Electronic Air Spring Damper Modules (LFDs)

Our air spring damper modules unite the features of air springs and air dampers in a single module:

When coupled with an ECU and a valve block, the air spring damper module, with its integrated ultrasonic height & pressure sensor, forms a complete electronic system and offers a broad range of benefits, such as:

  • Enhanced driving comfort and improved acoustics in the case of a stiffer suspension thanks to frequency selective damping
  • Load adaptive damping improves driving safety and supports a broad range of applications
  • Integrated UHPS (Ultrasonic Height & Pressure Sensor) for increased measurement accuracy and reduction of components
  • Fuel savings thanks to a reduction in the amount of air consumed through the use of an electronically controlled height leveling system
  • Reduced Total Cost of Ownership (TCO) thanks to the extended service life
  • Environmentally friendly due to the lack of damper oil

Additional Features 

Kneeling function – Provides easy access to the cab while boarding or during transactions at toll gates and delivery and dispatch areas
Automatic lowering of cab height on highways – Automatic lowering of the driver’s cab on highways to reduce drag, thereby reducing fuel consumption
Servicing and trailer coupling functions – Raises the entire cab or tilts the driver’s cab forwards to enable easy access to tight servicing areas or trailer coupling areas
Break/sleep function – Sets the driver’s cab in a horizontal position to enable the driver to achieve a comfortable sleeping position
