ContiTech Develops First Polyamide Rear Axle Transmission CrossbeamNew performance class with lightweight technology: The new ContiTech transmission crossbeam for the rear axle is used in the Mercedes-Benz S-Class.

ContiTech uses its expertise in lightweight construction to conquer other areas of application where metal once dominated. For the first time, the bearings specialist 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. The component boasts optimum strength, good NVH performance, and high crash-protection. As a central component of the rear axle, it supports forces and torques of the rear axle transmission.

Polyamide components make an important contribution in terms of reducing weight and making vehicles more environmentally friendly. Unlike aluminum, polyamide can be shaped at lower temperatures, thus requiring significantly less energy in the manufacturing process. There is also a wide range of possibilities in recycling.

At the Hannover Messe (April 13 to 17), ContiTech will be presenting the rear axle transmission crossbeam at its booth F18 in hall 6.
