Description

线圈多冷却路径型驱动电机以及具有该电机的环保型车辆
技术领域
本发明涉及驱动电机冷却，更具体涉及一种使用驱动电机的环保型车辆，其中利用形成在多个位置处的冷却路径以立体方式对线圈进行冷却。
背景技术
通常情况下，利用环保型车辆的驱动电机来实现以电动机驱动的电动车辆(EV)的行驶模式，以及以电动机和发动机组合驱动的混合动力电动车辆(HEV)的行驶模式。这种环保型车辆是混合动力车辆，并且包括混合动力电动车辆(HEV)、插电式混合动力电动车辆(PHEV)、电动车辆(EV)、燃料电池电动车辆(FCEV)、轻度混合动力电动车辆(MHEV)等。
驱动电机包括卷绕线圈的定子，且该定子联接至电机壳体中；以及转子，其以预定间隙设置在定子中。驱动电机包括冷却结构，其对由施加于线圈的电流以及因反电动势引起的涡流而产生的热量进行冷却。特别地，冷却结构根据利用变速器壳体安装驱动电机的环保型车辆的特性使用油冷却方式，并且油冷却方式允许将自动变速器油用作冷却油(以下称为油)，以吸收并冷却由电机壳体中的线圈产生的热量。
例如，油冷却方式使用从发动机离合器连接至转子套筒和绕线轴的散射冷却路径，并且转子套筒内的油通过转子的旋转经散射冷却路径散射到转子套筒的外部，以利用通过绕线轴散射的油对卷绕在绕线轴上的线圈进行冷却。因此，即使相当长时间地驱动驱动电机时，也可以防止驱动电机因过热而损坏，从而保持驱动电机的性能。然而，由于油通过散射冷却路径的油散射对冷却线圈没有太大影响，因此油冷却方式具有局限性。
特别地，由于油冷却方式中的散射冷却路径形成在发动机离合器的联接方向上的一个位置处，并且具体地油仅散射在转子套筒和绕线轴中的线圈前端，因此由散射的油对线圈的冷却效果不会影响线圈的后方。将卷绕在定子上的线圈在驱动电机的宽度上沿发动机离合器的联接方向定向的方向定义为线圈的前方，而将与上述方向相反的方向定义为线圈的后方。因此，由于较少量的油被散射到线圈的后方而不是线圈的前方，因此油冷却方式会导致冷却效果存在差异，而这会产生不均匀的电机冷却性能。因此，需要很大努力来控制环保型车辆中的驱动电机的温度。
发明内容
本发明的一个示例性实施例旨在提供一种线圈多冷却路径型驱动电机，其除了线圈冷却路径和发动机离合器冷却路径之外还包括旋转变压器冷却路径，以在转子套筒的整个宽度上将油散射到线圈的前方和后方以使线圈冷却性能最大，特别地，通过散射驱动转子所需的油与流入发动机离合器和旋转变压器的油而显著提高了直接冷却定子空间的效果，以及具有该电机的环保型车辆。
通过下面的描述参照本发明的示例性实施例，本发明的其它目的和优点可以被更好地理解并变得明显。而且，对于本发明所属领域的技术人员显而易见的是，本发明的目的和优点可以通过所主张的装置及其组合来实现。
根据本发明的示例性实施例，一种驱动电机，包括：线圈多冷却路径，在转子的离心力作用下收集的油，通过线圈多冷却路径，从转子套筒的内部空间流入发动机离合器以便向线圈的前后方向散射，同时从转子套筒的外部空间流入旋转变压器以便向线圈的后方散射。流入旋转变压器的油可以与流入发动机离合器中的向线圈的后方散射的油相混合。

参照图1，驱动电机1可以包括电机本体2-1、线圈多冷却路径10以及冷却通道50。特别地，电机本体2-1中可以包括转子3和定子7，并且可以通过其中形成有冷却通道50的电机壳体2-2联接至发动机，以定位发动机离合器，从而切断发动机的动力并将其供应到转子3中。例如，转子3可以包括：转子套筒4，该转子套筒4由具有轴向孔口和开放内部空间的圆形体形成；具有圆环状的保持器5；以及具有圆环状的转子板6。特别地，保持器5可以与转子套筒4联接，并且转子板6可以与保持器5联接。定子7可以包括绕线轴8和卷绕在绕线轴8上的线圈9。绕线轴8可以围绕转子3，并且可将电流供应至线圈9。
因此，转子3可以通过供应至定子7的电流而旋转，并且输出轴可以随着转子3的旋转而旋转，因此，驱动电机1可被配置成输出转矩。特别是，线圈多冷却路径10形成油散射路径，通过该油散射路径，在转子3的旋转的离心力作用下，将吸入到电机本体2-1的油在线圈9的前后方向上集中地散射。例如，线圈多冷却路径10可包括线圈冷却路径20，其从转子套筒4的内部空间向线圈9的前方引导，以使油通过线圈冷却路径20向线圈9的前方散射。
线圈多冷却路径10可以包括从转子套筒4的内部空间沿线圈9的后方引导的发动机离合器冷却路径30，以及从与位于驱动电机内部的旋转变压器连接的转子套筒4的外部空间沿线圈9的后方引导的旋转变压器冷却路径40，从而使油通过发动机离合器冷却路径30和旋转变压器冷却路径40沿线圈9的后方散射。特别地，当转子3和定子7被组装到电机本体2-1上时，将线圈9的前方定义成朝向驱动电机1外侧的方向，并且将线圈9的后方定义成朝向驱动电机1内侧的方向。
因此，线圈多冷却路径10可以分成在转子3的转子套筒4中以间隔的方式独立形成的线圈冷却路径20和发动机离合器冷却路径30，以及形成在转子3的转子套筒4中的旋转变压器冷却路径40，并且与发动机离合器冷却路径30垂直地间隔开。因此，线圈9的露出前部可以通过散射经由线圈冷却路径20流入发动机离合器的油而得以冷却。此外，线圈9的露出后部可以通过散射经由发动机离合器冷却路径30流入发动机离合器的油以及通过旋转变压器冷却路径40流入旋转变压器的油而得以冷却。因此，由于线圈9被流经线圈多冷却路径10的油直接冷却，因此驱动电机1可以具有改善的冷却效率，由此有助于提高EV的行驶性能。
特别地，冷却通道50可以形成在电机壳体2-2中，用于冷却剂的流入和流出以冷却电机本体2-1的内部。在冷却通道50的布置中，冷却通道50可以以Z字形围绕电机本体2-1，并且可以与冷却剂循环系统连接。冷却剂循环系统可以利用诸如HEV之类的环保型车辆中的发动机冷却系统来构成，但也可以在诸如EV之类的环保型车辆中独立地构成。
图2示出线圈冷却路径20和发动机离合器冷却路径30的详细结构。特别地，线圈冷却路径20可以具有前绕线轴散射孔21和前线圈散射槽23(参见图3)。前绕线轴散射孔21可以形成在用于限定转子套筒4的内部空间的圆形体的径向上，位于电机外侧的位置处，以在转子3的旋转产生的离心力作用下，将填充在转子套筒4的内部空间中的油朝向转子套筒4的外部空间(例如，布置线圈的空间)散射。前线圈散射槽23可以形成在绕线管8中，位于电机外侧的位置处，以将从前绕线轴散射孔21散射的油向线圈9的前方散射。
特别地，发动机离合器冷却路径30可以包括后绕线轴散射孔31和后线圈散射槽33。后绕线轴散射孔31可以沿转子套筒4的圆形体的轴向形成在电动机内部的位置处，以在其旋转产生的离心力作用下，将填充在转子套筒4的内部空间中的油散射到转子套筒4的外侧。因此，从后绕线轴散射孔31散射的油，可以通过转子套筒4的套筒间隙4-1、保持器5的保持器间隙5-1以及转子板6，朝向绕线轴8散射。后线圈散射槽33可以形成在绕线轴8中电动机内部的位置处，以便将从后绕线轴散射孔31散射的油向线圈9的后方散射。
参照图3，绕线轴8具有分别从绕线轴本体的两侧以90度弯曲的前凸缘8-1和后凸缘8-2，并且在前后两侧卡住卷绕在绕线轴本体上的线圈。特别地，前凸缘8-1和后凸缘8-2可被修改为各种形状，使得被散射的油可进一步被引导并分散到线圈9。
例如，可以通过将前凸缘8-1的一部分切割成预定形状，从而在前凸缘8-1中形成前线圈散射槽23，并且可以通过将后凸缘8-2的一部分切割成预定形状，从而在后凸缘8-2中形成后绕线轴散射孔31。因此，前线圈散射槽23使得从线圈冷却路径20的前绕线轴散射孔21散射的油，朝向线圈9的前方被引导。此外，后绕线轴散射孔31使得从发动机离合器冷却路径30的后绕线轴散射孔31散射的油朝向线圈9的后方被引导。
图4示出与发动机离合器冷却路径30连接的旋转变压器冷却路径40的详细结构。特别地，旋转变压器冷却路径40可以与发动机离合器冷却路径30的后绕线轴散射孔31连接。因此，后绕线轴散射孔31可以包括入口通道31-1、连接通道31-2以及出口通道31-3。入口通道31-1可以与转子套筒4的内部空间连通，以作为油流入的入口。连接通道31-2可形成被引入到入口通道31-1中的油流至出口通道31-3的油流动路径。出口通道31-3可以形成在转子套筒4中，使得转子套筒4的内部空间与其外部空间连通。特别地，出口通道31-3可以位于旋转变压器冷却路径40的油散射路径上，使得经由入口通道31-1和连接通道31-2流入发动机离合器的油、从旋转变压器冷却路径40排出以流入发动机离合器的油、以及流入旋转变压器的油被收集，并向线圈9的后方散射。
例如，连接通道31-2可以是沿转子套筒4的长度方向形成的直线通道。入口通道31-1可以是直线通道，其从连接通道31-2的第一端以直角垂直地引导，以便与转子套筒4的内部空间连通，从而使流向发动机离合器的油流入。出口通道31-3可以是从连接通道31-2的第二端以直角形成在转子套筒4中的直线通道。因此，入口通道31-1和出口通道31-3可以位于连接通道31-2的左侧和右侧。特别地，旋转变压器冷却路径40包括旋转变压器通道41和集油突起43。
例如，旋转变压器通道41可以以一定倾角形成在旋转变压器毂(boss)37中，该旋转变压器毂37与形成于转子套筒4的圆形体上的轴套(shaft boss)35以同心的形式突出。该倾角是从旋转变压器通道41通向集油突起43的假想线形成的角度。集油突起43可以从转子套筒4突出以围绕转子套筒4的出口通道31-3的部分中的出口通道31-3的一个表面。特别地，出口通道31-3的一个表面指的是散射在旋转变压器通道41上的油离开转子套筒4的位置。
图5和图6示出应用驱动电机1的环保型车辆100的示例。参照图5，环保型车辆100包括与发动机离合器200连接的驱动电机1和变速器100-1。特别地，驱动电机1被配置成使得发动机离合器200布置在转子3的内部空间中，输出轴与转子3的轴套35联接，并且旋转变压器朝向转子3的旋转变压器毂37布置。变速器100-1可被配置成通过从驱动电机1传递的动力来改变车辆速度。
具体而言，由于驱动电机1与参照图1至图4描述的线圈多冷却路径型驱动电机1相同，因此驱动电机1包括与转子3连接的线圈多冷却路径10。因此，线圈多冷却路径10使流入发动机离合器的油可以通过线圈冷却路径20向线圈9的前方散射，以对线圈9的前部进行冷却，同时使流入发动机离合器和旋转变压器的油可以从旋转变压器冷却路径40向线圈9的后方，散射到发动机离合器冷却路径30，以对线圈9的后部进行冷却。
参照图6，驱动电机1可以填充从变速器100-1供应到发动机离合器200的自动变速器油(ATF(auto transmission fluid))300。因此，驱动电机1可被配置成通过从线圈9供应的电流，随着转子3的旋转，从输出轴输出转矩。ATF300是流向发动机离合器的油，并且在基于构成转子3的转子套筒4的旋转产生的离心力作用下，将其供应至线圈冷却路径20和发动机离合器冷却路径30。同时，ATF300是流入发动机离合器和旋转变压器的油，并且可被供应至旋转变压器冷却路径40。
流入发动机离合器的油被引入到前绕线轴散射孔21和发动机离合器冷却路径30的后绕线轴散射孔31的入口通道31-1中，流入发动机离合器和旋转变压器的油，从旋转变压器冷却路径40的旋转变压器通道41经散射流入后绕线轴散射孔31的出口通道31-3，与从发动机离合器冷却路径30的入口通道31-1经由连接通道31-2到达出口通道31-3的流入发动机离合器的油进行混合。特别地，旋转变压器冷却路径40的集油突起43，可防止从旋转变压器通道41散射的油分散在出口通道31-3的附近。
此外，从线圈冷却路径20的前绕线轴散射孔21散射的油，可以通过绕线轴8的前线圈散射槽23散射，以润湿线圈9的前侧。同时，从发动机离合器冷却路径30的出口通道31-3散射的油可以通过绕线轴8的后线圈散射槽33散射以润湿线圈9的后侧。因此，由于线圈9的前侧由流入发动机离合器的油润湿，线圈9的后侧由与流入旋转变压器的油相混合的流入发动机离合器的油润湿，因此可以通过在线圈9上散射足够量的油，来提高线圈的整体冷却效率。此外，从旋转变压器冷却路径40和发动机离合器冷却路径30散射的油可以直接冷却定子7的空间。因此，由于驱动电机1具有有效的冷却性能，因此可以将驱动电机1应用于环保型车辆，以最小的努力控制驱动电机的温度。
如上所述，应用于环保型车辆100的驱动电机1，可以包括具有线圈冷却路径20、发动机离合器冷却路径30以及旋转变压器冷却路径40的线圈多冷却路径10。由于在转子套筒4的离心力作用下收集的油，可以流入发动机离合器和旋转变压器，以向线圈9的前后方向散射，并且通过线圈冷却路径20、发动机离合器冷却路径30和旋转变压器冷却路径40的互连来润湿线圈9的前部和后部，因此可以使线圈9的整体冷却性能最大。特别地，由于流入发动机离合器的油与流入旋转变压器的油混合以散射到线圈9上，因此可以在油散射过程中利用足够量的油对定子7的空间直接进行冷却。
本发明的驱动电机由于在三个油散射位置处具有线圈多冷却路径结构，因而具有以下优点和效果：首先，由于流入发动机离合器和旋转变压器的全部油以立体方式散射在线圈的前侧和后侧，因此可以通过足够量的油使线圈冷却效果达到最佳；其次，由于当油被散射在线圈的前侧和后部侧，油直接被输送给定子，因此可从总体上显著提高电机冷却性能；第三，由于诸如线圈冷却路径、发动机离合器冷却路径和旋转变压器冷却路径的三个立体油散射结构与转子连接，因此可以通过转子的旋转力而有效地散射油；第四，由于滑动槽和集油突起与油散射结构连接，因此可以有效地防止散射油散开并增加被输送到线圈的油的流速；第五，可以通过最佳地形成卷绕线圈的绕线轴，形成更有效的冷却结构；第六，由于套筒与油散射结构相连，因此在将油输送到定子的任何位置处都可以应用油散射结构；第七，可以通过旋转变压器冷却路径利用在旋转变压器中残留的油，以使散射效果最佳；第八，可以通过应用于转子套筒和绕线轴的油散射结构，显著提高电机冷却性能，而不需要单独的额外元件和成本。
此外，在本发明的环保型车辆中，由于驱动电机在三个油散射位置处具有线圈多冷却路径结构，因此具有改善的冷却性能。因此，可以减少用来控制驱动电机的温度，特别是通过进一步提高线圈冷却性能来提高电机的耐久性和适销性所需的努力。
尽管已经参照示例性实施例对本发明进行描述，然而对于本领域技术人员来说显而易见的是，在不脱离如所附权利要求限定的本发明的精神和范围的情况下，还可以对本发明进行各种改变和修改。
