Gearbox can be preselected at any time for the next gear and ready for shift up, so the biggest advantage of double clutch gearbox is fast shift speed. Usually the odd-numbered gear (first, third, etc.) is on one input shaft, while the even-numbered gear is on the other shaft, and the two axles are sheathed together (red and green below). The difference is that the shift fork is not driven by the driver through the gearbox shifter, but is controlled by the gearbox or the powertrain electronic control module (ECM), which replaces the driver's brain with a computer. Like a manual transmission, the dry DCT has a synchronizer and a shift fork. The two clutches are located on separate shafts that can be engaged and detached separately. In fact, DCT dual-clutch transmissions have more in common with manual transmissions than traditional AT automatic transmissions.Īs the name suggests, a dual clutch transmission has two clutch assemblies and two input shafts. In the basic classification, AT and DCT are automatic gearboxes, that is, automatic shift, the driver does not need to step on the clutch pedal, just need to put the gear knob in the right position to automatically change gear. Today, we will analyze the difference between AT automatic gearbox and DCT double clutch gearbox from the technical aspect, to see if double clutch is worth choosing. So why do cars with dry double-clutch have many problems and poor driving experience? The main brands are Volkswagen and GAC Trumpchi, both of which use dry double-clutch gearboxes.
