能器之间设有磁流变液;当悬挂油缸压缩和延伸时,与储能器一起传导磁流变液来回流动,对磁流变控制单元施加外加电流时,磁流变控制单元中的电磁场促使磁流变液发生"凝固",从而影响磁流变液的流动速度和悬架***阻尼的大小;通过增加和降低外加电流,从而提高和降低电磁场强度,以便调整***阻尼。本发明可以有效提升车辆的环境适应性、舒适性和***可靠性,提升车辆作业效率,同时可以降低设计和制造工艺难度,降低成本。
Description
本发明涉及一种可控阻尼的外部磁流变智能悬架***,悬挂油缸与车轴或轮毂相连,是车辆悬架***的组成部分,悬挂油缸将容许悬架***运动的发生并为运动提供阻尼,悬挂油缸的应用非常普遍,但不限于矿业施工机械、农业机械、军用和道路车辆等。因此,本发明属于车辆技术领域。
矿用自卸车使用工况特别恶劣,颠簸严重,可靠的悬架***是保证车辆正常运行和驾驶员驾乘舒适性和安全性的关键。随着液压***的不断成熟和成本的降低,目前矿用自卸车的悬架***多采用了油气悬架的形式,取代了钢板簧悬架,舒适性得到一定提升。
悬架***能够使用外部储蓄器/蓄能器,根据油缸的压缩来改变悬架的阻尼性能。当油缸内的活塞被压入时,来自油缸的流体通过连管被强制压入储蓄器/蓄能器。通过适当控制初始体积和压力,可以对简单的加压油缸进行更高的阻尼控制。具有不同设定压力的多个蓄能器蓄压室可以根据油缸的压缩情况提供不同程度的悬架阻尼。但是,这仍然限于初始设定压力,而且如果没有对压力进行检查和维持,性能会随着时间逐渐降低。现有的矿用自卸车悬架***无法实现对悬架阻尼的主动控制,来适应不同的工况。可靠性、舒适性和安全性有待进一步提升,来满足不断提升的矿山运行需求。
CN202110025564.0和CN202110838279.0各自公开了一种矿用自卸车油气悬架***,是一种采用常规油液的联通式平衡悬架,使用了外部的储蓄器/蓄能器,通过连管与悬挂油缸相连,属于阻尼不可控***,在车辆受到地面冲击较大时,减震效果不良,不平地面产生的振动会传递至车架及驾驶室,造成车架主体开裂、驾驶室舒适性差等问题。
磁流变液(MR)是一种智能流体,它是一种基础液,通常是油液,其作用是使微米或纳米级的磁性颗粒悬浮。当磁流变液暴露于磁场时,它的性质会改变。这是因为当该流体内的磁性粒子与磁场一致时,流体会“凝固”,它的粘度会随着磁场强度的增加而增加。该原理被运用于磁流变油缸,当磁流变液流经活塞内的通道时,油缸活塞内的磁铁会增加磁流变液的粘度。活塞内的磁铁使磁流变液的粘度发生迅速而精确的变化,从而控制活塞运动的阻力以及油缸的性能。
CN201911181952.7一种磁流变弹性体的液压油缸,介绍了一种磁流变控制油缸结构,是一种油缸本体磁流变结构。缸内空间受限,结构较为复杂,而且为了与该配置和应用的悬挂油缸尺寸相匹配,每一个部件的体积较小,无法适应矿山恶劣工况的使用条件。另外,在油缸上设计和安装可控磁铁,制造工艺很复杂,导致工艺装备及生产成本高昂。
