What is a variator?

Very often you hear that this car uses a variator, or reading car magazines, you stop to look at this interesting word, in the column "vehicle specifications".Everybody knows what a gearbox is, for what it's used, but that's what a CVT is, it's hard to answer. In this article we will try to answer this question.

Basic information about the variator

Let's start with the fact that the variator is a special device, perhaps somewhat similar to a conventional gearbox, but uses slightly different working parts. Let's look more closely at what a variator is in a car.

Imagine the acceleration of an electric car - it's a smooth, quiet move, you quickly gain speed without unnecessary movements. It is this main, essential feature of the variator in front of the conventional gearbox. The principle of the variator is based on a smooth, continuous change in the gear ratio, due to this you do not feel the sharpness when starting the car or switching gears.

That is your car, which is equipped with a variator, will never allow you to make trivial mistakes, for example: you will always smoothly move, as if on a hill and on level ground you will not stall, but still smoothly go.

There are several modifications or types, who is comfortable with the variator:

  • V-belt
  • Toroidal
  • Chain

These variators differ in only a few features, but they are the same. Quite an interesting aspect of the variator is that huge pulleys, scrolling is not a normal belt of dense fabric, but steel, recruited from the plates. Perhaps, thanks to this, we get the effect of the smoothness of the car.

Variator, this is a fairly reasonable mechanism. For example, if you try to drive to any hill in high gear, you will not get it because the variator will switch to a lower gear itself, no matter how you squeezed the gas pedal. It is clear that this is all designed for comfort and more control over the car, but there are some disadvantages of the variator, for example: the main disadvantage of this device is that the variator is installed only on low-power cars, and large, powerful cars have a classic mechanics or automatic.

So, we figured out what a variator is, how and where it is used in modern cars.
