TRAILED ASYMMETRIC MACHINE RECTILINEAR MOTION STABILIZING DEVICE Russian patent published in 2025 - IPC A01D75/28 A01B59/41 B60D1/00 

FIELD: agriculture.

SUBSTANCE: trailed asymmetric machine rectilinear motion stabilizing device comprises traction lever including front part (1) connected to tractor (2) via hinge joint (3), and rear part (4) connected by means of fixed attachment to frame (5) resting on movement support surface through left wheel (6) located in the side opposite to the trailed machine asymmetric part, and right wheel (7) located in the side of the asymmetric part of the machine. Front and rear parts (1 and 4) of traction lever are connected to each other by telescopic connection. Rear part (4) of the traction lever is made in the form of a pipe, inside of which there is front part (1) of the traction lever and tension spring (8) connected by one end to front part (1) of the traction lever, the other end being connected to rear part (4) of traction lever. On rear part (4) of the traction lever there is feeding hydraulic cylinder (9) of one-way action, rod (10) of which is connected to front part (1) of the traction lever. Left support wheel (6) has a smaller diameter in comparison with right wheel (7). Left and right support wheels (6 and 7) are fixed by means of fixed connections on shafts (12 and 14) installed in bearings (13 and 15) fixed on frame (5) of the machine. Between shafts (12 and 14) of the right and left wheels (6 and 7) of the machine is fixed by means of bearings (16) on frame (5) of the machine coaxially to shaft (14) of right wheel (7) intermediate shaft (17) connected through cardan shaft (18) with shaft (12) of left wheel (6) and connected to shaft (14) of right wheel (7) through friction coupling. One of half-couplings (19) of the friction coupling is connected by a fixed connection to intermediate shaft (17), and second half-coupling (20) is mounted on shaft (14) of right wheel (7) with possibility of axial movement and is connected to rod (22) of actuating hydraulic cylinder (23) fixed on frame (5) of machine parallel to axes of shafts (12 and 14) of wheels (6 and 7) of the machine. Rod cavity (A) of feed cylinder (9) is connected via hydraulic line (24) with piston cavity (B) of actuating hydraulic cylinder (23).

EFFECT: providing straightness of working stroke of trailed asymmetric machine without occurrence of power moment relative to point of coupling of machine with tractor, which negatively affects its controllability when performing straight working stroke.
