TWO-WHEEL TRACTOR POWER TRANSMISSION Russian patent published in 2024 - IPC A01B71/00 

FIELD: machine building.

SUBSTANCE: power transmission of the two-wheel tractor comprises reduction gear housing (1) with an output shaft arranged inside, composed of two output half-shafts (2 and 3), fixed against axial movement and made with possibility of independent rotation relative to each other, connected to input shaft through sprocket units (6 and 7). Gearbox housing (1) is equipped with intermediate shaft (32) having driving sprocket (33) and drive sprockets (34 and 35). Input shaft is composed of two hollow input half-shafts (4 and 5), fixed against axial movement and made with possibility of independent rotation relative to each other, wherein their chambers accommodate clutch release rods (12 and 13) with release mechanisms (14 and 15) provided with individual controls (16 and 17) to allow clutch engagement and disengagement. On the outer part of hollow input half-shafts (4 and 5), drive clutches (18 and 19) are coaxially installed, equipped with drive discs (20 and 21), and driven clutches (22 and 23), equipped with driven discs (24 and 25) and pressure discs (26 and 27), which have springs (28 and 29) installed with possibility of pressing to the base of driven clutches (22 and 23) of drive and driven discs (20, 21, 24 and 25). On outer part of hollow input half-shafts (4 and 5) with possibility of axial rotation there are drive clutches (18 and 19), which outer surfaces are made in the form of driven sprockets (30 and 31) interconnected with drive sprockets (34 and 35) by roller chains (36 and 37).

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