Voith Hydrodamp – vibration dampers for commercial vehicles

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, trucks and rail vehicles of leading manufacturers.

    Damping and isolating in one single system Vibration dampers

    Vibration dampers – Damping and isolating in one single system
    No sticking phases followed by breaking free meaning no vibration stimulation as with conventional friction damping.
    The damping effect can be matched to operating ranges by way of the torsion angle, gap geometries and the viscosity of the damping medium.
     
    Damping is proportional to speed meaning that higher frequencies or amplitudes result in greater damping.
    Damping is wear-free.

        Our Hydrodamp range for off-road, road and rail applications

          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.

            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.
