The invention discloses a bearing type micro truck body rear suspension structure meeting the heavy load requirement, and belongs to the field of automobile manufacturing. The rear suspension structure of the micro truck body comprises two longitudinal beams arranged in a spaced mode and a first cross beam fixed between the two longitudinal beams, box-shaped supporting structures are fixed to the tops of the longitudinal beams, a second cross beam is fixed between one ends of the tops of the two box-shaped supporting structures, and each box-shaped supporting structure comprises an inverted-U-shaped top plate; an inner flanging side plate and an outer flanging side plate are fixed to the two ends of the bottom of the inverted-U-shaped top plate, a U-shaped bottom plate is fixed to the bottoms of the inner flanging side plate and the outer flanging side plate, the U-shaped bottom plate is fixed to the top of the longitudinal beam, an n-shaped rear cover assembly is fixed to the end, away from the second cross beam, of the box-shaped supporting structure, and the bottom of the n-shaped rear cover assembly is fixed to the top of the longitudinal beam. The rear suspension structure is realized by adopting an upper, middle and lower three-layer overlapped structure, so that the torsional rigidity and the bending rigidity of the rear suspension are controlled and improved, and the requirement that the loading of the whole vehicle is greater than 1.5 tons is met.

    本发明公开一种满足重载要求的承载式微卡车身后悬结构,属于汽车制造领域。该微卡车身后悬结构包括两根间隔设置的纵梁和固定在两根纵梁之间的第一横梁,纵梁顶部均固定有盒形支撑结构,两个盒形支撑结构的顶部一端之间固定有第二横梁,盒形支撑结构包括倒U形顶板,倒U形顶板的底部两端固定有内翻边侧板和外翻边侧板,内翻边侧板和外翻边侧板的底部固定有U字形底板,U字形底板固定于纵梁的顶部,盒形支撑结构远离第二横梁的一端固定有几字形后盖组件,几字形后盖组件的底部固定于纵梁的顶部。本发明采用上中下三层叠拼的结构实现,从而控制并提高后悬处的扭转刚度和弯曲刚度,满足整车装载大于1.5吨的需求。
