Tire inflation system with peristaltic pump
First Claim
Patent Images
1. 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 with respect to the spindle, wherein the wheel end assembly has an axle shaft that extends through a hole in the spindle, the axle shaft having an axle flange disposed at a distal end;
a peristaltic pump that includes;
a flexible tube that rotates about the axis with the wheel end assembly, wherein the axle shaft rotates the flexible tube about the axis and the peristaltic pump is disposed between the axle flange and the spindle such that the flexible tube is spaced apart from the spindle; and
a displacement member that is disposed proximate the spindle, wherein the flexible tube is occluded by deformation of the flexible tube by the displacement member when the flexible tube rotates about the axis, thereby causing the peristaltic pump to output a pressurized gas; and
a conduit that supplies the pressurized gas from the peristaltic pump to a tire.

9. 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 peristaltic pump that is disposed proximate the axle flange and includes; a flexible tube that rotates about the axis with the axle shaft; and a displacement member that extends around the spindle, wherein the flexible tube is occluded by deformation of the flexible tube by the displacement member when the flexible tube rotates about the axis, thereby causing the peristaltic pump to output a pressurized gas; and a conduit that supplies the pressurized gas from the peristaltic pump to a tire. - View Dependent Claims (10, 11, 12, 13, 14)

15. 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 further comprises a hub hole; a peristaltic pump that is disposed proximate the hub and includes; a flexible tube that rotates about the axis with the hub; and a displacement member that is mounted to the spindle, wherein the displacement member includes a roller that rotates about a roller axis that does not move with respect to the axis, and the flexible tube is occluded by deformation of the flexible tube by the roller when the flexible tube rotates about the axis and about the displacement member, thereby causing the peristaltic pump to output a pressurized gas; and a conduit that supplies the pressurized gas from the peristaltic pump to a tire, wherein the conduit extends through the hub hole. - View Dependent Claims (16, 17, 18, 19)
