A torsion beam of a coupled torsion beam axle may include an external beam having a first cross-section in which an external protrusion of a middle end portion of the external beam is formed to protrude toward upward in a longitudinal direction of the external beam, and external skirt portions are vertically extended along the longitudinal direction at both end portions of the external protrusion; and an internal beam having a second cross-section in which an internal protrusion of a middle end portion in the internal beam is inserted into the external beam to face the external protrusion of the external beam, and internal skirt portions are extended in a vertical direction at both end portions of the internal protrusion, and each external surface of the internal skirt portions and each internal surface of the external skirt portions are surface-bonded in a mutually matched state. A gap is formed between an external surface of the internal protrusion and an internal surface of the external protrusion to form a closed cross-section.
本发明涉及一种耦合式扭力梁车桥的扭力梁,其可以包括:外梁,所述外梁具有其中所述外梁的端部部分的中间部的外突出部形成为在所述外梁的纵向方向上朝向上方突出的第一截面,并且外裙部在所述外突出部的两个端部部分处沿着纵向方向竖直延伸;以及内梁,其具有其中所述内梁中的端部部分的中间部的内突出部插入到所述外梁中以面对所述外梁的所述外突出部的第二截面,并且内裙部在所述内突出部的两个端部部分处竖直延伸,并且所述内裙部的每个外表面和所述外裙部的每个内表面以相互匹配的状态表面结合。在所述内突出部的外表面与所述外突出部的内表面之间形成有间隙,以形成闭合截面。
