APPARATUS FOR TESTING FATIGUE CRACK OF TIRE

摘要

PURPOSE: A fatigue crack testing apparatus for a tire is provided to measure endurance of a tire with respect to a twist deformation of the tire by generating a shearing deformation with respect to a rotational direction of a bead section. CONSTITUTION: A fatigue crack testing apparatus includes a driving motor(1) connected to a control section in order to generate driving force. A converting section(2) is connected to the driving motor(1) so as to generate a twist movement by converting rotational force of the driving motor(1). A rotating shaft(3) is rotated by means of rotational force generated from the converting section(2). A test tire(4) is mounted on the rotating shaft(3). A clamp(6) is provided to restraint the test tire(4). One end of a connecting rod(7) is connected to the clamp(6). The other end of the connecting rod(7) is connected to a supporting frame(5).
