Abstract
The invention discloses a lower pair arc stop-block overrunning clutch comprising an outer rotating element, an inner rotating element, a friction block assembly, a wedge assembly, a first propeller assembly, a first elastic element and a synchronized push-block assembly, wherein a plurality of friction blocks of the friction block assembly are connected end to end and arranged between a first rotating ring and a second rotating ring; an drive element drives the first propeller assembly to press the synchronized push-block assembly to achieve synchronization of the friction block assembly; the first propeller assembly is stationary relative to the friction block assembly, the friction block assembly is pushed to rotate reversely with a driven element; the wedge assembly is wedged to generate a radial pressure on the friction block assembly so that the friction block assembly can achieve lower pair arc stop, thereby achieving the transfer of torque.
