Rubber-to-metal components in the driveline

More comfort in the passenger cabin

Bothersome vibrations and noises generated by the transmission and engine can hardly be heard in modern vehicles thanks to vibration-optimized concepts with innovative and safe powertrain mounts.

Secure anchorage – pleasant damping

LEMFÖRDER rubber bearings for the driveline securely anchor 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 flexible disks.

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 passengers are protected against bothersome vibrations and noises.

Nowadays, the LEMFÖRDER rubber-bonded metal mounts are also used for harmonizing the engine timbre.

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 LEMFÖRDER composite parts are therefore designed in an innovative manner and are geared towards a particularly long service life.

Conventional, hydraulic and switchable engine mounts
Different types of bearings

Conventional, hydraulic or switchable bearing?

Conventional bearings are intelligently designed rubber-metal or rubber-plastic constructions that provide mechanical damping. Hydraulic bearings, also referred to as hydro bearings, additionally work with an oil damping. Within the rubber element, the liquid ensures a resistance to flow that softens jolts and vibrations. Hydraulic bearings are used wherever an elastic mounting with frequency-dependent damping is desired – on engine mounts, link mounts or axle housing bearings, for instance. Switchable hydraulic bearings or active bearings can also adjust the damping characteristics to the respective operating condition of the unit via gear changes.

Task and function of the various bearings in the driveline

Engine mounts, transmission mounts, and flexible disks perform important tasks in the vehicle.

    As a connection between the engine and the body, engine mounts absorb the static engine load. They limit the engine movement, thus ensuring a damping of the vibration and structure-borne noise transfer into the body.

    LEMFÖRDER engine mounts - benefits:

    • Engine mount individually aligned to the engine perfomance
    • Complex and harmonized internal structure
    • With hydraulic engine mounts, the hydraulic function takes care of the damping
