Planetary gear arrangement for internal combustion engine of motor car, has movable coupling element placed between pulley and planetary gear, where pulley is coupled with sun wheel or ring gear in respective coupling state

摘要

The arrangement has a sun wheel (18) and a ring gear (22) that are rotated around a rotational axis, where a planetary gear (20) is arranged between the sun wheel and the ring gear. Planet carriers (38, 24) are rotated around the rotational axis and coupled with one another. A movable coupling element is placed between a pulley (32) and another planetary gear (12). The pulley is coupled with the sun wheel or the ring gear in a first coupling state. The pulley is decoupled from the sun wheel in a second coupling state and coupled with the planet carriers in a third coupling state.
