Everything To Know About Dual-Clutch Automatic Transmissions
Highlights
- Transmission systems were introduced to the world in 1939.
- Did you know manual transmissions save fuel for car owners?
- Manual transmissions need special certifications
One of the major concerns with transmission systems was that manual intervention was tiresome for drivers. That led to manufacturers looking for ways to reduce human shifts and introduce automatic transmission systems. One such transmission system making waves is the dual-clutch automatic transmission system. The push for tweaks in traditional automatic transmissions had led to manufacturers relying on this system. Let us find out more about this!
What is a dual clutch automatic transmission system?
The DCT or dual-clutch automatic transmission system is being pushed to replace traditional automatic transmission systems. There are two shafts with their clutches – one for even gears and one for odd gears. The driver's gear is pre-selected, which makes driving easier for the person. The shifts are a bit jerky at low speeds, but DCTs have been used in high-performance vehicles. The cars that contain DCT include Volkswagen's DSG, Porsche's PDK, Audi's S Tronic, and Ford's Powershift.
How do DCTs work?
The dual-clutch system works with two clutches, as the name suggests. These clutches are controlled by a network of electronic modules and hydraulic systems that eliminates the need for the clutch pedal. The clutches are not co-dependent. One of the clutches works with the odd gear numbers, and the other works with even gear numbers. The power flow between the engine and the transmission system is not interrupted, and the car can shift gears smoothly.
Advantages of dual-clutch automatic transmission
There are several reasons as to why the industry has been relying upon DCTs:
- DCTs provide much better fuel economy as opposed to automatic transmission systems.
- They are much smoother as opposed to AMTs or manual transmissions.
- Performance driving is where DCTs find maximum application since the gear shifting is smooth and precise.
- DCTs have been shown to provide major savings during their lifetime.
Disadvantages of dual-clutch automatic transmissions
Like any other transmission system in the market, there are downfalls to DCTs as well, which include:
- The major issue is getting used to DCTs if the driver uses manual transmissions or is just starting. At lower speeds, the car often feels jerky, which affects smooth traveling.
- The space that DCTs take is much more than other forms of transmissions, which means more space is required to accommodate DCTs.
- DCTs, once damaged, could be an expensive affair. The parts are costly, and special training is needed.
If DCTs are compared to other forms of transmissions in the market, it is clear that they have a more significant advantage over others. If the downfalls can be navigated, they are the best option for automatic transmissions in the market.
