Abstract
一种差速器锁,其具有离合器构件(1),所述离合器构件具有用于保持一弹簧(7)与对应设置的另外的离合器构件中的销(3、4)共线的弹簧保持孔(2)。穿过离合器构件的侧面(11,12)的弹簧通道由完全穿过离合器构件侧壁且从离合器构件(1)内面延伸的槽口(10)来提供。
Description
技术领域
本发明尤其涉及具有用于将车辆驱动轴正常连接到一对轴向对齐的从动半轴的环形摩擦架离合器构件类型的差速器锁。
发明背景
本发明所指向的技术领域较好地陈述在其他各种技术说明书中,例如1998年公开的美国专利说明书5836220,以及以Zentmyer名义的美国专利5413015和以Dissett名义的美国专利5715733。在这些例子的每一个中,公开了由多个弹簧组件偏置分离的一对离合器构件,其中每一个弹簧组件包括相对于一个或更多个螺旋弹簧共线布置的锁销。
本发明所指向的问题可通过参考美国专利5715733中的附图得到最好的解释,其中图14、15和16显示了弹簧穿过弹簧通道开口(spring accessopening)32***以便与锁销共线作用的方式。
该问题涉及同样的专利5715733中图9、10、11和12中所显示的离合器构件的制造问题。
这种产品的制造成本取决于任何相关制造技术的难度。
已经发现,通过改变弹簧夹持孔(spring holding aperture)的形状,能极大地节约制造时间和制造成本。
发明内容
所建议的是,不是具有如所显示的穿到过大孔洞(oversized bore)的窗口形式的弹簧通道开口,而是弹簧通道开口被加长以便其与内面相通。
然而,这意味着弹簧不能保持在适当位置,因此,提供强制使弹簧位于内端的装置,并提供一种相对于弹簧另一端的止动销与弹簧配合的联锁装置(interlocking)。
这种改变的优点出现的原因是这种改变允许离合器构件的制造被限制到仅使用三个轴而不是如今的情形,四个轴。
如将要看到的,如果将端铣刀引入离合器构件的端面以切割过大的弹簧保持孔洞(oversized spring retaining bore),那么就很容易使铣刀还沿直径前进以便切穿到达外壁且穿过该外壁,并因此留下槽口(slot)。
因此,这样避免了不得不继续使用的机械加工,在机械加工中,刀具不得不被定向以便围绕直径方向旋转来实现切割细长形弹簧通道开口。
因为避免了这种情况,所以零件本身的制造也变得更简单了。
然而,进一步,能涉及较少复杂的机械方法且在一些例子中,因此,能包括比如果要求第四轴切割时更经济实用的机床。
本发明的又一进一步优点在于其便于批量生产,其中可用单一机床而不需要重新定位零件来制造多个零件。
本发明的一个形式可以被说成是在于一种差速器锁(differentiallocker),其具有离合器构件(clutch member),该离合器构件具有用于保持一弹簧与对应设置的另外的离合器构件中的销共线对齐的弹簧保持孔(spring retaining aperture),特征在于:穿过离合器构件侧面的弹簧通道(spring access)由完全穿过离合器构件侧壁且从一内面延伸的槽口来提供。
优选地,当弹簧保持在这种离合器构件中时,弹簧与共线对齐的销的一端相互啮合。
优选地,弹簧的另一端通过定位在弹簧保持孔内的孔洞中而被保持。
优选地,该离合器构件对具有多个这样对齐的销和弹簧,且在一侧有对称设置的孔洞,在另一侧有弹簧保持孔。
优选地,所讨论的弹簧是螺旋弹簧,且该弹簧通过所述销而相对于共线对齐的所述销的端部被保持,所述销具有较小直径部分以便装配在该螺旋弹簧的中心孔洞中。
优选地,弹簧保持孔包括比离合器构件侧面的开口更深的孔洞且具有至少和弹簧底部直径一样大的直径以便弹簧能因此而引出,且当使用时保持在其中。
所描述的布置的一个重要优点也在于,当在由差速器提供的足够***这种类型离合器构件的有限空间中组装时,其更易于以此方式***弹簧。
附图说明
为了较好地理解本发明,现将借助图形来描述本发明,其中:
图1是带有相关联的弹簧和共线对齐的销的离合器构件的透视图;
图2是截面图,显示了两个离合器构件的组件,其中共线保持的销部分地啮合到弹簧保持孔中;以及
图3是进一步的透视图并切掉了一部分,展示了销与弹簧保持过大孔(spring retaining oversized aperture)对齐的方式以及销是如何放置在底部孔洞(bottom bore)中并与共线销底端联锁的。
具体实施方式
详细参考附图,如所看到的,将描述离合器组件的一部分,即被显示为1的离合器构件包括多个孔2,这些孔2设置成以相对的紧密配合容纳可滑动的止动、圆柱状销3和4。
这些弹簧保持孔的形状相对复杂,因此希望他们能够用被编制程序来沿着特定路径的单一切割刀具切割。
此路径包括切割带有一部分比另一部分深的细长形深孔洞(deep bore)以便提供弹簧座。
刀具的进一步路径是从相对于过大孔洞(oversized bore)的细长部位的中心位置前进穿过壁以便从而切割带有平行侧面11、12的槽口10且具有至少足以满足弹簧7穿过那里的宽度。
弹簧7意欲与销3的端部8联锁,销3在端部具有比销的主体直径小的部分,以便其能安装在螺旋弹簧的孔内。
其后,当然能够由于以下事实而使该离合器构件成为可能,在销处于适当的位置后,每个弹簧能以相对自由度***,以使销的端部部分能被定位到各自的螺旋弹簧的孔洞和该弹簧的底部中以便延伸和坐落且因此保持在深孔洞部分中。
如前面所描述的,此设置的优点是双重的,第一在于现在将能更便宜和更方便的制造具有该类型孔的离合器构件,以及第二,其便于随后安装根据此设计的差速器锁。
本发明的目的已经全部展示在说明书中且并不限于此。
