Abstract
The invention discloses an electric finger pin type static engagement one-way clutch. When an electric finger pin valve is not powered on, under the action of a return spring, the tail end of an electric finger pin does not make contact with the end face of an output disc, and the output disc is in a disengagement state. When the electric finger pin valve is powered on, the electric finger pin moves in the direction of the output disc in a manner of overcoming the elasticity through electromagnetic force and then slides into an arc annular groove under the rotating state, the output disc is pushed to synchronously rotate, accordingly, an input disc and the output disc synchronously drive, and the clutch is engaged.
