WIPO Patent Application WO/2021/080017
Kind Code:
A1
Abstract:
The objective of the present invention is to enable bench testing of a tire to be performed under various road surface conditions, without moving the road surface during testing, by causing a carriage which holds a test tire to travel along the road surface. A tire testing device according to an embodiment of the present invention is provided with: a road surface; a carriage which rotatably holds a test tire to which a test tire is fitted, and which is capable of traveling along the road surface with the test tire grounded on the road surface; and a guide mechanism which guides the movement of the carriage in a direction of travel. The guide mechanism is provided with a rail which extends in the direction of travel of the carriage, and a runner which is fixed to the carriage and which is capable of traveling along the rail. The runner is provided with a roller capable of rolling along the rail, and a bearing which rotatably supports the roller, wherein the bearing is a rolling bearing provided with rolling elements that roll along a circular orbit.
