Top mounts are structural elements subject to heavy loads and permanently exposed to harmful environmental effects such as heat, road salt or ozone.
These factors also apply to lightweight fiber-reinforced top mounts. Therefore, specific design processes were developed to take into account the multidirectional properties as well as the humidity and temperature sensitivity of fiber-reinforced plastic. Even at high temperatures, under difficult conditions or during an accident, top mounts retain their strength and stiffness.
The material combination perfectly bonds the shock absorbers to the chassis and thus ensures improved driving comfort and dynamics. The natural rubber compound can therefore be precisely tuned to the customer needs, either providing controlled damping or low stiffness.
In addition, lightweight plastic top mounts are significantly lighter than conventional metal mounts, without compromising on performance. As a result, they help increase the efficiency of the vehicle.
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.
