摘要： The twist-beam axle (10) comprises a central cross-member (11) compliant to torsion and a pair of trailing arms (12) fixed to side end portions (11a) of the cross-member (11) for articulated connection of the axle to the vehicle body and for support of the rear wheels. Each trailing arm (12) is formed by a pair of first, transversely inner half-shells (18, 19), that is, a front half-shell and a rear half-shell, respectively, securely connected to each other and to the respective end (11a) of the cross-member (11), and by a second transversely outer half-shell (20), securely connected to the pair of first half-shells (18, 19) so as to form therewith a structure having a closed cross-section.

摘要： A cross-member for a motor-vehicle twist-beam axle suspension includes a single piece of steel that defines a closed cross-section and integrally forms a middle section, a pair of end sections, and a pair of joining sections. The middle section has a center axis extending along a curvilinear path lying in a first plane and a squashed portion extending in a second plane inclined to the first plane. The end sections are adapted to be securely connected to respective trailing arms of the twist-beam axle suspension. Each of the joining sections is interposed between the middle section and the respective end section and defines an opposite concavity with respect to the middle section. A twist-beam axle suspension for a motor vehicle includes the cross-member and a pair of trailing arms. A method produces the cross-member for a motor-vehicle twist-beam axle suspension.

摘要翻译： 用于机动车辆扭梁轴悬架的横梁包括限定封闭横截面并且一体地形成中间部分，一对端部和一对连接部分的单块钢。 中间部分具有沿着位于第一平面中的曲线路径延伸的中心轴线和在与第一平面倾斜的第二平面中延伸的挤压部分。 端部适于牢固地连接到扭梁轴悬架的相应拖臂上。 每个接合部分介于中间部分和相应端部之间，并且相对于中间部分限定相对的凹部。 用于机动车辆的扭梁悬架包括横梁和一对牵引臂。 一种方法产生用于机动车辆扭梁轴悬架的横梁。
