Central tire inflation system

A tire pressure control system is used to control and monitor the tire pressure in pneumatic tires and motor vehicles. Particularly often such systems in road vehicles, such as military vehicles are fitted. Through the pressure control, the traction of the vehicle in difficult terrain major can be improved.

So to control the tire pressure from inside the vehicle, among other things, most modern military trucks and armored wheeled vehicles, to adjust the ground the tire pressure of the vehicle while driving and to give him a better flotation and traction. Well-known examples are the Tatra truck T 813, T 815 and successors. Even with the U.S. SUV Hummer H1 such a system is available.

But tire pressure control systems on the civilian market are offered. When Mercedes -Benz Unimog for example is called the system " tirecontrol " and for tractors such systems are also available.

The supply of compressed air to the rotating tire is usually done via a hollow axle or hub. The hub is then connected to the valve on the rim. There are also ( retrofit ) systems, where on the rim a rotary feedthrough is mounted to the valve. The compressed air is then guided by means of pipe or hose from the outside to the wheel fender.
