    Selection refers to vehicle engineering, in particular to tractors driven by wheel slip.
    A tractor driven by wheel slip, comprising a carrier frame with a driver cab, a drive unit and transmission wheels, is known.
    Tractors controlled by slipping wheels of known types, as a rule, are equipped on each side only with a pair of wheels, and these wheels do not have spring systems at all, therefore individual wheels in the vertical direction are not allowed to move individually. This leads to the fact that all the irregularities of the road are transmitted to the body of the tractor.
    The arrangement of the wheels on each side as close as possible to each other to reduce the impact of the reaction force, which always acts on the wheels of the tractor, controlled by the wheel spin, does not lead to the desired result when making a turn. The tractor is unstable and subject to oscillations. When moving - a scientific research institute of such a tractor on uneven ground, it is acted upon by forces causing strong vibrations, while the front and rear wheels alternately detach from the surface. If the oscillations become excessively intense, there is a danger of the tractor tipping over.
    In addition, when the tractor is subjected to such a swing, it is practically uncontrollable. The only way to suppress such wobbles is to completely stop the tractor. Such a tractor can move along roads at very low speeds.
    The purpose of the invention is to increase the stability when cornering. The goal is achieved with the fact that in a tractor driven by wheel slip, containing a carrier frame with driver cab, drive unit and spindle wheels, drive wheels, two on each side, are suspended longitudinally on longitudinal carts connected by a hinged average hour:
    with a tractor frame, and the tractor is equipped with additional wheels, located at least one additional wheel on each side, which are mounted on

    a rotary axis connected pivotally by the middle part with the possibility of swinging in a vertical plane with an additional frame connected at one end with the frame of the tractor, and the free end of the additional frame is equipped with a device for fastening to it trailed working implements.
    Quick couplings can be installed at the ends of the tractor frame to attach an additional frame.
    In addition, a trolley with two longitudinal wheels is suspended at the ends of the transverse axis. At the same time wheels can be both not driving, and so driving.
    The longitudinal carriages are installed with the possibility of raising and lowering their front ends to different angular positions by means of hydraulic cylinders around the transverse axis. Moreover, the additional frame is equipped with a hinge, which provides the possibility of its deviation in the vertical direction relative to the tractor frame, as well as a horizontal hydraulic cylinder, located between the additional frame and the tractor frame, forming a parallelogram mechanism with the additional frame.
    The tractor can also be equipped with two tracks, covering its wheels. In this case, the tractor is equipped with a hydraulic drive that contains adjustable hydraulic pumps and hydraulic motors that rotate the driving wheels.
    Such a tractor is very stable without a tendency to swaying; it has a relatively good spring effect, since both the longitudinal carriages and the vertical pivot axle sufficiently absorb the effects of road roughness.
    Fig. 1 shows a tractor driven by wheel slip, side view; figure 2 is the same, front view; Fig. 3 shows a tractor (option), side view.
    The tractor driven by the wheel slip contains the carrier frame 1 of the carriage on which the driver's cabin 2 is installed, the drive unit with the drive wheels 3. The drive unit contains mainly a diesel engine that drives two adjustable hydraulic pumps, or one
    5I
    or two electro generator Gilrop-COCI.I or electric generators are designed to transmit power to the hydraulic or electric motors of the tractor, and the motors are installed in such a way that they drive the corresponding wheels or groups of wheels. T Gach is equipped with one motor per cart or one motor per wheel 3, depending on the drive power or the required drive power of wheel 3. On each side of the tractor there are two drive wheels 3 and wheel 4 suspended on a longitudinal cart 5 on each side . The wheels 4 are suspended at the respective 1 and the same ends of the same transverse axis 6, the transverse axis 6 in its middle part is pivotally connected with the possibility of free vertical rotation with an additional frame 7, which is rigidly fixed at one end of the frame 1 of the tractor. At the free end of the additional frame 7 there are devices 8 for fastening trailed working tools of various types, for example, agricultural, excavator, towing, front loading, etc.
    Tractor driven by the wheel slip works as follows.
    The drive wheels 3 on one side of the tractor rotate at a higher or lower speed than wheels 3 located on the other side, depending on the direction of rotation of the tractor. The maneuvering is carried out with the help of a T-shaped control lever, which acts, for example, on two hydraulic pumps, and they supply fluid in one direction when the control lever moves forward and opposite to the direction of the direction when the lever moves backwards. The magnitude of the fluid flow depends on the degree of displacement of the lever from the initial position in a given direction. By turning the control lever around its longitudinal axis, the flow from the two pumps in opposite directions can be varied. Here, the number of revolutions of the hydromotors, and hence the wheels 3, varies in proportion to the above-mentioned volumetric flow rates.
    On the frame 1 of the tractor there are installed quick-release joints 9, which

    Allow to fasten an additional clamp 7 on the front or the rear end of the tractor.
    The use of such a device makes it possible to expand the possibilities of using the tractor, since the stabilizing additional frame 7 can be fixed to the end of the tractor on which increased stability is required. In addition, it is possible to distribute the load on the tractor in various ways.
    To increase the carrying capacity of the tractor, as well as reduce its wheels at the ends of the transverse axis 6, the longitudinal carriage 10 can be suspended, with four wheels 3,4 on each side of the tractor.
    Depending on the specific conditions of the wheel 4, which are directly or through the auxiliary elements attached to the ends of the transverse axis 6, can be leading or free. In particular, if the wheels 4 are also suspended on the carriage 10, then all the wheels of the tractor will be driving, which also increases its cross-country ability in difficult road conditions.
    Hydraulic cylinders 11 are located between the frame 1 of the tractor and, for example, the front end of the longitudinal carriage 5, which allow the carriage to be installed in different angular positions and fasten it around the transverse axis 12. If the hydraulic cylinders 11 are not locked, they have a spring effect . With the help of these hydraulic cylinders 11, much greater stability and better controllability of the tractor is ensured. If a tractor, for example, with a working tool attached to the rear, leaves the field, then both hydraulic cylinders 11 are first turned on so that the front ends of two longitudinal carriages 5 rise. At the same time, the rear wheels of each carriage are simultaneously pressed down so that the weight of the tractor concentrates on these wheels, ensuring that the tractor turns. In this way, it is possible to turn the tractor almost nl the master forcing said dvl wheels to rotate at different speeds in opposite directions.
    The cylinders 11 can also be used to provide a predetermined mass distribution when working.
    It is determined, chenn1 1m working tool, close to 111m per tonne. 0m- de.m1, yys hydraulic cylinders 1-1 can also be used for maneuvering, when the tractor is connected to the working tool.
    To improve the driveability of the tractor, the tractor may have a hinge 13 on the additional frame 7, which rotates the additional frame 7 in the vertical direction relative to the frame 1 of the tractor. In this case, a horizontal hydraulic cylinder 14 is installed between frames 1 and 7 and provides a hlrlogram connection. In the free position, the hydraulic cylinder 14 plays the role of a spring compensator when the hinge 13 is rotated, and when the hydraulic cylinder 14 is turned on, the frame 7 can be fixed in different angular positions relative to the frame 1.
    When used as a pusher or for working on a peat, it can be equipped with tracks 15 that cover all wheels 3 and 4 on each side (in Fig. 2, dashed lines show how the tractor can be equipped with wheels of different sizes and tracks).
    The application of the invention allows the tractor to be driven at equally high speeds both forward and backward. To facilitate maneuvering in such conditions, the tractor is equipped with a driver's seat, which can be rotated around a vertical axis and with which a control p1.1 tractor leg is connected. Such a construction facilitates the work of the candel when plowing, etc., since the driver can observe the space in front and behind.
    The transverse axis 6 has the shape of an inverted V, while the axis 6 of the ball is fastened in a rotatable manner to the additional frame 7 by means of an axis passing through the top V in the longitudinal direction of the tractor.
