FREEWHEEL SELF-LOCKING DIFFERENTIAL Russian patent published in 2014 - IPC F16H48/24 F16H48/16 B60K17/16 

FIELD: transport.

SUBSTANCE: invention relates to machine building, specifically to differential gears of wheeled tractor front driving axles, as well as can be used as differential for wheeled vehicles and other transport means. Freewheel self-locking differential represents double-acting coupled ratchet free-wheel clutch installed on bearings in axle body. It contains differential housing with driven gear (3) of central gear group. In the borings of the housing, ratchets (5) and spring-loaded axes (7) with catches (8) installed on them are mounted. The axes have on their each butt end one main eccentric projection (A), interacting with stationary disc (10) installed in axle body, and one additional projection (B) located diametrically opposite to the main projection. In the axle body there is additional disc (12) installed being able to move in axial direction by means of guides (11) and to act on additional projections.

EFFECT: invention has possibility of forced locking differential ratchet mechanisms and switching on front wheels during braking.
