What to choose: a variator or an automaton?

The majority of motorists even before buying a car, have already decided whether to choose a variator or an automaton, or, in general, prefer mechanics. However, sometimes at a choice there are difficulties. It is necessary to understand the question, which gearbox is better? It is important to note that the variator has appeared not so long ago, because of which its operational shortcomings are not known well enough. However, a stepless robotic transmission has a lot of advantages.

As advantages of an automatic transmission it is possible to name the reduced expense of fuel, an accessible price of transmission, cheapness of maintenance service. As a disadvantage, low speed and smoothness of switching are usually identified.

Robotic transmission is considered the most successful solution. It is installed in the BMW M-series. It is based on a six-speed gearbox, where hydraulically switched and clutch systems are disabled.

As advantages of the variator, high smoothness and speed of switching, moderate fuel consumption are distinguished. The disadvantages are the high cost of the transmission system itself and the high cost of its subsequent maintenance.

Such a box is a stepless transmission system based on a very simple principle - the torque transmits the force to the rubber belt stretched over the conical discs, which makes it possible to form belt pulleys . When deciding, a variator or an automaton, it is important to know about the biggest drawback of the first one - the absence of a back and neutral gear. This may be a significant obstacle for some to choose.

Variator: the principle of operation

The variator is based on a transmission mechanism, whose function is to connect the wheels and the engine. It can also be equipped with a drive, which consists of a screw and a caterpillar. When working with a similar drive, a smooth transformation of the rotational speed of the discs of both the master and the slave is usually obtained. In many devices, such mechanisms have long been used.

When deciding whether a variator or an automaton should be chosen, it is worthwhile to know about the pros and cons of the first. Let's first talk about positive things. The car in which the variator is installed moves smoothly, without any jerking or jerking. As the speed increases, a slight noise appears, becoming louder. Such a car easily overtakes more powerful machines, which is associated with saving time, which usually goes to the switching speeds. When you lift this car will not roll back, and at the traffic lights do not stall.

Under all circumstances, cars with a variator start to move very smoothly, without loading the transmission. Driving is as comfortable as it has only two pedals.

For such vehicles, the sound of the engine is very smooth, with increasing speed, no loud sounds can be heard. All this became possible only thanks to special electronics, which stabilizes the load on the engine. We can say that a car with a variator has a lot of advantages, and the most important of them is fuel economy, as well as the possibility of a forced start.

However, such a gearbox has its drawbacks. Cars with engines of considerable power are not equipped with variators. The transmission must be filled with a special liquid, and then the one that was drained from another gearbox, as allowed in the case of an automatic box, does not fit. The operation of the variator is impossible without the use of multiple sensors, among which the pressure sensor, speed and others.

In general, when deciding what to choose, a variator or an automaton, you should rely first of all on whether you are ready to move to a fundamentally new principle of driving.
