WHEELED VEHICLE DIFFERENTIAL GEAR Russian patent published in 2009 - IPC F16H48/20 B60K17/16 

FIELD: machine building.

SUBSTANCE: invention relates to vehicles, in particular to self-locking differential gears and can be used in both transfer box and wheel gears. The propose vehicle differential gear comprises the housing, final drive, differential gear housing with half shaft gears and cams fitted therein. The said half shaft gears are in mesh with differential pinions. The said cams are helically-cammed with half shaft gears to get in contact with the push rods furnished with rollers. The thrust bearing is fixed on the reduction gear housing, the bearing movable race features a cam-like surface to interact with push rod rollers. The bearing cage inner surface features helical grooves or a diametral bore with through holes. The coupling holds the cage down to the thrust bearing fixed race with the help of plate spring.

EFFECT: mechanical control over differential gear capable of distinguishing between slipping and normal operating conditions.
