Voith Hydrodamp – Vibration dampers for modern commercial vehicles

Our Hydrodamp vibration damper series for tractors, construction machinery, buses, trucks and rail vehicles

Modern, high-torque and fuel-optimized engines place significantly more strain on drive trains than before. Our Hydrodamp vibration damper series protects the drive train of tractors, construction machinery, buses, trucks or rail vehicles from overload and increases the service life of the individual components.

The Hydrodamp is a highly elastic vibration damper with a spring-mass system and a separately arranged hydraulic damping system. The low spring stiffness in conjunction with favorable mass ratios relocates critical resonances to areas below the Operating speeds. Regardless of this, the hydraulic functional principle for vibration damping and isolation is designed for the operating speed ranges.

The vibration damper is available in three vehicle and application-specific series for engine torques of up to 3,700 Nm. Each can be customized in terms of damping and suspension characteristics. Equipped in this way, the flexible Voith Hydrodamp proves itself in tractors, construction machinery, buses, trucks and rail vehicles from leading manufacturers.

Hub or cardan shaft connection

The Hydrodamp ranges have been developed based on a modular principle. The connection to the customer’s own individual drivetrain is achieved by means of solution variants for primary and secondary side, such as SAE centering flanges, hubs and cardan shaft connections. Within the series, by adjusting the characteristic curve and damping characteristics, the Hydrodamp can be precisely adapted to the drivetrain’s requirements.

Hydrodamp 365 AG

The new Hydrodamp 365 AG – especially developed for agricultural tractors

Hydrodamp 365 HT - vibration dampers for commercial vehicles

Brings peace to the driveline – also for heavy agricultural tractors.

The Hydrodamp agricultural range has been specifically developed for the drivetrains of state-of-the-art, powerful agricultural tractors. The higher torque capacity caters for the increased requirements of modern engines. Optimal reduction of torsional vibration maximizes vehicle operation efficiency.

  • Increases the service life and operational availability of your tractor.
  • Reduces fuel consumption.
  • Enables the use of high-power engines (downsizing).
  • Increases driving comfort due to reduced vibrations.

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.

Damping and isolating in one single system

Vibration dampers – Damping and isolating in one single system
No sticking phases_Icon

No sticking phases followed by breaking free meaning no vibration stimulation as with conventional friction damping.

Damping effect_Icon

The damping effect can be matched to operating ranges by way of the torsion angle, gap geometries and the viscosity of the damping medium.

Greater damping_Icon

Damping is proportional to speed meaning that higher frequencies or amplitudes result in greater damping.

Damping is wear-free_Icon

Damping is wear-free.

The operation principle of the Voith Hydrodamp

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.
