Dual-Clutch Transmission

If you ask any random person about types of transmissions available, he is more likely to tell you that one is the usual manual gearbox, where the driver changes the gears and the second one being the automatic gearbox where all you have to do is simply put the gear stick in D mode and squeeze the accelerator. Dual-Clutch Transmission is something that not many people are aware about or aren’t bothered.


 

But now more and more automatic transmission cars are coming with the Dual-Clutch Gearbox, reason being faster gear changes and better fuel efficiency. A Dual-Clutch Gearbox is something very normal with racing cars. Once again the primary reason being faster gear changes that is obviously required for the race-car in the middle of a race.


 

In a Manual gearbox, when the driver changes from one gear to another, he sinks in the clutch pedal which moves the clutch disconnecting the power from the engine to the gearbox, while also shifting the gear lever to shift it to the other gear, this moves a belt from one different sized gear to the other, now when the driver has shifted the lever and releases the clutch pedal, the other gear is synchronized with again re-engaging connection with the engine in order to start receiving the power for the wheel to move.


 

In a Dual-Clutch Transmission, there are basically two clutches without an actual clutch pedal. Smart computerized electronics manage the clutches in order for the gearbox to continue shifting gears to manage power to the wheels, just like in the usual automatic transmission. But the catch in Dual-Clutch gearbox is that the flow of power is uninterrupted unlike the manual transmission where the clutch breaks off from the engine in order to the gears to shift, also the two clutches operate on their own. One clutch controls the odd numbered and reverse gear while the other operates even numbered ones.


In simple terms, why Dual-Clutch is better is because, it can select the next gear even before the current gear is released, which means no interruption in power to the gearbox.
