Description

扭振减振器及用于制造该扭振减振器的方法
技术领域
本发明涉及一种尤其用于机动车的驱动系的扭振减振器，其具有一个输入部件和一个输出部件，所述输入部件能围绕一旋转轴线转动，所述输出部件能抵抗在输入侧被加载的弹簧装置的作用而相对扭转，所述输出部件具有一个在输出侧借助径向扩展的臂加载所述弹簧装置的法兰部件和一个与该法兰部件连接的具有内齿部的毂部件。
背景技术
扭振减振器尤其在具有内燃机的机动车驱动系中用于阻尼该内燃机的扭转振动，其方式是一个与内燃机曲轴固定连接的输入部件抵抗一个弹簧装置的作用相对于一个输出部件相对地扭转，所述输出部件将输入转矩传递到后级动力单元，例如变速器、双离合器或类似物。在此情况下，当转矩峰值期间所述弹簧装置被压缩并且将此时存储的能量在一个转矩谷值时再输出到驱动系中，以使得总体上在该扭振减振器后面比在其前面出现更加均匀的转矩变化过程。在此情况下，为了改善扭振减振器的振动隔离被证明特别有效的是：在构成一个分体式飞轮的情况下给输入部件配属一个初级飞轮质量并且给输出部件配属一个次级飞轮质量。在此情况下，一些构件如动力单元及类似物，例如的、双离合器的、转矩变换器等的构件可用作次级飞轮质量。
例如由DE 10 2012 202 255 A1已知一种扭振减振器，其输出部件包括一个具有内齿部的毂部件，该内齿部与后级动力单元形成转动锁合。此外，设置有与一个法兰部件的转动锁合连接部，该法兰部件包括向径向外部扩展的臂，所述臂承担弹簧装置的在输出侧的加载。
发明内容
本发明的目的在于提供一宗扭振减振器的有利改进方案以及一种用于制造扭振减振器的改进方法。尤其要使组装变得容易并且使制造成本降低。
该目的将通过本发明的设备以及本发明的方法来实现。在说明和附图中给出了该设备的有利实施方式。
该建议的扭振减振器尤其适用于机动车的驱动系，用于该驱动系的内燃机的振动减振。为此，该扭振减振器包括：能围绕旋转轴线转动的输入部件，所述输入部件例如由一个被内燃机曲轴驱动的第一盘形部件和一个与该第一盘形部件在径向外部固定地且紧密连接的第二盘形部件形成；以及一个抵抗弹簧装置的作用能相对扭转的输出部件，所述弹簧装置被接收在一个由这两个盘形部件形成的环形室中并且被所述盘形部件在输入侧加载、例如借助压印成型部加载，该输出部件具有一个在输出侧加载所述弹簧装置的法兰部件和一个与该法兰部件连接的毂部件，其中，法兰部件与毂部件一体式地构造为盘形部件。由此，取消了毂部件与法兰部件之间的铆接。此外，节省了组装成本并且减少了法兰部件的冲压移除(Stanzausbruch)。
该盘形部件在径向外部具有径向扩展臂，所述径向扩展臂配合到环形室中，该径向扩展臂在驱动系中的转矩流的牵引方向和/或滑移方向上对所述弹簧装置的储能器——例如弓形弹簧、直的螺旋压力弹簧或类似物——在端侧上加载。该盘形部件在径向内部具有内齿部，该内齿部例如可设置在盘形部件的一个轴向弯转突头的内周缘上。该内齿部相对于一个轴(例如为变速器输入轴)、相对于一个轴颈(例如双离合器的输入部件)、相对于一个转矩变换器或类似动力单元、或相对于类似物形成转动锁合。
所述盘形部件优选地局部不同地被硬化。例如，为了设定内齿部的硬度，整个盘形部件被热硬化，例如被退火。
所述盘形部件的机械上强负荷的臂可附加地通过感应被硬化。
所述盘形部件可在硬化前由板材例如借助冲压和成型方法被制成。该盘形部件除内齿部的拉削
Figure GDA0002668812930000021
之外可不用刀具地(werkzeugfallend)制造。
该建议的用于制造所建议的扭振减振器的方法包括：由板材制造具有一个设置在径向内部的轴向突头的盘形部件的冲压和板材成型工艺以及硬化工艺，其中，使所述盘形部件在第一硬化步骤中硬化、例如退火，并且，在第二硬化步骤中使所述盘形部件的臂通过感应来硬化。此外，该方法还包括拉削工艺，在该拉削工艺中拉削出所述内齿部。所述内齿部的拉削优选地在第一硬化步骤之后并且在第二硬化步骤之前实施。以下将借助在唯一附图中示出的实施例详细地解释本发明。该图示出根据本发明的扭振减振器的部分截面。
附图说明
唯一的附图示出以能围绕旋转轴线d扭转的方式设置的扭振减振器1的上部。
具体实施方式
唯一的附图示出以能围绕旋转轴线d扭转的方式设置的扭振减振器1的上部。输入部件2和输出部件3被构造为能抵抗弹簧装置4的作用受限地相对扭转。输出部件3由具有径向扩展臂6的法兰部件5和具有内齿部8的毂部件7构成。法兰部件5和毂部件7一体式地构成盘状部件9。
输入部件2在构成一个初级飞轮质量的情况下包括两个在径向外部相互紧密连接、例如焊接的盘状部件11，12和飞轮齿圈13。盘状部件11借助螺钉14被接收在一个未示出的曲轴上并且通过盘状部件9的一个穿通开口15与该曲轴旋紧。
盘状部件11，12形成环形室16，在该环形室中接收弹簧装置4的弓形弹簧17。用于在周向方向上在弓形弹簧端侧加载弓形弹簧17的输入侧加载装置借助盘状部件11，12的不可见的压印成型部来实现。弓形弹簧17的输出侧加载借助由径向内部配合到环形室16中的臂6来实现。环形室16向径向内部在盘形部件9与盘形部件11，12之间借助由碟簧19在轴向上压紧的密封件18在构成摩擦装置的情况下被密封。
通过盘形部件9一体式构造取消了在法兰部件5与毂部件7之间的铆接。由此可节省由铆钉所需的轴向安装空间。此外，使单个盘形部件9的库存管理和该扭振减振器1的组装简化。另外，可节省材料，因为消除了法兰部件5的冲压移除的冲压废料。
在此情况下，盘形部件9适配于在不同的几何区域或功能区域中的不同的硬度要求。一方面设定用于形成内齿部8的预给定的硬度，另一方面设定与此不同的臂6的硬度。借助冲压和成型方法制造盘形部件9要求板材原材料的硬度小。因此，在第一步骤中借助冲压和成型方法制造具有轴向突头10的盘形部件9的坯件。接着，该坯件被热硬化、例如退火。再接着，在轴向突头10上借助拉削工艺拉削出内齿部。最后，臂6在盘形部件9的径向外部局部地优选用感应方法设置具有较大硬度。
