MOTOR CULTIVATOR POWER TRANSMISSION Russian patent published in 2024 - IPC A01B71/00 

FIELD: machine building.

SUBSTANCE: device comprises a 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 units of sprockets (6 and 7). Reduction gear housing (1) is equipped with intermediate shaft (32) having driving clutch (33) and drive sprockets (34 and 35), and input shaft consists of two hollow input half-shafts (4 and 5), fixed against axial movement and made with possibility of independent rotation relative to each other. In cavities of hollow input half-shafts (4 and 5) there are clutch release rods (12 and 13) with release mechanisms (14 and 15), equipped with individual controls (16 and 17), providing clutch engaged and disengaged modes. On the outer part of the 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) 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: enabling reduction of labour intensity of motor cultivator control during manoeuvring, increase of its cross-country capacity, as well as increase of resource of clutch in power transmission of motor cultivator.
