摘要： 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.

摘要： The present invention discloses a locking device, a power assembly, a power transmission system and a vehicle. The locking device includes: a first flange, the first flange being adapted to be fixed on the first shaft; a second flange, the second flange being adapted to be fixed on the second shaft; a synchronizing ring, the synchronizing ring being normally connected to the first flange to be adapted to rotate synchronously with the first flange, and the synchronizing ring being slidable relative to the first 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 first flange. When the synchronizing ring is in the locked position, the synchronizing ring is connected to the second flange be adapted to rotate the second flange synchronously with the first flange. When the synchronizing ring is in the unlocked position, the synchronizing ring is separated from the second flange. The locking device according to embodiments of the present invention can realize the single-way locking function, and is simple in structure.
