Abstract:
1. An automatic torque calibration device connected to a torque measurement rotor of a dynamometer to execute a torque calibration of the dynamometer, wherein one end of the torque measurement rotor is configured to be connected with an output shaft of an engine and wherein the automatic torque calibration device is provided at a side of an other end of the torque measurement rotor, the automatic torque calibration device comprising: a connecting shaft rotatably provided with respect to a base platform and coaxially connected to the torque measurement rotor; a calibration arm integrally rotated with the connecting shaft and extended with respect to the connecting shaft; a moving mechanism adapted to move the connecting shaft between a connection position where the connecting shaft is connected to the other end of the torque measurement rotor and a spaced position spaced away from the other end of the torque measurement rotor; a rotating direction fixing mechanism engaged with an engaged part provided on the torque measurement rotor at the connection position so as to fix the torque measurement rotor and the connecting shaft in the rotating direction; and a control unit adapted to control the moving mechanism, wherein the control unit controls the moving mechanism to move the connecting shaft to the connection position so as to fix the torque measurement rotor and the connecting shaft to be connected in the rotating direction by the rotating direction fixing mechanism.
