Abstract
A vehicle coupler, a coupler tongue and a coupler body. Upper traction platforms and lower traction platforms of the coupler tongue and the hook body are arranged in an offset manner in the horizontal direction, and the section R of a traction surface of the upper traction platform and the section S of a traction surface of the lower traction platform are obtained by sectioning the coupler tongue along any vertical surface across an axis of a pin hole; and the perpendicular distance between the point on the section R closest to a nock portion and the axis of the pin hole is k, and the perpendicular distance between the point on the section S closest to the neck portion and the axis of the pin hole is m, and as such, n=|k−m|, and 10 mm≤n≤125 mm.
