DIFFERENTIAL WITH AUTOMATIC LOCKING WHEELS Russian patent published in 2020 - IPC F16H48/20 F16H48/38 

FIELD: machine building.

SUBSTANCE: differential with automatic locking of wheels comprises two semi-axles and device for transfer of rotation from housing to semi-axles, made in form of two screw conveyors installed on axles with right and left helical grooves, interacting with housing and covers by means of closed chains of balls, arranged with the possibility of movement in covers made in housing and return channels and in hemispherical grooves, connecting these channels, wherein the outer end of each screw conveyor is provided with a helically-sprocket fixed to it, teeth of which are bent towards screw conveyor with formation between teeth section of curved surface, commensurate in length with diameter of ball and under which in each of covers is made groove, diameter of which is greater than screw conveyor diameter, characterized in that helical-sprocket sprocket is made integral with screw conveyor, in return channels elements are made to increase resistance to balls movement to increase locking ratio, housing cover has equispaced holes, above which there attached to the cover is ring made in the form of truncated cone of low height to provide forced lubrication of differential.

EFFECT: better performance is provided.
