The invention relates to a truck frame assembly, which belongs to the technical field of automobile manufacturing, and comprises a left longitudinal beam, a right longitudinal beam, a plurality of cross beams connected between the left longitudinal beam and the right longitudinal beam, and a plurality of standard holes arranged on the ventral surfaces of the left longitudinal beam and the right longitudinal beam side by side at equal intervals, standard holes are formed in the cross beam connecting plate at the same interval as the standard holes in the longitudinal beams, the cross beam connecting plate is connected with the longitudinal beams through bolts and rivets, and a tail beam is installed between the tail ends of the left longitudinal beam and the right longitudinal beam and connected with the longitudinal beams through bolts and rivets. The specifications of frame standard parts are unified, the production efficiency and the assembly efficiency of the frame assembly are remarkably improved, free combination and free arrangement of the cross beams and chassis connecting accessories on frames with different axle distances and different heights are achieved through the design scheme of the standard holes, special parts do not need to be newly produced, and the platform design of the frame assembly is achieved.

    本发明涉及一种载货车车架总成,属于汽车制造技术领域,包括左纵梁、右纵梁以及连接在左纵梁与右纵梁之间的若干横梁,左纵梁、右纵梁腹面上并排等距设有的多个标准孔,横梁采用钢管制成,称为管横梁,管横梁两端焊接有横梁连接板,横梁连接板上开设有与纵梁上标准孔设置间距相同的标准孔,横梁连接板与纵梁通过螺栓、铆钉相连,左纵梁、右纵梁尾端之间安装有尾梁,尾梁通过螺栓、铆钉与纵梁相连。车架标准件规格得到统一,显著提升车架总成的生产效率和组装效率,标准孔设计方案实现了横梁和底盘连接附件在不同轴距、不同高度的车架上自由组合和自由布置,而无需新出专用件,实现车架总成平台化设计。
