Claim Text:
1. A spatial wedging friction overrunning clutch, comprising: at least one axially engaged traction friction mechanism revolving about an axis, said traction friction mechanism comprising at least one intermediate member and a friction member revolving about said axis and provided with a traction friction surface, the intermediate member and the friction member being abutted against each other in the axial direction to form at least one traction friction pair for producing and transmitting traction friction torque therebetween; at least one rotation guide mechanism, which revolves about said axis and provides engagement force to said traction friction mechanism, wherein the rotation guide mechanism includes said intermediate member and a guide member revolving about said axis and provided with a corresponding guide surface, the intermediate member and the guide member being abutted against each other in the axial direction to form a guide friction pair, wherein a lead angle λ at the abutment position of the guide friction pair is greater than zero and smaller or equal to
