Lubrication solutions for alternative materials, high
efficiency and smooth
functionality in cars Klüber Lubrication at the IZB 2010 Wolfsburg, Hall 5, stand 098
For-life lubrication of automotive components is a constant challenge for design engineers, particularly if alternative materials are used. Whenever light materials such as plastics are used to reduce the overall weight of the vehicle and hence to reduce the fuel consumption, cooperation with an experienced tribologist at an early stage is vital: only lubricants perfectly compatible with the materials involved can ensure reliable component operation for the required lifetime. The interaction of lubricants and plastics is one of the key research issues for Klüber Lubrication’s Research & Development team. The internationally active lubrication specialist will be presenting innovative solutions for automotive components such as seat recliners, door modules, brakes and highly loaded small gears at the IZB Wolfsburg.
Smooth running is another key issue: speciality lubricants can increase component efficiency significantly, reducing the required driving force and hence the energy consumption. The experts from Klüber Lubrication will be presenting lubrication solutions ensuring high efficiency due to low friction while providing component reliability, e.g. in actuators in the steering system, in engine components, seats and window lifters.
The stand team will also be providing information on speciality lubricants increasing comfort in the vehicle’s interior. Bonded coatings and damping greases reduce oscillations and vibrations and avoid noise generation. They help design engineers fulfil the increasing requirements regarding the feel of control elements, noiseless function and undisturbed driving pleasure.
Klüber Lubrication has developed more than one hundred different lubricating greases, oils pastes and bonded coatings for the automotive industry alone, many of them custom-made in close cooperation with OEMs. Klüber products can be applied to approximately 150 friction points in a car.

First double-clutch transmission in a truck
• Fuso is the first manufacturer worldwide to present a double- clutch transmission in commercial vehicles
• Known as the ‘Duonic’, this double-clutch transmission combines automated driving with the advantages of a manual transmission
Fuso has presented a world first with a double-clutch transmission for commercial vehicles. The new transmission drives like an automatic transmission, but unlike a fully automatic torque converter transmission, it makes for lower consumption figures and therefore lower exhaust emissions. The double- clutch transmission is an automated manual transmission. As with a fully automatic transmission it is a two- pedal system, there is an accelerator pedal, a brake pedal and a selector lever. The selector lever allows automatic or manual gearshift mode to be selected.
The M038S6 Duonic transmission has six forward gears and a reverse gear. The P-function ensures safe parking by preventing the vehicle from rolling away. Duonic features a non-wearing wet clutch, which lowers

need to replace worn clutch discs. A creep function has been added to the wet clutch, as is usual for automatic transmission with a torque converter. This enables the vehicle's speed to be easily controlled when moving slowly – for example when manoeuvring or in stop-and-go traffic – and hill-starts are also made easier.
