Description

具有多个起动器发动机装置的电动离合器
技术领域
本发明涉及一种离合器，该离合器包括：离合器盘；卡钳装置，该卡钳装置带有相对的摩擦垫，离合器盘位于这两个相对的摩擦垫之间，所述离合器盘以及卡钳装置每一个都与一输入部件和一输出部件中的其中一个相连；用于促使该相对的摩擦垫与该离合器盘进行摩擦接合的偏压装置；马达装置以及螺杆致动装置，该螺杆致动装置可以通过该马达装置驱动以便使得该相对摩擦垫能够克服偏压装置施加的偏压力而彼此产生相对位移。
发明背景
现在已经有了这样的离合器。所述现有的离合器的那种螺杆致动装置包括多个带有相应致动器的电动马达，这些电动马达沿着周向方向相对于该离合器盘均匀地间隔开。所述电动马达与该离合器一起进行旋转运动。这意味着必须通过一种旋转电接头(rotational electric connection)向所述马达传送电力，该旋转点接头通常采用滑环来实施。这样的设计方案既麻烦又容易产生故障。该滑环不可避免地会被磨损，并且这种磨损现象最终会损害该离合器的功能。
发明概述
因此，本发明的目的是为了提供一种前面所述类型的离合器，该离合器的设计较为简单并且更为可靠。该目的可以这样实现，即，该螺杆致动装置包括两个具有相对的螺纹的螺杆/螺母致动器，该螺杆/螺母致动器与该离合器盘同轴，每个致动器中的螺母和螺杆中的其中一个相对于该输入部件或输出部件可旋转地支承着，而每个致动器中的螺母和螺杆中的另一个与该相对的摩擦垫接合，该马达装置包括两个马达，每个马达都与该离合器盘同轴并且与一相应的螺杆/螺母致动器可驱动地相连。
通过适当地使得该螺杆/螺母致动器彼此相对旋转，可以使得该相对摩擦垫获得理想的位移量并因此在该离合器中获得理想的滑动量。该致动器的相对螺纹能够通过谨慎地选择该马达的旋转差可使得该相对摩擦垫彼此的相对位移限定得较为精确。
该马达可以具有固定定子，这意味着不需要供电所需的滑环。这使得其结构坚固而相对简单，并且可动部件更少，这样会增强该离合器的可靠性。该马达优选为电动型。
优选的是，该螺杆/螺母致动器具有彼此刚性相连的螺杆，所述螺杆与该相对摩擦垫啮合。马达和致动器之间的驱动连接可以采用几种方式来实施，例如，通过皮带或链条，但是优选的是采用齿轮驱动装置。这些齿轮驱动装置可以包括：与马达的转子相连的齿轮环；与该螺杆/螺母致动器的螺母相连的外部螺母齿轮；以及与该齿轮环和该螺母齿轮相啮合的中间齿轮，所述中间齿轮可旋转地支承在与该离合器盘同轴并且相对于该输入部件支承的质量块上。通过这些齿轮，也可以影响到传动比。
其上安装有该套中间齿轮的质量块的有利之处在于可以为其上安装有该离合器的发动机提供飞轮功能，该发动机优选为车辆内燃机。
根据本发明的另一个优点，该离合器可以用于这种车辆发动机的起动器形成一体。在这一点上，该质量块可以包括两个质量块，其中一个刚性地连接在该输入部件上而另一个相对于第一个质量块部件可旋转地支承着并刚性地连接在该卡钳装置上，所述质量块部件此外还通过切向定位的弹簧彼此啮合以便传递力矩，每个质量块部件都承载有其中一个齿轮驱动装置中一套中间齿轮。
通过以控制电动马达使其一致移动，可以将相应的旋转运动施加到该输入部件上，该旋转运动使得车辆内燃机得以起动。在两个质量半块之间的这种切向弹簧结构起到了通常的阻尼机构的作用以便抵抗在起动过程中产生的峰值力矩。
优选的是，该致动器的螺母通过相对于与该卡钳装置刚性连接的质量块部件相反定向的向心止推滚动轴承而可旋转地支承着。该偏压装置可以包括容纳在盲孔中并且与一压力板接合的压缩弹簧，该压力板上可以承载有该套摩擦垫。该致动器的螺杆可以与该压力板刚性连接，该压力板上可以承载有所述的那套摩擦垫，该卡钳装置具有一种向内延伸的支架，该支架上承载有相对的那套摩擦垫，并且该离合器盘可以沿轴向方向平移。该离合器盘的平移游隙可以补偿摩擦垫的磨损。
为了使得该离合器平衡，可以加入一静态或动态平衡单元。优选的是，采用一种自动平衡单元以便使得传动***中的振动最小化。
可以提供一外壳，马达装置的定子刚性的连接在该外壳上，所述外壳具有用于输入部件和输出部件的同轴相对开口。
电动马达的定子和转子还可用来在车辆发动机运转的时候发电(发电功能)。
该电动离合器(clutch by wire)的描述以及总成ISG涉及一种所谓的“中等(medium)”或“弱(mild)”混合驱动传动。在折中传动***概念中，电动马达在驱动状态下仅仅提供短暂的推进力矩。在一种所谓的“完全(full)”混合驱动传动中，该电动马达将车辆从静止状态下驱动到规定的速度，之后，电动马达关闭。随后，车辆的动力推动由相对较小的内燃机来承担。前面所述的电动马达包括一个用来起动该内燃机的小电动马达以及一个用来以如上所述方式驱动车辆的大电动马达。对于这两种类型的传动方式，电动马达可以包括永磁体型或电刷型，其转子与该离合器的中心线同心或成直角。当电动马达的旋转方向转向相反的方向时，就可以获得车辆的相反的驱动模式。
附图简要说明
下面将参照附图中所示的本发明的离合器的实施例对本发明进行描述，其中
图1所示的是该离合器的透视图，其中部分被切掉；
图2所示的是图1所示的离合器的径向剖视图。
具体实施方式
图1和2中所示的离合器包括外壳1，该外壳中容纳有两个同轴的电动马达2、3。所述电动马达分别与质量块6的质量块部件4、5接合。质量块部件4、5通过一体化的双列深槽滚珠轴承7而可彼此相对旋转。而且，该质量块部件可以通过多种均匀间隔开的切向弹簧8以一种已知的方式彼此啮合，这样，它们可以实现有限的相对旋转。
其中一个质量块部件，也就是质量块部件3，与一有轴向槽的输入轴套9相连，该轴套将与发动机(例如车辆发动机)相连。另一个质量块部件5与一卡钳装置10相连，该卡钳装置具有一支架11，该支架交叠在该离合器盘12上。该离合器盘12上承载有一管状驱动部件13，该驱动部件借助于例如花键与例如车辆等的手动或自动传动***相连。
该质量块部件5上设有一内部径向延伸的柱台14，两个相对的向心止推滚动轴承15、16支承在该柱台上。该滚动轴承15、16与两个螺杆致动器19、20上的螺母17、18分离或成一体，螺杆致动器19、20上还具有螺杆21、22。
螺母17、18以及螺杆21、22上具有相对的螺纹，并且通过滚珠(未示出)彼此啮合。该螺杆21、22与一可滑动的压力板23通过伸出部分33相连。借助于一花键/槽接头34，这些元件都不可旋转地彼此相对固定。在使螺杆21、22运动时，该抵靠部件33抵靠到压力板23上，并且随后使其移动离开支架11，以便使得离合器盘12和摩擦垫24、25彼此相对滑动，其与摩擦垫中的其中一套24啮合。相对的一套摩擦垫25与该支架11相连，该离合器盘12位于所述成套的摩擦垫24、25之间。
电动马达2、3每个都具有一定子26，该定子安装在该外壳上，固定在发动机外壳上或集成在具有配套的电动无级变速传动***(CVT by-wiretransmission)的外壳中。所述电动马达2、3的转子27每个都连接在独立的齿轮环28上。所述齿轮环28与一套中间齿轮29啮合，每个中间齿轮29都通过轴承20而相对各个质量块部件4、5支承着。螺母17、18具有外部齿轮31，该齿轮与相应的中间齿轮29啮合。除了齿轮外，也可以考虑采用链条或有齿皮带驱动装置。
所述的离合器可以采用下面描述的几种方式进行控制。第一种是，马达2、3可采用不同的旋转速度驱动，这样就通过相应的齿轮传动***28-31赋予螺母17、18不同的旋转运动。由于该相对定向的螺纹，压力板23沿轴向方向运动，由此改变离合器盘12和相对成套的摩擦垫24、25之间的摩擦啮合。因此，可以在输入部件9和输出部件13之间获得一种滑动、固定或自由相对关系。
在另一种实施例中，电动马达2、3可以一致地运动。因此，由于这种相对螺纹，可以赋予该输入部件9一种旋转运动。采用这种方式，所述的离合器可以起到发动机(例如与该输入部件9相连的车辆内燃机)的起动马达的作用。
根据第三种实施例，该电动马达2、3可以起到一种发电机的功能。当与该输入部件9相连的发动机运转时，转子27相对于该相应的起动器26一致地运动，这样通过一种适当的电动控制可以产生电流。
总而言之，本发明的离合器可以起到摩擦离合器、起动马达以及发电机的功能。
电动马达2、3可以具有永磁体，或者可以是电刷类型马达。这些电动马达2、3的转子27可以与该离合器轴线同轴，或者可以与该离合器轴线成直角。电动马达2、3的外壳可以是具有发动机壳体的一体化部分，该发动机壳体上连接有该离合器。而且，这些电动马达外壳可一体形成在该传动装置中或集成在一中间壳体中。
所述离合器可以用于所述的自动目的，但是也可用于车床、挖掘机、磨床等工业领域。
该离合器的元件可采用金属、非金属或复合材料制成，并且可以采用冷成型、铸造或模制工艺制成。
需要指出的是，压力板23不能相对于摩擦垫24和质量块5旋转。
所述的离合器可以无级变速传动***的一部分，该无级变速传动***包括可采用电致动的无级变速传动***以及可以采用电致动的正/反驱动***。或者，该离合器可以是汽车的手动挡传动***或一种自动齿轮传动***。
