Title:
TIRE EQUIPPED WITH TRANSPONDER
Document Type and Number:
Japanese Patent JP3723303
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To increase a communication distance with a transponder by connecting the conductive wire of a jointless belt as the antenna of the transponder for transferring information with the outside by using an electromagnetic wave and causing the rubber of a belt strip to be non-conductive rubber.
SOLUTION: A pneumatic tire equipped with a transponder includes a jointless belt 13A constructed by winding a belt strip 133 on the outer peripheral part of the inside of the tire along a circumferential direction, the belt strip 133 being made by coating a conductive wire 131 with non-conductive rubber. A transponder 3 using an inquiry signal from an interrogator located in the outside of the tire as its energy source electrically connects the wire 131 with the electronic circuit 32 thereof in order to use the wire 131 as a receiving/ transmitting antenna. The transponder main body 3A of the transponder 3 is constructed by connecting the electronic circuit 32 and a small antenna 33 on a printed circuit board, and the substrate upper surface of the main body 3A is coated with an epoxy resin 36.
