Description

车辆用混合动力装置
技术领域
本发明涉及一种车辆用混合动力装置，更详细而言，涉及一种可以防止异物进入电动机的内部的车辆用混合动力装置。
背景技术
通常，混合动力车辆是指通过有效地组合两种以上不同种类的动力源来驱动车辆，具体地，通过燃烧燃料(汽油等的化石燃料)获得旋转力的发动机和从电池电力获得旋转力的电动机驱动的车辆。
作为混合动力车辆积极地研究采用发电机的同时作为辅助动力源采用电动机来谋求减少废气并提高燃料效率的未来车辆。
这些混合动力车辆通常使用发动机及电动机，在低速时，将低速转矩特性相对良好的电动机用作主动力源，在高速时，将高速转矩特性相对良好的发动机用作主动力源。
因此，混合动力车辆在低速区间使用化石燃料的发动机的运转被停止而使用电动机，因此，在提高燃料效率和减少废气方面具有优异的效果。
混合动力车辆，以仅使用电动机的旋转力的纯电动汽车模式的所谓EV(ElectricVehicle)模式和将发动机的旋转力作为主要动力，并将电动机的旋转力用作辅助动力的所谓HEV(Hybrid Electric Vehicle)模式等的运行模式进行驱动行驶，并通过启动发动机执行从EV模式到HEV模式的模式转换。
例如，轻度混合动力装置，通过组合两个以上的电动机，可以在短时间内体现相当于完全混合动力系统的水平的输出。
这些轻度混合动力装置，根据电动机的位置，通常分为P0、P1、P2、P3、P4，并且在是否实施EV模式、再生制动性能等方面分别显示差异。
另外，在上述混合动力装置中可以形成扭转减震器(Torsion Damper)，所述扭转减震器，在重复压缩动作时，因摩擦而会发生磨损。
此时，由于扭转减震器的磨损而产生的异物可能会飞散到混合动力装置的内部，由于在混合动力装置中的电动机的转子中存在磁体，因此，金属成分的异物会附着在转子上。
因此，会对电动机的性能产生不利影响。

具体实施方式
下面，参照附图详细说明本发明的优选实施例。首先，应注意在对各图中的构成要素标注附图标记时，对相同的构成要素即便是表示在不同的图上也标注相同的附图标记。在说明本发明时，若判断对相关的公知构成或功能的具体说明会使本发明的要旨不明确，则省略对其的详细说明。下面，说明本发明的优选实施例，但是，本发明的技术思想并不局限于此，可由本领域的普通技术人员变形实施为各种形态。
图1是示出根据本发明的一实施例的混合动力装置100的图。
参照图1，混合动力装置100可以设置在壳体H的内部。
混合动力装置100在壳体H的内部可以包括P1电动机10、P2电动机20、扭转减震器30及发动机离合器40。
尽管未图示，在壳体H的一侧可以结合变速器(省略图示)，在另一侧可以结合发动机(省略图示)。
P1电动机10可以由P1定子12和P1转子14而构成，并且，如图1所示，P1定子12可以固定在壳体H。
另外，P2电动机20也可以由P2定子22和P2转子24而构成，并且，如图1所示，P2定子22可以固定在壳体H。
例如，P1转子14可以连接于P1转子轴142，P2转子24可以连接于P2转子轴242。
上述的P1转子轴142可以花键连接于发动机输出轴(省略图示)以通过发动机输出轴接收通过发动机的驱动而产生的旋转动力。
如图1所示，上述的P1电动机10可以布置成比P2电动机20更靠近发动机侧。
另外，扭转减震器30可以设置在P1电动机10和P2电动机20之间，并且，发动机离合器40可以花键连接于P2转子轴242。
例如，扭转减震器还被称为双质量飞轮(Dual mass flywheel)，可以安装在混合动力车辆的发动机和变速器之间，以减弱在动力传递过程中产生的扭转振动。
发动机离合器40可以为连接或切断从发动机传递至变速器的旋转动力的构成。
例如，发动机离合器40可以花键连接于上述的扭转减震器30，如上所述，发动机离合器40与P2转子轴242花键连接而将通过P1转子轴142传递的旋转动力传递到P2转子轴242。
P2转子轴242花键连接于变速器输入轴50，变速器输入轴50可以将通过P2转子轴242传递的旋转动力传递至变速器。
另外，如图1所示，在壳体H的一侧端部(发动机方向)和P1转子轴142的外径部之间设置第一轴承70，并可旋转地支撑P1转子轴142。
另外，在壳体H的另一侧(变速器方向)设置用于支撑变速器输入轴50的支撑部60，并且，在支撑部60的端部和P2转子轴242的外径部之间设置轴承80，并可旋转地支撑P2转子轴242。
图2是图1的A部分放大图。
下面，将参照图1及图2详细说明本发明的扭转减震器30的密封结构。
参照图1及图2，从上述发动机侧看时，P1转子轴142可以形成为围绕扭转减震器30的至少一部分。
此时，可以在P1转子轴142的变速器方向形成开口端。
本发明的实施例中，扭转减震器30在重复压缩动作时，因摩擦而被磨损。
由于扭转减震器30的磨损而产生的异物S可能会飞散到混合动力装置100的壳体H的内部。
此时，P1转子14或P2转子24具有带磁性的物质，飞散的金属成分的异物S附着在P1转子14或P2转子24上，可能会降低电动机的性能。
因此，在本发明的实施例中，通过设置飞散防止部32来防止因扭转减震器30的磨损而产生的异物S飞散到壳体H。
飞散防止部32的一端可以结合于上述的P1转子轴142的变速器方向的端部(开口端)。
例如，飞散防止部32的一端可以通过焊接的方式结合于P1转子轴142的端部，并可以支撑扭转减震器30内的弹簧来保持弹簧的姿势。
另外，飞散防止部32的另一端可以结合于扭转减震器30。
如上所述，扭转减震器30的一侧(发动机方向)可以由P1转子轴142围绕，另一侧(变速器方向)可以由飞散防止部32密封。
由此，由于扭转减震器30的磨损而产生的异物S不会飞散到外部，而残留在由P1转子轴142和飞散防止部32密封的空间中。
另外，由于P1转子14通过从发动机传递的旋转动力而连续旋转，因此，异物S通过P1转子14的离心力而旋转，然后如图2所示，积聚在上述被密封的空间内。
通过上述的密封结构，可以防止由于扭转减震器30的压缩动作而产生的异物S进入P1电动机10或P2电动机20的内部，从而，可以提高P1电动机10或P2电动机20的性能。
图3是示出本发明的其他实施例的图。
如参照图2说明的实施例，在本发明的其他实施例中，扭转减震器3的一侧(发动机方向)可以由P1转子轴142围绕，另一侧(变速器方向)可以由飞散防止部32密封。
参照图3，P1转子轴142还包括朝P1转子14方向凹陷的凹槽1422。
如上所述，异物S可以通过P1转子14的离心力而旋转并积聚在被密封的空间中，在本发明的其他实施例中，如图3所示，通过形成凹槽1422可以更加提高异物S的捕集量。
以上说明是例示说明本发明的技术思想而已，本发明所属技术领域的普通技术人员在不改变本发明的本质特性的范围内可以进行各种修改、变更及取代。因此，本发明中公开的实施例及附图是用于说明本发明的技术思想，而不限制本发明的技术思想，本发明的技术思想范围并不局限于这些实施例及附图。本发明的保护范围应由权利要求范围而解释，应解释为与其同等范围内的所有技术思想均包含于本发明的权利范围中。
