FIELD: machine building.
SUBSTANCE: facility for reduction of rigidity of machine tractor aggregate (MTA) transmission consists of a planetary gear, reactive link of which is coupled with gear of oil pump drive connected to suction and pressure lines. The planetary gear with its carrier shaft is coupled with a box gear and is driven from an engine. A double-step regulated throttle, a damping valve connected parallel to the throttle, a hydro-tank and a pneumatic hydro-accumulator are installed in the pressure line. A brake of a sun gear and a hydro-distributor of brake control over the sun gear braking the oil pump and blocking the mechanism are arranged on the same shaft with the sun gear.
EFFECT: raised efficiency of mechanism.
