The Magic of The Planetary Gearbox: How do automatic transmissions work?

#howitworks #gearbox #carmaintenance #carlover How Does The Planetary Gearbox work? The principle of operation of an automatic transmission is based on a planetary gear. The planetary gear device is three wheels: the central one is called the sun gear, the outer one is the crown gear, and the gears that rotate around the sun gear are called satellites - translated into Russian it means satellites. It turns out that the planetary gear is so called because the movement trajectory of the satellites resembles the movement of the planets around the sun - very deep meaning! There are three modes of operation of the planetary gear within the axle, in each of these modes one of the three elements (sun gear, driver or crown gear) is stopped - this affects the nature and speed of rotation of the other elements.
