PORTABLE TREAD WEAR MEASURING APPARATUS BY USING REFLECTION PLATE

摘要

PURPOSE: A portable tread wear measuring apparatus is provided to achieve reproducibility of data and to improve measuring reliability by measuring a total profile of a tire tread and depth of the tire tread. CONSTITUTION: A portable tread wear measuring apparatus includes a laser sensor(D) capable of measuring a profile and depth of a tire tread. A reflection plate(E) is positioned in a predetermined position apart from the laser sensor(D) by predetermined distance. A guide bar(F) is provided with a servo motor for moving the laser sensor(D) right and left on a tire tread surface. A fixing section(B) is positioned at the center of a tire rim. The fixing section(B) has a servo motor for controlling the laser sensor(D) and the reflection plate(E) in such a manner that the laser sensor(D) and the reflection plate(E) are rotated along the tire tread surface. A controller(A) is connected to the laser sensor(D) and the guide bar(F).
