Voith Hydrodamp
Voith Hydrodamp is a highly elastic vibration damper comprised of a spring-mass system and a separately arranged damping system. Critical resonance is shifted, low vibration amplitudes are isolated, and higher amplitudes are damped.
Dampers in power trains must stand up to a target conflict: on the one hand high damping is required when resonances or load jerks occur, on the other hand this damping is detrimental to vibration isolation in the normal operating range, because engine irregularities in this speed range can cause considerable noise and vibration problems in spite of low vibration amplitudes. This conflict is ideally solved by the decoupled damping ring of Hydrodamp.
The ecological and economical advantage
Hydrodamp allows frequent driving in the economical lower speed ranges and thereby helps save fuel and reduce emissions. Hydrodamp thus ideally complements the modern ecological, fuel saving drive system concepts.
A special feature of the Voith two-mass flywheel is the hydraulic damping effect operating parallel to the springs that can be adjusted to prevailing operating conditions. Resonance stages, jolts and shocks can thus be effectively dampened without having to forego the isolating effect during driving operation. |
