Title:
TIRE ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2022/180916
Kind Code:
A1
Abstract:
This tire assembly is provided with a tire to be mounted on a vehicle, an elastic body arranged on the inside of the tire, and a power generator disposed between an inside surface of the tire and the elastic body. The power generator is provided with a first member and a second member. The first member has a first insulating film forming a first surface. The second member has a second insulating film forming a second surface that faces opposite the first surface and is in contact with the first surface. The first member and the second member are configured so that the true contact surface area between the first surface and the second surface changes depending on the pressure applied to the first member and the second member. The first insulating film and the second insulating film are configured so that the change in the true contact surface area causes one to become positively charged and the other to become negatively charged. The elastic body urges the power generator toward the inside surface of the tire.
