Disclosed is a conical surface friction type overrunning clutch, the clutch being regarded as a basic mechanical transmission part. A first intermediate ring (3) and a second intermediate ring (4) are provided between an inner ring (1) and an outer ring (2) both able to rotate about a common axis such that force boosting transmission mechanisms are connected respectively to conical surface friction pairs in a matching manner. All of the force boosting transmission mechanisms and the conical surface friction pairs operate within a scope of parameters in which they would not lock themselves, the force boosting transmission mechanisms being in a constant meshing state, and an initial press is exerted on the conical surface friction pairs via an elastic preloading part (7) or a magnetic member. When there are tangential external component forces in different directions between the inner ring and the outer ring, the conical surface friction pairs are slidably rotating or stay in a stationary state with the effect of the force boosting transmission mechanism such that the functions of overrunning and self-locking in the overrunning clutch are realized. The present invention is also able to realize the function of preventing the overrunning clutch from overloading and slipping by means of adjusting the design parameters. |
