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

FIELD: mechanical engineering.

SUBSTANCE: power transmission of two-wheel tractor comprises a gearbox housing with an output shaft arranged inside, composed 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 intermediate shaft with drive sprocket 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 driving and driven discs. On outer part of hollow input half-shafts with possibility of axial rotation there installed are driving clutches, outer surfaces of which are made in the form of driven toothed pulleys interconnected with driving 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.
