Title:
DEVICE FOR MEASURING ROLLING RESISTANCE OF TIRE
Document Type and Number:
WIPO Patent Application WO/2010/101159
Kind Code:
A1
Abstract:
The rolling resistance of a tire is accurately measured. A device (1) measures the rolling resistance (Fx) of a tire (T) by pressing the tire (T) against a travel simulating road surface (2) having an endless configuration. The device (1) is provided with: a carriage (4) which has mounted on one end side thereof a tire spindle (8) for rotatably holding the tire (T); a load applying base (5) to which the other end side of the carriage (4) is connected so as to be rockable about a rocking shaft provided parallel to the rotation shaft of the tire and which applies a load to the tire (T) by moving the carriage (4) to the travel simulating road surface (2) side in such a manner that the axis of the rocking shaft is located on an extension line which connects the rotation center of the tire (T) and the contact point of the tire (T) with the travel simulating road surface (2); a pressing load measuring section (12) which measures the load applied from the load applying base (5) to the tire (T); and a rolling resistance measuring section (10) which measures the rolling resistance from a force applied to the carriage (4) in the direction tangential to the tire (T). The rolling resistance measuring section (10) can move in the direction of the movement of the load applying base (5).
