- 25% weight reduction compared to aluminum variant
- Less noise and vibration despite high crash protection
For the first time, ContiTech from Hanover in Germany has developed a transmission crossbeam from fiberglass-reinforced polyamide BASF Ultramid for the rear axle, which is used in the Mercedes-Benz S-Class. The new variant is about 25 percent lighter compared to diecast aluminum versions. The rear axle transmission crossbeam from ContiTech is used in Mercedes-Benz vehicle models with all wheel drive, with the exception of the AMG range.
High strength meets good NVH performance
Polyamide: the material with high potential
Since 2006, ContiTech Vibration Control has been using BASF Ultramid for bearings in automotive construction and has received design awards for its work. Products include heavy-duty engine mounts, with the annual production volume in 2013 exceeding three million. In 2009, the bearings specialist also launched a lightweight transmission crossbeam from the lightweight material to support the forces and torques of the engine transmission unit. The weight is 50 percent less compared to a component made from aluminum. ContiTech produces the component in an injection molding process. ContiTech has already delivered millions of torque reaction mounts made from polyamide.
