ContiTech develops first polyamide strut mount for Cadillac chassis vibration control; 25% lighter

ContiTech Vibration Control has developed a strut mount in which fiberglass-reinforced BASF Ultramid polyamide is also used as the primary structural component. It is the first strut mount made of this material, which is used both in the front and rear axle in the chassis environment of passenger cars. The strut mount offers a weight reduction of around 25% and a longer service life over traditional variants made from steel or aluminum.

At the same time, a highly insulating rubber element enhances ride comfort. In collaboration with General Motors LLC, ContiTech developed the strut mount for the new Cadillac CT6, which is being launched on the market at the end of 2015.

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.

This strut mount is the world’s first fiberglass-reinforced polyamide strut mount designed for use in the passenger car chassis system. For the front and rear axles, there are different versions. Click to enlarge.

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 countertorque acts on the shock absorber. This component too is subjected to less stress which, in turn, enhances safety in the vehicle.

What will the other vehicle manufacturers do, not to use this improved technology?
