Description

变速箱离合器的摩擦阻尼器
发明领域
本发明总体上涉及自动变速箱离合器轮毂的摩擦阻尼器。
背景技术
在机动车自动变速箱的常规运行模式下，车辆乘员可能会听到或者感觉到令人厌恶的噪音及振动，这些噪音及振动通过由花键连接到离合器摩擦片上的离合器轮毂传递。
这些噪音产生于扭转振动，该扭转振动来自自动变速箱发生挡位变换时摩擦离合器啮合与解离过程中的粘着滑动（stick slip）。当前挡位向新挡位的转换通常涉及到：解离离合器，产生当前齿轮比需要该离合器的啮合；以及啮合第二离合器，产生新的挡位需要该第二离合器的啮合。由于离合器滑动，离合器的啮合与解离可能导致离合器自激（self-excitation）。
发明内容
一种离合器总成包括：可以绕轴线旋转并且至少部分环绕空腔的轮毂；可以绕轴线旋转并相对于轮毂可旋转的位于空腔内的阻尼环；弹簧；由弹簧弹性地推动至接触阻尼环的摩擦盘；以及接触阻尼环并且提供对弹簧力的反作用力的第二摩擦盘。
在离合器轮毂的旋转振动过程中，大部分阻尼环相对离合器轮毂旋转。结合到离合器轮毂的摩擦阻尼器通过消除共振来减少轮毂振动。
摩擦阻尼器不是将离合器轮毂用作摩擦表面，而是将传统的摩擦片用作阻尼器摩擦元件并将其大部分用作摩擦表面。
摩擦阻尼器装配到离合器轮毂之后，在不拆卸阻尼器的情况下，将离合器轮毂压入到轴。
通过下面的详细说明，权利要求以及附图，优选实施例的应用范围将变得显而易见。应该了解的是，虽然这些说明和具体实例指出了发明的优选实施例，但其仅以示例方式给出。对所属领域的技术人员来说，所述实施例和实例的各种变化和修改是显而易见的。
附图说明
通过参考以下结合附图的描述，将更容易理解本发明，其中：
图1是安装在机动车自动变速箱内的摩擦离合器总成的横断面视图；
图2是图1的离合器轮毂的侧视图；以及
图3是图1的摩擦阻尼器总成的横断面视图。
具体实施方式
如图1所示，车辆自动变速箱的离合器总成10以及相关组件包括离合器轮毂14，该轮毂绕由花键19固定到轮毂的轴18的轴线16旋转。离合器10的一组摩擦盘20中的每一个均由轴向花键固定于轮毂14上。在摩擦盘20之间交错的一组隔板24中的每一个均由轴向花键25固定于外壳22的径向内表面上。支承离合器活塞26以进行轴向位移。密封汽缸28内的液压驱动活塞26向右移动，因此推动摩擦盘20和隔板24彼此摩擦接触并支靠于背板30，该背板由止动环（snap ring）32固定于外壳22上以防止位移。螺旋弹簧34连续地向左推进活塞26。加压的液压流体经由径向通道35供给到汽缸28。
经由径向通道38充满液压流体的空间36在空间36的右侧封闭并且由平衡坝（balance dam）40在此密封。
离合器阻尼器44包括位于空腔46内的环形阻尼环52。液压流体经由轴承53，经由摩擦盘54和阻尼环52之间的界面、空腔46、轮毂14上一系列的径向孔48，供给到离合器10的摩擦盘20。随着离合器轮毂14绕轴线16旋转，离合器阻尼器44绕轴线16旋转。位于阻尼环52的右侧的摩擦盘54包括摩擦材料55，由盘形弹簧58的弹力将该摩擦材料55向左弹性推进至接触阻尼环52的轴向面56，该盘形弹簧轴向位于离合器轮毂14和摩擦盘54之间。第二摩擦盘60固定在离合器轮毂14上，该第二摩擦盘包括接触阻尼环52左侧轴向面62的摩擦材料61。
阻尼环52位于环形空腔46内，该空腔由平衡坝40和轮毂14的径向部分66轴向地界定，并由离合器轮毂14和外壳22的轴向部分68径向地界定。优选地，阻尼环52由固体金属形成。
空腔46内的液压流体被引导到阻尼环52右侧轴向面56上的摩擦盘54上的摩擦材料55之间，以及阻尼环52左侧轴向面62上的第二摩擦盘60上摩擦材料61之间。
当离合器总成10内发生旋转振动时，阻尼环52绕轴线16旋转并且相对离合器轮毂14旋转。阻尼环52的轴向面56和摩擦盘54之间以及阻尼环52的轴向面62和第二摩擦盘60之间的相对位移经由摩擦消耗能量，因此最小化离合器总成10内的振动并减少噪音。摩擦阻尼环52通过消除共振来减少离合器轮毂14的振动。
采用独特的紧固技术将阻尼环52结合到离合器轮毂14内，依靠此技术，摩擦阻尼器装配到离合器轮毂14内之后，在不拆卸阻尼器的情况下将离合器轮毂压入到轴18。
按照专利法规定，已经描述了优选实施例。但是，应该指出的是，除了具体说明和描述的实施例以外的替换实施例也能够被实施。
