Global technology giant Schaeffler has just celebrated the production of its 10 millionth continuously variable transmission (CVT) chain.

The innovation was first used in the so-called ‘Multitronic’ transmission in Audi’s A6 models in 1999 with just 50 pieces being produced per day. Today 6000 chains roll off the production line at Bühl, Germany every working day, with production set to continue to grow.

It was the multi-link chain produced by Schaeffler’s LuK clutch brand that made the CVT suitable for high torque transmissions, from development through to volume production.

Modern transmission automation concepts, such as those being developed by Schaeffler, are helping vehicle manufacturers to meet increasingly tougher emissions and efficiency targets whilst delivering maximum comfort and driveability.  The results of these developments can be seen in the vast number of drivers around the world that are being convinced of the benefits of driving without a clutch pedal.

Another argument in favour of the CVT is the fact that the gear ratio is continuously adjusted, with no interruption to the tractive force, which means that the engine is always operating at its optimum efficiency level.
