ContiTech at IAA 2010

Solutions for the new generation of engines

Engine modifications alone can in the meantime hardly ensure compliance with the strict standards and limits for commercial vehicle emissions. ContiTech helps manufacturers meet stricter emissions standards. With the second generation of hose lines for the Selective Catalytic Reduction (SCR) exhaust gas purification technology, ContiTech has assumed a pioneering role. By means of a carbamide solution (AdBlue), noxious nitrogen oxide (NOx) is transformed into water vapor and nitrogen. The new generation of hoses has heated quick connectors with optimized bonding, guaranteeing consistent thawing of the medium, even close up to the plug connector. In the future, three SCR line types will be available: the previous standard solution; an advanced, higher-quality rubber hose; and a plastic solution.

ContiTech Fluid Technology has developed extremely resilient fuel lines especially for high-power truck engines with up to 16 l capacity and reduced fuel consumption. The new lines can withstand pressures of up to 35 bar and operating temperatures of up 130°C. Conventional lines are not able to cope with the requirements of these heavy duty engines.

Air spring systems with state-of-the-art technologies

A new technology has been made possible by smarter air spring systems. ContiTech is the first manufacture to succeed in integrating electronic data storage into its air spring bellows. The transponder chip defies the high temperatures prevailing in the manufacturing process as well as the pressure and elongation occurring when the bellows are in service. Chip technology opens up whole new possibilities: Vital product information can now be monitored electronically and remains fully accessible even years later – despite contamination and wear in the intervening time. Every air spring system can be unmistakably identified at any time. The service information is stored and updated whenever the system is serviced. This allows for optimum replacement of air spring systems. The chip also protects the manufacturer and operator from product counterfeits.

An important contribution toward a reduction in weight and more cost-efficient production is made by a new air spring system in which the beveled plate is not made of metal but of plastic instead. The plate is vulcanized in already in the production stage. The new system from ContiTech has gone into production for a large commercial vehicle manufacturer in July 2010.

Special foil as low-price alternative to injection molded parts

The surface specialist Benecke-Kaliko has developed the new DecoJectTM thin foil as a low-cost alternative to lacquered injection molded parts. This foil opens up new interior design options with an expanded range of colors, patterns and effect paints. In contrast to injection molded parts, the foil makes it possible to match the color and shine to the other components. It is also scratch- and wear-proof and pleasant to the touch. In addition, simple interior decor changes require little set-up time.

Flexible elastomer solutions for trucks and buses

Greater safety is to be provided by a rubber lining for fuel tanks in commercial vehicles. The 1.2 mm thin material is inserted in the tank as a second protective skin with the purpose of enhancing safety in the event of a crash. The material is already used successfully in motor racing and is known for its remarkable puncture- and tear-resistance. A further highlight is the new generation of translucent concertina walls for articulated buses. Thanks to a newly developed special anti-stick material, the concertina wall is now also resistant to course dirt or graffiti. The translucent characteristic provides light refraction, thus intensifying the degree of brightness. Passengers inside the bus feel safer. The concertina wall is now also suitable for vehicles with cable ducts in the roof area.
