Abstract: Provided in the present disclosure are a coupler and a vehicle with the coupler. The coupler includes: a coupler body, having an accommodating cavity, a first impact protection pin flange being disposed on the coupler body; and a coupler tongue, pivotally connected to the coupler body. The coupler tongue includes a head portion and a tail portion. The tail portion is positioned inside the accommodating cavity, and a first interval d is formed between an end surface of the tail portion and the coupler body. The coupler tongue further includes a second impact protection pin flange, and a second interval b is formed between the first impact protection pin flange and the second impact protection pin flange, wherein the first interval d and the second interval b satisfy: d<b.

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.

Abstract: A railway vehicle, a coupler, and a coupler body thereof. The coupler body comprises an upper traction platform, a lower traction platform, a lock chamber, and a pin hole. A traction surface of an upper traction platform and/or a lower traction platform is divided into a contact area and a yielding area along the direction approaching the lock chamber, an extension face of the end of the contact area close to the lock chamber is an M2 face, and the yielding area is positioned at the side of the M2 face close to the pin hole. The yielding area is positioned on the side of the contact area next to the lock chamber and there is a gap and no contact between the yielding area and a traction platform of a coupler knuckle.
