A carriage assembly of a trailer comprises two longitudinal beams, a plurality of cross beams and a suspension system. The longitudinal beam comprises a side wall, a top wall located at the top of the side wall and a bottom wall located at the bottom of the side wall, an opening is formed between the top wall and the bottom wall and located on the inner side of the longitudinal beam, and the end of the cross beam penetrates through the opening; the end surface of the cross beam is fixedly connected with the inner surface of the side wall; the upper surface of the cross beam is fixedly connected with the lower surface of the top wall; the lower surface of the cross beam is fixedly connected with the upper surface of the bottom wall; the suspension system comprises a support, the support comprises an outer wall plate, an inner wall plate and a connecting piece connected between the outer wall plate and the inner wall plate, the top of the outer wall plate is attached to the outer surface of the side wall and connected with the side wall, the top of the inner wall plate is connected to the longitudinal beam, and supporting plates formed by bending in the direction away from the outer wall plate are arranged on the two sides of the inner wall plate correspondingly. The supporting plate is connected to the cross beam. The transverse rigidity of the joint of the support and the longitudinal beam is increased, it is guaranteed that the vehicle has the good driving performance, and the safety of the vehicle is improved.
