The invention relates to a portal axle and to a method for producing a portal axle for a rail vehicle, comprising the following molded components: a shaft central part (2) extending along a longitudinal axis (L-L) and two journals (10, 11, 12), 10 '), one of which is located on a first end section (6) of the shaft middle part (2) and the second one is located on a second end section (7) of the shaft middle part (2), which end section is formed opposite the first end section (6), the shaft journals (10, 11) being oriented outwardly away from the shaft middle part (2) and, in use, forming a bearing for rotatably supporting the respective shaft journal (10, 11). 11) of the track wheel. The portal axle according to the invention has optimized use characteristics while minimizing the weight. According to the invention, a longitudinal opening (12, 13, 18, 19, 12 ') extending in the longitudinal direction of the portal axle (1) is formed in at least one of the forming assemblies (2, 10, 11, 10'). The invention also relates to a method for producing such an axle.
本发明涉及一种门式车桥和一种用于制造用于轨道车辆的门式车桥的方法,所述门式车桥具有以下成型组件:沿纵轴线(L‑L)延伸的轴中间部分(2)和两个轴颈(10,11,10’),其中一个轴颈位于轴中间部分(2)的第一端部区段(6)上,并且第二个轴颈位于轴中间部分(2)的与第一端部区段(6)对置地构造的第二端部区段(7)上,其中,所述轴颈(10,11)向外远离轴中间部分(2)地定向,并且在使用中形成用于能够转动地支承在相应的轴颈(10,11)上的轨道车轮的转动轴线。根据本发明的门式车桥在重量最小化的情况下具有优化的使用特性。其实现方式是在所述成型组件(2,10,11,10’)中的至少一个中成型在所述门式车桥(1)的纵向方向上延伸的纵向开口(12,13,18,19,12’)。本发明还提供一种用于制造这样的车桥的方法。
