DEVICE FOR STABILIZATION OF STRAIGHT MOTION OF TRAILED ASYMMETRIC MACHINE Russian patent published in 2024 - IPC A01D75/28 

FIELD: machine building.

SUBSTANCE: invention relates to devices for stabilization of rectilinear motion of asymmetric trailed machines by balancing of deflecting moment arising from asymmetric part of trailed machine. Stabilization device comprises traction lever 1 having a rear part rigidly connected to the frame of the trailed asymmetric machine, and a front part connected to tractor 4 through a hinge fastener made in the form of a cross-shaped hinge equipped with a crosspiece. Crosspiece is formed by pivot 5 and horizontal axis 6, located mutually perpendicular to each other, wherein crosspiece pivot 5 is located vertically in the vertical longitudinal plane crossing the axes of the tractor running wheels 4, and is connected by fork-flange 7, which is rotary in the vertical transverse plane, with rear part of tractor 4, and horizontal axis 6 of crosspiece is connected to traction lever 1 by means of fork 8 rigidly fixed on front end of traction lever 1. Device for stabilization is equipped with hydraulic system with hydraulic fluid pressure source and two-position distributor with slide valve arranged on tractor 4, kinematically connected with tractor steering system 4. Pendulum lever 12 is fixed on the upper end of pivot 5, which is located in the side opposite to the asymmetric part of the trailed machine. Free end of pendulum lever 12 is connected with rod of hydraulic cylinder 13 of one-way action, controlled by slide valve of two-position distributor, through pin-slider 14 and link 15 fixed on rod of hydraulic cylinder 13. Hydraulic cylinder housing 13 is fixed on fork-flange 7 by means of hinge 16 located in front of pivot 5 along tractor 4. Slot of link 15 is made coaxially to hydraulic cylinder 13 with the possibility of movement of pin-slider 14 along this slot.

EFFECT: stabilization device provides stabilization of straight-line movement of trailed machine.
