Document Type and Number:
Japanese Patent JP2018103969
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a tire information acquisition device which is configured to reduce an influence on a riding comfort performance and a high-speed durability performance of a tire.SOLUTION: A tire information acquisition device 1 includes a sensor module 3 equipped with a sensor 2 for acquiring information on a tire 30 and a support skeleton 5 which is installed on an inner surface of the tire for supporting the sensor module 3 and is made of rubber. The support skeleton 5 is hollow, and the sensor module 3 is mounted on the support skeleton 5 in a floating state with respect to the inner surface of the tire. In addition, to further reduce an influence on riding a comfort performance and a high-speed durability performance of the tire, a difference ΔP between an inner pressure Pof the tire and a pressure Pof a gaseous matter inside the support skeleton 5 is set in a range of 50kPa≤ΔP≤150kPa, and a thickness d of the rubber of the support skeleton 5 is set in a range of 0.8 mm≤d≤1.2 mm.SELECTED DRAWING: Figure 1
