Specifically, the coupler draft gear 10 includes a coupler 100, a coupler yoke 200, a yoke 300, a slave plate assembly 400 and a draft gear 500. As shown in fig. 1, a three-dimensional coordinate system O-xyz is established, defining the x-axis direction as the lateral direction (i.e., left-right direction), the y-axis direction as the longitudinal direction (i.e., front-back direction), and the z-axis direction as the vertical direction (i.e., up-down direction). The y-axis direction is the tractive force direction of the coupler.

The rear end of the coupler 100 is coupled to the front end of the yoke 300 by a coupler yoke key 200. Specifically, the tail end of the coupler 100 is provided with a first through hole 110, the front end of the coupler yoke 300 is provided with a second through hole 310 corresponding to the first through hole 110, and the front end surface of the coupler yoke 300 is further provided with an opening 320. When the coupler 100 is assembled with the yoke 300, the tail end of the coupler 100 extends into the yoke 300 through the opening 320, and the coupler yoke 200 is inserted into the first through hole 110 and the second through hole 310, so that the coupler 100 is assembled with the yoke 300.

The compression force transmission process is as follows: the coupler 100 → the slave plate 410 → the shock absorber 500, and the shock absorber 500 presses against the rear seat of the slave plate 410 in the draft sill, completing the transmission of the entire compression force.

The bottom of the plate-shaped portion 411 is formed with a first anti-slip portion, the wear plate 420 is provided with a second anti-slip portion, and the first anti-slip portion is matched with the second anti-slip portion to prevent the wear plate 420 and the slave plate 410 from vertically displacing.
