Description

带有可传递扭矩的齿轮的混合动力模块
技术领域
本发明涉及一种适用于(混合动力)机动车的混合动力模块，所述混合动力模块带有驱动机，例如电机或内燃机，它以可传递扭矩的方式与例如用内燃机或电机驱动的扭矩输入轴或扭矩输出轴(下文简称为扭矩输入轴)、例如变速器输入轴或曲轴相连，其中，所述驱动机的输出轴或驱动轴(下文简称为输出轴)以轴向平行于扭矩输入轴的方式布置。
背景技术
通过背景技术已知一种带有以轴向平行方式布置的驱动机的混合动力模块。例如，DE 10 2016 212 846 A1公布了一种适用于带有电机或内燃机的机动车动力总成***的离合装置，其扭矩可通过离合单元被传递到变速器，其中，在准备用于将电机扭矩朝离合单元方向传导的耦合机构与内燃机侧可驱动的传递机构之间布置了一个分离离合器，其中，电机按如下方式布置，即：其旋转轴与离合单元构件在工作中转动时所围绕的旋转轴不对齐，其中，使用一个被设计成链条的无限牵引机构将扭矩从电机传递到耦合机构。
混合动力模块通常按如下方式设计，即：它与内燃机和变速器钟罩拧在一起。其它接口用于连接内燃机的曲轴、电机以及空调压缩机。在混合动力模块中集成有减振器、离合器和执行器***。另外，混合动力模块注有油，以便能够冷却离合器并润滑布置在混合动力模块内部的构件。离合器用于将内燃机与变速器和电机以可耦合的方式相连，它还被称为分离离合器K0。电机以轴向平行于曲轴或变速器输入轴的方式布置。电机和离合器或变速器输入轴构成一个主动力总成***，它们通常通过设计成齿链的主链条传动装置相连。另外，空调压缩机还可以通过被设计成齿链的副链条传动装置与电机相连。作为连接轴向平行混合动力模块的替代方案，还会使用齿带、多V型皮带或三角皮带。
但背景技术始终具有如下缺点，即：在按上述通过链条传动装置连接主动力总成***的***中，会根据电机与变速器输入轴之间的传动比出现高链条速度，这会不利地导致链条的高负荷，例如因摩擦或离心力。因此，链条是重要构件。另外，链条的使用还会导致产生附加费用，因为在链条***中必须存在链条张紧机械装置，以便能够张紧或重新张紧链条。
发明内容
所以，本发明的任务是避免或至少减轻背景技术中所述的缺点。尤其是应当提供一种不用通过齿链连接尤其是主动力总成***的混合动力模块，以便避免使用齿链时的缺点。在此应当为主链条传动提供一个替代方案，其在规定的框架条件下，在曲轴相对于电机的位置、传动比等方面应当到达一个满意的扭矩传递效果。
根据本发明，在此类装置中通过如下方案解决本发明的任务，即：至少两个相互啮合/相互咬合的齿轮为在输出轴与扭矩输入轴之间传递扭矩而与输出轴和扭矩输入轴相连。因此，使用至少一个与第二齿轮咬合的第一齿轮进行扭矩传递。也就是说，主传动不再通过齿链，而是通过齿轮来实现。因此，扭矩传递通过齿轮级实现。
其优点一方面在于，无须提供用于张紧齿链的机械装置，这对于所需的结构空间来说也是有利的。其优点另一方面还在于，通过齿轮进行的扭矩传递所承受的摩擦和离心力负荷相对较小或在给定的负荷下更加坚固。
在从属权利要求中要求了有利的实施方式，下文将会详细说明。
另外有利的是，存在至少三个用于传递扭矩的齿轮，其中，第一齿轮以抗扭转的方式与输出轴相连，第二齿轮以抗扭转的方式与扭矩输入轴相连，并且第三齿轮与第一和第二齿轮啮合。由此可以有利地节省结构空间，尤其是径向结构空间，因为可以使用直径相对小的齿轮。
另外有利的是，齿轮以相互轴向平行的方式布置。由此可以在两个轴向平行的轴、例如电机输出轴与扭矩输入轴之间以相对低的设计成本简单实现扭矩传递。
另外有利的是，齿轮被设计成带有外齿的正齿轮。由此可以通过单级或多级的正齿轮传动装置确保扭矩传递，其中，还可以对所需的传动比进行可变调节。由此就可以针对规定的框架条件简单提供所需的变速器。
特别有利的是，在第一齿轮与第三齿轮和/或在第二齿轮与第三齿轮之间设计了一个斜齿。也就是说，正齿轮传动将会与带有斜齿的齿轮搭配使用。其优点在于，在轮齿啮合时形成的硬碰撞较少并且由此会降低振动，使变速器可以相对安静地运行。由此还可以提高轮齿的耐久性。作为替代方案，还可以使用带有正齿的齿轮。
另外，一种有利实施例的特征在于，在第一齿轮与第三齿轮和/或在第二齿轮与第三齿轮之间设计了一个高齿。也就是说，将会在正齿轮传动装置中使用具有高啮合长度、即齿高系数大于1/优选大于2的齿轮。由此可以大大减少啮合时噪音的形成。
特别有利的是，使用带高齿的斜齿变速器，因为其在声音特性方面特别不明显。
另外有利的是，输出轴与扭矩输入轴之间的传动比可以通过第一齿轮齿数与第二齿轮齿数之间的比例进行调节。在此，布置在第一与第二齿轮之间的齿轮的轮齿数量对于传动比来说是无关紧要的。因此，在选择中间所布置的一个或多个齿轮的尺寸时不用考虑所需的传动比。由此可以优化设计所述一个或多个齿轮。
另外有利的是，第三齿轮的外径大于第一齿轮和/或第二齿轮的外径。因此，应当使用设计得尽可能大的第三齿轮作为中间齿轮，由此可以将中间齿轮的转速保持在低水平上。另外，中间齿轮还承受相对较强的负荷，因为不管是第一齿轮还是第二齿轮都会啮合在中间齿轮中并引入或引出力，所以有利的是，中间齿轮设计有一个优选处于第一齿轮(外部)直径大小0.8倍与1.5倍之间的(外部)直径。
另外有利的是，第一齿轮、第二齿轮和/或第三齿轮通过轴向轴承进行支承。由此可以按有利的方式通过斜齿控制形成的轴向力。
此外有利的是，为了在输出轴与扭矩输入轴之间传递扭矩布置了奇数数量的齿轮。在此，齿轮数量被理解为布置于输出轴固定的第一齿轮与扭矩输入轴固定的第二齿轮之间的、包含第一齿轮和第二齿轮在内的齿轮的数量。由此无需颠倒驱动机的旋转方向。
换句话说，本发明涉及一种带有一个齿轮级的轴向平行的混合动力模块。在此，混合动力模块具有电机，所述电机通过使用齿轮替代链条或皮带与分离离合器、内燃机曲轴或输出轴相连。
因此，力通过三个齿轮从曲轴被传递到电机或从电机被传递到变速器输入轴或曲轴(通过(分离)离合器和减振器)。还可以使用两个或多于三个齿轮，但这取决于存在的结构空间。因此，结构空间限制了齿轮的大小。传动比通过输入与输出轴之间的齿数比进行调节。
公差情况通过齿轮的几何形状控制，或者在安装时通过齿轮副匹配进行最终协调。在此应当通过制造工艺所决定的零件公差波动来避免明显的噪音水平。齿轮的轮齿可以多样化选择。直齿是可用的，斜齿是有利的，带高齿的斜齿是特别有利的。出现的轴向力可以通过齿轮相应的轴承结构进行控制。

驱动机2被设计成电机8。电机8的输出轴4以及第一齿轮5以轴向平行于第二齿轮6和第三齿轮7的方式布置。第二齿轮6以轴向平行于第三齿轮7的方式布置。
