Abstract
An axle assembly having a hose, a spindle plug, a sleeve, and a rotary union adapted to be fluidly connected to a tire. The spindle plug may be disposed in a spindle. The hose may be fluidly connected to the rotary union. The sleeve may encircle the hose and extend from the spindle plug to a stator of the rotary union. The sleeve cooperates with the spindle plug to limit rotation of the stator and the hose.
Claims20
An axle assembly comprising:
- a spindle that defines a spindle hole that is disposed along an axis;
- a hub that is rotatable about the axis with respect to the spindle;
- a spindle plug that is disposed in the spindle hole and is fixedly positioned with respect to the spindle, the spindle plug defining an opening;
- a hose that extends through the opening;
- a rotary union comprising a stator and a rotatable fitting that is fluidly connected to the hose and rotatable about the axis with respect to the stator, wherein the rotatable fitting is adapted to be fluidly connected to a tire;
- and
- a sleeve that encircles the hose and that extends from the spindle plug to the stator, wherein the sleeve cooperates with the spindle plug to limit rotation of the stator and the hose about the axis, wherein the sleeve extends through the opening.

An axle assembly comprising:
- a spindle that defines a spindle hole that is disposed along an axis;
- a hub that is rotatable about the axis with respect to the spindle;
- a spindle plug that is disposed in the spindle hole and is fixedly positioned with respect to the spindle, the spindle plug defining an opening;
- a hose that extends through the opening;
- a rotary union comprising a stator and a rotatable fitting that is fluidly connected to the hose and rotatable about the axis with respect to the stator, wherein the hose is received inside the stator and is coupled to the stator, and the rotatable fitting is adapted to be fluidly connected to a tire;
- and
- a sleeve that receives the hose and that extends from the spindle plug to the stator, wherein the spindle plug limits rotation of the sleeve, and the sleeve limits rotation of the stator and the hose about the axis, wherein the sleeve has a first end, a second end that is disposed opposite the first end, a sleeve hole that extends from the first end to the second end, and at least one anti-rotation feature that extends between the first end and the second end and that is disposed outside of the sleeve hole, wherein the anti-rotation feature engages the spindle plug to resist rotation of the sleeve about the axis.

- a spindle plug that is disposed in the spindle hole and is fixedly positioned with respect to the spindle, the spindle plug defining an opening;
- a hose that extends through the opening;
- a rotary union comprising a stator, a rotatable fitting, and a torque tube, wherein the rotatable fitting is fluidly connected to the hose, is rotatable about the axis with respect to the stator, and is adapted to be fluidly connected to a tire, wherein the hose is received inside the stator and is coupled to the stator, wherein the torque tube is received inside the stator and the hose and fluidly connects the stator to the rotatable fitting, and wherein the rotatable fitting is rotatable about the axis with respect to the torque tube;
- and
- a sleeve that receives the hose and that extends from the spindle plug to the stator, wherein the spindle plug limits rotation of the sleeve, and the sleeve limits rotation of the stator and the hose about the axis.
