Abstract

扭梁（10）由管制造而成，其在“V”或“U”形的中心部段具有较短的截面周长且在梁的两端（14，16）具有较长的截面周长。本发明因此提出使用具有预定长度的管状件,管状件在中心部段变形成“V”或“U”形形状并在两个端部处扩大，这种结构使用封闭模内压成形工艺如液压成形、吹塑成型等获得。管状件的两端也可具有大致椭圆形或圆形的截面。在封闭模内压成形工艺过程中，也可以对本发明的管状件进行热处理以获得较高的材料强度。通过这种方式，本发明的扭梁被优化成沿其整个长度使用最小的合理截面，因此比当前的由管材制成的扭梁质量要低得多，并且这种扭梁可以使用较少的材料制造并因此具有相当低的成本。

Description

截面优化的扭梁
发明内容
根据本文公开的实施例提供了一种扭梁。本发明中的扭梁由管制造而成，其在“V”或“U”形的中心部段具有较短的截面周长且在该扭梁两端具有较长的截面周长。本发明因此提出使用具有预定长度的管,该管使用封闭模内压成形工艺如液压成形、吹制成型等，在中心部段变形且在两端部扩大。本发明的扭梁也可在吹制成型过程中进行热处理以提高其强度并因此提高其耐疲劳性能。因此，本发明的扭梁被优化成沿其整个长度使用最小的合理截面，因此比当前由管材制成的扭梁质量要低得多，及可使用较少的材料制造并因此具有相当低的成本。
附图说明
参照附图，现在通过示例来描述本发明：
图1示出了执行成形工艺前扭梁的一个实施例（呈管状件形式）的透视图。
图2示出了在执行成形工艺后扭梁的一个实施例的透视图。
图3示出了图2中的扭梁部分切除的视图。
图4示出了图2中扭梁的一个实施例沿线4-4的横断面视图。
图5示出了图1中管状件（成形之前）的一个实施例沿线5-5的横断面视图
具体实施方式
本发明提供一种扭梁10，如图2中的非限制性例子所示，该扭梁由管状件18制成，并在“V”或“U”形中心部段12具有较短的截面周长和在梁两端具有较长的截面周长。
因此，本发明的第一步骤是提供预切割成预定长度的管状件18。本发明的第二个步骤是执行内压成形工艺，例如但不限于液压成形或吹制成型等，以将管状件18的中心部段12变形成“V”或“U”形，同时扩大第一端（或端部）14和第二端（或端部）16。在一个非限制性的例子中，管状件18的直径从约80毫米扩大到约90毫米。通过使用封闭模内压成形工艺，如在非限制性的例子中为液压成形或吹制成型等，来获得期望的形状。
应当理解，在成形工艺后，梁的两端也可具有大致椭圆形或矩形的截面。还应当理解,可使用通过引用纳入本文的美国专利US6,261,392中的吹制成型工艺。因此，本发明还包括对材料进行热处理的步骤，以获得较高的材料强度并因此获得较高的耐疲劳性能。
如图2所示，本发明的扭梁10由等截面管状件18制造而成，并在“V”或“U”形中心部段12具有较短的截面周长，而在扭梁的两端（第一端14和第二端16）处通过扩大管状件18的第一端14和第二端16而具有较长的截面周长。“V”或“U”形形状使用封闭模内压成形工艺或类似工艺获得。
在一个非限制性的例子中，本发明因此提出使用内径为约80毫米，并预切割成预定长度的管状件18。使用封闭模内压成形工艺，例如但不限于液压成形、吹制成型等，（如图1所示）的管状件18在其中心部段12变形成图2所示的“V”或“U”形。而且，同时在封闭模22、24中，管状件18在第一端（或端部）14和第二端（或端部）16处扩大至直径为约90毫米。
在另一非限制性的例子中，本发明因此提出使用内径为约80毫米并预切割成预定长度的管状件18。使用合适的热源，例如但不限于输送式加热炉、感应炉等将管状件18加热至奥氏体态后进行吹制成形工艺，管状件18在其中心部段变形成如图2的“V”或“U”形。而且，同时在封闭模22、24中，管状件18在第一端（或端部）14和第二端（或端部）16处扩大至直径为约90毫米。此外，当仍然还在封闭模22，24中时，在成形完成后，对管状件18进行淬火以提高其强度和耐疲劳性能。
因此，本发明的扭梁10被优化成沿其整个长度使用最小的合理截面，因此比当前的由管材制成的扭梁质量要低得多，并且这种扭梁可以使用较少的材料制造并因此具有相当低的成本。
本领域技术人员应当理解，虽然已经参考一个或多个优选实施例对本发明进行了描述，但本发明并不局限于这些公开的实施例，在不脱离本发明范围的情况下，可以这些公开的实施例进行多种替代或更改。
