DualRubber Bushings

DualRubber bushings are an alternative to conventional chassis bushings and more complex hydro bushings. By using two different rubber compounds respectively in the vertical and horizontal direction, DualRubber bushings help meet contradictory requirements in rear axle twist beam applications. Vertically they provide low damping and good acoustic isolation, while horizontally they offer high damping for improved shock absorption and aftershake.

Built into a lightweight plastic housing, this further enables the integration of radial limitations for precise tuning to customer needs. DualRubber Bushings are cost- and weight-efficient compared to more complex solutions like hydro bushings, and are therefore a good choice for lower and medium segment vehicles.

About Chassis Mounts

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 a number of 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.
