Description

The invention relates to vehicles, namely to gyro-stabilized two-wheeled single-track vehicles. The proposed gyro stabilizer of a two-wheeled single-track vehicle allows to improve handling, increase comfort and safety, and also indirectly contributes to the improvement of the road situation and the solution of parking problems.

Shilovsky’s two-wheeled automobile is known, the stability of which was ensured by means of a non-free (with two degrees of freedom) gyroscope, whose flywheel in the form of a disk was enclosed in a vertical cage (frame), which could be tilted forward and backward (see the article “The First Single-Lane”, publ. 02/22/2010 on the Internet at http://www.own.in.ua/view/item/1063; article "Shilovsky Petr Petrovich", published on 05/04/2012 on the Internet at http://www.vaostory.ru /blogs/o-chvom-malo-pishut/shilovskii-pyotr-petrovich.html). The lateral tilt of the frame was not required, since the speed of the device was small. A complex system of gyroscope deflection in the vertical plane of motion was made to compensate for the gyroscopic effect during ascents and descents. If the swivel passes through the center of gravity of the gyroscope, then this system is not needed at all. Obviously, it was necessary to rigidly fix the position of the axis of the gyroscope rotor when it was untwisted. Thus, the gyroscope did not allow lateral tilt at high speeds.

Closest to the proposed one is the gyrocar of the company Lit Motors (see the article "Gyrocar - in series ?: Hybrid", published in April 2012 on the Internet at http://www/popmech.ru/article/10761-girokar-v- seriju /; and also US 2011/0231060 A1, publ. 09/22/2011). The gyrostabilizer of this two-wheeled single-track vehicle includes at least two non-free (with two degrees of freedom) gyroscopes mounted longitudinally in a single frame. Each gyroscope has a rotor, the axis of which is pivotally connected to the ring, which is pivotally connected to the frame. The stability of this two-wheeled vehicle is ensured by the gyroscopic effect created by the rotation of these two proprietary gyroscopes in the frame. Vehicle speed, gyro rotor speed and front wheel deflection angle are controlled by electronic sensors. The disadvantage of this gyrocar is that for cornering at high speed, in order to ensure the frame tilts inward to turn, the electronics reduces the rotation speed of the gyroscope (gyroscopes), that is, reduces the stability of the vehicle.

The objective of the proposed invention is to eliminate these disadvantages.

The technical result of the invention is to enable emergency maneuver without reducing the speed of rotation of the gyroscope by simply tilting the driver’s body and the frame of the vehicle while simplifying the design by using only one gyroscope.

The technical result is achieved by the fact that the gyrostabilizer of a two-wheeled single-track vehicle is made in the form of a gyroscope in a cardan suspension, the outer ring of the cardan suspension has a two-way axial articulation with the frame of the vehicle, the axis of this connection being directed along the longitudinal axis of the vehicle, the inner ring of the cardan suspension has a two-way axial articulation to the outer ring, the gyro rotor shaft has a two-way axial articulation to the inside the steering ring of the gimbal, and the axes of all three joints are mutually perpendicular, the outer ring of the gimbal is a support for the driver, and the gyrostabilizer has a means of blocking the rotation of the outer ring about the axis of its hinge connection with the vehicle frame.

In the proposed technical solution, the disadvantages of the gyrocar are eliminated. The proposed gyrostabilizer has one gyroscope, and not two, as in the closest analogue. With the same total mass of rotors, the efficiency of one rotor is higher than two. The described vehicle has one free (with three degrees of freedom) gyroscope in a gimbal, and not two not free in a single frame, as in the closest analogue. Under any driving conditions, the gyro rotor speed does not need to be changed.

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

Driving a vehicle with the proposed gyro stabilizer coincides with driving a motorcycle or scooter. The driver performs an emergency maneuver at high speed by tilting his body and frame of the vehicle. The speed of maneuvering is significantly increased due to the use of the steps as a support for the gyrostabilizer.

The closest analogue is the gyrocar company Lit Motors - equipped with a complex system of electronic sensors. The proposed technical solution consists only of a gyroscope in a gimbal and a stopper mounted on the frame of the vehicle. Manageability and speed depend only on the skills of the driver, and reliability is ensured by the simplicity of design.

The invention is illustrated by drawings. Figure 1 shows a two-wheeled vehicle with the proposed gyro stabilizer side; figure 2 is the same from above; figure 3 is the same, in front, with the vertical position of the vehicle; figure 4 is the same, in front, with the inclined position of the vehicle; figure 5 - the proposed gyrostabilizer in isometry.

The gyrostabilizer is made in the form of a gyroscope 2 in a gimbal. The rotor shaft of the gyroscope 2 is oriented primarily vertically so that the gyroscopic effect does not affect the horizontal movement of the vehicle. The outer ring 3 of the gimbal is a support, in particular, a step 1 can be fixed on it as a support for the driver’s legs. In another embodiment, the footboard may be absent, and the outer ring may have an expanded upper part for the legs of the driver. The outer ring 3 has a horizontal bilateral articulation 4 with the frame 5 of the vehicle in the vertical plane of the frame 5. The outer ring 3 of the cardan suspension is oriented horizontally. The outer ring 3 has freedom of movement around the axis of the joint 4 directed along the longitudinal axis of the vehicle.

The inner ring 6 is oriented vertically and has a two-sided axial articulation 7 with the outer ring 3 at right angles to the plane of the frame 5. Swivel 7 of the rings of the cardan suspension allows the inner ring 6 to rotate or oscillate around an axis perpendicular to the axis of the swivel 4 of the frame 5 s outer ring 3 cardan suspension. The rotor shaft of the gyroscope 2 has a swivel joint 8 with the inner ring 6 of the cardan suspension, the axis of which is perpendicular to the axis of the swivel joint 7 of the suspension rings.

The frame 5 has a stopper 9, which allows to fix the outer ring 3 of the cardan suspension from rotation around the axis of its articulation with the frame 5 of the vehicle. The stop 9 is made in the form of a lever pivotally mounted on the frame 5; one of the positions of the lever blocks the rotation of the outer ring 3 of the gimbal suspension through the articulation 4 with the frame 5.

As you know, the lateral stability when driving two-wheeled single-track vehicles (motorcycle, moped) is provided by the gyroscopic effect of the rotation of the wheels. Turning at high speed is performed by tilting the vehicle into the corner. At low speed and with short stops, the gyroscopic effect is reduced, and the driver ensures the stability of the vehicle, resting one or two feet on the road surface. This fact does not allow to equip the vehicle with a closed cabin, which limits the use of the vehicle in adverse weather conditions. In addition, storing unprotected cabs outdoors makes them vulnerable to rain or vandalism.

The proposed technical solution allows to eliminate these disadvantages.

When rotating, the rotor of the gyroscope 2 creates a gyroscopic effect in the plane of rotation. The gyroscopic effect is transmitted through the inner ring 6 and the hinge joint to the outer ring 3 of the cardan suspension with the footboard fixed on it 1. The hinged connection 4 of the frame 5 with the outer ring 3 of the cardan suspension provides free rotation around the axis of the hinge, therefore, the gyroscopic effect does not extend to the frame 5 will be.

Driving a two-wheeled single-track vehicle with a gyro stabilizer involves two operating modes:

- with an outer ring 3 cardan suspension locked at a right angle relative to the plane of the frame 5:

- with unclosed outer ring 3 cardan suspension.

When the outer ring 3 of the cardan suspension is not locked, the gyrostabilizer does not exert a gyroscopic effect on the vehicle frame 5. Turning at high speed can be carried out by analogy with a motorcycle by tilting the frame 5 in the direction of rotation without the participation of the steering wheel.

When the outer ring 3 of the cardan suspension is not locked at low speed, the driver ensures the stability of the vehicle by changing the position of the steering wheel, and, resting its feet on the gyrostabilized footrest 1, can adjust the tilt of the frame 5 with the body.

With the locked outer ring 3 of the gimbal, the gyroscopic effect will be extended to the entire structure. At low speed, this mode allows steering. During short stops, this mode ensures the stability of the vehicle if the lateral force applied to the structure is less than the gyroscopic effect.

In any control mode, the gyro stabilizer does not affect the front or rear tilt of the vehicle. On descents and ascents, the swivel joint 7 of the inner 6 and outer 3 rings of the cardan suspension ensures that the orientation of the gyroscope 2 is maintained. The gyroscopic effect will not affect the tilt position of the frame 5 back and forth.

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

The gyro stabilizer allows you to control at high speed a two-wheeled single-track vehicle, like a regular motorcycle or moped. At low speed and during short stops, the gyro stabilizer provides the vehicle with stability, in which the driver does not need to lean with one or two feet on the road surface.

This technical solution allows you to equip a two-wheeled vehicle with a closed cabin, which, in turn, increases comfort and safety and turns a motorcycle or moped into a gyro.
