Description

The utility model relates to transport engineering and can be used in wheeled vehicles, freight and special wheeled chassis.

A known system for regulating air pressure in tires, comprising a pressure-limiting valve, a control valve, a block of tire taps, heads for supplying air to the tire tires, shut-off air taps and pipelines [1].

The disadvantage of this design is the low pressure in the system, an open system for supplying air to the tires of all wheels, requiring long pipelines and elements of their connection and fastening, which reduces the tightness and reliability of the system as a whole. In addition, the block of mechanical cranes (according to the number of wheels) located on the instrument panel worsens the ergonomic properties of the cab and makes it difficult to use the system for multi-axle vehicles with a large number of wheels.

The closest technical solution, selected as a prototype, is a centralized system for regulating air pressure in tires, containing a pressure control valve with a pressure limiting valve, air supply heads to the tire wheels, tire valves for air lock, air pressure gauge and pipelines [2].

The disadvantage of this system is the inability to control the driver from the workplace by supplying air to the tire of a particular (damaged) wheel during movement due to the lack of control valves in the car cab. In this regard, it is necessary to stop the car, close the tire cocks of air constipation in order to inflate the damaged tire with air (with the exception of the pressure drop in the tires of other wheels), which significantly reduces the average speed of the vehicle, and in the conditions of warfare it significantly increases the likelihood of hitting a vehicle the enemy.

The technical result of the utility model is aimed at reducing the time to bring the system into working condition by providing the possibility of pumping a specific (damaged) tire of a multi-axis vehicle from the driver’s workplace in motion (without stopping the vehicle) by automating the process of restoring the required pressure in the tire if it is damaged.

The technical result is achieved by the fact that the system of regulating the air pressure in the tires, comprising a pressure control valve with a pressure limiting valve, air supply heads to the tire wheels, tire valves for air lock, air pressure gauge and pipelines, while the system is additionally equipped with an electromagnetic control unit valves with pressure drop sensors installed in the air supply pipes to the tires.

A distinctive feature of the prototype is that the system is additionally equipped with an electronic control unit for electromagnetic valves with pressure drop sensors installed in the pipelines for supplying air to the tires.

The figure shows a system for regulating tire pressure.

The system of regulating the air pressure in the tires includes a pressure control valve 1 with a pressure drop restriction valve connected through a tire pressure gauge 2 to an electronic control unit 3 of the electromagnetic valves 4, which receives signals from pneumatic pressure drops 5 installed in the pipelines for supplying air 6 to the pneumatic tires 7 through the air supply heads 8 and bus taps of air lock 9.

The system for regulating tire pressure is as follows.

Before starting the movement, the driver opens the tire taps of air lock 9 and turns on the electronic control unit 3, closing the electric circuit, as a result of which the electromagnetic valves 4 are closed.

In the event of a decrease in pressure in one of the tires 7, the pressure drop sensor 5 of the corresponding tire signals the driver through a change in the tire pressure gauge 2 and opens the electric circuit of the control unit 3, which gives the command to open the corresponding electromagnetic valve 4. The driver switches the pressure control valve 1 s pressure drop restriction valve to the “Air supply (pumping)” position. As a result, air flows through the air line into a particular damaged tire. At the same time, the driver, having information about the violation of the vehicle tire tightness, does not stop driving and is not distracted from the vehicle control process.

In this case, it eliminates the need to stop the car, the driver leaving the cab to close the tire taps of air lock 9 on damaged tires of the car.

Thus, the proposed design of the system for regulating the air pressure in the tires allows you to automate the process of restoring the required air pressure in the tires of the damaged wheels of the car, which can significantly improve the ergonomics of the car by installing electromagnetic valves in the system of the electronic control unit with pressure drop sensors installed in the air supply pipelines to the tires, and increase its mobility by eliminating the need to stop the machine.
