Thanks to its modular design, the ZF axle systems allows for tailored axle configurations, depending on the installation environment. The independent suspension allows for active or passive steering; steered axle systems increase a coach’s maneuverability, enabling much smaller turning circles and reducing tire wear, while ZF’s passive tag axle features steering dampers and pneumatically activated lock cylinders. For active rear axle steering, ZF’s RAS/RAS-EC systems are the perfect solutions.
