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 actuation antiproteinases node.

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, A.S. 816849, CL B62D 49/8), in which to prevent tipping of the vehicle (e.g. 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, A.S. 2423280 C1, CL B62D 49/08, B60K 28/14). this device is chosen for the prototype.

On the roof of the body of the vehicle (e.g. bus) is 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 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 transport wheels is the means.

The device prototype has a drawback: the moment of contact of the stop with the supporting surface of the wheels of the vehicle is accompanied by the release of a large amount of impact energy that can lead to the destruction of parts antiproteinases node.

The objective of the invention is to develop a device for preventing rollover of a vehicle on the roof, the construction of which will reduce the probability of failure of parts antiproteinases node.

Device to prevent tipping of the vehicle contains the constant current source is a battery, the inverter angular position of the vehicle 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 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 site that contains a piston that attaches the rod with integral spring clips and emphasis differs the fact that vydvigayus the SJ stem with integral spring tabs affects emphasis, located in the middle part of the side surface of the body of the vehicle and pivotally connected with a rod attached to the upper portion of the side surface of the body of the vehicle.

The technical result that can be obtained by carrying out the present invention is to expand the functionality by providing a vehicle antiproteinase node and driven them rotating reference frame. This prevents tilting of the vehicle (e.g., buses) on the roof and increases its passive safety.

Figure 1 shows the layout of elements on the device to prevent tipping of the vehicle.

On the lateral surface 7 of the body of the vehicle (e.g. bus) installed antiproteinase the node associated with the angular position sensor 1 relative to the longitudinal axis (roll) body control unit 2. The control unit 2 connects the battery to the actuator of the gas generator 3 connected to the pneumatic cylinder 4, hinged to the sidewall of the body 7. The rod 5 of the cylinder 4 pivotally connected with the stop 6, fixed razminaem clamp 9 to the sidewall 7. To stop 6 hinged at one end also attached to the rod 8, the other end of the rod 8 is pivoted in the upper cha the ti side surface 7 of the body.

The work of the proposed device to prevent tipping of the vehicle is as follows (figure 2, figure 3).

During vehicle operation the current value of the roll angle of the body is determined by the angular position sensor (roll) 1. In that case, if the current value of the roll angle of the body will be equal to or exceed the low value of the critical value, the control unit 2 will connect the current source to the actuator of the gas generator 3. The actuator is activated, ignites the combustible material contained in the gas generator. The resulting gas is supplied to the pneumatic cylinder 4 and pushes the piston rod 5. The stem 5, extended, other side affects stop 6 and raises the rod 8. When reaching the piston rod 5 end position he still fixed by means of spring clamps in the cylinder 4.

The body of the vehicle continues to change its position relative to the longitudinal axis until it touches the stop 6 with the supporting surface of the wheels of the vehicle.

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.
