TWO-WHEEL TRACTOR TRANSMISSION Russian patent published in 2024 - IPC A01B33/08 B62D51/06 B62D11/08 B60K17/32 F16H9/24 F16H37/00 F16D13/00 

FIELD: machine building.

SUBSTANCE: two-wheel tractor transmission 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. Reduction gear housing is equipped with an intermediate shaft having a drive clutch and drive toothed pulleys. Input shaft consists of two hollow input half-shafts fixed against axial movement and made with possibility of independent rotation relative to each other. In cavities of hollow input half-shafts there arranged are clutch release rods with release mechanisms equipped with individual control elements providing clutch engaged and disengaged modes. 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 drive and driven discs. On outer part of hollow input half-shafts with possibility of axial rotation there are drive clutches, which outer surfaces are made in the form of driven toothed pulleys interconnected with the drive toothed pulleys by toothed belts.

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