    Abstract: The present invention discloses a locking device, a power assembly, a power transmission system and a vehicle. The locking device includes: a first flange and a second flange; and first and second flange locking structures, the first and second flange locking structures each being used for selectively locking the first flange and the second flange to be adapted to rotate the second flange synchronously with the first flange or adapted to rotate the first flange synchronously with the second flange; wherein the first and second flange locking structures each include: a synchronizing ring, the synchronizing ring being normally connected to the corresponding flange to be adapted to rotate synchronously with the corresponding flange, and the synchronizing ring being slidable relative to the corresponding flange; and a driving component, the driving component selectively pushing the synchronizing ring to slide from an unlocked position to a locked position in an axial direction of the corresponding flange, wherein when the synchronizing ring is in the locked position, the two synchronizing rings are connected to be adapted to rotate the other flange synchronously with the flange corresponding to the synchronizing ring. The locking device according to embodiments of the present invention can realize the two-way locking function, and is simple in structure.
