AUTOMATIC SELF-LOCKING OVERRUNNING CLUTCH FOR ONE-WAY TRANSMISSION OF REVERSE TORQUE Russian patent published in 2009 - IPC F16D7/04 F16D43/202 B25B23/14 B23B45/00 

FIELD: machine building.

SUBSTANCE: invention relates to automotive and machine building industries, particularly, to production of transmissions of multi-purpose vehicles. The overrunning clutch for one-way transmission of reverse torque comprises two driven half-couplings fitted on common shaft and rigidly jointed together and a driving two-way half-coupling. The driven half-couplings with RH- and LH-engagement ratchet teeth are fitted facing each other. The driving two-way coupling with RH- and LH-engagement ratchet teeth is fitted coaxially and between the aforesaid driven half-couplings to move axially to come into engagement with the driven half-couplings teeth. The driving half-coupling is spring-pressed to one of the driven half-couplings and is rigidly linked up with the control clutch. The latter can interact with the control yoke pressing, via another, more rigid spring, the control clutch together with the other driving half-coupling until engagement with the other driven half-coupling when torque direction varies.

EFFECT: higher cross-country capacity, road-holding ability and roadability.
