Torque Sensor choose strain gage type, the choice of the transmission mode shaft formula, and then four strain gauge make full bridge, then connect leading-out wire to four slip rings. Slip rings rotate with the axis. Electric signal transmitted to the PCM data acquisition system through brush. Taking into account the equipment used in the fields of the strain gauge the diameter, Rated torque less than 100 Nm fixation of a transmission shaft can be measured. The design references the previous design, and has an improvement, afterward with the relevant content of the references and appendices. As the design process through the three and greatly improved its service life and maintainability. Calibration device design mainly to the problem of how to feed one-end connected with spline and fixed on experimental stage with bolt and the other connected to spend bond with the loading lever rotation together, in this way have reversed, and test its axis torque, Drawing calibration curve.
