Description

驱动桥用液压拨叉式钢球锁止差速锁
技术领域
本实用新型属于车辆领域，涉及一种驱动桥用液压拨叉式钢球锁止差速锁。
背景技术
目前，国内主流的车辆部件中，驱动桥所用的差速锁通常有机械式和齿面式两种。机械式差速锁一般要在停车状态下切换，而且过早按上或过晚摘下差速锁，即使在路况较好的情况下，左、右车轮仍为刚性连接，这种状况会对车辆的轮胎造成严重的磨损；而齿面式差速锁不可手动控制，必须等到转速差出现的时候才起作用，反应速度略慢。这两种形式的差速锁虽然使用功能较好，可以使驱动轮获得有效的驱动力，但是前者操作繁琐，后者造价成本较高。
实用新型内容
本实用新型的目的在于提供一种可靠性好、耐高温、结构紧凑、维修方便、能保证获得足够的驱动力的驱动桥用液压拨叉式钢球锁止差速锁。
本实用新型的技术方案是：驱动桥用液压拨叉式钢球锁止差速锁包括滑动接合套，导向键，钢球，中央壳体，衬套，活塞杆，耐磨带，O型密封圈，压缩弹簧，弹簧座，轴用限位挡圈，孔用限位挡圈，锁紧螺母，拨叉，差速器。将钢球镶嵌于差速器的槽部，使其转动灵活自如，滑动接合套通过导向键安装在差速器上；衬套采用均衡压力压装于中央壳体上，其端面与中央壳体孔口平齐；活塞杆套入衬套孔内，通过孔用限位挡圈固定；拨叉通过锥面配合固定于活塞杆上，其卡爪通过调整滑动接合套前后位置，固定于滑动接合套的开槽处，通过锁紧螺母固定。
耐磨带、O型密封圈、压缩弹簧、弹簧座及轴用限位挡圈依次套在活塞杆上。
本实用新型采用上述技术方案后产生的积极效果是：车轮打滑时保证其他驱动轮可以获得足够的驱动力，反应速度快，锁紧系数高，效能安全可靠，而且生产成本低，从而扩大了液压拨叉式钢球锁止差速锁的应用范围，不仅可用于拖拉机和轮式挖掘机，而且更受到井下运输机械等有特殊要求的工程机械的青睐。
附图说明
附图为本实用新型驱动桥用液压拨叉式钢球锁止差速锁的结构示意图。
具体实施方式
如附图所示，在本实施例中，驱动桥用液压拨叉式钢球锁止差速锁由滑动接合套1，导向键2，钢球3，中央壳体4，衬套5，活塞杆6，耐磨带7，O型密封圈8，压缩弹簧9，弹簧座10，轴用限位挡圈11，孔用限位挡圈12，锁紧螺母13，拨叉14，差速器15组成。将钢球3镶嵌于差速器15的槽部，使其转动灵活自如，滑动接合套1通过导向键2安装在差速器15上；衬套5采用均衡压力压装于中央壳体4上，其端面与中央壳体4孔口平齐；耐磨带7、O型密封圈8、压缩弹簧9、弹簧座10及轴用限位挡圈11依次套在活塞杆6上，使其进入衬套5孔内，通过孔用限位挡圈12固定；拨叉14通过锥面配合固定于活塞杆6上，其卡爪通过调整滑动接合套1前后位置，固定于滑动接合套1的开槽处，通过锁紧螺母13固定。
工作状态时，即有一侧的驱动轮打滑时，由制动总泵来的压力油进入油腔，推动活塞杆6；当压力达到一定程度时，活塞杆6被推开，带动拨叉14推起滑动接合套1向前运动，活塞杆6运动到弹簧座10的位置处，滑动接合套1压下钢球3，镶嵌在差速器15的半轴齿轮槽底部，锁止半轴齿轮，从而将差速器壳与半轴锁紧成一体，使差速器15失去差速作用，可以把全部扭矩转移到另一侧驱动轮上，获得足够的驱动力，摆脱困境。
系统断油后，活塞杆6在压缩弹簧9推动下，将拨叉14、滑动接合套1复位，使得钢球3松开，从而恢复了差速器15的差速功能，也使整机快速正常行驶。
