Abstract
A tire inflation system having a spindle, a pump actuating member, and a pump. The pump actuating member may actuate the pump when the pump rotates about an axis, thereby causing the pump to output a pressurized gas.
Claims20
A tire inflation system comprising:
- a spindle that extends along an axis;
- a wheel end assembly that is rotatably disposed on the spindle and configured to rotate about the axis and with respect to the spindle, wherein the wheel end assembly receives an axle shaft having an axle flange;
- a pump actuating member that is disposed proximate the spindle;
- a pump that is disposed proximate the axle flange and that rotates about the axis with the wheel end assembly, wherein the pump actuating member actuates the pump when the pump rotates about the axis, thereby causing the pump to output a pressurized gas;
- and
- a conduit that supplies the pressurized gas from the pump to a tire.

A tire inflation system comprising:
- a spindle having a hole;
- an axle shaft that extends through the hole and that is configured to rotate about an axis with respect to the spindle, wherein the axle shaft includes an axle flange disposed proximate a distal end;
- a pump actuating member that is fixedly disposed on the spindle and that extends around the spindle;
- a pump that is disposed proximate the axle flange and rotates about the axis with the axle shaft, wherein the pump actuating member actuates the pump when the pump rotates about the axis, thereby causing the pump to output a pressurized gas;
- and
- a conduit that supplies the pressurized gas from the pump to a tire.

A tire inflation system comprising:
- a spindle that extends along an axis;
- a hub that is rotatably disposed on the spindle and configured to rotate about the axis, wherein the hub has a hub hole;
- a pump actuating member that is fixedly disposed on the spindle and that extends around the spindle;
- a pump that is disposed proximate the hub and rotates about the axis with the hub, wherein the pump actuating member actuates the pump when the pump rotates about the axis, thereby causing the pump to output a pressurized gas;
- and
- a conduit that extends through the hub hole and supplies the pressurized gas from the pump to a tire.
