发明内容
本发明的任务是有利地扩展具有旋转振动减振器和离心力摆的离合器盘。尤其要改进离合器盘相对于旋转振动的振动隔离。尤其要改进离合器盘对预给定的应用的适应性。
该任务通过权利要求1的主题来解决。从属权利要求又给出权利要求1的主题的有利实施方式。
提出的离合器盘设置用于安装在摩擦离合器中。摩擦离合器能够用作内燃机和变速器之间的驱动系的分离离合器。摩擦离合器能够安装在混合驱动系中、在具有手动切换或自动切换的变速器的驱动系中。在本发明的意义中具体包括:具有提出的离合器盘的摩擦离合器;具有飞轮的扭矩传递装置,该扭矩传递装置尤其具有双质量飞轮、摩擦离合器和提出的离合器盘尤其作为结构单元。尤其能够在扭矩传递装置中设置具有提出的离合器盘的减振设计,在该减振设计中,在初级飞轮质量和次级飞轮之间设置有摩擦离合器、至少一个旋转振动减振器和至少一个离心力摆,其中,旋转振动减振器和离心力摆以提出的方式布置在离合器盘中。
提出的、绕旋转轴线(例如摩擦离合器的旋转轴线)以能扭转的方式布置的离合器盘为此包括旋转振动减振器,例如具有输入部件和输出部件的扭振减振器。沿周向方向在输入部件和输出部件之间起作用地布置有弹簧装置。输入部件优选地接收径向外部的摩擦衬片,用于构成与摩擦离合器的相应的配对摩擦面的摩擦锁合,并且因此用作衬片载体。输入部件能够由单个的、构造为法兰部件的衬片载体构成。输入部件能够由轴向间隔开的并且例如借助间隔销栓相互连接的两个法兰部件构成,其中,所述法兰部件中的一个构造为衬片载体。输入部件在输入侧加载弹簧装置。输出部件能够由与轴(例如变速器输入轴)旋转锁合地连接的毂和与所述毂有扭转间隙地或没有扭转间隙地连接的至少一个法兰部件构成。在设置有扭转间隙的情况下,能够通过至少一个法兰部件和毂之间的扭转间隙的扭转角度起作用地布置另一弹簧装置作为怠速减振器。输出侧的所述至少一个法兰部件能够轴向地在单个的输入侧法兰部件(如衬片载体)旁布置。在轴向间隔开的输入侧的两个法兰部件中,一个或多个输出侧法兰部件能够轴向地布置在两个输入侧法兰部件之间。所述至少一个法兰部件在输出侧加载弹簧装置,使得在输入部件和输出部件相互扭转时,压缩所述弹簧装置的弹簧元件并且接收能量并且在反向扭转时又释放能量。在输入部件和输出部件之间的相对扭转的至少一部分上能够起作用地设置摩擦装置。
弹簧装置由至少两个相继连接的弹簧元件构成,其中,在两个弹簧元件之间布置有中间法兰。在此,第一弹簧元件能够被输出部件和中间法兰加载,并且第二弹簧元件能够被中间法兰和输出部件加载。中间法兰能够轴向地布置在两个输出侧法兰部件之间或在单个的输出侧法兰部件的情况下在轴向上与所述输出侧法兰部件间隔开地布置。
根据一个有利的实施例,第一和第二弹簧元件在之间连接有中间存储装置的情况下布置在两个输出侧法兰部件之间。所述输出侧法兰部件具有扭转间隙地接收在毂上。所述输入部件根据转矩方向(牵引或滑动负荷)加载两个输出侧法兰部件中的一个,其中,该输出侧法兰部件被在法兰部件和毂之间在周向方向上具有扭转间隙地构造的齿抬起,而另一法兰部件通过齿将通过弹簧装置传递的转矩传递到毂上。
弹簧元件能够由在周向上布置的螺旋压力弹簧、碟形弹簧组、弹性体块和/或类似装置构成。多个螺旋压力弹簧能够能够在径向上相互嵌套并且因此构成弹簧元件。相互嵌套的螺旋压力弹簧能够不同长度地构造,以便构成弹簧元件相对于输入和输出部件的扭转角度的弹簧力的多级弹簧特性曲线。替代地或附加地,能够在不同的周向上布置输入部件、输出部件和/或中间法兰的加载装置,用于加载在径向时相互嵌套的螺旋压力弹簧,使得所述螺旋压力弹簧中的一部分在比相互嵌套的螺旋压力弹簧的其它部分更小的扭转角度时被加载。第一和第二弹簧元件或者说属于所述弹簧元件的螺旋压力弹簧能够具有相同或不同的刚度。不同地构造第一和第二弹簧元件的刚度尤其能够在牵引和滑动方向中对离合器盘不同要求的情况下是有利的。
提出的离心力摆具有绕离合器盘的旋转轴线布置的摆质量载体。在该摆质量载体上能摆动地接收摆质量在摆轨上,所述摆质量在周缘上分布地布置。摆质量载体能够构造为摆法兰,在该摆法兰上在两侧接收摆质量,其中,在轴向上相对置的摆质量借助贯穿摆法兰的连接器件相互连接成摆质量单元。替代地,摆质量载体能够由两个轴向相互并排地布置的并且以优选的方式相互连接的侧部件构成,所述侧部件具有轴向扩展的摆区段,所述摆质量能摆动地接收在该摆区段中。
提出的离合器盘具有离心力摆,其摆质量载体与中间法兰抗扭转地耦合。为了使摆质量载体和与该摆质量载体连接的中间法兰定心,摆质量载体定心地接收在输出部件上。在此,中间法兰以有利的方式以其低的转动惯量减振。
根据离合器盘的一个有利实施方式,在输出部件的毂上设置轴向区域,如凸出部,摆质量载体以能受限扭转的方式并且定心地接收在该轴向区域中。
在摆质量载体和输出部件、例如该输出部件的毂之间能够布置摩擦套筒。该摩擦套筒能够抗扭转地布置在摆质量载体上或毂上,并且借助相对于该毂能扭转的配对摩擦面构成摩擦装置。替代摩擦套筒能够设置滑动套筒,该滑动套筒减小在摆质量载体和输出部件之间的摩擦。替代地,能够在摆质量载体和输出部件之间设置滚动轴承或滑动轴承。
根据离合器盘的一个有利实施方式,旋转振动减振器和离心力摆能够在轴向上相互并排地布置。在一个替代的实施方式中,旋转振动减振器和离心力摆能够相互嵌套地构造。例如,中间法兰能够构造为摆质量载体。在此,离心力摆的摆质量能够在旋转振动减振器的弹簧元件的径向外部或者径向内部布置。替代地,摆质量能够在轴向上相邻于弹簧元件以基本上相同的直径布置。
在旋转振动减振器和离心力摆的轴向并排地设置的结构方式中,摆质量载体能够借助在轴向上定向的、贯穿输入部件(尤其衬片载体的法兰部件、尤其衬片载体)的间隔栓与中间法兰连接。所述间隔栓的贯穿在槽口处实现,例如在输入部件的弯曲长形孔处实现,以便允许中间法兰和输入部件之间的相对扭转。在此,间隔栓在槽口的周向限界的壁上的止挡限制输入部件和输出部件之间的扭转角度。
为了防止径向地位于旋转轴线上方的摆质量尤其在离合器盘静止或以低转速转动时径向向内地移位,摆质量能够借助在径向上起作用的弹簧元件、例如相对于摆质量载体的螺旋压力弹簧来支撑。
提出的离心力摆能够例如类似于在未公开的、就此完全引用到本申请中的德国专利申请(申请号10 2014 206 254.7)中的所述离心力摆来构造。与这个离心力摆不同地,提出的离心力摆以能扭转的方式并且定心地连接在输出部件的毂上并且与该毂没有抗扭地连接。在这方面,提出的离心力摆配属于中间法兰而不配属于输出部件。

输出部件3由两个法兰部件10、11构成,所述法兰部件借助齿13在构造有扭转间隙14的情况下抗扭转地与毂12连接。轴向地在两个法兰部件10、11之间浮动地布置中间法兰15。
弹簧装置16由第一弹簧元件17和第二弹簧元件18构成,所述弹簧元件分别接收在法兰部件10、11中的一个和中间法兰15之间并且被它们在周向方向上加载。在这里所示的实施例中,弹簧元件17、18由相互嵌套的螺旋压力弹簧19、20构成。
输出侧的法兰部件10、11根据引入到输入部件2或者输出部件3中的转矩互换地加载并且通过弹簧元件16借助中间法兰15传递所施加的转矩到输出部件3或者输入部件2上。在牵引阶段,转矩通过摩擦衬片8传递到输入部件2上。输入部件2的间隔栓9止挡在法兰部件10、11中的一个上,使得该法兰部件加载弹簧装置16。通过弹簧元件17、18和中间法兰15将转矩传递到另一输出侧法兰部件11、10上,该另一输出侧法兰部件止挡在齿13上并且传递转矩到毂12上。在滑动阶段,转矩以相反的方式由毂12传递到摩擦衬片8上,其方式是,法兰部件11、10中的一个通过止挡在齿13上将转矩传递到弹簧元件17、18上并且通过中间法兰15传递到另一法兰部件10、11上,所述另一法兰部件止挡到间隔栓9上,使得通过所述间隔栓传递转矩到法兰部件6、7上并且最后传递到摩擦衬片8上。
法兰部件6、7在中间置有塑料衬套21、22的情况下定心在毂12上。中间法兰15相对于毂12浮动地布置。中间法兰15借助在轴向上贯穿法兰部件10和法兰部件6的槽口24、25的间隔栓26与摆质量载体23固定地连接。槽口24、25这样构造,使得能够实现中间法兰15相对于法兰部件6、10的不受干扰的扭转。
摆质量载体23由借助间隔栓27在轴向上隔开地相互连接的两个侧部件28、29构成。侧部件28、29在自身之间接收在周缘上分布地布置的摆质量30,所述摆质量以已知的方式借助摆轴承相对于摆质量载体23在离心力场中能摆动地在构造有转速适应的旋转振动吸振器的情况下被接收。例如由塑料制成的摩擦套筒31接收在侧部件28、29的内周向上,借助该摩擦套筒,摆质量载体23定心在毂12的轴向凸出部32上并且以能受限扭转的方式被接收。通过间隔栓26,本来浮动地接收的中间法兰15同样定心在毂12上。
摆质量30在足够的离心力时向径向外部加速并且借助其摆轴承能摆动地支撑在侧部件28、29上。如果离心力由于离合器盘1的低转速而减小或该离心力在离合器盘1静止时为零,则分别在径向上位于旋转轴线d上方的摆质量30向径向内部支撑。为此,摆质量30向径向内部借助在径向上起作用的弹簧元件33(如螺旋压力弹簧)支撑。
离心力摆5振动隔离地接收在弹簧元件17、18之间,使得除摆质量30外相关的转动惯量仅通过摆质量载体23、间隔栓26、27和中间法兰15构成。
图2在剖面视图中示出图1的离合器盘1。由输入部件2仅示出具有摩擦衬片8和间隔栓9的法兰部件6。所述间隔栓9部分地具有周向间隙地贯穿中间法兰15的槽口34并且沿转矩方向在所示的用于法兰部件11的运行位置中分别构成用于输出侧的法兰部件10、11的止挡装置35。由螺旋压力弹簧19、20构成的两个正好相对置的弹簧元件17、18分别被接收(例如轻微地预紧)在法兰部件10与中间法兰15之间和在法兰部件11与中间法兰15之间。法兰部件10、11借助具有扭转间隙的齿13被旋转锁合地接收在毂12上。中间法兰15借助间隔栓26与离心力摆5的不可见的摆质量载体23(图1)固定地连接。
图3在分解示图中示出具有离心力摆5的离合器盘1。离心力摆5由摆质量载体23和摆质量30构成。摆质量载体23由两个侧部件28、29构成,所述两个侧部件借助间隔栓26相互在轴向上间隔开地连接。摆质量30借助弹簧元件33向径向内部地支撑。借助接收在侧部件28、29上的摩擦套筒31,摆质量载体23定心地接收在毂12的轴向凸出部32上。离心力摆5借助间隔栓26与中间法兰15固定地连接。输出侧的法兰部件10、11置于中间法兰15两侧并且有扭转间隙地接收在毂12的齿13上。弹簧元件17、18分别在两个法兰部件10、11中的一个与中间法兰15之间以能预紧的方式被接收并且由螺旋压力弹簧19、20构成。法兰部件7和具有摩擦衬片8的法兰部件6借助间隔栓9相互连接并且借助塑料衬套21、22定心在毂12上。
图4示出图1至3的离合器盘1的原理连接图。在离合器盘1的牵引阶段中,通过摩擦离合器和摩擦衬片沿箭头36方向传入到离合器盘1中的转矩由输入部件2通过止挡装置35传递到法兰部件10上。该法兰部件被毂12的齿13抬起并且加载具有弹簧元件17的弹簧装置16、中间法兰15和弹簧元件18。弹簧元件17、18的刚度可以是相同的或不同的。弹簧元件17、18的特征曲线可以是一级的或多级的。转矩被传递到法兰部件11上。该法兰部件在齿13上进入与毂12的形状锁合,使得沿箭头37的方向将被旋转振动减振器4和离心力摆5的振动隔离的转矩传递到变速器输入轴上。离心力摆5由于其摆质量载体和中间法兰15的低的质量而具有低的转动惯量或者具有摆质量30相对于不摆动的质量的有利质量比,所述离心力摆具有在平面内垂直于离合器盘1的旋转轴线沿着双箭头38振动的摆质量30。在输入部件2和毂12之间设置有摩擦装置39,该摩擦装置例如能够通过布置在摆载体和毂12之间的摩擦套筒构成。在与箭头36、37相反的滑动方向中,毂12在弹簧装置16负荷的情况下携动法兰部件11。借助法兰部件10将通过弹簧装置16引导的转矩通过止挡装置35传递到输入部件2上。
