Torsional Vibration Dampers absorb rotational vibrations in internal combustion engines. The dampers are particularly effective in conjunction with decoupled pulleys, which keep crankshaft irregularities away from the belt drive and auxiliaries. In fuel-efficient start-stop systems, they eliminate the effects of an engine that is constantly starting and stopping. With an additional one-way-clutch feature, they can enable further savings in fuel consumption and CO2 emissions.

Light vehicle manufacturers are being increasingly challenged to downsize components to reach global targets for fuel consumption and CO2 emissions. The result is smaller engines with fewer cylinders that compensate for reduced capacity by building up increased pressure and enabling more efficient combustion. This generates stronger vibrations in the crankshaft. Torsional vibration dampers compensate rotational vibrations in the engine and the irregularities of the crankshaft are kept away from the belt drive, also ensuring optimized durability.

Vibracoustic offers pressed, high torque, vulcanized and fluid torsional vibration dampers, damper isolator pulleys with an overrunning feature, as well as sprocket dampers.

Motor mounts carry the static and dynamic loads of the motor throughout its entire service life and are an important factor for isolating low to high frequency vibrations. Downsized and turbocharged motors are state-of-the-art to reduce fuel consumption but lead to high vibration levels.

Motor and transmission mounts consist of a motor or gearbox support arm, an isolation element and a body-side connecting element. The critical element is the rubber spring that dampens vibrations, supports drive torques and isolates noise during start-up. The motor mount prevents booming noises and load-change shocks. Vibrations of the body and drive train are improved by using a hydraulic damping system. Motor mounts effectively isolate motor vibrations and dampen road excitations to ensure a comfortable driving experience.

The product portfolio ranges from conventional rubber mounts and hydro motor mounts, through electrically or pneumatically switchable motor mounts, to gearbox mounts and torque rods.

Vibracoustic Metal Rubber Parts Commercial Vehicles (MTC) are designed to provide various functional benefits by combining the properties of both metal and rubber in order to ideally absorb and dampen vibrations and noise. To address every aspect of vehicle performance, our MTC portfolio includes motor mounts, cabin mounts and chassis mounts. By combining the properties of both materials, metal rubber parts can reduce the need for multiple separate components, saving weight and cost.

Dozens of chassis mounts control vibrations transmitted from the road surface into the chassis of the vehicle. Chassis mounts are small but important components that improve handling and safety, and reduce unwanted vibrations.

All bushings are designed to absorb loads, caused by road surface excitations, from multiple directions. The correct stiffness and damping of the bushings are essential to maximize vehicle road holding, ride and handling. Bushings must therefore be precisely tuned in line with the whole suspension system.

Minor vibrations create an unpleasant driving experience – severe ones can result in steering disturbances and body vibrations that pose serious safety risks. To reduce vibrations, vehicles have several chassis mounts fitted, e.g. for the transverse control arms, subframes, suspension struts and stabilizers.

The product portfolio ranges from conventional, hydro, DualRubber chassis bushings through steering column bushings, and subframe mounts to conventional and lightweight top mounts.

Vibracoustic supplies air springs for the majority of all Light Vehicles based on air suspension systems, making us one of the leading global air spring manufacturers.

Our products can be delivered separately or as a unit with the damper. The Vibracoustic portfolio ranges from front and rear axle air springs to switchable multi-chamber air springs Our comprehensive air springs know how makes us a reliable component and module supplier for air spring applications of all sorts.

The key element are rubber bellows. They determine essentially the comfort and service life properties. Vibracoustic offers three different types of bellows – axial, cross-ply and ZAX – which differ in terms of structure of their embedded reinforcing fibers.

In an axial sleeve, the fibers embedded in the elastomer run axially to the deflection direction. The cross-ply bellows has two layers of reinforcing elements, placed at an angle to each other. Unlike in a fabric, these elements are not connected. The cross-axial bellows, or ZAX bellows, combines the high torsion decoupling capability of an axial sleeve with the dimensional stability of a cross-ply bellows
