Design and tuning of the suspension and damping always necessitate a compromise between the criteria of importance to the customer, namely ride comfort on the one hand and driving safety and agility on the other.

DampMatic^®:

• Passive amplitude-selective damper adjustment system

• Extends the piston rod assembly to include a DampMatic® module comprising the housing and DampMatic® piston

• At lower excitation amplitudes, the DampMatic® module permits a bypass to the main piston -> reduced characteristic, lower damping forces

• At higher excitation amplitudes, the DampMatic® piston reaches its limit position and closes the bypass -> high damping forces

• Installed as standard in Mercedes-Benz class A and B vehicles

Advantages:

• Low-cost passive adjustment system

• No control device, no sensors

• Robust design, few components

ACD II:

• 2-stage electronically adjustable damping system

• A bypass to the hollowed stud is opened and closed by a slide valve actuated by an electromagnet integrated into the piston rod

• Soft characteristic is determined by valve actuation in the bypass line

• Hard characteristic is achieved by valve actuation on the working piston

ADS:

• 4-stage electronically adjustable damping system

• Hardware Skyhook by combining a soft and a hard characteristic for extension and compression stages in the adjustment characteristics

• Two pistons in an external adjustment module can be individually connected in parallel to the conventional working piston.

• The four characteristics are as follows (extension/compression): soft/soft ; soft/hard ; hard/soft ; hard/hard

  

DampTronic^®:

• Electronically infinitely adjustable damping system

• Bypass adjustment with multi-way valve technology - an infinitely adjustable slide opens a bypass line to the main piston with hard actuation

• Comfort valve with soft actuation integrated into the bypass line

• Design with control valve integrated into the piston (DampTronic^® I) and with externally adapted control valve (DampTronic^® II)

• Hard and soft characteristics are determined by highly dynamic, passive disk valves

• Large spread in the area of low damper speeds (advanced opening control)
