Planetary gears work as they are called: in the middle is the sun gear, which is driven by the engine. It transmits its movement to three revolving planet wheels that form a step. They are arranged on the bearing pin of a planet carrier. Each of the last planetary carrier is firmly connected to the output shaft and thus ensures the power transmission at the output. Outside, the planet gears run in a gear housing with internal teeth, the so-called ring gear.
