<p>An apparatus for testing endurance of a knuckle for a vehicle is provided to prevent a linear actuator from being broken and reduce the test cost. An apparatus for testing endurance of a knuckle for a vehicle comprises a linear actuator(10), a swivel link(11) and an LM unit(12). The linear actuator is connected with a specimen through a rod and provides excitation force. The swivel link moves in X, Y and Z-axis directions according to movement of the linear actuator by employing one point as a fixed point and the other point as a moving point. The LM unit supports the moving point of the swivel link. The LM unit includes an X-axis LM block/guide(16) and a Y-axis LM block/guide(17). The X-axis LM block/guide guides movement in the X-axis direction of the moving point of the swivel link. The Y-axis LM block/guide is disposed perpendicularly below the X-axis LM block/guide.</p> |
