Through the technical scheme, the motor 3 drives the multi-stage gear to synchronously rotate, the oscillating bar 28 connected to the output gear shaft 26 is enabled to realize forward and reverse rotation through forward and reverse rotation of the motor 3, and two ends of the piston push rod 11 are respectively hinged with the oscillating bar 28 and the piston of the clutch main pump 1, so that the three parts form a crank-slider mechanism, the piston of the clutch main pump 1 is enabled to linearly move in the clutch main pump 1, and then disconnection and combination of a clutch are achieved; the power of the motor 3 is transmitted to the swing rod 28 through the multi-stage gear in a speed reduction and torque increase mode, and the swing rod 28 drives the piston to move, so that the transmission efficiency is high, the energy is saved, and the gear is a common part in the mechanical field, is easy to manufacture and has low cost. Therefore, the transmission actuating mechanism of the electric automatic clutch is high in transmission efficiency, energy-saving and low in manufacturing cost.

Alternatively, the gear shafts of the multi-stage gear may be collinear or parallel to each other. Thus, the gears are regularly arranged, facilitating installation of the gears in the housing 29. All the gears can be straight-tooth cylindrical gears, so that the manufacture is convenient, and the production cost is reduced. Of course, in other embodiments of the present disclosure, the gears may have tooth shapes such as a tapered tooth, for example, and the present disclosure is not limited thereto.
