Abstract

本发明公开了一种双质量飞轮，通过不将惯性体安装于变速器的输入轴上有可能防止安装性能由于变速器的长度增加而恶化并且通过使用2-缸和3-缸发动机、降速或停缸CDA而有效地降低变速器的输入轴的旋转振动，从而能够有效地抑制变速器的咔嗒声。

Description

双质量飞轮
相关申请的交叉引用
本申请要求2012年12月10日提交的韩国专利申请No.10-2012-0142614的优先权，该申请的全部内容结合于此，以用于通过该引用的所有目的。
技术领域
本发明涉及一种双质量飞轮，并且更具体地，涉及一种通过抑制变速器的输入轴的旋转振动来降低所述变速器的咔嗒声（rattling）的技术。
背景技术
如下述专利文献1和2中所公开，当变速器的咔嗒声是一个问题时，通过在即使不使用双质量飞轮（DMF）等的变速器的输入轴上安装惯性盘，有可能有效地避免特定频带中的共振。
然而，在变速器的输入轴上具有惯性盘的结构中，所述输入轴上需要有空间以安装所述惯性盘，并且需要该空间以扩大变速箱，因此难以安装所述惯性盘或增加所述变速器的长度，这使其难以在车辆上安装所述变速器。
进一步地，最近，由于应用发动机的降速（down-speeding）或者使用2-或3-缸发动机或者使用用于提高燃油效率的技术如停缸（CDA），因此在某些情况下，即使使用相关技术中的DMF也不足以有效地降低变速器的输入轴的旋转振动。
现有技术的典范是KR10-2007-0039819A和KR10-2009-0049295A号韩国专利申请。
公开于本发明背景部分的信息仅仅旨在增加对本发明的总体背景的理解，而不应当被视为承认或以任何形式暗示该信息构成已为本领域技术人员所公知的现有技术。
发明内容
本发明的各个方面提供了一种双质量飞轮，其通过不在变速器的输入轴上安装惯性体能够防止安装性能由于变速器的长度增加而恶化并且通过有效地抑制变速器的输入轴的旋转振动（使用2-缸和3-缸发动机、降速或CDA）能够有效地抑制变速器的咔嗒声。
本发明的各个方面提供了一种双质量飞轮，其包括：初级轮；次级轮，其相对于所述初级轮旋转；DMF弹簧，其随着所述初级轮和所述次级轮之间的相对旋转而发生弹性形变；传动盘，其与所述次级轮整体地连接并且使所述初级轮和所述传动盘之间的所述DMF弹簧发生弹性形变；和惯性盘，其相对于所述传动盘发生弹性旋转。
本发明的方法和装置具有其他的特征和优点，这些特征和优点在（并入本文中的）附图和随后的具体实施方式中将是显而易见的或者在其中得到详细陈述，这些附图和具体实施方式共同用于解释本发明的特定原理。
附图说明
图1是说明根据本发明的示例性双质量飞轮的结构的视图。
图2是说明图1中所示结构在另一个角度上的视图。
图3是说明本发明的示例性双质量飞轮的原理和操作的视图。
应当了解，附图并不必须是按比例绘制的，其示出了某种程度上经过简化了的本发明的基本原理的各个特征。在此所公开的本发明的特定的设计特征，包括例如特定的尺寸、定向、定位和外形，将部分地由特定目的的应用和使用环境所确定。
在这些附图中，在贯穿附图的多幅图形中，附图标记指代本发明的相同或等效的部分。
具体实施方式
现在将具体参考本发明的各个实施方案，在附图中和以下的描述中示出了这些实施方案的实例。虽然本发明与示例性实施方案相结合进行描述，但是应当了解，本说明书并非旨在将本发明限制为那些示例性实施方案。相反，本发明旨在不但覆盖这些示例性实施方案，而且覆盖可以被包括在由所附权利要求所限定的本发明的精神和范围之内的各种替换、修改、等效形式以及其它实施方案。
参考图1和图2，本发明的双质量飞轮的各种实施方案可以包括：初级轮1；次级轮3，其能够相对于初级轮1旋转；DMF弹簧5，其随着初级轮1和次级轮3之间的相对旋转而发生弹性形变；传动盘7，其与次级轮3整体地连接并且使初级轮和传动盘7之间的DMF弹簧5能够发生弹性形变；和惯性盘9，其相对于所述传动盘7能够发生弹性旋转。将会理解的是，所述传动盘可以与所述次级轮一体地形成。
换言之，通过向相关技术的双质量盘（dual mass plate）的配置中添加惯性盘9（其能够相对于传动盘7发生弹性旋转）来实施配置并且在所述双质量板中实施输入轴减振器（ISD）（其被安装在变速器的所述输入轴上）以便有可能解决在不增加变速器的输入轴长度的前提下限制空间以安装ISD的问题并且减少或防止所述变速器的咔嗒声。
惯性盘9通过传动盘7内的调谐弹簧11与传动盘7连接并且在旋转的同时压缩或延展发生相对旋转的调谐弹簧11。
通常，初级轮1被连接至发动机的曲轴并且次级轮3被连接至变速器的输入轴，以便通过调谐弹簧11与次级轮3连接的惯性盘9提供了与通过弹性元件（如相关技术的ISD）将惯性力施加至与次级轮3连接的变速器的输入轴上的相同的效果。
在各种实施方案中，惯性盘9以与传动盘7同轴布置的环状线圈形或圆环形形成，多个支撑突起13被配置在所述环形线圈形状外侧的周围，并且调谐弹簧11被配置在支撑突起13的两侧。
因此，在动力的传递中，由于惯性盘9和传动盘7相对旋转，所以支撑突起13在发生旋转的同时延展调谐弹簧11的一侧并压缩另一侧，从而将惯性力弹性地提供至变速器的输入轴。
此外，在传动盘7的一侧形成可将所述惯性盘插入的插入凹槽，并且惯性盘9被插入到传动盘7的所述插入凹槽中从而使得它被定位在传动盘7的外部边界的内侧，以便有可能实施相关技术的ISD的功能，其中不增加相关技术的DMF的体积。
根据本发明，通过不将惯性体安装于变速器的输入轴上有可能防止安装性能由于变速器的长度增加而恶化并且通过有效地降低变速器的输入轴的旋转振动（使用2-缸和3-缸发动机、降速或CDA）能够有效地抑制变速器的咔嗒声。
前述对本发明的具体示例性实施方案的描述是为了说明和例证的目的。这些描述并非想穷尽本发明，或者将本发明限定为所公开的精确形式，并且很显然，根据上述教导，可以进行很多改变和变化。对示例性实施例进行选择和描述的目的在于解释本发明的特定原理及其实际应用，从而使得本领域的其它技术人员能够实现并利用本发明的各种不同的示例性实施方案以及各种不同的选择和改变。本发明的范围意在由所附的权利要求书及其等同形式所限定。
