position, and the axis of rotation of the other flywheel deviates by an angle

 The problem to which the claimed invention is directed is to maintain the equilibrium of a two-wheeled single-track vehicle without the use of gyrostabilization mechanisms or changing the direction of movement by turning the steering wheel.

SUBSTITUTE SHEET (RULE 26) The problem is solved by controlling the position of the center of gravity (center of gravity) of the vehicle using a sliding axis, for which there is a wheel on the rear axis that can rotate on the axis and slide along the axis, while the loss of balance is controlled by an electronic tracking device, and restoration of equilibrium occurs by moving c.t. due to the sliding of the rear axle with the fork relative to the wheel using a screw, clamp or other drive mechanism, the power supply of which is carried out from the onboard or external

source, while to eliminate additional overturning moment, t.t. the vehicle is located in the plane (or as close to the plane as possible) of the action of the force that controls the sliding of the axis in the wheel.

 In addition, to increase the efficiency of maintaining equilibrium by increasing the displacement amplitude of the center gear, an increase in the amplitude of the axle slip in the rear wheel is used, for which the arm of the sliding control force should be as possible as possible, or the sliding axles in the rear and front wheels are used simultaneously.

 To move along a rectilinear narrow supporting surface, for example, along a rail, and to prevent slipping of the wheels, including the axis of which is sliding, the wheels are mounted on the rim

anti-slip side pads.

 The technical result achieved is to maintain the equilibrium of the two-wheeled single-track vehicle by controlling the position of the c.t. using a sliding axis, without using the gyrostabilization mechanism or changing the direction of movement by turning the steering wheel.

 The invention is illustrated by drawings, which do not cover and, moreover, do not limit the entire scope of the claims of this technical

SUBSTITUTE SHEET (RULE 26) decisions, but are only illustrative materials of a particular case of execution:

 Figure 1 is an isometric view of a two-wheeled single-track vehicle.

 Figure 2 is a rear view, a diagram of the acting forces.

 In Fig.Z a schematic top view of the arrangement of the axes and central heating

 In Fig.4, the drive mechanism of the sliding axis of the screw.

 In Fig. 5, the drive mechanism of the sliding axis is rattle.

 In Fig.6 anti-slip side pads on the wheel for driving on a rail.

 The method consists in the fact that to control the position of the center of gravity of the vehicle, a wheel 1 is located on the rear axle 3 (Fig. 1), which has the ability to rotate on the axis and slide along axis 3, while the loss of balance is controlled by an electronic tracking device 4, and restoration equilibrium is achieved by sliding the rear axle 3 with the fork 7 relative to the wheel 1 using a screw, cremallera or other drive mechanism with an engine 2, the power supply of which

carried out, for example, from an onboard source 5.

 To eliminate the additional overturning torque The vehicle is located in the plane S (Fig. 1) (or as close as possible to the plane S) of the action of the force P, which controls the sliding of the axis in the wheel.

 Using the sliding axis controlling the force axis P (FIG. 2), the axis of the vehicle with the fork moves relative to the wheel until a sufficient counter-throwing moment of the force G2 occurs, which compensates

the overturning moment of force G arising from the action of an external force F, and, exceeding it, returns the position of the center of gravity of the vehicle in

equilibrium state.

 In addition, in order to increase the effectiveness of maintaining

the equilibrium of the vehicle by increasing the amplitude In the movement of c.t. (Fig. 3), used:

SUBSTITUTE SHEET (RULE 26) a) an increase in the amplitude L2 of the axis movement in the rear wheel, for which the arm L1 of the action of the sliding force P must be

the maximum possible, that is, c. should be located as close as possible to the sliding rear axle and as far as possible from the front axle of the vehicle. b) the simultaneous use of sliding axles in the rear and front wheels, which, with the same amplitude of the L2 axis, allows the c.t. with increased amplitude C, while there are no requirements for size L1.

 The design of the screw drive mechanism of the sliding axis (Fig. 4) consists of a fork 7 mounted on bearings 4 of the axis 3 with a screw thread cut along the entire length along which a threaded nut 5 with a bearing 6 and wheel 1 mounted on it moves. For linear

moving the nut 5, the axis 3 rotates in the bearings of the axle bearings, receiving torque from the engine 2 through the drive gear 8. For

prevent rotation on the axis 3, nut 5 is made with an eccentricity of the outer diameter and inner hole.

 The design of the cremeler mechanism of the drive of the sliding axis (Fig. 5) consists of a fork 7, a fixed axis 3

of a rectangular profile on one face of which there is a gear rack 4. A nut 5 with a wheel 1 mounted on a bearing 6 is moved along the axis 3 on the support 8 and pressure rollers 9. From the engine 2, the torque is transmitted to the drive gear 10, which, being in

meshing with the rack, moves the nut 5 with the wheel 1 along the axis 3.

 To prevent the wheels of the vehicle from slipping under the action of a force P 1, the axis of which is sliding, with a rectilinear narrow support

surfaces, for example rail, are mounted on the wheel rim of the vehicle

anti-slip side pads (Fig.6).

 The method works as follows:

Under the influence of external force, the vehicle exits

vertical equilibrium state moves and arises

SUBSTITUTE SHEET (RULE 26) overturning moment. Using a drive mechanism, the axle of the vehicle with the fork slides relative to the wheel until a sufficient counter-tipping moment occurs, which compensates for the overturning moment, and, exceeding it, returns the position of the center of gravity of the vehicle to the equilibrium state, while the transverse force of the wheel

it is compensated by the friction force of the wheel and the bearing surface or by the reaction of the anti-slip side pads on the wheel rim (if the bearing surface is a rail).

 Monitoring the position of the vehicle and the resulting deviations implements an electronic tracking device, and the computer system controls the axis movement in the wheel. The axis drive mechanism itself can be screw, rack, or other, whose power is supplied from an onboard or external source.

 The use of sliding axles on the front wheel simultaneously with the rear wheel increases the efficiency of controlling the equilibrium of the vehicle, since with the initial deflection of the c.t., the movement of the sliding axles on both wheels gives a greater movement of the c.t. than using only the rear sliding axle.

 Thus, the claimed method allows the vehicle to maintain equilibrium even in a static position, as well as when driving along a narrow, straight support surface, for example, along a rail without using gyro stabilization mechanisms or changing the direction of movement by turning the steering wheel.
