HIGH-MANOEUVRABILITY TWO-WHEEL TRACTOR TRANSMISSION DEVICE Russian patent published in 2024 - IPC A01B71/00 A01B33/08 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, namely, to agricultural mechanization means. High-manoeuvrability two-wheel tractor transmission device comprises a gearbox housing with an output shaft made up of two output half-shafts fixed against axial movement and made with possibility of independent rotation relative to each other, connected to input shaft through blocks of sprockets. Gearbox housing is equipped with an intermediate shaft having a drive cardan joint and drive pulleys, and input shaft is made up of two hollow input half-shafts fixed against axial movement and made with possibility of independent rotation relative to each other, wherein their chambers accommodate clutch release rods with release mechanisms provided with individual control elements to allow clutch engagement and disengagement. At that, on the outer part of the hollow input half-shafts there are coaxially installed drive clutches equipped with drive discs, and driven clutches equipped with driven discs and pressure discs, which have springs installed with possibility of pressing to the base of driven clutches of driving and driven discs. At that, on external part of hollow input half-shafts with possibility of axial rotation there installed are drive clutches, external surfaces of which are made in the form of driven pulleys interconnected with drive pulleys by V-belt.

EFFECT: reduced manoeuvrability of two-wheel tractor control during manoeuvring, increased cross-country capacity, as well as increased service life of clutch.
