Abstract
A tire inflation system having a rotary coupling. The rotary coupling may have a mounting member and a rotating member. The rotating member may be rotatably coupled to the mounting member and may have a rotating member passage that may fluidly connect a first conduit to a second conduit that may be fluidly connected to the tire.
Claims21
A tire inflation system comprising:
- a first conduit for supplying a pressurized gas for inflating a tire;
- an axle housing;
- a hub that is rotatably disposed on the axle housing;
- and
- a rotary coupling that is axially spaced apart from the hub and includes:
- a mounting member that is disposed proximate the axle housing and the first conduit;
- a rotating member that is rotatably coupled to the mounting member, wherein the rotating member has a rotating member passage that fluidly connects the first conduit to a second conduit that is fluidly connected to the tire;
- and
- a mounting bracket that is fixedly disposed on the mounting member and that radially extends around the rotating member to help position the rotating member.

- a first conduit for supplying a pressurized gas for inflating a tire;
- an axle housing;
- and
- a rotary coupling that includes:
- a mounting member that is disposed proximate the axle housing and the first conduit;
- a rotating member that rotates about an axis and is rotatably coupled to the mounting member, wherein the rotating member has a rotating member passage that fluidly connects the first conduit to a second conduit that is fluidly connected to the tire and a rotating member groove that extends continuously around the axis and is disposed on an outer rotating member surface that extends around the axis;
- and
- a mounting bracket that is fixedly disposed on the mounting member and that engages the outer rotating member surface.
