Abstract RU 2486070 C1

FIELD: transport.

SUBSTANCE: invention relates to automotive transfer boxes with automatic redistribution of torques. Transmission comprises clutch, stepped gearbox, and transfer box with master differential. Said master differential comprises three planetary gear sets switched by toothed coupling 27. Toothed coupling 27 is hydraulically driven by piston 28 arranged in three-section working chamber accommodating said piston 28 and larger-diameter piston 30 that makes a thrust for piston 28. Working chamber front section located ahead of piston 28 and medium section located between pistons are communicated via hydraulic lines with two-position hydraulic control valve 33. Working chamber rear section is communicated via hydraulic line with valve 36 communicating said rear section in turns with front section and drain line. Hydraulic control valve 33 is controlled by solenoid 37 connected to gearbox high gear IN pickup 39. Hydraulic control valve 36 is controlled by solenoid 40 connected to gearbox low gear IN pickups 42, 43. Accessory electric circuit 44 incorporating inductor 45 and condenser 46 is connected to electric circuit connecting electromagnet 40 with pickups 42, 43. Contact 49 of self-reset relay 50 connected to third stage throw-in pickup 51 is arranged parallel with condenser 46.

EFFECT: higher efficiency.
