FIELD: transportation.
SUBSTANCE: invention relates to limiting devices of differentials for a vehicle. Differential limiter for a vehicle includes: a clutch hub, a clutch drum, a clutch friction coupling, comprising plurality of frictional engagement members and piston; a drive, a screw mechanism, including element with the threaded shaft and the nut element. Rotary motion of the electric motor is converted by the screw mechanism into a linear movement of the nut element in the direction of the first axis C1 of the shaft of the side gear. Piston mounted on the nut element, moves in the direction opposite to the direction of depression of the frictional engagement members. Piston and the clutch drum are engaged without rotation concerning it. Thus differential rotation of a pair of side gears is mechanically limited.
EFFECT: invention allows the side gears pair differential rotation mechanically limitation, at that preferably reducing the vehicle differential gear limiting device size.
