Description:
A Swing Drive Planetary Planet Gear is responsible for transferring power from the engine to the transmission. It consists of a set of gears arranged around a central sun gear. It is mounted on a carrier, allowing it to rotate independently and mesh with both the sun gear and an outer ring gear. As the engine drives the input shaft connected to the sun gear, the planet gears transmit torque to the ring gear, which is connected to the transmission input shaft.
