FIELD: machine building.
SUBSTANCE: invention relates to field of transportation equipment, particularly to transmission gears of tractors. Kinematical connection of components of transmission gears is divided for group, containing friction elements, providing switching of all operating rates on the run, and group without friction clutches, for switching with stop. Group without friction clutches contains hydrocontrolled gear clutches with hydraulic synchroniser, providing switching of ranges of technological, transport, running and reverse movement rates. During power transfer specified operating speed range is provided by not less than by four friction hydro-pressed clutches, located only on primary and secondary shafts.
EFFECT: there is achieved simplification of structure of transmission gears mainly of agricultural purpose, efficiency upgrading.
