Online automatic inflation system for dual-tire automobile tire

Abstract

The invention discloses an online automatic inflation system for a dual-tire automobile tire. One side of a vehicle air bag is connected with an air inlet valve through a hose; one side of the air inlet valve is connected with the air inlet of a pressure protection valve; the air outlet of the pressure protection valve is connected with the air inlet of a drying filter; the air outlet of the drying filter is connected with the air inlet of a reducing valve positioned in a control box; the air outlet of the reducing valve is connected with the air inlet of a boosting valve positioned in the control box; the air outlet of the boosting valve is connected with the air inlet of a flow control valve positioned in the control box; the air outlet of the flow control valve is connected with one end of an air outlet valve positioned outside the control box through a hose; the other end of the air outlet valve is connected with a main air inlet tube. By adopting the online automatic inflation system, the pressure of each tire can be monitored wirelessly in real time, and each tire can be inflated automatically on line to keep the air pressure of each tire in a normal tire pressure range; the online automatic inflation system has the advantages of capability of ensuring safe running of an automobile, saving of fuel, small tire abrasion, longer service life, simple structure and convenience in mounting.

Description

[0001] Technical field: [0002] The invention relates to an on-line automatic inflation system for twin-type automobile tires. [0003] Background technique: [0004] In the market, many large passenger cars, heavy-duty trucks, trailers, dangerous goods transport vehicles and off-road vehicles all adopt a double-tire structure due to load requirements. When the vehicle is running normally, due to the uneven road, the load of the dual tires is different, and the conditions of heat and cold are also different, so the pressure of the two tires is not the same, which leads to greater wear of the tire with high pressure, and accelerates the aging of the tire. It greatly affects the service life of the tires; if the tire pressure of the dual tires can be balanced and kept within the specified value, the operation of the vehicle will be more stable, safer and fuel-efficient, the two tires will wear evenly, and the service life will be longer. [0005] At present, in order to balance...

Problems solved by technology

[0005] At present, in order to balance the air pressure between the double tires, people mostly use a double tire pressure balancer, but this can only alleviate the situation that the difference between the two tires is small, because when the tires are in use, the safe air pressure range is 10 -12kpa air pressure, if the air pressure is lower than 10kpa, the use of itself cannot be guaranteed. If the air pressure difference between the two tires is large or one tire leaks slowly, it will not only fail to balance the air pressure between the two tires, but also reduce the normal tire pressure. The air pressure of the tires will cause the air pressure of the air supply tires to be lower th
