    Abstract: The invention relates to a hollow-bodied component consisting of at least two die-cast shell elements (1, 2), which is suitable in particular for use as a steering component in motor vehicle running-gear assemblies. Said hollow-bodied component is characterised in that at least one respective connection zone (5, 6, 18, 19) is configured on the shell elements (1, 2) to be interconnected, one connection zone (5) consisting of at least one first contact area (7) with an essentially U-shaped cross-section that is located on the respective shell element (1) and the second connection zone consisting of at least one strut-type second contact area (8) that engages in the space in the U-shaped first contact area (7) and that is located on the respective other shell element (2). The connection zones (5, 6, 18, 19) are joined in a force fit in a cold welding process that uses a contact pressure (F1, F2), whose value is a multiple of the separating force components (Fr) that act on the connection zones (5, 6, 18, 19) during operation. The invention also relates to a method for producing a hollow-bodied component. The special configuration of the connection zones (5, 6) in conjunction with the cold welding in said zones permits the production of a cost-effective component, which, in contrast to prior art, has a reduced weight by a special adaptation of the wall thicknesses achieved in the aluminium die-casting process.

    Abstract translation: 本发明涉及一种由至少两个压铸壳元件（1,2）组成的中空体部件，其特别适用于机动车行驶齿轮组件中的转向部件。 所述中空体部件的特征在于，至少一个相应的连接区域（5,6,18,19）构造在壳体元件（1,2）上以互连，一个连接区域（5）由至少一个 第一接触区域（7），其具有位于相应壳体元件（1）上的基本上为U形的横截面，并且所述第二连接区域由至少一个支撑型第二接触区域（8）组成，所述第二接触区域 在U形的第一接触区域（7）中并且位于相应的另一壳体元件（2）上。 连接区域（5,6,18,19）以与焊接过程中的接合压力（F1，F2）的力合并在一起，该接触压力值是作用于分离力分量（Fr）的倍数的接触压力 连接区域（5,6,18,19）。 本发明还涉及中空体成分的制造方法。 连接区域（5,6）与所述区域中的冷焊连接的特殊构造允许生产成本有效的部件，其与现有技术相比具有通过壁的特别适配而减小的重量 在铝压铸工艺中获得的厚度。
