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
