DRIVETRAIN ARRANGEMENT HAVING A DECOUPLING UNIT FOR DECOUPLING AN INPUT SHAFT FROM AN OUTPUT SHAFT

摘要

The invention relates to a drivetrain arrangement having a decoupling unit for decoupling an input shaft of the drivetrain arrangement from an output shaft of the drivetrain arrangement. The decoupling unit comprises a planetary gear system having three elements in the form of a sun gear, a ring gear and a planet carrier arrangement having a plurality of planet gears, via which planet gears the sun gear is drivingly coupled to the ring gear, wherein a first element of the three elements is drivingly connected to the input shaft and a second element of the three elements is drivingly connected to the first input shaft. A pawl is also provided, which is mounted on a fixed component so as to pivot about an axis extending in parallel with the input and output shafts between a locking position and an unlocking position, wherein the pawl rigidly connects at least part of the third element to the fixed component in the locking position, whereas the third element is rotatable with respect to the fixed component in the unlocking position of the pawl.
