ContiTech develops new strut mount for car chassis

Lightweight variant with fiberglass-reinforced polyamide 25 percent lighter than aluminum design.

Enhanced Safety, Even Under Extreme Stress
In passenger cars, the spring strut mount is the interface between the spring strut and body. It enables precise and low-friction rotational movement of the spring strut in the front of the vehicle, thereby ensuring optimum contact of the tire to the road. The vehicle is easier to steer.

As a chassis component, it is subjected to extreme stress. Spray water, road salt, sand, gravel, and vibrations can cause the spring strut to wear. If it is no longer fully functional, the shock absorbers - among other things - are more highly stressed. Vibrations and noise from the axles are more pronounced, resulting in reduced ride comfort.

The new two-section, three-path bearing from ContiTech comprises both fiberglass-reinforced polyamide and aluminum components. This brand-new design can even withstand shock loading as high as 75 kN, equivalent to driving a car along a badly potholed road. The strut mount also ensures that only minimal counter torque acts on the shock absorber. This component too is subjected to less stress which, in turn, enhances safety in the vehicle.
