Problems solved by technology

Therefore, depending on the influence of the driving / braking force applied to the tire, even if the offset of the tire in the X direction is corrected, the measurement point does not always reach the position of the sensor, whereby an error occurs, which leads to low reproducibility

Embodiment Construction

[0018] Exemplary embodiments of the tire performance measuring method and the tire performance measuring apparatus according to the present invention will be described in detail below with reference to the accompanying drawings. The following description does not limit the invention. The constituent elements of the embodiments described below include elements replaceable or easily conceivable by those skilled in the art, or elements substantially equivalent to these elements. Although the tire performance measuring method and the tire performance measuring apparatus according to the present invention can be applied to measuring ground contact pressure, shear stress, and slippage amount of tires, measurement of ground contact pressure will be described below as an example.

Abstract

At least one of ground contact pressure, shear stress and amount of skidding is measured at a measurement point (P) on a tread surface (4) of a tire (1). A sensor (3) is arranged on a road surface (2) and the measurement point (P) is made to contact the sensor while the tire rotates. An initial position of the tire is set, where the measurement point is at a previously-set reference position (D1) and the tire is at a running start position on the road surface. The tire is made to run from the initial position to obtain a rotation angle (Theta) difference between a tire rotation angle until the rotation axis (O) of the tire passes over the arrangement position of the sensor and a tire rotation angle Theta until the measurement point contacts the road surface. The tire is set at the initial position and rotated by without changing the running start position of the tire.

Description

technical field [0001] The present invention relates to a method for measuring at least one of ground contact pressure, shear stress and amount of skidding of a tire. Background technique [0002] Generally, in order to evaluate the performance of the tread surface of a tire, the tire's ground contact pressure, shear stress, and slippage are measured. For measurement, measurement points are set on the tread of the tire, and the tire is rolled on a flat plate for measurement under predetermined conditions. A measuring point on the tread is brought into contact with a sensor embedded in the plate. Before actual measurement, alignment processing is performed. In this alignment process, the measurement points on the tire tread are completely aligned with the positions of the sensors provided on the flat plate. An example of a known alignment process is described in Japanese Patent Application Publication H3-78636, which discloses a method for measuring the ground contact pres...
