![]() ![]() ![]() This type of clutch would not work if gears were selected mechanically as they are in a manual transmission. Another difference from a manual transmission is the actual operation. While your active gear is in use, the second clutch is also predicting which gear will be next and pre-selecting it, essentially meaning two gears are always selected at any given time. Essentially, Two Gears Are Selected Simultaneously Using Shift Forks for Quick Transitions This way, operation can switch back and forth between the two with the non-active clutch pre-selecting the next necessary gear. We already know from the name that a dual clutch transmission uses two clutches – but how does that work? The two clutches operate concentrically, so that one sits inside the other with two input shafts. The difference from a manual transmission then is that a DCT uses two output shafts instead of one. Without the torque converter, a DCT instead shifts gears more similarly to a manual transmission. More mechanically, dual clutch transmissions don’t have a torque converter like a typical automatic transmission. So, the next time you go car shopping, don’t forget to look at the “transmission” section of the window sticker see what the car has, you might just be able to impress the salesperson with your newfound knowledge.The Dual Clutch Transmission (DCT) Sits in Between Automatic and Manual Wheel-mounted paddles or the shift lever on the center console. Shifting the DCT is typically done through steering Need for a third pedal and the smoothness of an automatic transmission, without It provides the quicker shifting of a manual gearbox without the In summary, the dual-clutch transmission offers the best ofīoth worlds. 2020 Porsche 718 Boxster | Porsche The best of both worlds The DCT, however, is connected directly to the engine, so there are fewer moving parts, which equates to better fuel economy figures. Regular automatics are connected to a torque converter, which is then connected to the engine. For reference, the human eye typically takes 100 ms to blink. For high-performance cars like some Audis, Porches, and even Volkswagens, shifting to the next gear smoothly and as quickly as possible provides the best performance.Īs such, the typical shift times for a dual-clutch transmissionĬan range from 8 milliseconds (ms) to 100 ms depending on the manufacturer andĪpplication. The main advantage of having a dual-clutch transmission is the speed in which it shifts. Transmissions have as many as 10 gears (or speeds) in them. You may have noticed as of late that regular automatic Ratios in a DCT, as most that you’ll find are 6 or maybe 7-speed dual-clutch Also, it’s tough for engineers to put more gear Manual transmission, it typically won’t shift as smooth as a traditional automatic While a dual-clutch transmission does shift smoother than a The result is the smoothness and easiness of an automatic transmission Transmission when shifting gears, so having two of them means that the system willĪutomatically have the next gear ready to engage when shifting up or down the That the clutch is a mechanical part that disconnects the engine from the OneĬlutch is for the even gears and the other is for the odd gears. The DCT uses two clutches to shift the gears automatically. This transition in shift times not only causes rougher driving dynamics, but it also creates a slight delay when shifting gears. When it comes to shifting the gears in that transmission, the driver steps on the clutch to disengage the gears and shift to the next gear (either higher or lower). Think of a regular manual transmission, which uses a single clutch operated by the driver. But for those who do, here is the easiest way to explain what this Trust us, the technical components of a car can get downrightĬonfusing to understand and we know that most people might not even care too ![]() But what is a dual-clutch transmission? A simple explanation Nowadays, you might notice that a lot of cars use a dual-clutch automatic transmission (DCT). And while it’s hard to keep all of the technical stuff in mind when looking at a multitude of cars, important parts like the transmission is a good thing to understand. When car shopping, it’s important to know everything you can about a car. ![]()
