Rubber-to-metal Components

Rubber-to-metal Components
More Comfort in the Passenger Cabin

A solid combination of rubber and metal creates multifunctional POLADIUM automotive components that transmit forces, enable defined movements, isolate noise and dampen vibrations. Therefore, vibrations and noise caused by the transmission or the engine are hardly noticeable in modern vehicles – thanks to vibration-optimized concepts with innovative and safe powertrain mounts.

Secure fixation – pleasant damping

POLADIUM rubber bearings for the driveline securely fixate the engine and transmission and increase the ride comfort for the passengers. The metal-to-rubber components in the driveline include engine mounts, transmission mounts, and torque support arms.

They form the damping connection of the engine and transmission with the chassis and secure the units in all driving situations. Furthermore, the bearings ensure that the driver and the passengers are protected against bothersome vibrations and noises.

The intelligent connection between rubber and metal

Depending on the vehicle model, up to 15 rubber-to-metal components may be installed in a passenger car. The vulcanized connection between the metal and rubber transfers pressure and shear forces and simultaneously insulates oscillations, vibrations and structure-borne noise.

That is the reason why rubber-to-metal components have a decisive influence on driving characteristics and driving safety. The POLADIUM composite parts are therefore designed in an innovative manner and are geared towards a particularly long service life.

Conventional, hydraulic or switchable engine mounts

Conventional engine mounts are intelligently designed rubber-metal or rubber-plastic constructions that provide mechanical damping. Hydraulic engine mounts, also referred to as hydromounts, additionally work with an oil damping. Within the rubber element, the liquid ensures a flow resistance that softens jolts and vibrations. Hydraulic mounts are used wherever an elastic mounting with frequency-dependent damping is desired – on engine mounts, link mounts or axle housing mounting, for instance.

Switchable hydraulic mounts or active mounts can also adjust the damping characteristics of the unit to its respective operating condition via gear changes.
