The invention relates to the transport industry, in particular to systems that provide passive safety of passengers during rollover in the transverse plane of the vehicle (e.g., buses) due to the automatic triggering of the restraint means.

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 can be attributed to a 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, A.S. 816849, CL B62D 49/08), is that to prevent tipping of the 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, B60K 28/14, Beukelman, V.i.bogdanov. No. 2010106915/11; Appl. 24.02.2010; publ. 10.07.2011. Bull. No. 19. - 7 S.: ill.). This device is chosen for the prototype.

On the roof of the body of the vehicle (e.g. bus) the mouth is oflen antiproteinase node, associated with a sensor of angular position relative to 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 arm 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 transport wheels cf is DSTV.

The device prototype has a flaw: despite prevent overturning of the vehicle on the roof, at high initial velocity overturning at the time of contact of the stop with the supporting plane of the wheels is possible twisting of the vehicle relative to its longitudinal plane.

The objective of the invention is to develop a device that prevents twisting of the vehicle relative to its longitudinal plane when triggered antiproteinases site during tipping.

The problem is solved as follows. Device to prevent tipping of the vehicle contains the constant current source is a battery, the inverter angular position of the vehicle, consisting of two differentially connected by a spiral spring, 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 arm of a resistive bridge circuit, the conclusions of the measuring diagonal of the bridge circuit are connected to the inputs of the comparator, the comparator output is connected to the contactor, the contacts connect the battery to the actuator of the gas generator with a pneumatic cylinder having communication with the mechanical antiproteinase node containing the Shen, the nominating rod with integral spring clips and emphasis, characterized in that the emphasis, consisting of a frame associated with the outer side panel, the inner side of the rod through the bracket securing it contains stops, clamps and wheels, pivoted levers to the frame rest on the top of which the influence of the spring.

The technical result that can be obtained by carrying out the present invention is to expand the functionality by providing a stop antiproteinases node wheels. This prevents twisting of the vehicle relative to its longitudinal plane when triggered antiproteinases site during tipping, and, consequently, increases the passive safety of vehicles (e.g. buses).

Figure 1 and 2 shows the design emphasis antiproteinases host vehicle. The stop consists of a frame 1 to which are attached: on the one hand panel 2 and the rod 3 through the mounting bracket 10, the levers 7 with wheels 9, the spring 8, the tabs 5, the limiter 6. Wheels 9 are based on the roof of the body 4 of the vehicle.

When triggered antiproteinases node (3, 4) rod 3 begins to move and push the frame 1 stop, with all details included in its design At the time, when the wheels 9 will go beyond the body 4, the levers 7 under the action of the springs 8 will turn on its hinges 11 to the stop stop 6 and is locked in this position by clamps 5.

The rod 3 extends to its maximum length, the body 4 of the vehicle continues to change its position relative to the longitudinal axis to the contact of wheel 9 against the reference plane of the wheels of the vehicle (figure 5).

The proposed solution will provide the passive safety of the vehicle, the protection of life and health of the driver and passengers during a rollover of the vehicle in the transverse plane.

The retaining means of the passenger compartment of the vehicle containing the constant current source is a battery, the inverter angular position of the vehicle, consisting of two differentially connected by a spiral spring, 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 comparator, the comparator output is connected to the contactor, the contacts connect the battery to the actuator of the gas generator with a pneumatic cylinder having communication with the mechanical and tirocinium node, containing a piston pushing the rod with integral spring tabs and the stop, wherein the stop consisting of a skeleton associated with the outer side panel, the inner side with the rod through the bracket securing it contains stops, clamps and wheels, pivoted levers to the frame rest on the top of which the influence of the spring.
