Volkswagen's Direct-Shift Gearbox is an engineering marvel.
Volkswagen's DSG transmission is brilliant. The higher up you go in the model ranks, the better it is. On a top-of-the-line model like the Golf R, the 'box is capable of super fast shifts that even the most proficient user of a manual simply cannot match. It's one of the reasons GTI and R model cars are so quick, especially in a straight line. DSG stands for Direct-Shift Gearbox, or Direkt-Schalt-Getriebe, if you hail from the manufacturer's motherland. Many of us have felt a DSG in action, but how many of us really know how it works?
Luckily we no longer need to wonder how the magic happens thanks to Engineering Explained. Take a look at the many working parts of a DSG transmission.
We cannot hope to match the explanation in the video, so here's how Engineering Explained, well, explains it: "DSG uses two wet, multi-plate clutches to activateseparate drive shafts which send torque via the even or odd gear sets. Becausethe gear sets are on separate shafts, this allows for preselecting the nextgear, allowing for nearly instantaneous gearshifts without a total loss intorque. DSG transmissions operate a lot like manual transmissions, but they areelectronically controlled and thus the gear selection can be either automaticor manual, but does not require the use of a clutch pedal as this is allactivated automatically." This is one system that Volkswagen got very, very right.
