Improve cost-effectiveness with the Voith Hydrodamp
High-torque commercial vehicle engines that are optimized for consumption are more demanding on the drive train today than before. This demand results in substantially greater component wear. The advanced Voith Hydrodamp torsional vibration damper works against these conditions.
It provides hydraulic damping and isolates vibrations of the drive train to protect against overloads and to extend the service life of all components. As a maintenance-free unit located between the engine and the transmission or drive shaft, it "has flexible reactions to complex vibration scenarios. The Voith Hydrodamp recognizes the different needs between vibration damping and vibration isolation and adjusts appropriately using its hydraulic principle of operation. As a result, it reduces vibration and noise, increases comfort and improves cost-effectiveness. The vibration damper is available in three vehicle-specific and application-specific series for engine torques up to 3,700 Nm. Each can be adjusted in terms of damping and spring characteristics to suit individual customer requirements. Equipped in this way, the flexible Voith Hydrodamp has proven itself in the tractors, construction machinery, buses and rail vehicles of leading manufacturers.

Experience and development competence
The Hydrodamp is the result of talent and experience that have been developed over decades together with knowledge gained in the area of hydrodynamics. Many years of international project partnerships with customers and universities in collaboration with the high skill level of our employees allow Voith to set the standards in the development of innovative, goal-oriented products.
Function: How the Voith Hydrodamp works
When passing through resonance points (e.g., when starting or stopping the engine) and in the event of load surges during operation, dampers in drive trains must provide a great amount of damping energy. In the operating range, however, this is precisely what makes vibration isolation more difficult. Engine irregularities can lead to significant vibration and noise problems – a dilemma that the Hydrodamp solves.
