Front element for road vehicles esp. trucks and buses

摘要

The front element (2) is inflatable. It consists of several inflatable chambers (3) made of flexible sheet material. The chambers can be inflated by a compressor (4) via a control device (5) with regulating valves to form a streamlined nose on the vehicle (1), which reduces air resistance when the vehicle is in motion. The air pressure in the chambers is controlled by the control device, depending on the speed of the vehicle
