IAA Commercial Vehicles: ContiTech Achieves Quantum Leaps in Truck Development

Air springs with plastic pistons save weight and increase ride comfort / Components promoting more safety, comfort and environmental friendliness

Air spring system with an innovative plastic piston: A larger interior volume offers more comfort – and the component is lighter too
(PresseBox) ( Hannover, )
Truck manufacturers want to offer their customers even more driving dynamics, safety and comfort, while also lowering consumption, emissions and operating costs. An important contribution to this has been made by the ContiTech products developed in response to the demands of current and future commercial vehicles. These will be showcased from September 20 to 27 at the 64th International Motor Show (IAA) in Hanover (booth 17, hall A06).

Safety for drivers

Ride comfort plays a decisive role in ensuring that drivers who are relaxed are safer than other drivers. A new development from ContiTech has achieved a quantum leap in this area, with the Air Spring Systems business unit now successfully mass-producing truck air springs with an innovative plastic piston. Its interior volume is utilized to the full to enhance comfort. Up to 75% of the weight of conventional steel pistons is saved thanks to a special type of plastic and a new simulation method, cutting the weight by up to 12 kg per axle. The breakthrough came when the advantages of improved material technology with a completely new type of simulation method cleared the way for a product innovation.

The robust and eco-friendly interior trim material from Benecke-Kaliko comes into play here in the driver's cab interior. ContiTech develops and produces decorative surfaces for instrument panels, sun visors, glove compartment doors, door and side trims, seating and center consoles. This includes the innovative surface material Acella® Eco natural that is made from up to 40 percent renewable raw materials, which in comparison to standard cover material has a 14 percent improved life cycle assessment, and also complies with Öko-Tex® standard 100. Another new development is the DecoJect(TM) thin foil for enhancing unpainted injection molded parts, an alternative - which is just as inexpensive as it is attractive - to lacquered injection molded parts, TEPEO 2® compact sheeting with anti-scratch surfaces and weight optimized Yorn® surface material. But it is not only materials from Benecke-Kaliko that enhance the driver's cab: The air springs for the driver's seat are also ContiTech products, as are the sleeve air springs for supporting the cab itself.

Hose lines for lower emissions

In addition to the air springs, ContiTech also offers numerous other components for modern trucks. The Fluid Technology business unit is particularly active here. The SCR hose line systems are particularly interesting. SCR stands for "Selective Catalytic Reduction", a technology that removes nitrogen oxides from diesel exhaust gases. In the catalytic converter, harmful nitrogen oxides (NOx) are converted into harmless water vapor and natural nitrogen by means of a urea solution. Developed specifically for the SCR method, ContiTech's high-performance hoses ensure that the solution does not freeze and can be safely transported from the tank to the catalytic converter at any temperature. ContiTech Fluid Technology's product range for trucks includes innovative fuel lines with high temperature and pressure resistance, power steering hose lines for weight and noise reduction, hydraulic plug-in systems, aluminum A/C lines, form-bent plastic A/C lines, charge air hoses for EURO 6 applications and cooling hoses for extreme operating conditions.

Drive belts for environmentally-friendly commercial vehicles

ContiTech drive belts make passenger cars and buses more environmentally friendly. An example of these is the long-life poly-V belt, CONTI® HEAVY DUTY POWER, which has been specially developed for commercial vehicles. Thanks to its special EPDM rubber mix, it reduces fuel consumption and CO2 emissions. The highly flexible CONTI® UNIPOWER ECO2-FLEX can reduce the power loss in the ancillary equipment drive, thereby also further reducing fuel consumption and carbon dioxide emissions. With its textile surface, the CONTI® UNIPOWER TOUGH GRIP ensures smooth running under extreme conditions. There is another reason why belts help to protect the environment: The CONTI® UNIPOWER ELASTIC renders clamping systems superfluous, which results in a more compact design and reduces weight.

ContiTech offers numerous other innovative systems that are finding their way into more and more trucks, including air springs and air spring damper modules for front axles and engine mounts to dampen vibrations. With forward-looking technologies, ContiTech makes commercial vehicles safer, more economical and more eco-friendly.
