alternatively, the torque setting of the clutch may reflect the pressure differential between the hydraulic pump and the hydraulic motor. In the subsequent test process, the actual torque reaches the torque set value to overcome the torque transmitted by hydraulic viscosity of the hydraulic system, so that the clutch can really reach a combined state, and the accuracy of the invention is improved without limitation.
