'I sat at home and nearly gave up,' says the man who developed the Doppelkupplungsgetriebe...
I love a compound German word, and Doppelkupplungsgetriebe is a cracker. Double-clutch gearbox. That’s what it means, or PDK for short when talking about the Porsche one. And the story of the PDK began more than 40 years ago. Rainer Wüst was the man at the helm of its development programme, and at the time he was the tender age of 35.
“There were neither powerful control electronics nor vehicle-compatible electrohydraulic valves in series production. We got the Szodfridt transmission from storage and worked with pneumatic valves, which we converted to work hydraulically. It was complicated pioneering work from the ground up, but the result already had pre-series status,” he says.
Still, there were some issues to solve. The smoothness of the gearchanges for one, which was unsettling the racing car during changes. The clutch control wasn’t very smooth, so every time the driver shifted a gear there was ‘a hefty jerk.’ And according to Wüst, those jerks also “put great stress on the transmission – and the entire driveshaft. On a few occasions, this excess torque sent everything flying around us, and I sat at home in the evenings and nearly gave up on the whole thing.
