Magneto-rheological elastomer wheel assemblies with dynamic tire pressure control
First Claim
Patent Images
1. A wheel assembly comprising:
- a rim;
a tire assembly engaged with the rim, the tire assembly comprising an inner tire and an outer tire, wherein the outer tire comprises an interior wall that cooperates with the inner tire to form a chamber;
a magneto-rheological elastomer (MRE) assembly disposed between the rim and the outer tire, wherein the MRE assembly is configured to adjust a tire pressure within the chamber and engage the inner tire when a magnetic field is applied to the MRE assembly.

Abstract
A wheel assembly includes a magneto-rheological elastomer (MRE) assembly disposed between a rim and a tire assembly. The MRE assembly may be configured to adjust a tire pressure within a chamber between the rim and the tire assembly when a magnetic field is applied to the MRE assembly.

16. A vehicle with a dynamically adjustable tire pressure system, the vehicle comprising:
-
a wheel assembly comprising a rim, a tire assembly having an inner tire and an outer tire, wherein the outer tire comprises an interior wall that cooperates with the inner tire to form a chamber, and a magneto-rheological elastomer (MRE) assembly between the rim and the inner tire, the MRE assembly comprising an electromagnet and an MRE pillar, wherein the MRE pillar comprises a side wall that at least partially surrounds the electromagnet; and
,a feedback control system in communication with a condition sensor and the MRE assembly, wherein when the feedback control system receives feedback signals from the condition sensor that a tire pressure is outside a preset range, the feedback control system produces a control signal to control an output of the electromagnet. - View Dependent Claims (17, 18, 19, 20)
