FIELD: transport.
SUBSTANCE: proposed differential comprises differential gearing with central gear wheels rigidly engaged with drive wheel semi-axles 16, 16', locking device including servo drive, coupler with its drive half-coupling 14 rigidly engaged with pinion frame 17 while driven half-coupling 13 is fitted in splines of one of said semi-axles to axially displace thereon and engaged with servo drive. Control member comprises angular speed transducers, measurement and comparison circuit with its output connected to servo drive, hydraulic pumps 3, 3' coupled with semi-axles and, via hydraulic lines, with double-sided hydraulic cylinder 7. Hydraulic cylinder pistons are coupled with spring-loaded rods 8, 8' coupled, in their turn, with control cylinders 9, 9' to shut off in turn said hydraulic lines 11, 11'. Note here that shut0ff hydraulic line communicates with control cylinder 12 of servo drive via check valve 20 and restrictor 21.
EFFECT: simplified automatic locking, faster operation.
