    A. A device according to claim 3, characterized in that the pneumatic cavities of the hydro-pneumatic accumulators are connected via control valves with a pressure source of the vehicle's pneumatic braking system.
    Steered by steering wheel 18 and located on section 2 of a vehicle with a front axle controlled 19, steering gear 20 transfers gear moment 21 to a bipod 22. The last segment 23 is attached to which is pressed from a friction pad made of friction material 24 sec. limited by 5, on which the mounting screws 2 of the levers 27, which are mounted on the bolts 25, are made in the form of two-arm levers.
    To the opposite ends of the levers 27 are connected hydraulic pistons 28. Hydraulic lines 31 and 32 are connected to the liquid chamber 29 of the hydraulic cylinder 30 and connected to the valve assemblies 10.
    The spun assembly 10 consists of a lower fluid chamber 33 connected to pipeline 9, a check valve 34 embedded in a partition 35 separating two chambers, regulating throttles with locking elements 36 connected by lever mechanisms 37 to the 38J hydraulic cylinder, which are hydraulically connected to hydraulic lines 3 and 32.
    For information of the driver, pressure gauges 39 and control valves 40 are attached to the pneumatic chambers 14 of the hydroaccumulators 13.
    In the device according to the second variant (FIG. 4), the positions 1-17 are kept the same. The difference of the second variant from the first one is that the device has a comparison unit 41, which functionally interacts with the valve units 10.
    The front axle 42 of the vehicle section 2 is controlled by steering 43 via gear 44 to the bipod 45, whose angle of rotation is proportional to the steering angle of the front wheels. A sensitive element of the steering angle of the steerable wheels, made in the form of a master cylinder 4, is connected to the bipod 45.
    The piston 47 of the hydraulic cylinder 46 is pivotally connected to the bipod 45, and its hydraulic chamber 48 is connected by pipe 49 to the liquid chamber 50 of the hydraulic cylinder 51. The hydraulic piston 52 is spring-loaded 53 and connected to the input of the Comparison Unit A1. In addition, the piston 54 of the hydraulic cylinder 55 is connected to the inlet of the comparator block 41, the liquid chamber 56 of which is connected to the folding angle sensor of the sections in the form of a hydraulic cylinder 58, the housing 59 of which is attached to the vehicle section 2, and the piston 60 to the section 3 of a vehicle, with pipeline 57 connected to its liquid chamber 61.

     The comparator unit 41 may be made in the form of a mechanical lever design, the piston 52 and the piston 54 being installed in parallel but in the opposite direction, and the comparative arm 64 is attached to them by means of hinges 62 and 63. The levers 65 are kinematically connected with the comparison arm 64 and connected to the respective sub-base elements of adjustable chokes 66 located in the valve assemblies 10 in the corresponding partition 67, 8 of which is also fitted with an external kyapan 68.
    B system installed pressure gauges 69 and control valves 70.
    The device according to the first embodiment operates as follows.
    In the states of the steering mechanism 20, the hydraulic pistons 28 are in the middle position, respectively, the locking elements 36 are open, and between the working chamber 8 and the hydroaccumulator 13, the liquid can be pressed freely. I flow in both directions through the pipeline 9, the valve assembly 10 and the pipeline 11.

    If the folding angle between sections of the vehicle changes, then from the corresponding working chamber 8 the fluid flows into the hydroaccumulator 13 so that the gas pressure increases. At the same time, fluid flows from the accumulator 13 to another working chamber 8 so that the gas pressure in it decreases. The same pressure prevails in the working chambers as in the gas chambers 14 connected to them, because the force caused by the pressure difference creates around the hinge 4 a moment opposite to the direction of the break in the axis. The greater the angle of fracture of the axis, the greater the opposing moment is created by the hydraulic cylinders. In a straight-line motion of articulated vehicles, the described effect contributes to damping oscillations of the second section of the vehicle arising in the transverse direction.
    When rotating the steering gear, the device operates as follows. When the steering wheels turn to the right of the steering wheel, the bipod 22. rotates counterclockwise, together with the segment 23, the friction block 24 is displaced all the way, the lever 27 mixes, the hydraulic piston 28 locks the corresponding locking element 36 of the valve assembly 10. In accordance with this only from another accumulator 13 via pipeline 11, non-return valve 34 and pipeline 9 into working chamber 8, i.e. one of the hydraulic cylinders 7 can only work for stretching and is blocked against compression. The corresponding hydraulic cylinder 7, which admits an axial fracture, determined by turning the steering wheels to the right, expands, and in the event of an axial fracture in the opposite direction (ejection of the secondary vehicle from the turn), it is locked.
    Meanwhile, the flow of the hardening fluid passes unhindered in both directions between the working chamber 8 and the hydraulic accumulator 13.
    The device Yu according to the second embodiment operates as follows.
    In a straight-line movement of an articulated articulated train 1, the angles of rotation of the steered wheels and the folding are zero, and the comparative FL-40 64 is in the middle position.

    The throttle 66 of the valve assembly 10 Tbij hydraulic chambers 8 hydraulic cylinders are in communication with fluid {Chambers 12 hydraulic accumulators 13. The working fluid is under pressure from pneumatic chambers i4,
    If, with the steering angle of control of my wheels equal to zero, section 3 collapses, for example, in one and three directions s, then the folding angle hydraulic cylinder compresses 5 the liquid flows out. the hydraulic chamber 8 in the cylinder, cylinder 55, pushes the piston 54, as a result of which the comparative market 4-a.g 65 turns around the hinge 62
    The lever 63 rotates and displaces the suspendable element of the throttle 66 of the Yuz valve assembly, which is locked. Despite the contraction of the throttle body, liquid can flow from the working chamber 8 of the hydraulic cylinder 5. Through the pipeline 9 into the hydraulic circuit 2, you can go over the reinforced section. - Lekhzke, as a result of the working cylinder, 5 creates a cillet, which is the reserve of the spine 10 “When pushing out the other n sub-cylinder; Section 5, the fluid can flow uninterruptedly into the hydraulic chamber I from the hydraulic chamber 12 through the pipeline It through the valve unit 10, in which the movable element of the dross ™ l 65 opens unhindered and the check valve 68 also passes the fluid in this direction.

    When cornering an articulated vehicle with controlled steering of the front wheels, the device operates as follows.
    When the steering wheel rotates to the right, the piston 47 pushes the working fluid out of the hydraulic cylinder 46. At the same time, the fluid is fed through the pipe 49 into the liquid chamber 50 of the hydraulic cylinder 515, the piston of which moves by compressing the spring 53 and turning the lever 65.
    IF the vehicle is moving on a turn without skidding, then the angle of kink of the axis corresponds to the angle of rotation of the steered wheels, i.e. The hydraulic valve TS1SHINDR 58 is pushed apart, into the liquid chamber 61 through line 57 it receives the liquid of the hydraulic cylinder 55, so that the piston 54 rotates the lever 65. When the angles of the folding of the sections and the turning of the controlled wheels coincide with each other, the pistons 52 . and 54 are moving in such a way that the drive plate 65 does not act on the sub-elements of the throttles 66 and the valve assemblies 10 are open.
    If the folding angle of the sections differs from the angle of rotation of the steerable wheels, then the lever 65 closes the corresponding throttle 66 and one of the valve assemblies 10 will be covered to prevent improper misalignment of the corners.
