Abstract
A tire and wheel assembly includes a wheel having a portal and a tire mounted on the wheel, thereby forming a cavity. The assembly further includes a deflection sensor mounted on the wheel over the portal, at a location outside the cavity such that no portion of the deflection sensor is inside the cavity.
Claims20
A tire and wheel assembly comprising:
- a wheel having a through hole;
- a tire mounted on the wheel, thereby forming a cavity;
- a valve extending through the wheel, from a location outside the cavity to a location inside the cavity, wherein the valve is spaced away from the through hole;
- and
- a deflection sensor mounted on the wheel over the through hole, at a location outside the cavity such that no portion of the deflection sensor is inside the cavity.
2 more elements
A method of regulating pressure in a tire, the method comprising:
- providing a tire mounted on a wheel of a vehicle,
- wherein the tire and wheel define a cavity, and
- wherein the wheel has a through hole disposed therein;
- providing a deflection sensor on the wheel over the through hole, at a location outside the cavity such that no portion of the deflection sensor is inside the cavity;
- monitoring, with the deflection sensor, a selected area of an inner wall of the tire opposite the through hole;
- calculating a tire deflection based on the monitoring of the selected area of the inner wall of the tire opposite the through hole;
- determining a desired tire deflection of the tire based at least in part on non-tire data;
- and
- adjusting air pressure inside the tire until the calculated tire deflection is within a predetermined amount of the desired tire deflection.
