The invention discloses a coupler draft-gear, which comprises couplers and draft-gears. The coupler draft-gear is characterized in that the draft-gears are arranged at the bottoms of the two ends of a carriage along the width direction of the carriage, the couplers are arranged at the bottoms of the two ends of the carriage along a central axis of the carriage, the draft-gears are located on the left side or right side of the central axis of the carriage, a limited pushing mechanism is arranged between the coupler and the draft-gear, and the limited pushing mechanism can push the coupler to move along the central axis of the carriage and can push the draft-gear to be compressed along the width direction of the carriage. According to the coupler draft-gear disclosed by the invention, on the premise of not changing the maximum stroke and maximum resistance of the coupler, the capacity of the draft-gear is improved, and then the impact speed of the carriage is improved, so that when a train is running in limited operating conditions in the process of traction or braking, the draft-gear still can maintain a good cushioning effect, thereby improving the stationarity and safety of the train in the process of running.
