Description

车轴
技术领域
本发明涉及一种车轴，其作为一件式的铸件具有轴传动机构罩壳和一个或两个联接在轴传动机构罩壳上的轴管，其中，在两个在分型部处被分开的铸型半部中制造铸件，并且轴传动机构罩壳具有被凸缘包围的孔，该孔可被盖封闭，其中，径向环绕地均匀分布地在凸缘处相对于凸缘的平面成直角地构造盲孔螺纹孔，其超过凸缘的厚度伸入轴传动机构罩壳的壁的区域中。
背景技术
在这种类型的车轴中，已知的是，将盲孔螺纹孔布置在这样的分度圆上，使得当轴传动机构罩壳不具有作为抬高部从内壁伸入轴传动机构罩壳的内部中并且容纳并封闭盲孔螺纹孔的铸造耳孔时，盲孔螺纹孔伸入轴传动机构罩壳的内部中。但是，铸造耳孔减小了可供传动机构使用的空间，从而轴传动机构罩壳必须构造得更大，由此也具有更大的重量和更大的油体积。此外，铸造耳孔导致在车辆的行驶运行期间由于在传动机构罩壳中的涡流不利地影响油流动，由此不利地影响传动机构的润滑。在两个铸型半部中制造铸件，铸型半部的分型部在连续的中间平面中不仅延伸穿过轴管而且延伸穿过轴传动机构罩壳。
发明内容
因此，本发明的目标是，实现开头所述类型的车轴，其轴传动机构罩壳具有更小的结构空间和更小的重量并且改善了在传动机构罩壳的内部中的油流动。
根据本发明，该目标通过以下方式实现，即，在凸缘的面对轴传动机构罩壳的一侧上，轴传动机构罩壳径向向外地具有壁加厚部，壁加厚部沿着凸缘环形地径向环绕并且构造成连续环形的或者构造成局部地在盲孔螺纹孔的区域中形成铸造耳孔，其中，分型部在中间的平面中纵向地沿着轴管延伸并且在轴传动机构罩壳的区域中朝向凸缘被引导并且在凸缘处沿着壁加厚部的径向外轮廓被引导。
通过该构造方案，轴传动机构罩壳的内腔的大小可构造得很小，使得传动机构的组件可伸到传动机构罩壳的内壁附近。通过由此减小的轴传动机构罩壳的内腔，其整个结构尺寸进而其重量也减小。通过根据本发明构造分离缝隙，尽管有向外突出的壁加厚部，可无问题地使铸件脱模。由于现在耳孔不再径向伸入轴传动机构罩壳的内腔中，显著改善了在轴传动机构罩壳中的油流动。
如果在此轴传动机构罩壳的内腔的壁由向内突出的壁区域自由连续地拱起地形成，则在轴传动机构罩壳中实现尤其良好的油流动。
附图说明
在附图中示出并且以下详细描述本发明的实施例。其中：
图1示出了车轴的侧视图，
图2示出了根据图1的侧轴的立体侧视图。
具体实施方式
所示出的车轴具有轴传动机构罩壳1，两个轴管2彼此相反地从轴传动机构罩壳1离开。轴传动机构罩壳1和轴管2是一件式的铸件。
轴传动机构罩壳1具有钟形的形状，在其下侧处存在被凸缘4包围的孔3。在凸缘4中，径向环绕地均匀分布地并且相对于凸缘4的平面成直角地构造盲孔螺纹孔5，盲孔螺纹孔5利用其内端部区域伸到铸造耳孔6中，铸造耳孔6在凸缘4的面对轴传动机构罩壳1的一侧上构造为轴传动机构罩壳1的壁的壁加厚部。由此，盲孔螺纹孔5的内端部不是伸到外部而是被封闭。
在两个铸型半部中制造轴传动机构罩壳1和轴孔2的铸件，两个铸型半部的分型部在轴管2处沿着轴管2的中间平面7延伸并且在轴传动机构罩壳1的区域中作为过渡分型部8跃变至凸缘4并且在该处作为驱动机构罩壳分型部9沿着铸造耳孔6的径向外轮廓在凸缘4的驱动机构罩壳侧的一侧上伸延。
该分型部可视为在脱模的车轴处的分开毛边。
如可在图2中看到的那样，轴传动机构罩壳1的内腔11的壁10由内部突出的壁区域自由连续地形成。
