Hydraulic Accumulators and Suspension Systems

Suspension Systems

Excellent driving safety and maximum comfort

Individualized load adjustments using hydraulic accumulators reduce vibration and shock forces under any operating condition.

Excellent driving comfort, greater safety and a long operating life – that is what buyers of agricultural and construction machinery expect. Among other factors, these requirements depend on the suspension systems used on axles, wheels and the cab. With individualized load adjustments using hydropneumatic systems, Freudenberg Sealing Technologies has succeeded in significantly reducing the incidence of vibrations and shock forces. This improves handling characteristics and comfort.

The advantages of hydropneumatic systems include improved handling characteristics and increased safety. They are mainly brought to bear during driving at high speeds as well as in combined loading and transport applications. Full traction is ensured under all operating conditions. Moreover, a variety of individual options are available:

  • Blocking the suspension in any position and switch-on without shock forces 
  • Nick control during acceleration and braking 
  • Active roll control while driving on curves 
  • Adaptive damping

In active damping, the optimal damping setting is calculated with the help of advanced control algorithms for every driving condition.


Excellent driving comfort

Freudenberg Sealing Technologies provides various levels of comfort for the cab suspension as well:

  • Level 1 (standard elastomers) 
  • Level 2 (hydraulic mount) 
  • Level 3 (hydropneumatic suspension) 
  • Level 4 (hydropneumatic suspension with adaptive damping)

As in hydropneumatic axle and wheel suspension systems, adaptive damping calculates the optimum setting of the damping value for any driving condition. When necessary, it can be adjusted on a targeted basis.
