The invention relates to a method for producing a rack bar (3) for a steering gear of a motor vehicle, said rack bar having a longitudinal axis (L) extending in the longitudinal axial direction and having at least two axially extending tooth sections (31, 32), each having a tooth, the tooth sections (31, 32) being connected to one another in the axial direction by means of a connecting section (33), and are torsionally arranged relative to each other with a defined angular offset with respect to a rotation about the longitudinal axis (L). In order to be able to achieve a small production effort, the invention proposes the following steps: providing a one-piece blank (301), generating the two tooth sections (31, 32) on the blank (301) in a substantially oriented manner relative to one another, twisting the tooth sections (31, 32) relative to one another about the longitudinal axis (L), and forming the tooth sections (31, 32) on the blank (301). Wherein said connecting section (33) is plastically twisted to produce said angular offset

    本发明涉及一种用于机动车的转向传动装置的齿杆(3)的制造方法,所述齿杆具有沿纵向轴向延伸的纵轴线(L),并且所述齿杆具有至少两个轴向延伸的齿部区段(31、32),所述齿部区段分别具有齿部,其中所述齿部区段(31、32)在轴向上经由连接区段(33)彼此连接,并且关于绕所述纵轴线(L)的旋转以定义的角度偏移相对于彼此扭转地设置。为了能够实现较小的制造耗费,本发明提出如下步骤:‑提供一件式的坯件(301),‑在所述坯件(301)上相对于彼此以基本定向产生所述两个齿部区段(31、32),使所述齿部区段(31、32)相对于彼此围绕所述纵轴线(L)扭转,其中所述连接区段(33)被塑性扭曲以产生所述角度偏移
