The present invention relates to a tire wedge impact tester which measures and evaluates tire rigidity by applying impact by a wedge protrusion to a dynamic tire inside a room and, more particularly, to a tire wedge impact tester which can measure and evaluate the tire rigidity according to various automotive conditions by mounting two tires at one test. For this, the tire wedge impact tester measures the breaking strength of the tire by the impact of the wedge protrusion (3) which is attached to a rotary drum (2) rotating on a rotary shaft (1) and is in contact with the tires (5) attached to a spindle (4). The tire wedge impact tester has a structure where one front end of the spindle (4) is installed on a shielding wall (6), the other front end of the spindle is connected with upper and lower hydraulic cylinders (7a, 7b), and the other end of the upper and lower hydraulic cylinders (7a, 7b) is respectively attached to the test tires (5) having each suspension (8) to be in contact with the rotary drum (2). |
