What are MT, AT, AMT, CVT, DCT? Who is better?

gearbox is one of the most important components of the automobile transmission system. It can adapt to different driving states by changing the transmission ratio according to different driving conditions, car speed and power, so as to achieve the best state of the car. So, what are the effects of different gearboxes on cars? What are the common gearboxes?

AT

AT is what we usually call automatic transmission. The automatic transmission is composed of hydraulic torque converter, control mechanism and other parts. The advantage of AT gearbox is that it can automatically shift and change torque according to the road conditions, it is convenient and quick to operate, and the driving comfort is high. The disadvantages are slow response to speed changes, uneconomical fuel consumption, complex mechanisms, and high repair costs.

MT

MT is a manual gearbox. The principle of a manual gearbox is to change the transmission ratio and drive torque to suit different car conditions. The advantages of manual gearboxes are that they can fully bring the driver's driving pleasure, low maintenance costs, relatively small fuel displacement, and more environmentally friendly. The disadvantage is that gear shifting is cumbersome and requires higher driving operability, and the frustration when shifting gears is more obvious.

AMT

AMT is also what we usually call a semi-automatic gearbox. The AMT gearbox is equipped with a set of electronically controlled hydraulic control system on the usual manual gearbox and clutch. Compared with the AT gearbox, the AMT gearbox has stronger power, lower fuel consumption, lower maintenance cost, and higher economy.

CVT

CVT is a continuously variable gearbox. As the name implies, the working principle of CVT transmission is to change the groove width of the driving wheel and the driven wheel through the hydraulic mechanism. Transmission ratio. Its advantages are the small size and light weight of the gearbox, smooth shifting, more comfortable without frustration, and better fuel economy. The disadvantage is that the transmission of parts and components is limited, and the manufacturing and maintenance costs are high.

DCT

DCT is the dual-clutch gearbox. As the name suggests, its working principle is controlled by two clutch gearboxes, one for odd gears and one for even gears. When the clutch responsible for odd-numbered gears is engaged in gear, the clutch responsible for even-numbered gears and the corresponding next gear are in the standby state, and the next gear can be engaged immediately after the current gear is separated, and the shifting speed is faster than normal transmission The box must be fast. The advantages are fast shifting speed, smooth connection and good fuel economy. The disadvantage is that the manufacturing cost is high, the heat generation is large, and the friction force is large.

Conclusion: Gearbox, as one of the greatest inventions in the automotive industry, is not only an excellent deputy for the engine’s power performance, but also fuel economy. Play a leading role. With the progress of society, more and more automobile manufacturers are constantly introducing new gearboxes to meet the needs of the public in the developing Galaxy, and more and more gearbox types appear in the public's field of vision.
