[0004] The prior art has the following deficiencies: the prior engine clutch has only one operating mechanism or system to achieve the separation and engagement of the clutch. Thus, in an automatic transmission engine, the clutch can usually only be separated and engaged by a clutch actuator through electrical or hydraulic control. Thus, when a control system fails, the clutch cannot be controlled. Utility Model Content

[0006] In order to facilitate spatial arrangement and avoid mutual interference of control mechanism structures, the operating arm one and the operating arm two are coaxially connected structures, the operating arm one and the operating arm two are respectively connected to the two ends of the operating rod, and the middle part of the operating rod is connected to the push rod.

[0007] In order to facilitate independent control, double eccentric surfaces are provided at both ends of the operating rod, and a single eccentric surface is provided at the connection between the operating arm 1 and the operating arm 2 and the operating rod. The single eccentric surfaces of the operating arm 1 and the operating arm 2 are respectively fitted with different surfaces of the double eccentric surfaces at both ends of the operating rod.

[0008] Preferably, the double eccentric surfaces are in a fan-shaped structure as a whole, and the included angle of the fan-shaped structure is less than 180°, and the single eccentric surface is in a semicircular structure as a whole.

[0011] Preferably, the operating arm one and the operating arm two are arranged in opposite directions, with the connecting end of the operating arm one facing upwards and the connecting end of the operating arm two facing downwards.

[0012] The utility model has the following beneficial effects:

[0013] 1. The present application combines the manual switching clutch with the automatic switching clutch, and rotates the operating arm through automatic and manual control respectively, causing the clutch push rod to move axially, thereby controlling the separation and combination of the clutch.
