附图说明
下面参照附图详细地描述本发明。具体地：
图1：示出了本发明的具体实施方式中的扭矩传递装置的横截面。
图2：示出了本发明的又一具体实施方式中的扭矩传递装置的横截面的细节。
具体实施方式
图1示出了本发明的具体实施方式中的扭矩传递装置10的横截面。扭矩传递装置10布置在车辆的传动系中并且引起在此未示出的第一驱动元件与在此也未示出的输出端元件之间的扭矩传递。第一驱动元件可以是内燃发动机，并且输出端元件可以是传动装置。
扭矩传递装置10包括扭矩传递单元12，该扭矩传递单元具有隔板14以及用于界定第一流体室18的壳体16，第一流体室特别地可以完全填充有液体。扭矩传递单元12包括扭矩变换器20，扭矩变换器又具有扭矩变换器壳体22，扭矩变换器壳体至少部分地形成壳体16。用作第二驱动元件28的电动马达26的转子24紧固至扭矩变换器壳体22。转子24可相对于定子30旋转，其中，定子30紧固至传动装置壳体32。壳体16布置在传动装置壳体32内。扭矩传递单元12连接至输出端34，在此是布置在扭矩变换器20内的扭转振动阻尼器36的阻尼器输出端毂，特别地经由传动装置输入轴38与输出端元件连接。
在扭矩传递单元12和第一流体室18外侧，用于在第一驱动元件与扭矩传递单元12之间选择性地传递扭矩的分离式离合器42布置在与后者以流体密封的方式分离的第二流体室40中。分离式离合器42被设计成干式的，并且第二流体室40没有液体。在分离式离合器42与第一驱动元件之间布置有扭转振动阻尼器44，扭转振动阻尼器具有连接至第一驱动元件的阻尼器输入端46以及阻尼器输出端50，阻尼器输出端可以通过弓形弹簧48的作用而相对于阻尼器输入端46旋转至有限的程度，并且阻尼器输出端经由连接毂54和输入多盘承载件56连接至分离式离合器42的离合器输入端52。为此目的，阻尼器输出端50以在旋转方面固定的方式连接至连接毂54，并且连接毂又经由允许轴向位移的齿形件连接至输入端多盘式承载件56。
输入端多盘式承载件56以在旋转方面固定的方式与至少一个摩擦盘58连接，在此为铆接，至少一个摩擦盘是分离式离合器42的摩擦装置60的一部分。摩擦盘58在两侧都具有摩擦衬里62，摩擦衬里可以摩擦地连接至离合器输出端64，离合器输出端具有端部盘66、可轴向移位的按压元件68以及用于传递第一驱动元件的驱动扭矩的输出端多盘式承载件70。
输出端多盘式承载件70连接至离心摆72。离心摆72具有摆质量件承载件74，在摆质量件承载件上接纳有至少一个摆质量件76，使得摆质量件可以沿着摆路径偏转至有限的程度。摆质量件承载件74在此特别地铆接至输出端多盘式承载件70。
输出端多盘式承载件70经由固定环80轴向地固定在连接部件78上并且以径向居中的方式被接纳。连接部件78刚性地连接至变换器壳体22。扭矩传递单元12经由连接部件78和固定在连接部件上的支撑轴承82被支撑在隔板14上。此外，在连接部件78与隔板14之间布置有密封装置84。隔板14牢固地连接至传动装置壳体32，在此为旋拧到传动装置壳体中。
按压元件68经由齿形件以在旋转方面固定的方式连接至传动元件86。连接部件78和传动元件86以在旋转方面固定的方式连接至彼此并且可相对于彼此轴向地移位。传动元件86可以经由轴承88相对于连接毂54旋转。传动元件86以及连接部件78以在旋转方面固定的方式连接至离合器输出端64并且传动元件以及连接部件两者同时或仅传动元件86单独地可以将来自第一驱动元件的扭矩引入到扭矩传递单元12中并且因此形成扭矩传递单元12的可围绕旋转轴线A旋转的输入端90。连接部件78的在扭矩传递中的部分在此特别地通过输出端多盘式承载件70与连接部件78之间的连接的扭矩传递能力来测量。
传动元件86布置在连接部件78的径向内侧。两个密封元件92径向布置在传动元件86与连接部件78之间，两个密封元件将第一流体室18和第二流体室40彼此密封隔离。可轴向移动的传动元件86在隔板14的内侧径向地延伸穿过壳体16并牢固地连接至致动元件94。致动元件94被分配给分离式离合器42的离合器致动装置96。离合器致动装置96包括致动元件94、连接部件78和按压元件68。
致动元件94可以具有被施加在致动元件上的流体压力并且基于该流体压力可轴向地移动。按压元件68将致动元件94的致动力传递至摩擦装置60以产生离合器输入端52与离合器输出端64之间的摩擦连接。因此，作用在压力室98中的致动元件94上的流体压力致使致动元件94在分离式离合器42的方向上的轴向偏转。致动运动通过传动元件78传递至按压元件68。按压元件68将致动力引导到摩擦装置60中以用于关闭分离式离合器42，这从而产生用于离合器输入端52与离合器输出端64之间的扭矩传递的摩擦连接。
致动元件94连接至复位元件100，复位元件具有多个板弹簧并且复位元件牢固地连接至变换器壳体22。如果压力室98中用于关闭分离式离合器42的流体压力低于预定值，则致动元件94被复位元件100移动到以下初始位置：在所述初始位置中，分离式离合器42打开并且离合器输入端52和离合器输出端64可以相互旋转并且分离式离合器42中断扭矩传递。
按压元件68布置在第一流体室18的外侧并且布置在第二流体室40的内侧，并且致动元件94布置在第一流体室18内以用于通过流体压力施加压力。因此，由于与液体接触，特别是由于从第一流体室18泄漏流体，分离式离合器42的功能受损的风险能够被降低。
由离合器致动装置96产生的用于关闭分离式离合器42的致动力由连接部件78承受。在这种情况下，当分离式离合器42被致动时，经由传动元件86和连接部件78产生闭合的力流。致动元件94和按压元件68布置成彼此轴向地间隔开并且径向地重叠。隔板14布置在由致动元件94和按压元件68形成的轴向的中间空间102中，支撑轴承82布置在该轴向的中间空间中。
扭矩变换器20具有变换器锁止离合器104，变换器锁止离合器具有连接至变换器壳体22的离合器输入端106。变换器锁止离合器104的离合器输出端108连接至扭转振动阻尼器36的阻尼器输入端110。阻尼器输出端毂34可以经由至少一个压缩弹簧112的作用而相对于减振器输入端110旋转至有限的程度。阻尼器输入端110连接至涡轮114，涡轮可以经由存在于第一流体室18中的液体通过连接至转换器壳体22的泵116实现扭矩传递。
图2示出了本发明的又一具体实施方式中的扭矩传递装置10的横截面的细节。第二流体室40可以具有与第一流体室的液体分离的液体。该液体可以导致分离式离合器42的喷雾冷却。第二流体室40经由连接至传动装置壳体32的盖板118以液密的方式密封隔离。密封件122附接在连接至阻尼器输入端46的驱动毂120与盖板之间。
