The invention relates to tractor and agricultural machinery, in particular to designs of tractors with a high degree of stabilization of the direction of movement.

The purpose of the invention is to improve the stability of the movement and performance.

FIG. 1 shows a schematic diagram of the construction of the unit; in fig. 2 - assembled machine-tractor unit, general view; in fig. 3 - hard rollers; in fig. 4 - connection of the propeller with a stabilizing wheel; in fig. 5 - intermediate bracket structures.

The unit contains stabilizing wheels 1 and 2 (Fig. 1) connected by bracket 3 (Fig. 4) to axles 4 and 5 (Fig. 1) of propulsion 6 and 7. Gears 8 and 9 are connected to axes 4 and 5 Fig. 1), which the intermediate gears 10 and 11 are engaged with gears 12 and 13. Gears 12 and 13 are fixed on the axles 14 and 15 of the stabilizing wheels 1 and 2. On the ends of the axes 14 and 15 are fitted intermediate brackets 16 and, 17 (Fig. 5), which are made with a bent finger 18. On a bent finger 18 (Fig. 1), a lever 19 is mounted, on the outer ends of which brackets 20 and 21 are fixed, soy e Inonii with rod 22 of hydraulic cylinder 23 and a spring-loaded piston rod 24 of the hydraulic cylinder 25, a spring-loaded.

The inner ends of the lever 19 are connected by a roller 26 (Fig. 3) and a groove 27 to the sleeve 28. A sleeve 28 (Fig. 3) is mounted on the rod 29 (Fig. 1) of the additional hydraulic cylinder 30, the body of which 31 is connected to the hitch arms 32 ( Fig. 2) by means of a cross-piece 33 (Fig. 1). The bottom 34 and the top 35 stops are made on the rod 29 and the piston 36 is mounted on the end of the rod 29. Through holes 37 and 38 are made on the body 31 of the hydraulic cylinder 30. Gear axles 39 and 40 are mounted on semi-axes x 4 and 5, the shaft of which 41 to 42 connected by braces 43 and 44 with weights 45 and 46. The ends of the levers 47 and 48 are fixed on the sleeves 49 and 50. On the sleeves 49 and 50 are fixed levers 51 and 52, the upper end of which is connected to the compression springs 53 and 54. The inner end 55 of the springs 53 and 54 is fixed on the connecting link 56. The link 56 of the frame 57 is connected with the rods 58 and 59 of the spools 60 and 6 1. On the rods 58 and 59 spools 60 and 61 are located pistons 62-65. The openings 66 to 69 of the spools 60 and 61 are connected via hydraulic lines 70 n 71, tees 72 and 73 to the drain and pressure lines of the tractor or gacha. Inside the hydraulic cylinders 23 and 25 are installed spring-loaded springs 74 and 75 of the hole holes 76 and 77, which are rods 78 and 79

connected to the brackets 80 and 81, respectively. The rods 22 and 24 of the hydraulic cylinders 23 and 25 are made with an integral design. The bore 82 is connected via the through holes 37 and 38 to the bore 83, and the openings 84 and 85 are connected to the openings 86 and 87 of the spools 61 and 60, respectively. Axles 4 and 5 are connected by means of a differential mechanism 88.

The proposed arperat works as follows.

In the absence of skidding, the propellers 6 and 7 of the beads, the loads 45 and 46 rotate with the same frequency and the openings 84 and 85 of the hydraulic cylinders 23 and 25 are closed (Fig. 1). At the time of the occurrence of the mismatch in rotational frequency between the engines 6 and 7 of the beads, the weights 45 and 46, by means of the gear reducers 39 and 40, acquire a different speed of rotation. Thus, when the left-side propulsion device 7 is pulling, the semi-axis 4 via the gear reducer 39 informs the shaft 42 a greater number of revolutions than the shaft 41 connected by the gearbox 40 with the semi-axis 5 of the right propulsion 6. At the same time, the loads 45, mounted on braces 43, move the sleeve 47 with the levers 49 left. Linked to the sleeve 49, the lever 51 releases the spring 53, which moves the link 56 to the left. Together with link 56, frame 57 and associated rods 58 and 59 of spools 50 and 51 move with it. As a result of these movements, the working fluid from the hydraulic system through tee 72, holes 66 and 86 and hole 84 enters the piston chamber of the hydraulic cylinder 23, and holes 85, 87, 68 and tee 73 enters the drain cavity of the hydraulic system of the tractor. In doing so, the rod 22 of the hydraulic cylinder 23 moves relative to the piston 76, compresses the spring 74 and displaces the working fluid from the piston cavity of the hydraulic cylinder 23 through the opening 82, through holes 37 and 38, the opening 83 into the free volume of the piston cylinder 25 of the right-side cylinder. In this case, the rod 22 and the body of the hydraulic cylinder 23 are mixed down, act on the bracket 20 and rotate the lever 19 around the finger 18. At the same time, the roller 26, rolling over the slot 27 of the sleeve 28 (FIG. 3), abuts against the upper abutment 35 (FIG. . one). The rod 29 with the piston 36 of the hydraulic cylinder 30 acts on the working fluid, which abuts the body 31 in the thrust 32 (Fig. 2) by means of the cross member 33 (Fig. 1). Then, the axis 15 by the intermediate bracket 16 (Fig. 5) presses the stabilizing wheel 1 against the ground, and the gear wheel 12, rolling around relative to the intermediate gear 10, receives a torque from the gear wheel 8 in the new position.
