Description

双质量飞轮
技术领域
本发明涉及一种双质量飞轮,具有初级侧和次级侧,所述初级侧和次级侧能够围绕共同的旋转轴线抵抗弧形弹簧的复位力矩相对于彼此转动,其中所述初级侧包括初级质量板和初级质量盖。
背景技术
双质量飞轮从现有技术中、例如从DE 41 17 582 A1中已知。这种双质量飞轮用作为用于机动车的动力传动系中的扭振的减振器,其中双质量飞轮通常设置在驱动机动车的内燃机的曲轴和安装在换挡变速器上游的车辆离合器之间。通过抵抗弹簧力和必要时也抵抗干摩擦相对于彼此可转动的初级质量和次级质量,消除扭振,所述扭振通过通常构成为活塞马达的内燃机的不均匀的驱动力矩引起。
通常在初级侧的外部区域中需要接合几何结构作为操作接合部,用于在生产过程中操作构件,或用于在所谓的冷测试中滑转整个内燃机。在多种情况下,为此使用现有的硬化的或未硬化的且环绕地具有齿部的起动齿圈。如果不存在起动齿圈,那么使用单独的构件,所述构件的唯一的目的在于,提供冷测试所必需的接合几何形状。
发明内容
因此,本发明的目的是,提出在双质量飞轮中的操作接合部的简单的且成本适宜的实现方案。
所述目的通过根据本发明的双质量飞轮来实现。本发明的优选的实施方式、设计方案或改进方案在下文中给出。
在上文中提到的问题尤其通过一种双质量飞轮来实现,所述双质量飞轮具有初级侧和次级侧,所述初级侧和次级侧围绕共同的旋转轴线抵抗弓形弹簧的复位力矩可相对于彼此转动,其中初级侧包括初级质量板和初级质量盖,其中初级质量板和/或初级质量盖具有用于临时外部驱动的操作接合部。
初级质量盖在本发明的一个实施方式中具有两层的板区域,在所述板区域中引入操作接合部。初级质量板对此优选地包括内条和外条,其中操作接合部引入到外条中。通过翻转薄板的外部区域,能够简单地制成外条和内条,所述薄板是初级质量板的坯件。
接合部以脱模的方式(werkzeugfallend)已经在初级质量板的薄板中冲制并且随后在外部区域成型时一起翻转。操作接合部在本发明的一个实施方式中在外条中具有齿和齿隙,所述齿隙朝向背离初级质量板的侧的方向敞开。齿和齿隙由此能够冲制到初级质量法兰的薄板的外边缘中。
内条和外条优选地至少部分地沿轴向方向遮盖初级质量板。这在径向结构空间仅不明显更大的情况下节省轴向结构空间。
初级质量板在本发明的一个替选的实施方式中具有两层的板区域,在所述板区域中引入操作接合部。初级质量板在此优选地包括内条和外条,其中操作接合部引入到外条中。通过翻转初级质量盖的薄板的外部区域,能够简单地制成外条和内条,所述薄板是初级质量盖的坯件。
操作接合部在本发明的一个实施方式中在外条中具有齿和齿隙,所述齿隙朝向背离初级质量盖的侧的方向敞开。齿和齿隙由此能够冲制到初级质量法兰的薄板的外边缘中。
外条在本发明的一个实施方式中至少部分地沿轴向方向通过初级质量盖的外盖遮盖。由此,强度提高并且引起初级质量盖和初级质量板在焊接时的预定心。
外条在本发明的一个实施方式中具有用于容纳外盖的冲压部。由此,径向结构空间能够减小。
附图说明
本发明的实施例在下文中根据所附的附图详细阐述。在此示出:
图1示出根据本发明的双质量飞轮的第一实施例的剖面图,
图2示出图1的实施例的接合几何结构的俯视图,
图3示出根据本发明的双质量飞轮的第二实施例的剖面图,
图4示出图3的实施例的接合几何结构的俯视图。
具体实施方式
图1示出根据本发明的第一双质量飞轮的径向剖面。双质量飞轮1包括初级质量或初级侧2以及次级质量或次级侧3,其可抵抗弧形弹簧4的力相对于彼此围绕旋转轴线R转动。在下文中,只要没有另作说明,将轴向方向理解成平行于旋转轴线R的方向,将径向方向理解成垂直于旋转轴线R的方向,并且将环周方向理解成围绕旋转轴线R的转动。双质量飞轮1在机动车的未示出的动力传动系中设置在内燃机的曲轴和车辆离合器或辅助驱动装置(Nebenantrieb)之间。
初级质量2包括发动机侧的初级质量板6和离合器侧的初级质量盖5。初级质量板6和初级质量盖5包围弧形弹簧容纳部7,在所述弧形弹簧容纳部中设置有一个弧形弹簧4,必要时也设置有多个弧形弹簧4。弧形弹簧借助弹簧端部支撑在初级质量2上,例如支撑在此处未示出的凸起处,或者支撑在压到板中的止挡处,所述止挡伸入到由初级质量板6和初级质量盖5包围的弧形弹簧容纳部7中。借助相应另一弹簧端部,弧形弹簧4支撑在次级凸缘8的凸缘翼处。凸缘翼径向向外延伸并且围住弧形弹簧4的弹簧端部。
次级法兰8借助于主铆接装置的铆钉9与输出毂10固定地铆接。铆钉9在主铆接圈上分布地设置。输出毂10具有用于在此仅示意地示出的曲轴螺丝12的孔11,用于将双质量飞轮1与未示出的曲轴拧紧。输出毂10在径向内部具有L形的靴状部13,所述靴状部具有插接齿部14,用于与在下游设置的转矩传递机构连接。靴状部13借助于横截面为L形的支承环15在初级质量板6的支承拱顶16处定心从而次级侧3相对于初级侧2定心。
借助主铆接装置,碟形弹簧密封膜片17固定在次级侧3上。碟形弹簧密封膜片17借助其外部区域与初级质量盖5接触,从而相对于周围环境密封弧形弹簧容纳部7。在碟形弹簧密封膜片17和初级质量盖5之间的接触区域设有滑动环18,所述滑动环能够如在示出的实施例中那样在初级质量盖5的环绕的凸肩处径向定心,并且轴向地固定在初级质量盖5和碟形弹簧密封膜片17之间,或者例如粘接或卡扣。输出毂10中的安装孔19能够实现拧紧曲轴螺丝12。
在弧形弹簧4的外环周处,滑动套筒20设置在初级质量板6处,所述滑动套筒减小弧形弹簧4相对于初级质量板6的摩擦和磨损。
初级质量板6具有基本上径向伸展的区域,所述区域在径向外部是罐形的从而具有轴向伸展的空心柱形的区域21,所述区域在外部包括弧形弹簧容纳部7并且承载滑动套筒20。空心柱形的区域21的自由端部借助于焊接缝22与初级质量盖5焊接。焊接缝22能够环绕地或中断地构成并且优选地是通过激光焊接制造的V形缝,所述V形缝穿过初级质量盖5的板到达初级质量板6的材料中。
在初级质量板6的轴向伸展的区域21的径向外部,初级质量盖5具有空心柱形的卷边23,所述卷边本身包括内条24和外条25。空心柱形的卷边23包围初级质量板6的轴向伸展的区域21。外条25具有齿26和齿隙27作为操作接合部28。图2示出外条24的展开。
在图3的实施例中,初级质量板6的空心柱形的区域21同时是内条并且具有带有外条25和操作接合部28的卷边23。初级质量板6因此包括内条24和外条25,其中操作接合部28作为接合几何结构引入到外条25中。
初级质量板5借助外盖29包围外条25。外条25具有压印部或切削加工的车削部(Eindrehung)30,用于部分地容纳外盖29。
图4示出操作接合部28的展开。
操作接合部28以脱模的方式在相应的构件、即初级质量板6或初级质量盖5的薄板中冲制并且随后在外部区域成型时一起翻转。
