    摘要： A spindle nut and a locking device for securing the nut in a rotative position on a spindle. An anti-rotation spring and a back up plate are mounted on the spindle in a non-rotative manner with the back up plate in abutment with the bearings that rotatively mount the hub to the spindle. The back up plate has multiple grooves aligned with and arranged to receive multiple resilient tabs on the periphery of the anti-rotation spring. The tabs of the anti-rotation spring are formed to project axially from the spring. A flange of the nut has multiple slots around its periphery that are sized to receive a tab of the anti-rotation spring. A tool having extending ears that fit in the slots of the nut is utilized to install the nut on the spindle. The extending ears prevent the tabs of the spring from entering a slot of the nut until the tool is removed. As the nut is rotated by the tool, the nut abuts the anti-rotation spring. The extending ears and the face of the flange in combination force the radial tabs of the spring further into the grooves of the back up plate. When the nut is torqued to the desired level, the tool is removed allowing a tab of the spring to enter a slot of the nut due to its resiliency to lock the nut in a rotative position. Should a tab of the spring not be in alignment with a slot of the nut, the nut need only rotate a few degrees to place one of the slots of the nut in alignment with a tab of the spring.

    摘要翻译： 主轴螺母和用于将螺母固定在主轴上的旋转位置的锁定装置。 防旋转弹簧和支撑板以非旋转的方式安装在主轴上，后备板与将轮毂可旋转地安装到主轴上的轴承邻接。 后备板具有与防旋转弹簧的周边对准并布置成容纳多个弹性突片的多个凹槽。 防旋转弹簧的突片形成为从弹簧轴向突出。 螺母的凸缘具有围绕其周边的多个槽，其尺寸适于容纳抗旋转弹簧的突片。 使用具有安装在螺母的槽中的延伸的耳朵的工具将螺母安装在主轴上。 延伸的耳朵防止弹簧的突出部进入螺母的槽，直到工具被移除。 当螺母通过工具旋转时，螺母抵靠防旋转弹簧。 延伸的耳朵和凸缘的表面组合地将弹簧的径向突片进一步压入后备板的凹槽中。 当螺母扭转到所需水平时，刀具被移除，允许弹簧的突片由于其弹性而进入螺母的槽，以将螺母锁定在旋转位置。 如果弹簧的突舌不能与螺母的槽对齐，那么螺母只需旋转几度就可以将螺母的一个槽与弹簧的卡舌对准。

    摘要： A hub lock device for converting a vehicle between four-wheel and two-wheel drive, the hub lock being actuated by automatic actuation or manual actuation. A sliding clutch ring that engages and disengages the wheel and axle is trapped in a cage. An extender bar from the cage has a hook end that hooks over the edge of a nut. The nut is moved between inner and outer positions by a manual dial. In the outer position, the nut forces the cage, through engagement of the hook end, to the position whereat the clutch ring is urged to interlock the axle and wheel. In the inner position the nut releases the cage, i.e., the hook can extend between an inner and outer position, to permit automatic actuation. The automatic actuation includes cam actuation wherein the spindle nut provides the cam actuator and brake surface for secondary cam actuation. The spindle nut is locked to the spindle with a lock pin projection extended from a thrust ring that enhances turning of the drive gear on the axle relative to the spindle nut in four-wheel drive.

    摘要翻译： 一种用于在四轮和二轮驱动之间转换车辆的轮毂锁定装置，轮毂锁由自动致动或手动致动致动。 将车轮和车轴接合和脱离的滑动离合器环被夹在笼中。 笼子的延长杆具有钩在螺母边缘上的钩端。 螺母通过手动拨盘在内部和外部位置之间移动。 在外部位置，螺母通过钩端接合到促动离合器环的位置，使车笼和车轮互锁。 在内部位置，螺母释放保持架，即钩可以在内部和外部位置之间延伸，以允许自动致动。 自动致动包括凸轮致动，其中主轴螺母提供凸轮致动器和用于副凸轮致动的制动表面。 主轴螺母被锁定到主轴上，锁定销突起从止推环延伸，增强了四轮驱动时相对于主轴螺母的轴上的驱动齿轮的转动。
