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

FIELD: agriculture; machine building.

SUBSTANCE: invention can be used in agricultural works mechanization means. Two-wheel tractor power transmission device comprises gearbox housing (1) with output shaft located inside. Output shaft consists 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 blocks of sprockets (6) and (7). Gearbox housing (1) is equipped with intermediate shaft (32) having drive pulley (33) and drive sprockets (34), (35). 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 the cavities of hollow input half-shafts (4) and (5) there are rods (12) and (13) for disengaging the clutch with release mechanisms (14) and (15), which are equipped with individual control elements (16) and (17), which provide modes of on and off disengaged clutch. On the outer part of hollow input half-shafts (4) and (5) there are coaxially installed driving clutches (18) and (19) of the clutch equipped with driving discs (20) and (21) and driven clutches (22) and (23) of the clutch equipped with driven discs (24) and (25) and pressure discs (26) and (27). Springs (28) and (29) are installed with possibility of pressing to the base of driven couplings (22) and (23) of engagement of driving and driven discs (24) and (25). On outer part of hollow input half-shafts (4) and (5) with possibility of axial rotation there are driving clutches (18) and (19), which outer surfaces are made in the form of driven sprockets (30) and (31) interconnected with driving sprockets (34) and (35) by roller chains (36) and (37).

EFFECT: reduced labour intensity of tiller control during manoeuvring, increase of its cross-country capacity, as well as increase of clutch resource.
