When the car is tilted more than the set one way or the other, the central electrode is connected to the lower side ones, thereby providing light and sound alarms, which indicates to the driver about a dangerous situation from the point of view of the machine toppling over. With __ further inclination of the machine, approaching the maximum permissible, there is an electrical connection of the central electrode with the upper side, which leads to a voltage supply in. intermediate relay. An intermediate relay, when an electric current flows, activates and provides a power contact closure. In this case, an electric current passes through the solenoid and the cores are drawn in. The cores act on the two-arm levers and provide the brake pedal and clutch to move towards the brakes on and off the clutch .. As a result, the machine stops without driver intervention, which prevents it from tipping over and causing an accident.

Further movement of the machine for. emergency response is possible. only when the driver presses and holds the button of the switch 9 • in the off position.

It is possible to simplify the design of the device in question for those machines in which the brake pedals and the clutch are displaced with little effort, it is advisable to connect the upper side electrodes directly to the solenoid, bypassing the intermediate relay, which is not necessary in this case. In addition, the rods of the brake pedals and the clutch can be used as the core of the solenoid. In this case, there is no need to use two shoulders. Levers.

The implementation of a cylindrical glass sensor with an inner diameter of 4 mm (at the edges) with a gradual increase in diameter to 8 mm (in the middle part) in the form of a half ring makes it impossible to rupture the volume of mercury contained in it when the machine is moving on an uneven surface and the device is malfunctioning.

Claims (1)

The invention relates to a device that increases the safety of operating vehicles having a drive from an internal combustion engine. A device for preventing a vehicle tipping over is known, which contains an electric roll sensor in the form of a U-shaped tube partially filled with fluid that is electrically connected to an actuator in the form of a solenoid tl. However, the device prevents the vehicle from tipping over by acting on the engine's power supply system, and just by stopping it. Stopping the engine makes it difficult to eliminate the dangerous danger that precedes the rollover in vehicles with a stabilization system. When the engine is stopped, this system stops working, in addition, the driver is not warned by the sapaitee about the occurrence of dangerous situations and has no opportunity to correct the situation in a timely manner. All this reduces the safety of operation of the vehicle. The purpose of the invention is to increase the safety of vehicle operation. The goal is achieved by the fact that the sensor tube is partially filled with mercury and equipped with a central electrode installed in its knee and connected to a power source and side electrodes installed in its end parts, the side electrodes are located on two levels, the lower ones are electrically connected with sound and light sources, as well. The uppermost in series are connected solenoids, the cores of which are mechanically connected to the brake pedals and the vehicle clutch. The drawing shows the device, the overall appearance. The device consists of a sensor 1; signal lamp 2, sound signal 3, intermediate relay 4, solenoids 5, 6 double-arm levers 7 and 8, switch 9 and electrical wires .. Glass sensor 1 of cylindrical shape with internal diameter from 4 mm (edge) to 8 mm ( the middle part) is made in the form of a half ring filled with 1/3 of the volume of mercury, has a central electrode - and two side electrodes at both ends. The sensor is mounted on the vehicle in a vertical plane, as shown in the drawing. The bottom side electrodes are used to turn on and off the light and sound alarms, and the top ones to turn on and off the intermediate relay. The signal equipment 2 and the sound signal 3 can be used with standard equipment mounted on a vehicle. The intermediate relay 4, when switched on, ensures the closure of the power electrical contact, thereby ensuring the passage of electric current through the solenoids 5 and 6 having cores. The solenoid cores by means of two shoulders 7 and 8 are connected to the brake pedals and the clutch of the vehicle. In the control circuit of the intermediate relay, a switch 9 is installed, the normal position of which is permanently closed contacts. The sensor and all elements of the device are connected to the source of electrical energy of the machine as shown in the drawing. When the machine is moving, its engine is running and a given constant voltage is maintained in the electrical system. This voltage is applied to the central electrode of the sensor. If the machine moves along a horizontal soil surface, then the electrical connection between the central electrode and the side electrode does not occur and the device in question does not work. When the machine is tilted more than specified in one direction or another, an electrical one occurs, the central electrode is connected to the bottom side, thereby providing light and sound alarm, which indicates to the driver that a dangerous situation has arisen from the point of view of the machine tipping over. When the machine is tilted further, the shchemus is approaching the maximum allowable, the central electrode is connected electrically with the upper side electrode, which leads to voltage being applied to. intermediate relay. An intermediate relay during the flow of electric current activates and ensures the closure of the power contact. In this case, an electric current passes through the solenoids and the cores are drawn in. The cores act on two shoulders and provide movement of the brake pedal and clutch in the direction of engaging the brakes and disengaging the clutch. As a result, the machine stops without the driver, which prevents it from tipping over and causing an accident. Further, the movement of the machine dl. emergency response is possible only when you press and hold the switch button 9 in the off position by the driver. It is possible to simplify the design of the device in question for those machines in which the movement of the brake pedals and clutch occurs at low forces, it is advisable to connect the upper side electrodes directly to the solenoid, an intermediate relay, which is not necessary in this case. In addition, brake pedal pins and a clutch can be used as the core of the solenoid. In this case, there is no need to use double-arm levers. The implementation of a cylindrical glass sensor with an internal diameter of 4 mm (along the edges) with a gradual increase in diameter to 8 mm (in the middle part) in the form of a half ring makes it impossible to break the volume of mercury in it when the machine is moving on an uneven surface and a false positive. devices.
