FIELD: engines and pumps.
SUBSTANCE: invention relates to coupling drive hydraulic pumps. System for distribution of torque between front and rear axles of all-wheel drive vehicle and/or between LH and RH wheels comprises one coupling joint of increased internal resistance that has disc unit and piston for its actuation which is actuated by hydraulic pump device. Said device incorporates motor to drive the hydraulic pump and rotary regulator to control the overpressure valve connected with hydraulic pump oil outlet. In particular, this device comprises axial piston pump with piston cylinder arranged in pump housing to turn therein and including several axial pistons. The latter can reciprocate. One centrifugal lever is secured to piston cylinder to turn thereat and valve part connected with said centrifugal level and arranged to interact with oil discharge channel in piston cylinder to make the overpressure valve.
EFFECT: simplified design.
