-1- TARIFF PROPORTIONAL AS FEEDBACK FOR AIR SUSPENSION ION CONTROL. PNEUMATIC VALVE EXHAUST PORT USAGE Technical Area The present invention concerns air suspension control in heavy vehicles and trucks. It is related to systems. The invention specifically applies to proportional pneumatic feedback for air suspension control. The valve is related to exhaust port usage. State of the Art The main reason for using a proportional valve is to exceed the legally defined axle weight limit of 15. to maintain the pressure on the last non-driven single-tire rear axle of the 6x2 vehicle The goal is to reduce them proportionally. The driven axle (double tire) and rear axle (single tire) are the same. It has a pneumatic control source. Therefore, the pressure on the rear axle is proportionally distributed. should be reduced. On the other hand, this proportional valve also reduces the system pressure along the path. This causes a reduction in the speed bump (difficult road test). This is air 20 This will lead to a loss of pressure in the suspension system and cause the truck to drive at chassis level. This will cause it to fall during the process. The vehicle's ground clearance will decrease, and especially Uneven and potholed roads would present a potential ground contact issue. The known application is an electronically controlled valve and 25 for a single-wheel, non-driven rear axle. It is controlled by software using a pressure sensor. However, this increases the cost of the vehicle and... This increases the number of parts used in the vehicle. New technical developments are needed for this. Studies are being conducted on this. In application number CN105459753, the electronically controlled air suspension spring stiffness is 30. The adjustment mechanism is explained. Electronically controlled air suspension spring stiffness adjustment. Its structure is characterized by incorporating an air spring stiffness control device. However, air -2- New technical developments are needed that do not lead to pressure loss in the suspension system. It is heard. In this respect, a different technique has been explained. In conclusion, problems that lead to pressure loss in the air suspension system New technical developments to overcome this are becoming necessary. 5 Explanation of the Purposes of the Discovery Based on the current state of the art, the aim of the invention is to improve existing structures. The problems have been resolved, and for heavy vehicles, the air suspension control is back to 10. The notification concerns the development of a proportional pneumatic valve exhaust port system. Another purpose of the invention is to connect the proportional valve exhaust port to the main pneumatic line, Thus the system will be closed-loop and will not allow uncontrolled air pressure loss. It is not given. A new technique that works as closed-loop power supply control 15 It is the development of. Another objective of the invention is to enable the main control valve to adjust the height required for the defined vehicle height. It is adjusted to the pressure level. Adjustment according to the load in the vehicle's static state. is provided. 20 Another purpose of the invention is to allow the proportional valve's exhaust port to direct the necessary air to the rear axle. It expels air to distribute the pressure. This air loss leads to a loss of pressure during driving and This problem can be overcome because it will cause the vehicle height to decrease. Entry is ensured. 25 Another purpose of the invention is for the feedback loop to compensate for bumpy road conditions. and it prevents air from escaping. Main line pressure main control valve. Since it will be managed by [the relevant authority], the static condition will not be affected. -3- To achieve the aforementioned goals, the known aspects of technology, with the technical advantages it brings, Proportional pneumatic feedback for air suspension control, exceeding its current state. A valve exhaust port utilization system has been developed. Explaining the Figures 5 Figure 1; Front axle, dual-wheel axle, single-wheel axle main axle in the known state of the art. This is a schematic drawing of a control valve. Figure 2; Front axis created with feedback track in a representative application of the invention. This is a schematic drawing of the main control valve for both double-wheeled and single-wheeled axles. 10 Figure 3 shows a diagram of a proportional valve in a representative application of the invention. Reference Numbers Detailed Explanation of the Discovery The invention involves the height of the double-wheeled drive axles (2) and the single-wheeled rear axles (3) in the air. through the main control valve (4) which controls the pressure and the feedback line (7) When driving on rough road conditions, the air outlet, the expulsion of air from the exhaust port 20 air created by at least one feedback proportional pneumatic valve (6) that blocks Proportional pneumatic valve (6) exhaust port as feedback for suspension control It is related to the usage system. In Figures 1 and 2, the front axle (1), the dual-wheel drive axle (2), and the single-wheel rear axle (3) are pressure 25 main control valve (4) which controls the electronic control unit (ECU) (5) It is shown. 1 Front axle 5 Electronic control unit 2 Double-tired axle with date range 6 Proportional pneumatic valve 3 Single-wheel rear axle 7 Feedback lines 4 Main control valves -4- The main control valve (4) shown in Figure 1 is required for the defined vehicle height. It is adjusted to the pressure level. The vehicle's height is determined by the load in its static state. It provides the required amount of air by adjusting the main control valve (4), vehicle static It regulates the airflow while in this state, any while the vehicle is in dynamic condition. It does not make any changes. 5 In the diagram in Figure 1, the exhaust port of the proportional pneumatic valve (6) shown in Figure 3, It expels air to distribute the necessary air to the rear axle. This is a proportional pneumatic valve. (6) works with a ratio of 1.2, for example. That is, an inlet pressure of 1.2 bar will produce a pressure of 1 bar. Provides outlet pressure. 10 This is achieved by expelling air through the exhaust port. This loss of air affects the driving experience. This causes a loss of pressure and a decrease in vehicle height during (dynamic) operation. Therefore, the feedback line in Figure 2 (feedback from exhaust to main line) (7), It will compensate for uneven road conditions and allow air to escape dynamically. will not allow it. Because the main line pressure will be regulated by the main control valve (4). The static state condition will also remain unaffected. The invention provides feedback for air suspension control in heavy vehicles and trucks. The proportional pneumatic valve (6) is related to the exhaust port usage system and its feature is; 20 main control valve (4) and electronic control which control the pressure on the axles unit (5) has at least one feedback line (7) connected to the main control valve (4) or return supply line, feedback line (7) or exhaust port via feedback line enabling use in rough road conditions and dynamic air circulation. It is characterized by containing at least one proportional pneumatic valve (6) which prevents obstruction. 25 Front axle (1), double-wheeled drive axle (2), single-wheeled rear axle (3) under pressure control pressure loss and vehicle height reduction during driving (in dynamic conditions) to prevent this, by compensating for bumpy road conditions and dynamic exhaust system.
