Road Wheel Actuator
The Schaeffler Road Wheel Actuator (RWA), featuring a dedicated steer-by-wire architecture, enables dynamic and precise vehicle control as well as direct driver feedback without a mechanical connection. This innovative platform concept replaces traditional steering systems in vehicles with front-wheel steering and improves both the driving experience and safety. Suitable for all vehicle segments up to SUVs and light trucks, the RWA offers numerous customization options and maximum installation flexibility thanks to optimal packaging.
