The invention relates to a method for producing a toothed rack (3, 6) for a steering gear (2) of a motor vehicle, said toothed rack having a tubular hollow profile extending axially in the longitudinal direction of a longitudinal axis (L), said hollow profile having an axially extending toothing section (31) with toothing, wherein a hollow cylindrical tube section (4) is provided having a given wall thickness (B) that is uniform in the circumferential direction, into which hollow cylindrical tube section the toothing (32) is introduced. In order to achieve a degree of freedom of design for the extension of the toothing with reasonable production, the invention proposes that-a flattened section (41) with an increase in wall thickness (W) is produced by means of local plastic forming,-the toothing (32) is produced in the region of the increase in wall thickness (W). A rack is also the subject of the invention.

    本发明涉及一种制造用于机动车的转向传动器(2)的齿条(3,6)的方法,所述齿条具有在纵轴线(L)的纵向方向上轴向延伸的管状空心型材,所述空心型材具有带有齿部的轴向延伸的齿部区段(31),其中提供了具有给定的、在周向上均匀的壁厚(B)的空心圆柱形管区段(4),所述齿部(32)被引入到所述空心圆柱形管区段中。为了在合理制造的情况下实现齿部扩展的设计自由度,本发明提出,‑通过局部塑性成形产生具有壁厚增大(W)的展平部(41),‑在壁厚增大(W)的区域中生产齿部(32)。齿条同样是本发明的主题。
