相关申请的交叉引用
本申请要求于2013年7月25日提交的美国临时专利申请No.61/858,172的权益,该申请的内容通过参引并入本文,就如同已在本文中充分地陈述。
技术领域
本发明涉及隔离器,并且具体地涉及在发动机曲轴与环状驱动构件比如带之间使用的隔离器。
背景技术
隔离器通常用于使曲轴带轮及其相关联的带(例如,辅助驱动带)与来自曲轴的扭转振动隔离,该扭转振动是内燃发动机——特别是具有特定缸数的发动机如四缸或三缸发动机——以及柴油发动机中的质量块(例如,活塞)往复运动的结果。一些隔离器包括两对弹簧,其中,每对弹簧中均存在具有中央孔口的一个外弹簧以及定位在外弹簧的中央孔口中的一个内弹簧。然而,由于内弹簧在中央孔口中的滑动运动——原因在于在很多情况下内弹簧在纵长方向上比外弹簧更短,因此这种隔离器遭受噪音问题。
发明内容
一方面,提供了一种用于隔离器或任何其他合适的扭矩传递装置的弹簧组件,该弹簧组件包括第一螺旋压缩弹簧和第二螺旋压缩弹簧、保持器以及弹簧壳体。第一螺旋压缩弹簧具有中央孔口并且具有第一端部和第二端部。第二螺旋压缩弹簧具有中央孔口并且具有第一端部和第二端部,其中,第二弹簧与第一弹簧同轴并且嵌套在第一弹簧内。保持器具有基部和柱状部,该柱状部从基部延伸并进入位于第二螺旋弹簧的第一端部处的中央孔口中。弹簧壳体具有内部空间,第一弹簧和第二弹簧定位在该内部空间中,并且弹簧壳体还包括基部接合孔口,该基部接合孔口对保持器的基部进行保持。弹簧壳体包括驱动壁,该驱动壁与第一弹簧的第一端部和第二弹簧的第一端部接合。
另一方面,提供了一种隔离器,该隔离器包括上述弹簧组件。
通过参照附图的以下描述,其他特征和优势将变得明显。

图8为可以与隔离器一起使用的替代性保持器的立体图;以及
图9为具有图8中示出的保持器的两个弹簧的立体图。
具体实施方式
参照图1,其示出了根据本发明的实施方式的用于在发动机14上的曲轴与环状驱动构件16如辅助驱动带之间传递动力的隔离器10。隔离器10使环状驱动构件16与曲轴中的扭矩的振动或其他突然改变隔离,并且隔离器10使曲轴与环状驱动构件16中的扭矩的振动或其他突然改变隔离。
如图2和图3中所示,隔离器10包括带轮18、驱动件20、第一隔离弹簧和第二隔离弹簧的组件21,该组件21包括至少一对第一、第二弹簧22(第一弹簧和第二弹簧分别以22a和22b示出)、保持器39以及可选的弹簧外壳24。
驱动件20能够以任何合适的方式固定地安装至曲轴以绕轴线A旋转。例如,可以设置轴转接器26,该轴转接器26经由穿过转接器26中的孔口并进到曲轴的端部中的螺纹孔口32中的多个带螺纹的紧固件(在图1中以28示出)比如四个内键槽圆柱头螺钉(splinesocket head cap screws)安装至曲轴。
驱动件20可以由任何合适的材料比如合适的金属如钢制成。
轴转接器26可以包括用于支承衬套36的支承表面34,衬套36又支承带轮18上的衬套接合表面38,从而允许带轮18与曲轴之间、轴转接器26与驱动件20之间的相对旋转。衬套36还可以包括作为止推衬套部的径向唇缘,该止推衬套部在轴向方向上通过带轮18接合并支承带轮18。衬套36可以由任何合适的材料如尼龙制成。
带轮18被支承以相对于曲轴旋转并且能够与带16接合。应当注意的是,为方便起见而使用术语“带”,但可以代之以任何合适的环状驱动构件。类似地,为方便起见而使用术语“带轮”,但可以代之以能够与环状驱动构件接合的任何合适的旋转构件。
带轮18在示出的实施方式中具有构造成接合多V形槽带(poly-V groove belt)的带接合表面40。带轮18可以由两个元件构成,所述两个元件包括主要部分18a以及通过任何合适的方式(例如,借助于压配合)连接至主要部分18a的盖构件18b。带轮18可以由任何合适的材料比如合适的金属如钢制成。
弹簧组件22弹性地变形以使环状驱动构件16与曲轴中的扭矩的振动或其他突然改变隔离并且使曲轴与环状驱动构件16中的扭矩的振动或其他突然改变隔离。示例中的弹簧组件22各自包括第一弓形的螺旋线圈压缩弹簧22a和第二弓形的螺旋线圈压缩弹簧22b以及保持器39,其中,第一弓形的螺旋线圈压缩弹簧22a和第二弓形的螺旋线圈压缩弹簧22b中的一者嵌套在另一者内。
尽管图2中示出了两个弹簧组件22,但是将理解的是,隔离器替代性地可以具有单个弹簧组件22或者三个或更多个弹簧组件22。
为简化起见,图3仅示出了弹簧壳体24中的一个弹簧组件22。参照图3、图4和图5,弹簧22a和弹簧22b中的每一者均具有第一端部,弹簧22a的第一端部以42a示出,并且弹簧22b的第一端部以42b示出。弹簧22a和弹簧22b中的每一者均具有第二端部,弹簧22a的第二端部以44a示出,并且弹簧22b的第二端部以44b示出。第一弹簧22a可以被称为外弹簧22a并且具有中央孔口46,第二弹簧或内弹簧22b在该中央孔口46中延伸。第二弹簧22b也具有中央孔口47,如图4中所示。
参照图4和图5,保持器39包括基部102和突出部104。柱状部104从基部102延伸并且紧密地配装到位于第二弹簧22b的第一端部42b处的中央孔口47中。弹簧壳体24具有内部空间106,第一弹簧22a和第二弹簧22b定位在该内部空间106中,并且弹簧壳体24还包括基部接合结构108,该基部接合结构108对保持器39的基部102进行保持。弹簧壳体24包括驱动壁110(其由第一驱动壁部110a和第二驱动壁部110b构成),该驱动壁110直接接合第一弹簧22a的第一端部42a和第二弹簧22b的第一端部42b,使得弹簧22a与弹簧壳体24之间和弹簧22b与弹簧壳体24之间的力传递直接地而非通过保持器39进行。
如可以在图5中观察到的,基部102延伸横跨过第一弹簧22a的第一端部42a和第二弹簧22b的第一端部42b两者。
在弹簧22a和弹簧22b定位在弹簧壳体24中的情况下,第一弹簧22a将处于略微预加载或压缩的状态。这将基部102固定在基部接合结构108中并且确保第一弹簧22a与保持器39之间没有运动。第二弹簧22b借助于紧密安装至保持器39的柱状部104而相对于第一弹簧22a保持固定就位。
弹簧22a和弹簧22b可以由任何合适的材料比如合适的金属如钢制成。
保持器39可以由任何合适的材料比如聚合物材料如尼龙或者允许保持器39紧密地***到第二弹簧22b的中央孔口47中的一些其他的柔性材料制成。
尽管弹簧壳体24被示出为是与带轮18分开的单独结构,但是替代性地,弹簧壳体24可以与带轮18成一体。带轮18可以以任何合适的方式接合弹簧壳体24,比如通过带轮上的凸耳,该凸耳接合弹簧壳24中的凸耳接纳孔口,以及/或者通过压配合连接。
驱动件20具有中央本体48、第一臂部50a和第二臂部50b。第一臂部50a和第二臂部50b中的每一者均具有第一侧部52和第二侧部56。第一侧部52能够与其中一个第一弹簧22的弹簧端部44a接合以在第一侧部52与弹簧端部44a之间传递扭矩。此外,如果驱动件20与带轮18之间的扭矩传递高到足以引起弹簧22a的大量压缩,则臂部50a和臂部50b的第一侧部52就能够与第二弹簧22b的弹簧端部44b接合,此时,弹簧22a和弹簧22b两者均用于在驱动件20与带轮18之间传递扭矩。通常,扭矩传递会从驱动件20向弹簧22并且从弹簧22通过弹簧壳体24向带轮18进行,而基本上不通过保持器39传递任何力。
保持器39用于防止内弹簧22b在中央孔口46中向周围滑动。
参照图3,弹簧壳体24可以由两个弹簧壳体部24a和弹簧壳体部24b构成,所述两个弹簧壳体部24a和弹簧壳体部24b可以以任何合适的方式装配在一起,例如通过使用壳部24a和壳部24b中的任一者或两者上的一个或更多个夹扣构件装配在一起,其中,所述一个或更多个夹扣构件接合构造成以锁定的方式接纳所述一个或更多个夹扣构件的夹扣接纳肩部。所述两个壳体部24a和壳体部24b可以共同限定基部接合结构108并且可以提供与保持器39的基部102的压配合。
在示出的实施方式中,隔离器10还包括密封构件88、密封偏置构件90和防尘罩92。这些构件配合以防止润滑剂(例如,润滑脂)从带轮的内部空间泄露出来并且阻止灰尘和碎屑进入隔离器10的内部空间中。密封构件88还作为通过密封偏置构件90而被推动至与带轮18(具体地为盖构件18b)接合的另一止推衬套,以推动带轮18和衬套36越至抵靠轴转接器26上的在支承表面34的一个端部处的肩部的基准点。防尘罩92可以替代地为一些其他部件例如扭转振动阻尼器,该扭转振动阻尼器经由驱动件20a和轴转接器26间接地连接至曲轴,以在曲轴的扭转振动期间特别是在较高的RPM(每分钟转数)下减小曲轴的角度往复运动的幅度。
轴转接器26上的突出部94(图1a和图2)可以穿过防尘罩92、偏置构件90和驱动件20中的孔口,以确保这些部件与轴线A对准。突出部94可以随后进行固接,使得所有这些部件均保持安装至轴转接器26,从而形成子组件。
参照图8,其示出了保持器139,该保持器139与保持器39类似并且具有基部102,但该保持器139的柱状部111具有沿周向延伸的凹部112。凹部112接合内弹簧22b的线圈以将内弹簧22b更好地保持在凹部112上。
尽管弹簧22a和弹簧22b的弧长示出为不同(使得第二弹簧22b的弧长比第一弹簧22a的弧长更短),但是替代性地,两个弹簧22a和弹簧22b可以具有相同的弧长。
在示出的实施方式中,已经对待安装在发动机14的曲轴上的隔离器10进行了描述。应当注意的是,隔离器10替代性地可以安装在由带16驱动的附件的轴上,例如转向泵的轴上。在这种实施方式中,扭矩传递通常将从带轮18通过隔离弹簧22向驱动件20和轴转接器26进行。在这种实施方式中,驱动件20将驱动附件的轴而非驱动带轮18。更广泛地,隔离器10可以在任何发动机上用于在任何合适的输入构件(比如带,或曲轴)与任何合适的输出构件(比如辅助输入轴,或带)之间进行隔离。另外,驱动件20仅为第一旋转驱动构件的一个示例,并且带轮仅为第二旋转驱动构件的一个示例。例如,带轮18可以替代地为齿轮,该齿轮驱动传动***并且该齿轮由发动机曲轴经由驱动件20并通过隔离弹簧22驱动。
尽管发动机14可以是车用发动机,但是将理解的是,发动机14可以是用于工业应用等的固定式发动机。
尽管以上描述构成了本发明的多个实施方式,但是将理解的是,在不背离所附权利要求的真实意义的情况下,本发明能够做出进一步修改和改变。
