Compressed air systems in commercial vehicles - an overview
Air... a great thing
Modern commercial vehicles and trailers with a total weight of more than 7.5 tons rely almost entirely on pneumatic braking and suspension systems. These systems have replaced the earlier hydraulic solutions - and for good reason.
How it works
The compressed air system uses compressed air, which is generated and stored by a compressor. This air serves as the driving force for various components:
- Brake systems use compressed air to activate brake cylinders that press the brake linings against the drum or disk.
- Suspension systems ensure stability and comfort by dynamically adjusting the air pressure.
- Clutch and transmission control systems use air pressure to optimize gear changes.
The advantages of compressed air
- Inexhaustible resource: Air is available everywhere and at all times, does not need to be stored and does not incur any material costs.
- Easy to maintain: Unlike liquids, air does not age, is not subject to wear and tear and does not require disposal.
- Environmentally friendly: Excess or used air is simply released back into the environment - without recirculation or disposal.
