[0026] During installation, firstly, the device is mounted on the vehicle body via the balance bar connecting rod body 3. Then, the rear axle balance bar body 1, connector body 2, and balance bar connecting rod body 3 are mounted with the assistance of the mounting bracket 7 and positioning bracket 8. Next, the mounting plate 5 is installed and fixed via the connecting pipe 4 and the extension mounting rod 6.

Next, the rotating ring 20 and connector body 2 are fixed via the second fixing hole 21, and the torque strain gauge is mounted via the second mounting groove 22. Finally, the rotating ring 20 and connector body 2 are fixed via the second fixing hole 21, and the torque strain gauge is mounted with the assistance of the second mounting groove 22.

Torque strain gauges are installed through the first device bracket 16, the second device bracket 17, and the first mounting groove 18, and the wiring is installed and accommodated through the wire groove 14 and the wire hole 19. This solves the problem that most existing torque sensors have a rotating shaft mounting structure. During use, the torque is determined by connecting to the power structure through the rotating shaft. However, the rear axle balance bar is relatively integrated, and the torque sensor is relatively fixed during force measurement, which increases the difficulty of maintenance and replacement of the rear axle balance bar, resulting in a decrease in the efficiency of the adaptive adjustment torque sensor.
