Abstract
Official abstract text for this publication.
Provided is a tire testing apparatus capable of accurately and easily measuring a load which a tire receives from a road surface. The tire testing apparatus includes a plate buried in a road surface with which a tire is in contact, at least one ground-contact-force sensor measuring a ground-contact force during a contact of the tire, and at least one plate sensor measuring a load applied to the plate. According to the tire testing device, a ground-contact force of the tire can be measured by the ground-contact-force sensor and a load which the tire applies to the plate can be measured by the plate sensor.
First claim
Opening claim text (preview).
The invention claimed is: 1. A tire testing apparatus comprising: a plate buried in a road surface with which a tire is in contact; at least one ground-contact-force sensor measuring a ground-contact force during a direct contact of the tire, the ground-contact-force sensor being fixed on the plate in an embedded state and configured to directly contact the tire when the tire passes over the plate; and at least one plate sensor measuring a load applied at a plurality of positions to the plate simultaneously with the ground-contact-force sensor measuring the ground contact force, and providing output signals from both sensors that allow the determination of a centroid of the load on the plate wherein the plurality of positions of the at least one plate sensor are separately spaced from the ground-contact-force sensor. 2. The tire testing apparatus according to claim 1 , wherein output signals of the ground-contact-force sensor are obtained based on output signals of the plate sensor. 3. The tire testing apparatus according to claim 1 , wherein output signals of the ground-contact-force sensor are obtained based on output signals of the plate sensor. 4. The tire testing apparatus according to claim 1 , wherein the at least one plate sensor actuates the ground-contact-force sensor when it detects a pressure above a predetermined threshold. 5. The tire testing apparatus according to claim 1 , wherein the plate sensor further verifies the precision of the ground-contact force measured by the ground-contact-force sensor. 6. A tire testing apparatus comprising: a plate buried in a road surface with which a tire is in contact; at least one ground-contact-force sensor measuring a ground-contact force during a direct contact of the tire, the ground-contact-force sensor being fixed on the plate in an embedded state and configured to directly contact the tire when the tire passes over the plate; and at least one plate sensor measuring a load applied at a plurality of positions to the plate simultaneously with the ground-contact-force sensor measuring the ground contact force, and providing output signals that allow the determination of the load on the plate in order to verify the precision of the ground-contact force measured by the ground-contact-force sensor.
