The invention discloses a double-section crawler suspension truss structure, and relates to the technical field of engineering vehicles, in particular to a crawler suspension truss structure. The structure comprises a shield assembly, a left side suspension bracket and a right side suspension bracket, the left side vertically-arranged fixing hole assembly comprises fixing holes formed by welding two cylindrical steel plates, and the two fixing holes are of a vertical structure; a circular through hole is formed in the center of the shield assembly vertically; two ends of the shield assembly are welded with the left suspension bracket and the right suspension bracket; the inner ends of the left vertically-arranged fixing hole assembly and the right vertically-arranged fixing hole assembly are welded to the left end and the right end of the shield assembly correspondingly. The axes of through holes vertically formed in the left vertically-arranged fixing hole assembly, the right vertically-arranged fixing hole assembly and the shield assembly are the same. The problems that a center fixing hole of an existing crawler suspension truss torsion bar spring is of a geometric structure arranged front and back, and consequently the installation space and the damping performance of a crawler suspension truss structure are insufficient are solved.
一种双节履带车悬置桁架结构,涉及工程车辆技术领域,具体涉及一种履带车悬置桁架结。包括护罩总成、左侧悬挂支架和右侧悬挂支架;左侧上下布置固定孔总成包括两个圆柱钢板焊接形成的固定孔,两个固定孔为上下结构;护罩总成中心有圆形的上下设置的通孔;护罩总成两端与左侧悬挂支架和右侧悬挂支架焊接;左侧上下布置固定孔总成和右侧上下布置固定孔总成内端分别与护罩总成左右两端焊接;左侧上下布置固定孔总成、右侧上下布置固定孔总成和护罩总成内上下设置的通孔轴心相同。解决了现有履带车置桁架扭杆弹簧的中心固定孔采用前后布置的几何结构,而产生的履带车悬置桁架结构安装空间和减震性能的不足的问题。
