Description

用于混合动力车的动力传输装置
技术领域
本发明涉及一种用于混合动力车的动力传输装置。更特别地，本发明涉及一种能够减小发动机振动、促进发动机离合器控制并提供适合于大规模生产的组装配置(package layout)的用于混合动力车的动力传输装置。
背景技术
通常，用于混合动力车的动力传输装置具有这样的配置：自动变速器、电机、发动机和集成启动发电机(ISG)被排成一行。
在以协作的方式使用发动机和电机的混合动力车中，在低RPM下具有高效率的电机被用于初始加速。当车辆达到预定速度时，发电机(即，ISG)启动发动机，并且同时使用发动机和电机的输出。
此时，为了整体地使用发动机的输出和电机的输出，车辆具有这样的结构：每个输出均被连接至自动变速器的行星齿轮的一个组件。
即，发动机被连接至行星齿轮的托架，ISG被连接至行星齿轮的中心齿轮，并且电机被连接至环形齿轮。
因此，发动机的转动动力在自动变速器的行星齿轮中被调节至适当速度，然后被传递至驱动轴，并且最终通过推进轴传递至驱动轮。
同时，连接至自动变速器中的行星齿轮的中心齿轮的ISG从发动机接收旋转动力并在减速过程中产生电力。ISG所产生的电力通过逆变器(未绘出)被充电至充电器，然后逆变器向电机供应电力，以在车辆启动或加速时转动驱动轴。
由于用于混合动力车的动力传输装置具有自动变速器、电机、转矩变换器、发动机和ISG被排成一行的结构，所以发动机室的总长度增加，并且因此在各个部件的配置和安装方面是不利的。此外，很难将这样的动力传输装置一般地应用于多种不同的平台。因此，旨在开发有利于大规模生产并具有最优配置的动力传输装置的广泛研究在不断进行。
美国专利第6,176,808号公开了一种用于混合动力车的动力传输的配置，其中电机通过扭振减震器连接至变速器的输入轴。然而，这样的配置的缺点在于发动机离合器、扭振减震器等的位置复杂。
此外，美国专利第6,474,428号公开了一种用于混合动力车的动力传输的配置，其中电机和发动机离合器并不布置在同一空间中，而是由盖体隔开。因此，其缺点在于电机没有浸在油中，并且因此降低了冷却效率。
在该背景部分中公开的信息只是用来提高对发明背景的理解，并且不应该作为该信息形成了本领域的专业技术人员已知的现有技术的确认或任何形式的暗示。
发明内容
本发明是为了致力于解决上述问题而做出的，并且本发明的一个目的是提供一种用于混合动力车的动力传输装置，其中发动机离合器被布置在电机和自动变速器之间，发动机离合器的一部分被布置成与电机的内侧重叠，电机盖壳体安装在电机和扭振减震器之间以防止传动油流至扭振减震器，并且扭振减震器的一部分被布置成与曲轴重叠。因此，通过发动机离合器、电机、电机壳体和扭振减震器被布置在同一空间中的该最优配置，可提供减小发动机振动的效果、促进发动机离合器控制并使大规模生产能够得到实现。
在一个方面中，本发明提供了一种用于混合动力车的动力传输装置，其中具有输入轴的自动变速器、电机、扭振减震器和具有输出轴的发动机被排成一行，所述输出轴被连接至所述发动机的曲轴，所述动力传输装置包括：电机支撑轴，其外端由电机转子支撑，内端朝向发动机的输出轴和自动变速器的输入轴之间的边界延伸；电机壳体，其被布置成围绕电机转子的外周和左侧表面；发动机离合器，其布置在电机壳体的左侧端和电机支撑轴的内端的左侧表面之间，以在发动机的输出轴和自动变速器的输入轴之间进行动力传输；电机盖壳体，其被布置成覆盖电机转子的右侧表面和电机支撑轴的内端的右侧表面，并且所述电机盖壳体在其右侧表面上包括凹部；以及扭振减震器，其被安置在电机盖壳体的凹部中以与电机转子隔开。
在优选实施例中，用于支撑电机支撑轴的转动的支撑轴承被安装在电机支撑轴的内端和电机盖壳体的内端之间。
在另一优选实施例中，电机位置传感器被安装在电机盖壳体的内端的左侧表面上，同时与电机支撑轴的右侧表面相邻。
在另一优选实施例中，电机支撑轴的内端一体地形成在与电机转子接合的电机支撑轴的外端的中央位置。
在另一优选实施例中，扭振减震器在其外周上包括用于衰减发动机的扭转振动的扭簧。
在另一优选实施例中，扭振减震器的一部分被布置成与曲轴的顶部重叠。
应该理解的是，本文中使用的术语“车辆”、“车辆的”或其它类似术语，总体来说包括机动车辆，诸如包括运动型多功能车(SUV)、公共汽车、卡车、各种商用车辆的载客汽车，包括各种小船和轮船的船舶，航空器，等等。本发明将特别有用于广泛种类的机动车辆。

具体实施方式
现在将详细参考本发明的优选实施例，其实例在下文中所附的图中示出，其中相同的附图标记始终指代相同的元件。下面将通过参考这些附图来描述实施例以便说明本发明。
图1是示出根据本发明的用于混合动力车的动力传输装置的动力传输的示意图，并且图2是示出根据本发明的用于混合动力车的动力传输装置的结构的示意横剖视图。
根据本发明的优选实施例的用于混合动力车的动力传输装置具有这样的配置：具有输入轴18的自动变速器16、电机26、扭振减震器38、连接至发动机20的曲轴40的发动机输出轴14等被直接连接在同一轴上。
本发明旨在最优地布置用于混合动力车的动力传输装置的各个部件，以便提供减小发动机振动的效果、促进发动机离合器控制并提供使大规模生产能够得到实现的组装型配置。
首先，将在下文中描述直接连接在发动机20和自动变速器16之间的电机组件的配置。
电机组件包括电机转子10和适于支撑该电机转子10的电机支撑轴12。电机支撑轴12的外端与电机转子10接合，并且电机支撑轴12的内端朝向连接至发动机20的发动机输出轴14和自动变速器16的输入轴18之间的边界延伸。
这里，电机支撑轴12的内端一体地形成在电机支撑轴12的外端的中央位置，以便具有均匀分布的支撑强度并避免不希望有的旋转动量。另外，如图2所示，电机支撑轴12的内端具有“U”形的剖面。
同时，电机组件包括电机壳体22，其被布置成以预定的距离围绕电机转子10的外周和左侧表面以及电机支撑轴12的左侧表面。
特别地，设置了用于在发动机输出轴14和自动变速器16的输入轴18之间进行动力传输的发动机离合器24。发动机离合器被布置在电机壳体22的左侧端和电机支撑轴12的内端的左侧表面之间的空间中。
因此，电机转子10、发动机离合器24和支撑电机转子10的电机支撑轴12被布置在同一空间中(即，电机壳体22内部)。
因此，发动机离合器24被布置在电机26和自动变速器16之间，并且发动机离合器24的一部分被布置成与电机26的内侧(即电机转子10的内周)重叠，由此改善了空间利用。
同时，电机组件包括电机盖壳体28，其被布置成以预定距离覆盖电机转子10的右侧表面和电机支撑轴12的内端的右侧表面。
在这种情况下，将用于支撑电机支撑轴12的转动的支撑轴承30安装在电机支撑轴12的内端和电机盖壳体28的内端之间。
此外，将电机位置传感器32安装在电机盖壳体28的内端的左侧表面上，同时电机位置传感器32与电机支撑轴12的右侧表面相邻。电机位置传感器32检测电机转子10的位置和转速。
同时，将具有凹进空间的凹部36形成在电机盖壳体28的右侧表面上，并且将扭振减震器38布置在电机盖壳体28的凹部36中。
因此，电机转子10和扭振减震器38通过电机盖壳体28彼此隔开。电机盖壳体28防止传动油流至扭振减震器38，继而减少油损失量并防止可能由传动油引起的扭振减震器的驱动损耗。
在这种情况下，扭振减震器38包括用于衰减发动机的扭转振动的扭簧42。
也就是说，为了有效地衰减发动机的扭转振动，将扭簧42安置在与电机转子10对齐的扭振减震器38的外周上，并且为了保证空间，将扭振减震器38的一部分布置成与曲轴40的顶部重叠。如上所述，将发动机离合器布置在电机和自动变速器之间，将发动机离合器的一部分布置成与电机的内侧重叠，并且将扭振减震器的一部分布置成与曲轴重叠。因此，通过发动机离合器、电机、电机壳体和扭振减震器被布置在同一空间内的最优配置，可提供使大规模生产能够得到实现的组装型配置。
因此，本发明提供了以下的有利效果。
通过发动机离合器被布置在电机和自动变速器之间，发动机离合器的一部分被布置成与电机的内侧重叠，并且电机盖壳体被安装在电机和扭振减震器之间以防止传动油流至扭振减震器的配置，可同时增强对发动机离合器和电机的油冷却效果。
通过发动机离合器、电机、电机壳体和扭振减震器被布置在同一空间中的最优配置，本发明提供了减小发动机振动的效果，促进了发动机离合器控制，并使大规模生产能够得到实现。
已经参考本发明的优选实施例对本发明进行了详细描述。然而，本领域技术人员应该理解的是，可对这些实施例做出改变而不脱离本发明的原理和精神，本发明的范围由所附权利要求及其等效物限定。
