DSG (Direct Shift Gearbox)
DSG is a type of dual-clutch automatic transmission developed by the Volkswagen Group. It combines the advantages of manual and automatic transmissions.
Working principle:
*DSG uses two clutches: one for odd gears (1, 3, 5, etc.) and one for even gears (2, 4, 6, etc.).
* When the car is in one gear, the next clutch prepares the other gear in advance.
* When changing gears, one clutch is disengaged and the other is connected at the same time, which ensures smooth and fast shifting without interruption of traction.
DSG advantages:
* Fast Gear Shifts: Using dual clutch technology, the DSG changes gears faster than traditional automatic transmissions.
* Smooth shifting: Gear shifts occur smoothly and without jerking, providing a comfortable driving experience.
* Fuel economy: DSG helps reduce fuel consumption by optimizing gear shift points and minimizing power loss.
* High dynamic performance: The fast shifting of the DSG allows the car to accelerate faster and provides better maneuverability.
*Sport mode: Some DSG transmissions have a sport mode that allows the driver to select gears themselves and use the steering wheel paddle shifters.
DSG Limitations:
*Complexity: DSG is a more complex gearbox compared to manual or traditional automatic transmissions.
*Cost: DSG is more expensive to produce than other types of gearboxes.
*Maintenance: The DSG requires regular maintenance, including oil and filter changes.
DSG has become a popular choice for many Volkswagen, Audi, Koda and SEAT car models. It provides a combination of high performance, fuel economy and comfortable driving.
