摘要： A wheel end assembly that includes a hub, a hub cap, first and second spider retainers, and a spider having a spider shaft. The hub and the hub cap cooperate to define an internal cavity. The first and second spider retainers are disposed in the internal cavity and cooperate to define a spider shaft hole. The spider shaft is received in the spider shaft hole.

摘要： An axle assembly includes a spindle to receive a drive shaft having a rotational input about an axis and a wheel hub rotatably supported by at least one roller bearing disposed on the spindle. A tire inflation system defines a spindle gas passage to route pressurized gas from an onboard source through the spindle. The tire inflation system includes a seal chamber between the spindle and wheel hub to transfer gas from the spindle to the wheel hub, and a hub gas passage in fluid communication with the seal chamber is arranged to route the pressurized gas to a tire. A lubrication system having a reservoir is located axially outboard of the seal chamber and at least one hub lubricant passage routes lubricant between the reservoir to a roller bearing located axially inboard of the seal chamber. The hub lubricant passage routes lubricant radially outward of the seal chamber.

摘要： A wheel end assembly having a spindle, a hub, and a rotary seal assembly. The spindle defines a spindle air passage, a vent passage, and a spindle hole. The hub defines a hub air passage. The rotary seal assembly fluidly connects the spindle air passage to the hub air passage. The vent passage fluidly connects an inboard cavity to the spindle hole.
