Description

用于混合动力模块和驱动系的混合动力减振器对中解决方案
技术领域
本发明涉及一种用于机动车(例如载客车、载重车或其他商用车)的驱动系的混合动力模块，该混合动力模块具有电机，该电机具有转子，其中，在转子和从动轴之间的扭矩流中布置有(次级)扭转振动减振器，该(次级)扭转振动减振器径向对中地布置在转子上、优选布置在该转子的内部区域上和/或径向对中地布置在从动轴上、优选布置在该从动轴的外部区域上。
发明内容
本发明的任务是提供一种具有特别良好的扭转振动减振特性的混合动力模块，所述扭转振动减振特性符合噪声-振动-声振粗糙度方面的高要求，能够成本低廉地实施，耐用并且同时实现巧妙的对中方案。
该任务在相应的混合动力模块中通过以下方式解决：(次级)扭转振动减振器(自身)有针对性地设计为用于补偿轴线偏移和/或角度偏移。
因此，提出了特别巧妙的对中方案，用于混合动力模块上的减振器。在此，能够间接地或直接地在转子中、优选齿侧对中地通过齿部实现减振器输入部件的对中。能够直接地或间接地、例如通过毂实现减振器输出部件在输出轴上的对中。在此，减振器输出部件能够固定地与所述毂连接或者在周向方向上可运动地对中。
在从属权利要求中要求保护有利的实施方式并且在下面详细地阐明所述有利的实施方式。
因此，有利的是，(次级)扭转振动减振器由下述构件构成，所述构件相互匹配为使得在所述构件的至少两个构件之间存在径向间隙。在此，尤其有效地补偿了从动轴的旋转轴线与转子的旋转轴线的不对准，而不会在使用寿命期间显示出大的磨损。
在这种情况下也已经证明有效的是，(次级)扭转振动减振器具有附接在转子上的扭矩传递器/扭矩输入部件，所述扭矩传递器/扭矩输入部件相对于与从动轴连接的扭矩传递构件/扭矩输出部件具有径向间隙和/或轴向间隙。在此，能够有效地避免研磨和摩擦的噪音。这有利于磨损特性。
为了实现精确的对中，经证明有效的是，扭矩传递构件对中地贴靠在从动轴的外表面上或对中地贴靠在中间连接的毂上。
当扭矩传递构件或毂具有与从动轴的外齿部形状锁合的内齿部时，也能够传递特别高的扭矩。在此，实施齿侧对中经证明尤其有效。
有利的实施方式的特征也在于，(例如具有在轴向方向上隔开的凸缘的)扭矩传递构件或者毂通过存在于从动轴的周向槽中的(例如按照锁环的类型的)轴向止挡环和/或通过安装在转子上的止挡而固定在所述扭矩传递构件的/所述毂的轴向位置中。
此外实用的是，所述止挡构型为安装在转子内周缘上的盘。
此外，经证明有效的是，扭矩传递器的径向内端部贴靠在扭矩传递构件、毂和/或从动轴上(例如其端侧上)或与其尤其轴向地或径向地间隔开。
当(次级)扭转振动减振器中安装有(压力/螺旋)弹簧、例如弧形弹簧时，优选地，在这些弹簧的端部上放上端盖，所述端盖提供用于相应的弹簧操纵器(例如铆接在扭矩传递器的转子部件上的减振器部件)的贴靠面，因此能够借助成本低廉的构件实现子组件的有效运行。
本发明也涉及一种驱动系，其具有第一驱动设备、例如构造为内燃机的驱动设备，其中，在第一驱动设备与由根据本发明的类型的混合动力模块的电机提供的第二驱动设备之间的扭矩流中存在(初级)扭转振动减振器，并且优选地，在所述(初级)扭转振动减振器与电机的转子之间布置有(例如按照多片式离合器或多盘式离合器的类型的)分离离合器/摩擦离合器。
借助所提出的对中方案补偿转子与输出轴/从动轴之间的位置误差、即尤其轴线偏移和角度偏移，其中，尤其在减振性和不平衡性方面确保减振器或设备的装配和功能。能够间接地或直接地在转子中、优选齿侧对中地通过齿部进行减振器输入部件的对中。经验证的是，直接地或间接地、例如通过毂实现互补的减振器输出部件在输出轴上的对中。在此，减振器输出部件能够与毂固定地连接或者在周向方向上可运动地对中。在此，作为对中有意义的是，径向间隙小于0.5mm、优选地小于0.3mm、尤其小于0.15mm。
因此，能够至少部分地在减振器内实现偏移补偿或角度补偿。在此，减振器输入部件和减振器输出部件相对彼此移位。如果减振器输入部件在结构上附加地具有相对于输出轴(例如间接地通过毂)的径向定位，那么该径向间隙大于减振器输出部件与输出轴或毂之间的径向间隙，有利地大于0.2mm、更有利地大于0.5mm。如果设置有另一减振器、即(初级)扭转振动减振器，则也能够根据对输出轴的上述定义集成(初级)扭转振动减振器。
应指出的是，如果在力流中紧跟在转子之后的减振器是弧形弹簧减振器，则弧形弹簧能够优选地配备有端盖，用于在减振器输入部件和减振器输出部件之间有径向偏移的情况下改善弹簧操纵，所述端盖也能够称作端帽(End-Cap)。由此能够实现特别巧妙的混合动力减振器组合。因此，减振器中的补偿是强制执行的。

图6安装在(次级)扭转振动减振器中的弧形弹簧的横截面示图，该弧形弹簧具有作用在其上的端盖。
附图仅是示意性的性质并且仅用于理解本发明。相同的元件设置有相同的附图标记。单独的实施例的特征能够互换。尤其能够在图1和2和5的实施方式中使用如图6中示例性地示出的弧形弹簧和端盖。替代地，图2的实施方式也能够适应内部没有对中的情况。
具体实施方式
图1中示出了根据本发明的混合动力模块1的第一实施方式。混合动力模块1具有电机2，该电机具有转子3，该转子能够以转动运动的方式移动。在此，由转子3提供的扭矩传递到(次级)扭转振动减振器4上。(次级)扭转振动减振器4与从动轴5连接。
电机2是第二驱动设备，相对于安装混合动力模块1的驱动系中的第一驱动设备，附加地使用该第二驱动设备。在此，第一驱动设备、即内燃机将扭矩传递到曲轴6上。曲轴6与(初级)扭转振动减振器7连接。该(初级)扭转振动减振器7将扭矩传递到驱动轴8上，驱动轴8与构造为摩擦离合器的分离离合器9连接。按照多片式离合器10的类型构造该分离离合器9。
转子3在其内侧上具有齿部11。在该齿部中插入多片式离合器10的片12。在片12和(次级)扭转振动减振器4的扭矩传递器13之间存在止挡14。
扭矩传递器13分为转子部件15和减振器部件16，这两个部件通过铆接连接部17彼此连接。
在此，减振器部件16作为弹簧操纵器18起作用并且(如图6所示，例如在中间连接有端盖21的情况下)作用到弹簧19、即弧形弹簧20上。回到图1应指出的是，(次级)扭转振动减振器4分为前减振器22和后减振器23。前减振器22布置在后减振器23的径向外部。
(次级)扭转振动减振器4、尤其后减振器23具有扭矩传递构件24，该扭矩传递构件作用到毂25上。存在与毂25轴向间隔开的轴向止挡环26。
自然在图1和图2的实施例中，电动机也具有定子27。
然而，与根据图1的实施方式不同，根据图2的实施方式不具有两件式的(次级)扭转振动减振器4，而是仅具有一个单级减振器。扭矩传递器13、尤其该扭矩传递器的减振器部件16终止于毂25的径向内部但与该毂径向地间隔开，从而设置有径向间隙27。与该径向间隙相邻地存在止挡盘28。
在图3的实施方式中可见，扭矩传递构件24的内面对中地贴靠在从动轴5的外面30上。毂25具有内齿部31，该内齿部以形状锁合的方式与从动轴5的外齿部32齿侧对中地贴靠。
图4中所示的扭矩传递构件24具有在轴向上间隔开的凸缘33。
在图5中，扭矩传递器13的、尤其转子部件15的径向内端部34布置在毂25的径向内部，但只向内拉伸到使得该端部与从动轴5的端面35相邻的程度。
图6中标明了安装到弧形弹簧20中的端盖21在与钩、例如弹簧操纵器18共同作用时的减少磨损的共同作用。
