摘要： A tag axle assembly has a frame having a pair of hanger brackets, an upper cross tube and a lower cross tube. A pair of rocker beams having a primary pivot for pivotally mounting the rocker beam to the support frame is mounted to the frame. A suspension air spring extends between the upper cross tube and each rocker beam, and a lift air spring extends between each hanger bracket and the front end of the rocker beam. An axle seat is hingedly mounted to the rear end of each rocker beam. An upper beam having an actuator beam and a lift bar are pivotally mounted to the axle seat and to the support frame. A linear actuator extends between the support frame and the actuator beam. Inflation of the lift air spring causes the rocker beams to rotate about the primary pivots, and expansion of the linear actuator causes the actuator beam and the interconnected lift bar to raise. As the interconnected lift bar raises, it applies an upward force to the axle seats such that the axle seats rotate about the hinge pins relative to the rocker beams. Such rotation causes the axle seats to raise further out of the ground engaging position and forward. To move the suspension into ground engaging position, the lift air springs are collapsed, and the effective length of the linear actuator is reduced while simultaneously, the suspension air springs are inflated to carry load.
摘要翻译：标签轴组件具有框架，该框架具有一对悬挂架，上横管和下横管。具有用于将摇臂可枢转地安装到支撑框架的主枢轴的一对摇臂安装到框架。悬挂空气弹簧在上横管和每个摇臂之间延伸，并且升降空气弹簧在每个悬挂支架和摇臂梁的前端之间延伸。轴座铰接地安装到每个摇臂的后端。具有致动器梁和提升杆的上梁可枢转地安装到轴座和支撑框架。线性致动器在支撑框架和致动器梁之间延伸。升降空气弹簧的充气导致摇臂梁围绕主枢轴旋转，并且线性致动器的膨胀导致致动器梁和互连的升降杆升高。当互连提升杆升高时，其向轴座施加向上的力，使得轴座相对于摇臂梁围绕铰链销转动。这种旋转使得轴座进一步升高到地面接合位置并向前移动。为了将悬架移动到地面接合位置，升降空气弹簧折叠，并且线性致动器的有效长度同时减小，悬架空气弹簧被充气以承载负载。

摘要： A spinal implant for implantation in an intervertebral space is provided, such that the implant may provide a back-out prevention feature and may also provide a visual indication of whether the back-out prevention feature is engaged. The visual indication may be a contrast between a circular visible shape of the screw head and a non-circular visible shape of the screw head. The back-out prevention feature may provide engagement of a tapered thread in the screw head with an internal thread of the implant. A hard stop may also be provided. Such back-out prevention feature may also provide a torque-based indication of engagement or non-engagement of the back-out prevention feature. The implant may possess a polymeric posterior body joined to a metallic anterior body.
摘要翻译：提供用于植入在椎间空间中的脊椎植入物，使得植入物可以提供防退回特征并且还可以提供是否参与防退避特征的视觉指示。视觉指示可以是螺钉头的圆形可见形状和螺钉头的非圆形可见形状之间的对比。防退避功能可以提供螺钉头中的锥形螺纹与植入物的内螺纹的接合。也可以提供硬停止。这种防退避功能还可以提供基于扭矩的指示，以防止退出防止特征的接合或非接合。植入物可以具有连接到金属前体的聚合物后体。
