Disclosed is a vehicle coupler, which comprises a coupler body, a coupler tongue, a coupler tongue push iron, a coupler lock, a lower lock pin assembly and an unlocking device. The bearing surface of the tail part of the coupler tongue is 24 mm in thickness; the connecting part between the coupler shoulder and the coupler body is 22 mm in wall thickness on both sides; the weight reduction hole of a coupler wrist is 19 mm in wall thickness; the coupler is provided with an anti-missing device; a coupler lifting rod and the lower lock pin assembly of the unlocking device are indirectly connected through a lower lock pin rotation shaft. The coupler has the advantages of light weight, simple structure, convenient overhaul, small abrasion, strong anti-missing function; and tallies with the principle of intensity matching, that is, combining the present situation that the existing 70t level truck is equipped with a 17-type coupler; the intensity of the coupler is equal to the 17-type coupler, namely, the minimum destructive load of the coupler tongue is 3430KN and that of the coupler body is 4005KN; meanwhile, the coupler is in conformity with the exchangeable principle, that is, the coupling can be exchanged with a 17-type coupler or an F-type coupler and matches with the cushion device of the existing 70t level truck coupler, to insure the exchangeability of the system and improve the standardized degree of the product.
