ABSTRACT:
An apparatus is disclosed for measuring tire force and tire tread motion in a common area of a tire under test. The apparatus comprises a tire test block having a bearing surface over which a tire to be tested is rolled. A force sensor is received in an opening in the block and adapted to be engagable by the tire under test. The force sensor includes a longitudinally extending member having a longitudinally extending opening therein. The member has a central axis, the central axis being oriented substantially perpendicular to the bearing surface of the test block. The force sensor further includes strain gages secured to the member and having an electrical characteristic indicative of force applied to the member by the tire under test. A motion sensor is located within the longitudinally extending opening in the member. The motion sensor includes an elongated pin having a tip extending beyond the bearing surface of the test block so that the tip penetrates the tread of the tire under test as the tire rolls over the motion sensor. The motion sensor further includes strain gages secured to the pin and having an electrical characteristic indicative of the motion of the pin which is, in turn, indicative of the motion of the tread of the tire penetrated by the pin.
