Volkswagen wins award for its DSG transmission
Wolfsburg, Germany – Volkswagen has been awarded this year’s innovation prize by AutoBild test&tuning for the development and implementation of the direct selection gearbox DSG. The prize was presented last Friday at the Essen Motor Show.
Dr. Wolfgang Schreiber, Head of Gearbox Development at Volkswagen, accepted the award. “We are very pleased to be given this prize…The DSG is an innovation with which Volkswagen has once again set a technical benchmark. This is made evident by almost 60 patents that were awarded during development of the DSG.”
The DSG was introduced on the market at the start of 2003 in the Volkswagen R32. DSG has been an option in the Touran since the end of September. The new Golf will be available in the first half of 2004 with DSG.
One of the design features of the transversally installed gearbox is the dual wet clutch (higher thermal resistance than dry clutch), which is actuated extremely quickly, yet with a soft and accurate feel. The so-called K1 clutch operates the uneven gear numbers (including reverse) and the K2 clutch operates the even gear numbers. Each gear change is carried out as one clutch opens and the other closes. The reason for this complicated clutch management system is to prevent typical gear change jolts, common on automated gearboxes.
The DSG features two fully automated gear selection programmes and a Tiptronic function, which allows manual gear selection. The gearbox control unit also ensures, via ABS wheel speed sensors, that the programme does not change up a gear automatically during cornering.
