In this process, the spring bears the impact of the clutch steel sheet and the input shaft of the gearbox, and at the same time, transmits power to the input shaft of the gearbox, increasing the rotating power. When the rotating speed of the clutch and the input shaft of the gearbox is equal, the torsion force decreases, and the spring relieves and recovers;
