具体实施方式
在下文中,将描述根据本发明的车辆驱动系统的第一实施例。本发明不限于第一实施例。在第一实施例中,将作为示例描述根据本发明的车辆驱动系统应用于设置有内燃机和旋转电机两者作为车辆的驱动动力源的车辆驱动系统的情况。在以下描述中,除非另外提及,否则与旋转电机的旋转轴线平行的方向被称为“轴向方向”。此外,相应的方向通过使用附图中的箭头适当地指示,同时将安装有车辆驱动系统的车辆的前后方向上的前侧称为“FR”,将车辆的左右方向上的右侧称为“RH”,并且将车辆的高度方向上的上侧称为“UPPER”。
图1是根据第一实施例的车辆驱动系统的骨架图。根据第一实施例的车辆驱动系统1包括内燃机EG和被容纳在变速驱动桥外壳2中的第一旋转电机MG1和第二旋转电机MG2。变速驱动桥外壳2是本发明的“外壳”的示例。第一旋转电机MG1和第二旋转电机MG2是用作车辆的驱动动力源的两个旋转电机。
首先,将描述车辆驱动系统1的整体构造。如图1中所示,车辆驱动系统1包括被驱动地联接到内燃机EG的输入轴I、第一旋转电机MG1、第二旋转电机MG2、动力分配装置PT和输出齿轮G、中间轴齿轮机构CM和差动齿轮DF。这些部件中的每一个部件都被容纳在被固定到车身的变速驱动桥外壳2中。
输入轴I被驱动地联接到内燃机EG。这里,内燃机EG是由发动机的内部的燃料的燃烧驱动以输出原动力的设备,例如,可以使用各种公知的发动机之一,例如汽油发动机和柴油发动机。在第一实施例中,输入轴I被驱动地联接到输出旋转轴,例如内燃机EG的曲轴,以便与输出旋转轴一体地旋转。输入轴I可以适当地构造成经由诸如阻尼器和离合器的另一构件被驱动地联接到内燃机的输出旋转轴。
第一旋转电机MG1包括被固定到变速驱动桥外壳2的第一定子St1,以及在径向方向上可旋转地支撑在第一定子St1的内侧的第一转子Ro1。第一旋转电机MG1的第一转子Ro1被驱动地联接到动力分配装置PT的太阳齿轮S,以便与太阳齿轮S一体地旋转。此外,第二旋转电机MG2包括被固定到变速驱动桥外壳2的第二定子St2和在径向方向上被可旋转地支撑在第二定子St2的内侧的第二转子Ro2。第二旋转电机MG2的第二转子Ro2通过中间轴齿轮机构CM被驱动地联接到差动齿轮DF。第一旋转电机MG1和第二旋转电机MG2各自被电连接到作为蓄电装置的电池(未示出)。电池是蓄电装置的示例。可以使用诸如电容器的另一蓄电装置,或者可以组合使用多种类型的蓄电装置。此外,电池可以被构造成可由外部电源充电,例如家用电源。
第一旋转电机MG1和第二旋转电机MG2各自具有作为通过接收电力供给来产生原动力的马达(电动马达)的功能以及作为通过接收原动力供给来产生电力的发电机(电力发生器)的功能。这里,当第一旋转电机MG1和第二旋转电机MG2用作发电机时,它们通过内燃机EG的扭矩或车辆的惯性力产生电力给电池充电,或者供给电力来驱动用作马达的其他旋转电机。另一方面,当第一旋转电机MG1和第二旋转电机MG2用作马达时,它们通过接收用来对电池充电的电力供给或由用作发电机的其他旋转电机产生的电力供给来执行动力运行。
如图1中所示,动力分配装置PT由与输入轴I同轴布置的单小齿轮类型的行星齿轮机构构造。也就是说,动力分配装置PT包括支撑多个小齿轮的载架CA以及分别与小齿轮啮合的太阳齿轮S和齿圈R作为旋转元件。这三个旋转元件被布置成使得太阳齿轮S、载架CA和齿圈R按照它们的旋转速度的顺序定位。太阳齿轮S被驱动地联接到第一旋转电机MG1的第一转子Ro1,以便与第一转子Ro1一体地旋转。载架CA被驱动地联接到输入轴I,以便与输入轴I一体地旋转。齿圈R被驱动地联接到输出齿轮G,以便与输出齿轮G一体地旋转。输出齿轮G在轴向方向上在动力分配装置PT和内燃机EG之间设置在输入轴I的径向外侧。
动力分配装置PT具有将通过输入轴I输入的内燃机EG的驱动力(这里,“驱动力”与“扭矩”同义地使用)分配到第一旋转电机MG1和输出齿轮G的功能。此外,第一旋转电机MG1的转速和扭矩在输入轴I(内燃机EG)的扭矩被输入到动力分配装置PT的载架CA中的状态下被控制,并且由此输入轴I的转速可以被连续改变并被传输到输出齿轮G。
输出齿轮G经由中间轴齿轮机构CM被驱动地联接到差动齿轮DF。第二旋转电机MG2的第二转子Ro2也经由中间轴齿轮机构CM被驱动地联接到差动齿轮DF。因此,在第一实施例中,第二旋转电机MG2的第二转子Ro2经由中间轴齿轮机构CM驱动地联接到输出齿轮G。然后,在第一实施例中,由动力分配装置PT分配到输出齿轮G的输入轴I(内燃机EG)的扭矩的一部分和第二旋转电机MG2的输出扭矩被合成并且传输到差动齿轮DF。差动齿轮DF经由轮轴O被驱动地联接到车轮W,并且将输入差动齿轮DF的旋转和扭矩分配并传输到左右两个车轮W。
图2是从车辆的前侧观察的变速驱动桥外壳2的外部视图。图3是沿图2的线III-III截取的变速驱动桥外壳的剖视图。如上所述,变速驱动桥100被构造成使得容纳第一旋转电机MG1和第二旋转电机MG2的变速驱动桥外壳2、被联接到变速驱动桥外壳2的一侧(内燃机EG被布置在该侧上)的变速驱动桥壳体3和被联接到变速驱动桥外壳2的另一侧(与布置内燃机EG的一侧的相反的一侧)的盖(未示出)一体地组装。
在第一实施例的变速驱动桥100中,输入轴I、动力分配装置PT、第一旋转电机MG1和输出齿轮G都被布置在第一轴线A1上。第二旋转电机MG2被布置在第二轴线A2上。中间轴齿轮机构CM被布置在第三轴线A3上。差动齿轮DF被布置在第四轴线A4上。这些部件相互平行地布置在不同位置。在第一实施例中,第二旋转电机MG2被布置在第一旋转电机MG1的斜上方。此外,如图3中所示,第一轴线A1、第二轴线A2和第四轴线A4被布置成使得连接这三个轴线的相应线段形成锐角三角形。布置在第一轴线A1上的第一旋转电机MG1、布置在第二轴线A2上的第二旋转电机MG2和布置在第四轴线A4上的差动齿轮DF被布置成彼此在径向方向上相邻。布置中间轴齿轮机构CM的第三轴线A3位于通过连接第一轴线A1、第二轴线A2和第四轴线A4的三个轴线限定的锐角三角形的内侧。
变速驱动桥外壳2包括至少径向地覆盖第一旋转电机MG1和第二旋转电机MG2的外周的外周壁部2a。外周壁部2a形成为不规则的筒状,其沿着并且覆盖径向彼此相邻的第一旋转电机MG1和第二旋转电机MG2以及差动齿轮DF的相应的外周表面延伸。变速驱动桥外壳2通过使用诸如铝的金属材料形成。
如图2和图3中所示,PCU安装部20被设置在变速驱动桥外壳2的顶部和外周壁部2a的外周表面上,在PCU安装部20中安装有未示出的电力控制单元(PCU),作为用于控制供给到第一旋转电机MG1和第二旋转电机MG2的电力的电力控制装置。PCU安装部20具有盒状形状(其具有开口顶表面),并且包括:在车辆前后方向上彼此面对的前壁部分20a和后壁部分20b;在车辆左右方向上彼此面对的右壁部分20d和左壁部分20e;形成PCU安装部20的底部的底壁部分20c;以及允许顶表面打开的开口部分20f。后壁部分20b和底壁部分20c被包括在变速驱动桥外壳2的外周壁部2a中。后壁部分20b在车辆前后方向上相对于底壁部分20c向后倾斜,并且由后壁部分20b和底壁部分20c限定的角度在与变速驱动桥外壳2的轴向方向垂直的横截面中是钝角。此外,由后壁部分20b和底壁部分20c限定的拐角部分位于被形成在第一旋转电机MG1和第二旋转电机MG2之间的凹进空间中。
图4是PCU 10的分解图。PCU 10包括控制板11、电力堆叠体12、PCU侧汇流条13、电抗器14、电容器15、水套16、直流-直流变换器17和未示出的PCU盖18(参见图5)等。
电力堆叠体12通过堆叠多个电力卡来构造,每个电力卡通过模块化控制第一旋转电机MG1和第二旋转电机MG2的绝缘栅双极晶体管(IGBT)、二极管等来形成,冷却器的冷却板介于电力卡之间,并且电力堆叠体12由控制板11控制。作为第一连接端子的PCU侧汇流条13被电连接到作为第二连接端子的变速驱动桥侧汇流条。电抗器14用于提高电池电压。电容器15平滑化来自直流-直流变换器(下文中“直流-直流变换器”被称为“直流-直流变换器”)17的直流电压,并将平滑化的直流电压供给至电力堆叠体12,或者平滑化来自电力堆叠体12的直流电压,并将平滑化的直流电压供给至直流-直流变换器17等。水套16通过流经设置在内部的水通道的冷却剂冷却电抗器14、直流-直流变换器17等,并且还用作保持电力堆叠体12、电抗器14、电容器15等的保持构件。直流-直流变换器17降低来自电池或PCU 10的直流电压,将降低的直流电压供给至诸如车辆照明的辅助设备,并且用降低的直流电压为辅助设备的电池充电。PCU盖18具有盒状形状(其具有开口下表面),并且附接到PCU安装部20的顶部,以便封闭开口部分20f。此外,PCU盖18的深度被设置为足够深以包围控制板11的周边。
在第一实施例中,PCU 10在高度方向上具有多层结构,并且被构造为PCU组件10A,该PCU组件10A通过在PCU 10的高度方向上从下侧(变速驱动桥100侧)依次堆叠和集成直流-直流变换器17、水套16、电抗器14和电容器15、电力堆叠体12和控制板11而形成。在PCU组件10A中,电力堆叠体12、电抗器14和电容器15以及直流-直流变换器17被紧固到水套16。
在PCU组件10A中,电抗器14和电容器15、水套16和直流-直流变换器17顺序堆叠在电力堆叠体12的下方。因此,例如,与电抗器14和电容器15以及直流-直流变换器17在水套16的下方以平坦方式并排布置的情况相比,PCU组件10A被布置成更向下突出(朝向变速驱动桥100侧)。
当PCU 10被安装在PCU安装部20中时,PCU 10的下部的一部分,例如PCU组件10A的电抗器14和直流-直流变换器17的相应部分被布置在被形成于第一旋转电机MG1和第二旋转电机MG2之间的凹进空间中。
具体而言,如图5中所示,当PCU 10安装到PCU安装部20中时,PCU 10被布置在当PCU盖18被附接到PCU安装部20的顶部时由PCU安装部20和PCU盖18的内部空间形成的安装区域F2内。此外,PCU 10的下部的一部分位于安装区域F2中的空间内,该空间由线D、第一旋转电机MG1和第二旋转电机MG2包围,其中线D连接第二旋转电机MG2在垂直方向上的中心线和变速驱动桥外壳2之间的交点B以及与第一旋转电机MG1在水平方向上的中心线相交的第一旋转电机MG1的切线和变速驱动桥壳2之间的交点C。换句话说,在与变速驱动桥外壳2的轴向方向垂直的横截面中,PCU 10的下部的一部分位于由PCU安装部20的后壁部分20b、底壁部分20c和线D包围的区域F1内。
因此,在将PCU 10安装到变速驱动桥外壳2上时,通过有效地利用形成在第一旋转电机MG1和第二旋转电机MG2之间的凹进空间,被安装到变速驱动桥外壳2的PCU 10的高度(安装高度)可以降低到更低,并且因此可以改善PCU 10的布置。
在PCU组件10A被放置在PCU安装部20中之后,PCU盖18被固定到PCU安装部20的顶部以覆盖开口部分20f。因此,可以抑制异物对PCU 10的污染。
在第一实施例中,PCU 10可以被构造成使得在PCU 10中包括的一些部件位于安装区域F2之外。
此外,在第一实施例中,其中布置有第一旋转电机MG1和第二旋转电机MG2的变速驱动桥外壳2的内部通过后壁部分20b和底壁部分20c与其中安装有PCU 10的PCU安装部20的内部分隔开。在第一实施例中,PCU 10的直流-直流变换器17由水套16冷却。
图6是沿图5的线VI-VI截取的剖视图,其中PCU 10被安装在PCU安装部20中。
在第一实施例中,如图6中所示,PCU安装部20的内部被分成PCU侧空间F3和变速驱动桥侧空间F4,并且PCU侧空间F3和变速驱动桥侧空间F4彼此连通。PCU 10被布置在PCU侧空间F3中。此外,端子台40和变速驱动桥侧汇流条41被布置在变速驱动桥侧空间F4中。在第一实施例中,PCU 10侧和变速驱动桥100侧通过PCU安装部20中的PCU侧汇流条13和变速驱动桥侧汇流条41之间的汇流条连接彼此电连接。
变速驱动桥侧汇流条41竖直设置在端子台40的顶表面上,端子台40从变速驱动桥100侧朝向PCU 10侧从底壁部分20c部分地突出。端子台40位于被设置在PCU 10下部的直流-直流变换器17的旁边,并且在车辆左右方向上位于左侧上。如图7中所示,端子台40可以位于被设置在PCU 10下部的直流-直流变换器17的旁边,并且在车辆左右方向上位于右侧上。
在第一实施例中,其可以构造成端子台40和变速驱动桥侧汇流条41不与包括在PCU 10中的相应部件接触,并且同时,当端子台40位于PCU 10的直流-直流变换器17的下方时,被安装到变速驱动桥外壳2的PCU 10的高度(安装高度)可以减小到低于PCU 10的高度。
在下文中,将描述根据本发明的车辆驱动系统的第二实施例。在第二实施例中,将适当省略对与第一实施例相同的部件的描述。
图8是垂直于未安装PCU 210的变速驱动桥外壳2的轴向方向的剖视图。图9是垂直于安装有PCU 210的变速驱动桥外壳2的轴向方向的剖视图。图10是沿图9的线X-X截取的安装有PCU 210的PCU安装部220的视图。
如图8、图9和图10中所示,在第二实施例的车辆驱动系统中,具有安装有PCU 210的安装区域F5的PCU安装部220被设置在作为变速驱动桥外壳2顶部的外周壁部2a的外周表面上。PCU安装部220被构造成具有盒状形状(其具有开口上表面),并且包括在车辆前后方向上彼此面对的前壁部分220a和后壁部分220b、在车辆左右方向上彼此面对的右壁部分220d和左壁部分220e、形成PCU安装部220的底部的底壁部分220c、以及允许上表面打开的开口220f。后壁部分220b和底壁部分220c是变速驱动桥外壳2的外周壁部2a的一部分。后壁部分220b在车辆前后方向上相对于底壁部分220c向后倾斜,并且在垂直于变速驱动桥外壳2的轴向方向的横截面上具有限定在后壁部分220b和底壁部分220c之间的钝角。此外,由后壁部分220b和底壁部分220c限定的拐角部分位于形成在第一旋转电机MG1和第二旋转电机MG2之间的凹进空间中。
第二实施例的PCU安装部220的前壁部分220a、后壁部分220b、右壁部分220d和左壁部分220e的相应高度低于第一实施例的PCU安装部20的对应前壁部分20a、后壁部分20b、右壁部分20d和左壁部分20e的相应高度。
图11是PCU 210的分解图。如图11中所示,PCU 210包括控制板211、电力堆叠体212、PCU侧汇流条213、电抗器214、电容器215、水套216、直流-直流变换器217、PCU盖218等。PCU盖218具有盒状形状(其具有开口下表面),并且被安装到PCU安装部220的顶部,以便封闭开口220f。此外,PCU盖218具有在车辆前后方向上从车辆后侧朝向车辆前侧逐渐变深的深度,并且该深度被设置为足够深以包围稍后描述的PCU组件210A的大部分周边。
在第二实施例中,PCU 210在高度方向上具有多层结构,并且被构造为PCU组件210A,该PCU组件210A通过在PCU 210的高度方向上从下侧(变速驱动桥100侧)依次堆叠和集成直流-直流变换器217、水套216、电抗器214和电容器215、电力堆叠体212和控制板211而形成。在PCU组件210A中,电力堆叠体212、电抗器214和电容器215以及直流-直流变换器217被紧固到水套216。
此外,在PCU组件210A中,电抗器214和电容器215、水套216和直流-直流变换器217顺序堆叠在电力堆叠体212的下方。因此,例如,与电抗器214和电容器215以及直流-直流变换器217在水套216的下方以平坦方式并排布置的情况相比,PCU组件210A被布置成更向下突出(朝向变速驱动桥100侧)。
然后,当PCU 210被安装在PCU安装部220中时,PCU组件210A首先被附接在PCU盖218中。然后,其中附接有PCU组件210A的PCU盖218被固定到PCU安装部220的顶部,以便覆盖PCU安装部220的开口220f。
此时,在PCU安装部220中,PCU组件210A的下部的一部分,例如电抗器214和直流-直流变换器217的相应部分,位于形成在第一旋转电机MG1和第二旋转电机MG2之间的凹进空间中。
具体而言,如图9中所示,当PCU 210被安装在PCU安装部220中时,PCU 210的下部的一部分位于由线D、第一旋转电机MG1和第二旋转电机MG2包围的空间内,其中线D通过连接第二旋转电机MG2在垂直方向上的中心线和变速驱动桥壳2之间的交点B和与第一旋转电机MG1在水平方向上的中心线相交的第一旋转电机MG1的切线和变速驱动桥壳2之间的交点C来限定。换句话说,在垂直于变速驱动桥外壳2的轴向方向的横截面中,PCU 210的下部的一部分位于由PCU安装部220的后壁部分220b和底壁部分220c以及线D包围的区域F6内。
因此,在将PCU 210安装到变速驱动桥外壳2上时,有效地利用了形成在第一旋转电机MG1和第二旋转电机MG2之间的凹进空间,由此将安装到变速驱动桥外壳2上的PCU 210的高度降低到更低,并改善PCU 210的布置。
这里,在第二实施例中,在将PCU 210安装到变速驱动桥外壳2上时,在PCU组件210A被安装在设置到变速驱动桥外壳2上的PCU安装部220中而没有将PCU组件210A安装在PCU盖218中之后,PCU盖218可以被固定在PCU安装部220的顶部上。这使得可以改善将PCU210安装到变速驱动桥外壳2上的可操作性。另一方面,如上所述,在PCU组件210A被附接在PCU盖218中之后,PCU 10然后被安装在PCU安装部220中,并且由此可以抑制从PCU组件210A被组装的时间到PCU 10被安装在PCU安装部220中的时间异物污染PCU组件210A。
在第二实施例中,PCU 210侧和变速驱动桥100侧通过PCU安装部220的内部的PCU侧汇流条213和变速驱动桥侧汇流条241之间的汇流条连接彼此电连接。
变速驱动桥侧汇流条241被设置到端子台240,端子台240从变速驱动桥100侧朝向PCU 210侧从底壁部分220c部分地突出,如图10中所示。端子台240位于在PCU 210的下部处的直流-直流变换器217的旁边,并且在车辆左右方向上的右侧上。端子台240可以位于PCU210下部的直流-直流变换器217的旁边,并且在车辆左右方向上的左侧上。
在第二实施例中,其可以构造成使得端子台240和变速驱动桥侧汇流条241不与被包括在PCU 210中的相应部件接触,并且同时,在端子台240位于PCU 210的直流-直流变换器217的下方的情况下,被安装到变速驱动桥外壳2的PCU 210的高度(安装高度)可以减小到低于PCU 210的高度。
图12是示出在PCU 210相对于水平方向倾斜的情况下PCU 210被安装在PCU安装部220中的情况的视图。在第二实施例中,如图12中所示,在PCU 210相对于水平方向倾斜的情况下,PCU 210可以被安装在PCU安装部220中。
然后,在这种状态下,如图12中所示,在与变速驱动桥外壳2的轴向方向垂直的横截面中,PCU 210的下部的一部分位于由PCU安装部220的后壁部分220b和底壁部分220c以及线D包围的区域F7内。在图12中,直流-直流变换器217的一部分位于区域F7内。
如图12中所示,通过将PCU 210布置成相对于水平方向倾斜,将PCU 210的下部的一部分布置在区域F7内,并将PCU 210安装在PCU安装部220中,安装到变速驱动桥外壳2的PCU 210的高度(安装高度)可以降低到更低。
此外,在PCU 210相对于变速驱动桥外壳2倾斜的情况下,例如,其可以构造成使得电抗器214和电容器215在纵向方向上延伸,以便被包含在图12中的框架Z中,使得电抗器214和电容器215以平坦的方式布置,以便将PCU 210的高度降低到更低。
图13是示出PCU 210没有设置直流-直流变换器217的情况的视图。在第二实施例中,如图13中所示,PCU 210可以不设置有直流-直流变换器217。在这种情况下,例如,如图13中所示,当PCU 210以相对于水平方向倾斜的状态被安装到PCU安装部220中时,电容器215在PCU 210的电力堆叠体212的下方朝向变速驱动桥外壳2侧布置。此外,电抗器214在电力堆叠体212的纵向方向上布置,使得电抗器214与在电力堆叠体212中包括的冷却器接触。
然后,如图13中所示,在与变速驱动桥外壳2的轴向方向垂直的横截面中,PCU 210的下部的一部分位于由PCU安装部220的后壁部分220b和底壁部分220c以及线D包围的区域F8内,并且PCU 210被安装在PCU安装部220中。在图13中,电容器215的一部分位于区域F8内。
如图13中所示,虽然没有设置直流-直流变换器217的PCU 210被布置成相对于水平方向倾斜的状态,并且PCU 210的下部(电容器215)的一部分位于区域F8内,但是PCU 210被安装在PCU安装部220中,由此将安装到变速驱动桥外壳2的PCU 210的高度降低到更低。
