A trailer carriage comprises two longitudinal beams, a plurality of cross beams and a suspension system. The two ends of the cross beams are welded and fixed to the two longitudinal beams correspondingly, and the multiple cross beams are arranged in the length direction of the longitudinal beams. The longitudinal beam comprises a web, an upper wing plate formed by bending the top of the web towards the outer side and a lower wing plate formed by bending the bottom of the web towards the inner side, a first welding face is formed on the lower surface of the upper wing plate, and a second welding face is formed on the outer side face of the web. The suspension system comprises a support, the top end face of the support abuts against the first welding face and is fixedly welded to the first welding face, and the inner side face of the support abuts against the second welding face and is fixedly welded to the second welding face. Good connection strength between the support and the longitudinal beam is guaranteed, meanwhile, the gravity center of the trailer frame is lowered, and the driving performance of a trailer is improved.

    一种挂车滑架,包括两根纵梁、若干横梁、悬挂系统;横梁的两端分别焊接固定在两根纵梁上,且若干横梁沿纵梁的长度方向排列;纵梁包括腹板、由腹板的顶部向外侧弯折形成的上翼板、由腹板的底部向内侧弯折形成的下翼板,上翼板的下表面形成第一焊接面、腹板的外侧面形成第二焊接面;悬挂系统包括支架,支架的顶端面贴靠于第一焊接面并与第一焊接面焊接固定、支架的内侧面贴靠于第二焊接面并与第二焊接面焊接固定。本发明确保支架与纵梁之间具有较佳的连接强度,同时,降低了挂车车架的重心,提升了挂车的行驶性能。
