The invention discloses a vehicle coupler knuckle. The vehicle coupler knuckle comprises a coupler knuckle basal body, and the coupler knuckle basal body comprises a tail stopping part located at the tail of the coupler knuckle, a coupler knuckle inner wrist connected to the lower portion of the tail stopping part, a coupler knuckle pin hole located in the middle of the coupler knuckle and a coupler nose located at the pointed part of the coupler knuckle. A coupler knuckle inner cavity is formed between the tail stopping part and the coupler knuckle pin hole, a coupler knuckle S face is formed on the inner side of the coupler nose, the inner wall of the coupler knuckle inner wrist is a circular-ring curved surface a and is in transition connection with the inner wall e of the tail stopping part through a circular-ring curved surface b, the lower end of the inner wall of the coupler knuckle inner wrist is in transition connection with the inner side of the coupler knuckle S face through a circular-arc curved surface c, and the lower end of the inner side of the coupler knuckle S face is in transition connection with the coupler nose through a circular-arc curved surface d. The fatigue strength of the coupler knuckle can be obviously improved, the fatigue life of one side of the inner wrist face of the coupler knuckle S face is effectively prolonged, then the damage rate of the coupler knuckle is decreased, and the replacing frequency of a vehicle coupler is reduced.
