Abstract: A locking apparatus, a powertrain, a power transmission system, and a vehicle, the locking system (200) comprising: a first flange (201a) and a second flange (201b); and first and second flange locking structures (Q1, Q2), the first and second flange locking structures (Q1, Q2) both being used for selectively locking the first flange (201a) and the second flange (201b) in order to make the second flange (201b) rotate synchronously with the first flange (201a), or in order to make the first flange (201a) rotate synchronously with the second flange (201b); the first and second flange locking structures (Q1, Q2) both comprise: a synchronising ring (202), the synchronising ring (202) being constantly connected to the corresponding flange in order to rotate synchronously with the corresponding flange, and the synchronising ring (202) being able to slide relative to the corresponding flange; and a drive assembly (203), the drive assembly (203) being capable of selectively pushing the synchronising ring to slide along the axial direction of the corresponding flange from an unlocked position to a locked position; when a synchronising ring (202) is positioned in the locked position, the two synchronising rings are connected, such that the other flange rotates synchronously with the flange corresponding to said synchronising ring. The present locking apparatus can implement a bidirectional locking function, and has a simple structure.
