Abstract
A hub-integrated inflation system which functions to convert relative motion at the wheel end (e.g., between the axle and the hub or wheel) into a pumping motion. The relative motion is then converted into mechanical or electrical energy, which can be used to actuate a pump of an inflator.
Claims20
A hub-integrated inflation system comprising:
- a hub body defining a lubricant cavity;
- a pump mounted to the hub body;
- and
- a cam follower mechanically coupled to the pump;
- and
- a floating cam arranged within the lubricant cavity,
- wherein, in a pumping mode, the floating cam is configured to eccentrically rotate about an axis of rotation of a spindle, with the cam follower in contact with a first surface of the floating cam,
- wherein, in a non-pumping mode, the pump is disengaged.
5 more elements
A system comprising:
- a hub body configured to mount to an axle and defining an axis of rotation;
- a cam encircling a static component of the axle, the cam defining:
- a first surface with a central axis offset from the axis of rotation;
- and
- a second surface which is radially outward of the first surface;
- an output component mounted to the hub body;
- and
- a cam follower selectively connecting the output component to the second surface.
5 more elements
A system comprising:
- a hub body defining an axis of rotation;
- an output component mounted to the hub body;
- and
- a cam encircling a non-rotating axle component, the cam defining a central axis offset from the axis of rotation, wherein, in a first configuration, the output component is coupled to the cam and the cam is configured to rotate about the axis of rotation with a different angular frequency than the hub body.
