Chassis

The chassis engineering is one of the biggest challenges in truck engineering. An immense variety of vehicle variants and applications for different markets with different requirements and therefore with correspondingly different components must be taken into account. The Engineering Center Steyr Vehicle Engineering covers the entire scope of the chassis development, from the modular concept to series documentation. This includes design, calculation, simulation for strength and fatigue, ride and handling as well as testing for frames, add-on parts, axles, suspension, and steering as well as integration of powertrain including cooling, electrics, brake system and acoustics. From cars to commercial vehicles and special vehicles, with independent suspension or rigid axles, our experience covers both the entire chassis development and system integration for these vehicles.
