The invention relates to the transport industry, in particular to systems that provide directional stability of the vehicle (e.g., buses) against overturning in the transverse plane, by changing the position of its center of mass.

A known system of automatic stabilization of the vehicle (e.g. tractor), which is designed to maintain the vertical position of the skeleton of the vehicle. The stabilization system includes: a stabilizer pendulum, Executive cylinders with check valves, faucet off of the stabilization system, the flow divider and control devices. The units of the stabilization system are placed in different areas of transport and interconnected metal pipes and hoses (Xenetic I.P. and other Tractor MTZ-80, its modifications, M., Agromisa, 1991, s-268).

The disadvantages of the system of automatic stabilization include: large and weighs about 15 kg, the complexity of the maintenance associated with bulkiness and extra cylinders, oil piping, valve and other parts, each type of transport requires its own set of elements of the system of automatic stabilization.

It is known and the other device (SU, and. C. 816849, CL 62D 49/08), in which the exception is prokidyvaya vehicle (for example, wheeled tractor) contains a sensor of angular position filled with electrically conductive fluid (e.g., mercury) in the U-shaped tube with side electrodes connected to a power source (e.g. generator), the source of the sound and light signal. In addition, the device includes: an intermediate relay, electromagnetic Executive power elements (solenoids), the cores of which is mechanically connected with the pedal, clutch and brake by means of two shoulders of the levers. In the control circuit relay is installed the switch.

This device is not without flaws. The device used harmful substance - mercury; the larger the weight, exceeding 6 kg; a large number of used electrical appliances (for example, relays and the like); limited functionality due to the fact that this device works only when an unstable position of the vehicle in the longitudinal or in the transverse planes; each transport requires their devices and device elements.

A device to prevent tipping of the vehicle (EN, Pat. 2423280 C1, CL B62D 49/08, UK 28/14). The specified device is selected for the prototype.

On the roof of the body of the vehicle (e.g. bus) installed antiproteinase the node associated with the sensor of angular progenipoietin the longitudinal axis (roll) body control unit. The sensor is a transducer angular position of the vehicle and contains two differentially connected coil springs, the axis of which is fixed the upper end of the pendulum, its lower end is connected to the slider of the resistor with variable resistance of one of the shoulders of a resistive bridge circuit, the conclusions of the measuring diagonal of the bridge circuit are connected to the inputs of the control unit, consisting of a comparator, contactor and battery. The output of the comparator is connected to the contactor, the contacts connect the battery to the actuator with a gas generator connected to the pneumatic cylinder. The tilting of the vehicle body by an angle exceeding a critical value, the control unit connects with the power source, the actuator of the gas generator mounted on antiproteinase site. The actuator is activated to ignite the incendiary cannon charge, which ignites eject the charge generated gas enters the pneumatic cylinder and pushes the piston rod fixed on its end stop. The body of the vehicle continues to change its position relative to the longitudinal axis until it touches the stop with the supporting surface of the wheels of the vehicle.

This device has drawbacks: first, the device does not preclude tipping Tran is tailor tools, secondly, situated on the roof of the vehicle antiproteinase node increases the height of its center of mass.

The technical result that can be obtained by carrying out the present invention is to expand the functionality by providing a vehicle system improve the stability of the vehicle against tipping, due to the automatic actuation of the hydraulic system, shifting its center of mass in the direction opposite to the sudden roll of the body. This ensures stability against overturning in the transverse plane of the vehicle (e.g., buses).

Figure 1 shows the layout of elements of system of improvement of stability against overturning of the vehicle.

In the floor of the body 9 of the vehicle (e.g. bus) built through the spherical hinge of the pendulum 1, which holds the free oscillations of the spring 7. The pendulum 1 is vertical and has the ability to move when the tilt of the vehicle along the transverse vertical plane passing through the center of mass of the vehicle (bus).

The tilting of the vehicle body by an angle exceeding a critical value, the pendulum 1 is moved to fit the existing plane and in contact with one of the contacts 2 or 3, located on the left and right sides of the pendulum. Pins 2 and 3 are connected in parallel and in series with the power source 6, and with one of the contacts, electromagnets 4, 5. The electromagnets 4, 5 mounted on the panels 12, 13, attached to the floor of the body 9 of the hinge. The other contacts of the electromagnets 4, 5 connected by wires 11 from the power source 6. Between the floor of the body 9 and the panels 12, 13 are installed compressible vessels 14 filled with liquid. The vessel 14 is connected by a pipe with a hollow vessel. Receptacles installed above the floor of the body 9 of the vehicle and have the opportunity to expand in volume. Over the vessels above the floor of the body, a metal panel 15, 16, attached to the floor of the body 9 of the hinge.

Operation of the proposed system to improve stability against overturning of the vehicle is as follows (figure 2). When you change the current value of the roll body 8 (for example, towards the right side of the vehicle) to the critical values of the pendulum 1 interacts with the contact 2 connected in series electrical circuit with the electromagnet 4, and connects to the power source 6. When the electromagnet 4 forms a magnetic field is attracted to the metal floor of the body 9 and to the panel 16, displacing the liquid in the vessel 14. As a result, in the left part of the Tran is tailor tools focus vessels, filled with liquid, for a period of time of the magnetic field. In the right part at this point, the vessels are empty. This raises the additional weight of the fluid, shifting the center of mass 10 in the direction opposite to the roll body. As a result, the roll body is stabilized, the pendulum 1 ceases to communicate with the contact 2, the electromagnet 4 is de-energized, and the magnetic field disappears. The liquid from the top of the vessel by gravity into the lower vessel.

Similarly, the system improve the stability of the vehicle against tipping works if any body tilt towards the left side of the vehicle.

At higher speeds of vehicles are special requirements for reliability of the sensor of angular position of the body (roll).

In practice, there are many transducers and sensing elements with different physical nature (Handbook of means of automation / edited Weise and Eventica. - M.: Energoatomizdat, 1983. 504 S.).

The proposed technical solution, one element of a sensor of angular position of the vehicle body, as in the device of the prototype used a pendulum with a cargo mounted by means of a spherical joint. The pendulum is fixed the inner end of the flat spiral spring 7. The outer end ol the new well 7 is fixed to the vehicle body (the Reference means of automation / edited Weise and Eventica. - M.: Energoatomizdat, 1983. 504 C. Section 3, item 3.2., is. p.51).

Such design of the sensor of angular position of the vehicle in the transverse plane is not possible when driving on rough roads to freely oscillate to the critical values at which may arise false alarm control unit.

The proposed solution will provide stability against overturning of the vehicle.

System improve the stability of the vehicle against tipping, containing the constant current source is a battery, characterized in that the contacts of the contactor to connect the power source to the electromagnet, mounted on panel, hinged in the Central part under the floor of the body of the vehicle, putting pressure on the flexible container with liquid located between the panel and the bottom of the body and diagonally associated with hollow vessel mounted above the floor of the vehicle, closed top metal panel, hinged in the Central part of the floor body.
