An important part of any car is the gearbox.

In this appendix you will find the description, the device and the operation principle of the automatic transmission.

Internal combustion engines are not capable of driving the car in different modes without special devices that change the crankshaft speed. On the vehicles part, automatic transmissions are used for this. The use of automatic transmission allows to reduce the number of traffic control devices and to simplify its driving.

 Recently, a fairly large number of cars with automated, and, more precisely, robotic control of mechanical gearboxes, have appeared. The general device of the automatic transmission and the principle of its operation differ significantly from these devices.

From a purely technical point of view, automatic can be considered any gearbox, the control of which does not require intervention from the driver.

 The only exception is the variators, in which the change in the number of revolutions occurs steplessly (there are no fixed transmissions), and therefore smoothly and without the slightest jerking. Therefore, the variators can not be referred to gearboxes.

It is in this mechanism of automatic transmission and there is a change in the transmission ratio of the speed of the input shaft. Together with the torque converter this mechanism forms an automatic transmission.
