    • An axle depends from a heavy-duty vehicle. Each one of a pair of wheel end assemblies is mounted on a respective one of the ends of the axle. Each wheel end assembly includes a pair of bearings mounted on a spindle of the axle, and a wheel hub rotatably mounted on the bearings. A cavity is formed in the wheel end assembly between the bearings. A port is formed in the wheel hub and extends axially inwardly from an outboard end to a lubricant cavity of the hub, and angles radially inwardly from the outboard end to the lubricant cavity at an angle relative to an axial centerline of the hub. Lubricant for the bearings is introduced into the cavity by means of the port, and the port is tapped to receive a plug to seal it and contain the lubricant in the cavity. The port also provides a visual indicator if there is a leakage of semi-fluid grease.
    • 车轴取决于重型车辆。 一对车轮端部组件中的每一个安装在轴的相应的一个端部上。 每个轮端组件包括一对安装在轴的主轴上的轴承和一个可旋转地安装在轴承上的轮毂。 在轴承之间的轮端组件中形成空腔。 端口形成在轮毂中并且从外侧端部轴向地向内延伸到轮毂的润滑剂腔,并且相对于轮毂的轴向中心线以一角度从外侧端径向向内倾斜到润滑剂腔。 轴承的润滑剂通过端口引入到腔体中,并且端口被攻丝以接收塞以密封它并且将润滑剂容纳在腔体中。 如果有半流体润滑脂泄漏,​​该端口还提供一个可视指示器。
