High frequency vibrations leading to interior noise issues can derive from many sources, including transmissions and differential gearboxes as well as electric and hybrid drive units. A conventional rubber spring provides static and dynamic stiffness and damping.
Using steel or aluminum inlays within the rubber spring, the resonance frequency can be precisely tuned without compromising on other mount requirements like static stiffness, durability and packaging space. Also, lightweight aluminum can be used for the inner core and outer sleeve to save on overall weight.
Motor mounts control engine movement in all directions, guaranteeing excellent driving comfort and driving dynamics without compromising performance.
About Motor Mounts
Motor mounts carry the static and dynamic loads of the motor throughout its entire service life and are also 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.
