Description

Technical Field

[0002] Tire inflation systems have become essential in motor vehicles. These systems are widely used in different types of vehicles, such as trucks, tractors or earthmovers. The main purpose of a tire inflation system is to adapt the tire pressure to different operating conditions, which basically depends on the ground to be driven on and the speed and load of the vehicle using the tire inflation system. The contact area of ​​the tire is affected by the pressure of the tire. At low tire pressures, the contact area increases, while at high tire pressures, the contact area decreases, therefore, the tire pressure needs to be optimized depending on the ground conditions. Lower pressures are used for driving on soft surfaces like gravel, while higher pressures are selected when driving on hard surfaces like tarmac or concrete. In addition, a suitable tire pressure can provide enhanced tire protection, reduced soil compaction, improved fuel consumption and reduced overall operating costs.
