The invention relates to vehicles, namely gyro-stabilized two-wheeled single-track vehicles. Proposed gyrostabilizer two-wheeled single-track vehicle can improve manageability, increase comfort and safety, but also indirectly contributes to the improvement of traffic conditions and solving problems with Parking.

Known two-wheeled vehicle Shilovsky, the sustainability of which was provided via a proprietary (with two degrees of freedom) of the gyroscope flywheel of which is in the form of a disk was enclosed in vertical clip (frame) that could bend forward and backward (see "First single", publ. 22.02.2010 on the Internet at the address http://www.own.in.ua/view/item/1063; article "Shilovsky Peter", publ. 04.05.2012 on the Internet at the address http://www.vaostory.ru/blogs/o-chvom-malo-pishut/shilovskii-pyotr-petrovich.html). Lateral tilt of the frame is not required, as the speed of the machine was small. A complex system deviation of the gyroscope in a vertical plane motion was made to compensate for the gyroscopic effect when the climbs and descents. If the pivot joint passes through the center of gravity of the gyroscope, this system is not needed. Obviously, it was necessary to rigidly fix the position of the rotor axis of the gyroscope when it is unwinding. Thus, the gyro is not �osmolal to lateral tilt of the implement at high speeds.

Closest to the proposed is gyrocar company Lit motors (see article "Gyrocar in the series?: Hybrid", publ. in April 2012 on the Internet at the address http://www/popmech.ru/article/10761-girokar-v-seriju/; and US 2011/0231060 A1, publ. 22.09.2011). Gyrostabilizer this two-wheeled single-track vehicle includes at least two longitudinally mounted in a single frame nonfree (with two degrees of freedom) gyroscopes. Each gyroscope has a rotor, the axis of which is pivotally connected with the ring, which is pivotally connected to the frame. The stability of this two-wheeled vehicle is provided by the gyroscopic effect created by the rotation of these two proprietary gyroscopes in the frame. The vehicle speed, the rotational speed of the rotors of the gyroscopes and the deflection angle of the front wheels are controlled by electronic sensors. The disadvantage of this gyrocar is that for cornering at high speed to provide a tilt frame inside of the turn, the electronics can reduce the speed of rotation of the gyroscope (gyro), that is, reduces the stability of the vehicle.

The object of the proposed invention is to remedy these disadvantages.

The technical result of the invention is to provide the possibility of an emergency maneuver without reducing the speed of rotation Hiroko�and a simple tilt of the housing of the driver and vehicle frame while simplifying the design by using only one gyro.

The technical result is achieved in that gyrostabilizer two-wheeled single-track vehicle made in the form of a gyroscope in the gimbals, the outer ring Kardanova suspension has a double-sided axial pivot joint to the frame of the vehicle, wherein the axis of this connection is directed along the longitudinal axis of the vehicle, the inner ring Kardanova suspension has a double-sided axial hinge connection with the outer ring, the rotor shaft of the gyroscope has a double-sided axial swivel with inner ring Kardanova gimbal, the axes of all three hinge joints are mutually perpendicular, the outer ring Kardanova suspension is a pillar for the driver but gyrostabilizer has a means of locking the rotation of the outer ring around the axis of its hinged connection with the frame of the vehicle.

In the proposed technical solution addressed the shortcomings of giocare. Proposed gyrostabilizer has one car and not two, as in the nearest analogue. When the same total mass of the rotors, the efficiency of the rotor is higher than two. Described the vehicle has one free (with three degrees of freedom) the gyroscope in the gimbals, not two proprietary to a single frame, as in the nearest analogue. While all driving modes frequency in�of ashenia of the gyro rotor is not necessary to change.

The closest analogue - gyrocar company Lit motors is controlled like a car. For carrying out, for example, an emergency maneuver electronics must first change the speed of rotation of one of the gyroscopes.

Driving a vehicle with the proposed gyrostabilizer coincides with the motorcycle or scooter. Make an emergency maneuver at high speed, the driver holds the tilt of his body and vehicle frame. Speed maneuvering is significantly increased through the use of footrests to support gyrostabilizer.

The closest analogue - gyrocar company Lit motors equipped with a sophisticated system of electronic sensors. The proposed technical solution consists only of the gyroscope in the gimbals, and a stopper mounted on the frame of the vehicle. The handling and performance depend only on the skills of the driver, and the reliability is simplicity of design.

The invention is illustrated in the drawings. Fig.1 shows a two-wheeled vehicle with the proposed gyrostabilizer side view; Fig.2 - the same, from above; Fig.3 - the same, front, the vertical position of the vehicle; Fig.4 - the same, front, when the inclined position of the vehicle; Fig.5 - proposed gyrostabilizer isometric.

Girot�beliator made in the form of gyro 2 in the gimbals. The shaft of the gyro rotor 2 is oriented mainly vertically to the gyroscopic effect does not affect the horizontal movement of the vehicle. The outer ring 3 Kardanova suspension is supporting, in particular, it can be fixed footrest 1 footrest of the driver. In another embodiment, the footrest may be absent, and the outer ring may have an extended top portion for the driver's feet. The outer ring 3 has a bilateral horizontal swivel 4 to the frame 5 of the vehicle in the vertical plane of the frame 5. The outer ring 3 Kardanova suspension oriented horizontally. The outer ring 3 has freedom of movement around the axis of the swivel 4 is directed along the longitudinal axis of the vehicle.

The inner ring 6 is vertically oriented and has a double-sided axial pivot joint 7 with the outer ring 3 at right angles to the plane of the frame 5. Swivel 7 rings Kardanova suspension allows the inner ring 6 to make rotational or oscillatory motion around the axis perpendicular to the swivel axis 4 of the frame 5 with the outer ring 3 Kardanova suspension. The rotor shaft of the gyro has 2 swivel 8 with the inner ring 6 Kardanova suspension, the axis of which is perpendicular to the swivel axis 7 rings on�weight.

The frame 5 has a stopper 9, which fix the outer ring 3 Kardanova suspension from the rotation around the axis of its hinged connection with the frame 5 of the vehicle. The stopper 9 is in the form of a lever pivotally mounted on the frame 5; a provision of the lever locks the rotation of the outer ring 3 Kardanova suspension on swivel 4 to the frame 5.

As is known, the lateral stability of two-wheeled single-track vehicle (motorcycle, moped) is provided by the gyroscopic effect of the rotation of the wheels. Cornering at high speed is produced by the tilt of the vehicle into the turn. At low speed and during short stops the gyroscopic effect is reduced and the driver insures a vehicle stability, based on one or two feet on the road surface. This circumstance does not allow to equip the vehicle with a closed cabin, which limits the use of the vehicle in adverse weather conditions. In addition, unprotected storage cabin vehicles under the open sky makes them vulnerable to the effects of rain and vandals.

The proposed technical solution allows to eliminate these shortcomings.

During rotation of the rotor of the gyroscope 2 creates a gyroscopic effect in the plane rotations�of. The gyroscopic effect through the inner ring 6 and the pivot joint is transmitted to the outer ring 3 Kardanova suspension with a fixed footrest 1. Swivel 4 frame 5 with the outer ring 3 Kardanova suspension provides free rotation around the axis of the hinge, therefore, on the frame 5 the gyroscopic effect will not apply.

Control of two-wheeled single-track vehicle with a gyrostabilizer involves two modes of operation:

- stalled at a right angle relative to the plane of the frame 5 of the outer ring 3 Kardanova suspension:

- with nezashorennym outer ring 3 Kardanova suspension.

When nezadovoljnom the outer ring 3 Kardanova suspension gyrostabilizer does not render on a frame 5 of the vehicle gyroscopic effect. Cornering at high speed can be carried out by analogy with the bike by tilting the frame 5 in the direction of rotation without the participation of the steering wheel.

When nezadovoljnom the outer ring 3 Kardanova suspension at low speed, the driver ensures the stability of the vehicle by changing the position of the steering wheel, and, resting his feet on a gyrostabilized bandwagon 1, can the housing to adjust the tilt of the frame 5.

When stalled the outer ring 3 Kardanova suspension gyroscopic effect will be distributed on sun� design. At low speed this mode allows control of the wheel. During short stops this mode ensures the stability of the vehicle when applied to the design lateral force will be less gyroscopic effect.

In any control mode gyrostabilizer does not affect the anterior or posterior tilt of the vehicle. On the descents and climbs swivel 6 7 internal and 3 external rings Kardanova suspension ensures the preservation of the orientation of the gyroscope 2. The gyroscopic effect will have no impact on the position of the tilt frame 5 back and forth.

The stability of the vehicle at low speed and with short stops provided by the gyrostabilizer, allows to equip the vehicle closed cabin. This, in turn, will protect the rider from adverse weather conditions, will increase comfort and safety and will ensure the safety of the vehicle in Parking lots.

Gyrostabilizer allows you to operate at a high speed two-wheeled single-track vehicle like a traditional motorcycle or scooter. At low speed and with short stops gyrostabilizer ensures vehicle stability, in which the driver does not need to rely on one or two legs on the road surface.

This technical solution allows you to use your�em to equip a two-wheeled vehicle enclosed cab, that, in turn, increases comfort and safety and makes the motorcycle or moped in siremobil.
