The latest generations of cars can install both mechanical and automatic transmission. Besides, it's not that rare steel machines with variable speed. If the mechanics is all relatively clear, as is the case with the last two? But because when buying a new or used car before the buyer gets a legitimate question: the variable-speed or automatic – which is better? Before to answer, it is necessary to further clarify one thing. Namely, what is the difference between carton machine from the variator.
Auto-box
Automatic transmission (a / t) created in the early XX century, and its original application she found in shipbuilding. Its inventor, German scientist considered to be Fettinger, who proposed a hydrodynamic transmission, unleashed the engine and the propeller.
Later, in the forties of the last century, American automakers box automatic Hydramatuc were installed in Oldsmobile cars. Since the design of the transmission, consisting of two main components (torque Converter and the gearbox), not much has changed – only improved. The torque Converter replacing the clutch allows you to shift gears smoothly, without jerks, and the reducer, consisting of several pairs of gears, makes it possible to change the gear ratio. Before finding the answer to the question: the variable-speed or automatic – which is better, should weigh the strengths and weaknesses of each type.
Advantages of automatic transmissions:
Disadvantages of automatic transmissions:
CVT
- Rooted opinion that the CVT was invented later, the automatic transmission is a big misconception. The principle of its operation was described by a famous Leonardo Da Vinci in the XV century, only to introduce it failed recently – during the second half of the twentieth century.
Stepless variator can be called one of the varieties of automatic transmission. He has no speed. Structurally, the variator consists of two pulleys (driving and driven) located opposite one another and United by the trapezoidal belt. Cones variator have halves, pinching and spreading which changes the torque from the driving pulley to the driven.
The Principle of operation of a technical device here is definitely easier and more functional. But it would be wrong to assert unequivocally that if the opportunity to choose CVT or automatic, which is better to purchase the CVT. Despite its advantages, it is also not without drawbacks.

Disadvantages of CVT:
In conclusion
So, the CVT or automatic - which is better? Judging by technical characteristics, the dynamic characteristics of the CVT, of course, better than automatic transmission. Plus – smooth gear shifting and lower fuel consumption. However, the machine is much easier and cheaper to fix. Although, if you purchase a brand new car, covered by warranty, you can choose the CVT. In any case, a definite answer to the question: which is better – the CVT or automatic, perhaps can not give one, but because the final choice entirely depends on you.
