How the dampers work

SUSPA® dampers are suitable for damping shocks and vibrations. All dampers developed by SUSPA® are designed for the respective product application in such a way that an optimim movement sequence or optimum vibration characteristics are achieved.

Movement energy converted into thermal energy

Dampers are damping elements that convert the kinetic energy of moving parts into thermal energy and thereby reduce hard shocks or avoid excessive oscillation amplitudes. The dampers are also know as shock absorbers, industrial dampers or hydraulic dampers.

Structure of a damper

Dampers consist of a pressure tube, a piston rod with a special piston system and the damping medium oil. This is why they are frequently called hydraulic dampers. The piston rod is located within the oil-filled pressure tube with its special seal and guiding system which hermetically seals the inner compartment of the hydraulic damper against the atmosphere - also under extreme environmental conditions. The damping oil is pressed through the damping bores in the piston system through the movement of the piston rod. The damping forces are therefore always also dependent on the piston speed..

Damping forces

Since the damping borings can be closed respectively on both sides by valve washers, it is possible to regulate the damping forces in the direction of extension and compression largely independent of one another. The damping force on compression determines the hardness of a shock absorber on retraction. The damping force on extension regulates the extension speed.

Characteristics of the damper

The linear, progressive, degressive characteristics to be set make possible an application-oriented damper design.
