发明内容
发明所要解决的课题
然而，在上述那样的混合动力型的车辆中，需求车辆运动性能的进一步的提升。在试图提升车辆的运动性能的情况下，有效的是在车辆中的距离中央较近的区域配置将发动机以及电机单元化而成的驱动单元。通过这样配置驱动单元，车辆变得容易转弯，能够实现车辆运动性能的提升。但是，由于在车辆中的距离中央较近的区域存在乘员空间，因此用于搭载驱动单元的空间受限。由此，为了实现车辆运动性能的提升需要实现驱动单元的小型化。
此外，在为了车辆行驶而驱动驱动单元时，产生以驱动轮为起点的驱动单元的振动(上下方向的位移)，出于车辆运动性能的提升以及确保乘员的舒适性这一观点，希望尽可能小地抑制驱动单元的驱动时的振动。为了实现该目的，需要使驱动单元小型化，并在车辆中的距离中央较近的区域配置驱动单元。即，例如在将后轮设为驱动轮的情况下，若在车辆中的距离中央较近的区域配置驱动单元，则与在车辆中的前方的区域配置驱动单元的情况相比，驱动轮与驱动单元的前端(与驱动轮相反一侧的端部)之间的距离变短，驱动单元的上下方向的位移(振动)变小。
本发明为了解决上述那样的问题而完成，目的在于提供将具有发动机以及电机的驱动单元的振动抑制得较小，具备较高的车辆运动性能的车辆。
用于解决课题的手段
首先，本发明人等认真研究了用于将驱动单元的驱动时的振动抑制得较小，实现较高的车辆运动性能的方案。
在驱动单元的驱动时，以驱动轮为起点的振动的产生原因在于发动机。
因此，本申请发明人等首先研究了对发动机的壳体直接结合电机的壳体而成的构造。考虑到通过对发动机壳体直接结合电机壳体，从而对发动机附加电机的重量，能够抑制发动机的振动。
但是，得知仅对发动机壳体直接结合电机壳体时，不能充分地抑制发动机在驱动时的振动。假设，在仅考虑抑制发动机的振动的情况下，只要增加电机壳体的重量即可，但在这种情况下，驱动单元整体的重量也增加，导致车辆运动性能的降低，难以采用。
接下来，本发明人等考虑到缩短驱动单元的长度、即输出轴延伸的方向上的驱动单元的尺寸。只要能够缩短驱动单元的长度，便能够缩短驱动轮与驱动单元的前端(与驱动轮相反一侧的端部)之间的距离，能够将上下方向上的位移量抑制得较小。
因此，本发明人等考虑到除了对发动机壳体直接结合电机壳体之外，还缩短驱动单元的长度、即输出轴延伸的方向上的驱动单元的尺寸，从而进一步将驱动单元小型化。只要能够缩短驱动单元的长度，便能够进一步缩短驱动轮与驱动单元的前端(与驱动轮相反一侧的端部)之间的距离，能够将上下方向上的位移量抑制得较小。
这里，在发动机中，以往在发动机输出轴设有用于抑制驱动时的振动的平衡配重。平衡配重相对于发动机的输出轴，设于该输出轴的长度方向的端部。因此，即使如上述那样试图仅将发动机壳体与电机壳体直接结合，驱动单元整体的长度也会增长设于发动机输出轴的一端侧(试图结合电机一侧)的平衡配重的厚度量。
因此，本发明人等对能够确保抑制振动的平衡配重的功能且抑制平衡配重的厚度所致的驱动单元整体的长度的放大的构造进行了深刻研究，而完成了本发明。
具体而言，本发明的一方式的车辆具备车辆行驶用的驱动源即驱动单元，该驱动单元具有彼此相邻配置的发动机以及电机，所述发动机具有输出驱动力的发动机输出轴、以及构成外壳的发动机壳体，所述电机具有转子和定子、与所述转子结合且输出驱动力的电机输出轴、以及构成外壳的电机壳体，所述发动机壳体和所述电机壳体一体形成、或者彼此结合，所述发动机输出轴和所述电机输出轴一体形成、或者以同心且同步旋转的方式彼此结合，所述电机的所述转子具有在与所述定子之间形成旋转磁场的主体部、以及作为所述发动机的平衡配重发挥功能的配重部。
在上述方式的车辆中，由于具备发动机与电机单元化而成的驱动单元，因此与发动机和电机未被单元化的情况相比，能够实现驱动源的小型化，能够在车辆的中央或者其附近配置驱动单元。具体而言，在上述方式的车辆中，由于将发动机壳体与电机壳体一体形成或者结合，并将发动机输出轴与电机输出轴一体形成或者结合，因此与在发动机和电机之间隔开间隔地配设的情况相比，特别是能够缩短长度(发动机输出轴以及电机输出轴的轴向上的尺寸)。由此，在上述方式的车辆中，能够实现车辆运动性能的提升及驱动单元的振动降低。
此外，在上述方式的车辆中，由于将发动机壳体与电机壳体一体形成或者结合，因此能够对发动机附加电机的重量。由此，能够进一步抑制在发动机驱动时产生的振动(上下移动)。
另外，在上述中“一体形成”意为由单一的部件一体地构成。具体而言，“发动机壳体与电机壳体一体形成”意为将单一的壳体的一部分设为发动机壳体，将该壳体的其他部分设为电机壳体的状态。同样，“发动机输出轴与电机输出轴一体形成”意为将单一的轴的一部分设为发动机输出轴，将该轴的其他部分设为电机输出轴的状态。
此外，在上述方式的车辆中，电机的转子具有配重部，该配重部作为发动机的平衡配重发挥功能。即，由于发动机的平衡配重与转子一体化，因此与在发动机输出轴上不同于电机的转子地另行设置平衡配重的情况相比，能够缩短驱动单元的长度。由此，能够进一步抑制在发动机驱动时以驱动轮为起点产生的驱动单元的振动(上下移动)。
在上述方式的车辆中也可以是，所述发动机壳体和所述电机壳体以所述发动机壳体的所述电机壳体侧的端面与所述电机壳体的所述发动机壳体侧的端面对接的状态结合，在所述发动机和所述电机的相邻方向上，所述转子中的所述配重部的一部分成为比所述发动机壳体与所述电机壳体的对接面更向所述发动机壳体侧侵入的状态。
在上述方式的车辆中，由于以配重部的一部分成为与上述对接面相比向发动机壳体侧侵入的状态的方式，形成有转子的配重部，因此能够有效利用使该配重部比上述对接面更向发动机壳体侧侵入的部分所相应的空间。由此，在上述方式的车辆中，能够缩短驱动单元的长度(发动机输出轴以及电机输出轴的轴向上的尺寸)，进一步有助于抑制以驱动轮为起点的驱动单元的振动(上下移动)。
在上述方式的车辆中也可以是，在将与所述电机输出轴所延伸的方向正交的方向设为径向时，在包含所述电机输出轴的轴心的剖面上观察所述转子的所述配重部的情况下，该配重部具有从所述电机输出轴一侧且与所述发动机壳体相反的一侧朝向所述径向的外侧且所述发动机壳体侧倾斜地延伸的中间部、以及与所述中间部连续且向所述径向的外侧延伸的外缘部。
在上述方式的车辆中，由于以具有向发动机壳体侧倾斜向外地延伸的中环部的方式形成有配重部，因此能够避免电机壳体内的定子等与配重部的干扰。
在上述方式的车辆中也可以是，所述配重部的所述外缘部被设置成，该外缘部的外周面位于比所述主体部的外周面更靠所述径向的外侧的位置。
在上述方式的车辆中，由于设为配重部中的外缘部的外周面与主体部的外周面相比位于径向外侧，因此容易抑制发动机驱动时的振动，作为转子的一部分而设的配重部作为发动机的平衡配重有效地发挥功能。
在上述方式的车辆中也可以是，所述配重部的所述外缘部被设置成，该外缘部的外周面位于比所述定子的内周面更靠所述径向的外侧的位置。
在上述方式的车辆中，由于设为配重部中的外缘部的外周面与定子的内周面相比位于径向外侧，因此更容易抑制发动机驱动时的振动，作为转子的一部分而设的配重部作为发动机的平衡配重有效地发挥功能。
在上述方式的车辆中也可以是，所述发动机还具有单元端平衡配重，该单元端平衡配重结合于所述发动机输出轴上的、所述电机所相邻的一侧的相反侧的部分，所述配重部设置成半径大于所述单元端平衡配重的半径。
在上述方式的车辆中，由于在发动机输出轴设有单元端平衡配重，因此与仅通过电机中的转子的配重部抑制发动机驱动时的振动的情况相比，能够更可靠地抑制发动机的振动(上下移动)。
在上述方式的车辆中也可以是，所述配重部以旋转相位与所述单元端平衡配重大致为相反相位的方式设置。
在上述方式的车辆中，由于将转子中的配重部、与单元端平衡配重的旋转相位设为大致相反相位(大致180deg.)，因此能够有效地抑制发动机的振动。
在上述方式的车辆中也可以是，在从所述电机输出轴的轴向的一方观察所述配重部的情况下，该配重部具有扇形状。
在上述方式的车辆中，由于将转子中的配重部设为扇形状，因此能够调整发动机输出轴以及电机输出轴的周向上的配重的分布，有助于进行更可靠的振动抑制。
在上述方式的车辆中也可以是，所述发动机输出轴与所述电机输出轴直接结合。
在上述方式的车辆中，由于使发动机输出轴与电机输出轴直接结合，因此与经由联轴器等将发动机输出轴与电机输出轴连接的情况相比，难以产生发动机输出轴与电机输出轴之间的旋转相位的偏差，有助于使转子中的配重部作为抑制发动机振动的平衡配重稳定地发挥功能。
在上述方式的车辆中也可以是，所述发动机是具有旋转活塞的旋转式发动机。
如上述那样，在采用旋转式发动机作为发动机的情况下，与采用往复式发动机作为发动机的情况相比，能够实现驱动单元的小型化。旋转式发动机与往复式发动机相比，被以较高的发动机转速使用，故发动机振动较大，但如上述那样，通过缩短驱动单元的长度，能够将驱动单元配置于车辆的更中央侧，因此能够缩短驱动轮与驱动单元的前端(与驱动轮相反一侧的端部)之间的距离，驱动单元的上下振动被抑制得足够小。
在上述方式的车辆中也可以是，所述驱动单元包含多个所述旋转式发动机，所述发动机壳体具有筒形状，并且收容有多个所述旋转活塞，所述电机壳体具有筒形状，并且收容有所述转子以及所述定子，所述发动机壳体与所述电机壳体通过紧固机构直接结合。
如上述那样，通过紧固机构将筒形状的发动机壳体、与同为筒形状的电机壳体直接紧固，从而能够实现驱动单元的小型化。因此，在采用上述构成的情况下，能够将驱动单元配置于车辆的更中央侧，能够缩短驱动轮与驱动单元的前端(与驱动轮相反一侧的端部)之间的距离。由此，在采用上述构成的情况下，能够更可靠地抑制驱动单元的上下振动。
发明效果
在上述的各方式的车辆中，具有发动机以及电机的驱动单元的振动被抑制得小，具备较高的车辆运动性能。

具体实施方式
以下，参照附图对本发明的实施方式进行说明。另外，以下说明的方式是本发明的一例，除了本质上的构成之外，本发明不限于以下任一方式。
此外，在以下的说明所使用的附图中，“F”表示车辆前方，“R”表示车辆后方，“U”表示车辆上方，“L”表示车辆下方，“Le”表示车辆左方，“Ri”表示车辆右方。
[实施方式]
1.车辆1的概略构成
使用图1对本实施方式的车辆1的概略构成进行说明。
如图1所示，在车辆1中，用于驱动该车辆1的驱动单元10搭载于前侧区域1a中的后方侧部分。驱动单元10具有发动机11～13以及电机14。后述驱动单元10的详细的构造。
在驱动单元10的输出轴(电机14的电机输出轴)连接有传动轴15。传动轴15从车辆1的车宽方向中央向后方侧延伸。传动轴15的后端连接于变速器16。
在变速器16连接有差动齿轮17。而且，在差动齿轮17的车宽方向左右分别连结有驱动轴18、19。驱动轴18、19分别连接于后轮(驱动轮)20、21。即，在本实施方式的车辆1中，通过搭载于前侧区域1a的驱动单元10产生的驱动力来驱动作为驱动轮的后轮20、21，从而行驶。
此外，在车辆1中前轮22、23分别连接有电机24、25。虽然省略了详细的图示，但电机24、25是所谓的轮毂电机。电机24、25作为在车辆1的起步时产生动力并向前轮22、23传递的辅助电机发挥功能。此外，电机24、25也作为在车辆1的减速时发电的再生制动器发挥功能。而且，在车辆1的减速时通过电机24、25产生的电力向电容器28等充电。
在车辆1也搭载有电池26以及逆变器27。电池26是用于对驱动单元10的电机14供电的蓄电模块。本实施方式的电池26例如为锂离子电池。来自电池26的电力经由逆变器27向电机14供给。
这里，在本实施方式的车辆1中，作为驱动单元10的驱动模式，具备发动机驱动模式与电机驱动模式。发动机驱动模式是通过从发动机11～13输出的驱动力驱动后轮(驱动轮)20、21来行驶的模式。电机驱动模式是通过从电机14输出的驱动力驱动后轮(驱动轮)20、21来行驶的模式。
另外，在车辆1中构成为，在通过发动机驱动模式驱动时电机14不产生驱动力，在通过电机驱动模式驱动时发动机11～13不产生驱动力。
在车辆1中，发动机驱动模式与电机驱动模式的切换控制由驱动模式控制部29进行。驱动模式控制部29具备具有CPU、ROM、RAM等的微处理器而构成。驱动模式控制部29基于来自驾驶员的指示、车辆1的状况(车速、加减速度、电池剩余容量)等执行驱动模式的控制。
2.驱动单元10的搭载位置
使用图2对车辆1中的驱动单元10的搭载位置进行说明。
如上述那样，在车辆1中，驱动单元10搭载于前侧区域1a的后方侧部分。具体而言，以驱动单元10的重心Ax10与前轮22、23(在图2中仅图示出前轮23)的旋转中心Ax23相比位于靠后方侧的方式搭载有驱动单元10。此外，驱动单元10以重心Ax10与前轮22、23的旋转中心Ax23相比位于靠下方侧的方式搭载。
即，在车辆1中，通过将作为重量物的驱动单元10紧凑化，从而使该驱动单元10搭载于前侧区域1a的后方侧部分且与机罩30隔开间隔的下方侧部分。由此，能够将车辆1的重心位置Ax1设于车辆1的长度方向的大致中央的较低位置。
3.驱动单元10及其周边的构成
使用图3以及图4对驱动单元10的详细构成及其周边的构成进行说明。
如图3以及图4所示，驱动单元10具有的发动机11～13为具有旋转活塞的旋转式发动机。在车辆1中，通过采用旋转式发动机作为发动机11～13，从而有助于实现驱动单元10的小型化。
如图4所示，在发动机11～13的下方配设有油盘38。油盘38具有高度方向的尺寸相对于车辆前后方向以及车宽方向的尺寸较小的扁平形状。由此，有助于将驱动单元10的高度抑制得较低。
如上述那样，在本实施方式的车辆1中油盘38具有扁平形状，因此机油的收容容量较少。因此，主要的功能是收集在发动机11～13中流通的机油。由此，在驱动单元10的侧方设有用于存储通过油盘38收集的机油的油罐35。
如图3以及图4所示，在驱动单元10的前方配设有散热器31以及油冷却器32。散热器31是用于冷却由于发动机11～13的热量而成为高温的冷却水的设备，并在后方侧具有散热器风扇31a。
油冷却器32配置于散热器31的后方，以沿着散热器31的方式配设。与散热器31相比，油冷却器32的平面尺寸较小。发动机11～13与散热器31之间通过配管36、37连接。在配管37与发动机11～13的连接部分设有水泵34。
油冷却器32、发动机11～13、油罐35、以及油盘38彼此间通过配管39～41等连接。在配管41与发动机11～13的连接部分设有油泵33。
驱动单元10中的电机14与发动机13的后方相邻地配置。发动机11～13与电机14为共有输出轴的直接连结构造。在车辆1的上下方向以及车宽方向上，电机14的外观尺寸形成得比发动机11～13小。
在电机14中的后端侧的端面结合有扭矩管42。
4.驱动单元10中的发动机11～13与电机14的结合构造
使用图5对驱动单元10中的发动机11～13与电机14的结合构造进行说明。
如图5所示，发动机11～13共有构成外壳的发动机壳体131。发动机壳体131为筒形状的部件，在内部收容有旋转活塞、发动机输出轴。
此外，电机14具有构成外壳的电机壳体141。电机壳体141也为筒形状的部件，在内部收纳有转子与定子、电机输出轴。
发动机壳体131与电机壳体141在车辆1的前后方向上对接(对接面A-A)，并通过多个螺栓(紧固机构)43直接结合。另外，“直接结合”不仅指发动机壳体131的突缘面与电机壳体141的突缘面以直接抵接的状态结合的情况，还包括发动机壳体131与电机壳体141以其间介有密封件的状态结合的情况。
5.电机14的内部构成
使用图6对电机14的内部构成进行说明。
如图6所示，在发动机壳体131的内部收容有沿车辆1的前后方向延伸的发动机输出轴132。此外，发动机壳体131内部，在与电机14的边界部分还收容有环状的油封133。
与发动机输出轴132同样，在电机壳体141的内部收容有沿车辆1的前后方向延伸的电机输出轴142、结合于电机输出轴142的外周的转子143、以及定子145。此外，在电机壳体141的内部，在与发动机13的边界部分还收容有环状的油封144。
在发动机壳体131与电机壳体141中，发动机壳体131的后端面131a与电机壳体141的前端面141a以对接面A-A对接，并利用多个螺栓(紧固机构)43直接结合(参照图5)。
发动机输出轴132与电机输出轴142以发动机输出轴132的轴心Ax132与电机输出轴142的轴心Ax142同心且同步旋转的方式直接结合。即，在发动机11～13与电机14中，发动机输出轴132与电机输出轴142直接连结。
电机14的转子143结合于电机输出轴142，并具有向发动机13侧(前方侧)延伸设置的配重部143a、以及配设于定子145的径向内侧的主体部143b。转子143的主体部143b是在与定子145之间产生旋转磁场的部件。在本实施方式中，作为一例，转子143的主体部143b为永磁体，定子145为线圈。
6.转子143中的配重部143a的构造
使用图7以及图8对转子143中的配重部143a的构造进行说明。
如图7所示，配重部143a与主体部143b以及定子145相比靠前方侧(发动机壳体131的内部空间131b侧)地配设于转子143。配重部143a从电机输出轴142一侧起依次具有中间部143c与外缘部143d。中间部143c以随着从电机输出轴142一侧向径向外侧、从后方侧向前方侧地沿倾斜方向延伸的方式设置。外缘部143d以相对于中间部143c在其外周部分连续、且向径向外侧延伸的方式设置。外缘部143d设置得比中间部143c壁厚。
另外，在本说明书中“径向”指的是与发动机输出轴132的轴心Ax132(参照图6)以及电机输出轴142的轴心Ax142(图6参照)正交的方向。
如图8所示，在从前方侧正视电机14的情况下，转子143的配重部143a呈大致扇形状。转子143将配重部143a包含在内地与电机输出轴142一体地绕轴心Ax142旋转。
返回图7，外缘部143d的前端面143f相比于发动机壳体131与电机壳体141的对接面A-A，位于发动机壳体131侧。换言之，配重部143a中的外缘部143d的一部分(前方侧部分)为，相比于发动机壳体131与电机壳体141的对接面A-A，侵入发动机壳体131侧(前方侧)的状态。
另外，虽然在发动机壳体131与电机壳体141的对接面A-A上的径向内侧配设有油封144，但由于配重部143a具有沿倾斜方向延伸的中间部143c，因此防止了配重部143a与油封144之间的干扰。
从电机输出轴142的轴心Ax142(在图7中省略了图示)至外缘部143d的外周面143e的距离(半径)Ra对于从轴心Ax142至主体部143b的外周面143g的距离(半径)Rb满足以下关系。
Ra＞Rb…(式1)
此外，半径Ra对于从轴心Ax142至定子145的内周面145a的距离(半径)Rd以及从轴心Ax142至外周面145b的距离(半径)Rc满足以下关系。
Rc＞Ra＞Rd…(式2)
7.平衡配重111的构造
在本实施方式的车辆1中，在驱动单元10的前方侧部分设有平衡配重(单元端平衡配重)111。使用图9对平衡配重111的构造进行说明。
如图9所示，设于驱动单元10的前方侧部分的平衡配重111结合于发动机输出轴132，并具有中间部111c与外缘部111d。中间部111c以从发动机输出轴132一侧向径向外侧延伸的方式设置。另外，在平衡配重111中，中间部111c以沿与发动机输出轴132的轴心Ax132正交的方向延伸的方式设置。
外缘部111d以相对于中间部111c在其外周部分连续且向径向外侧延伸的方式设置。外缘部111d设置得比中间部111c壁厚。
另外，虽然在图9中省略了图示，但平衡配重111在主视时也具有扇形状。
这里，在本实施方式的车辆1中，从发动机输出轴132的轴心Ax132至外缘部111d的外周面的距离(半径)Re对于上述半径Ra满足以下关系。
Re＜Ra…(式3)
[变形例]
在上述实施方式的车辆1中，设为分别形成发动机壳体131与电机壳体141，并通过对接面A-A对接而结合，但本发明不限于此。在本发明中，也能够采用将发动机壳体与电机壳体一体成型而成的构造，即将单一的壳体的一部分设为发动机壳体，将该壳体的其他部分设为电机壳体的构造。
此外，在上述实施方式的车辆1中，设为分别形成发动机输出轴132与电机输出轴142，以轴心Ax132与轴心Ax142同心并且同步旋转的方式彼此直接结合，但本发明不限于此。在本发明中，也能够采用将发动机输出轴与电机输出轴一体形成的构造，即将单一的轴的一部分设为发动机输出轴，将该轴的其他部分设为电机输出轴的构造。
而且，也可以设为将联轴部件介于之间地结合发动机输出轴与电机输出轴。但是，在采用该构成的情况下，使发动机输出轴与电机输出轴的旋转相位相同。
在上述实施方式中，在驱动单元10的前方侧部分设置了平衡配重(单元端平衡配重)111，但在本发明中，也可以不设置单元端平衡配重。
此外，在上述实施方式中，设为平衡配重111与电机14中的转子143的配重部143a在主视时均具有扇形状，但平衡配重111以及配重部143a在主视时的形状不限于此。也可以是矩形条状、半椭圆形状等。
此外，在上述实施方式中，设为转子143中的配重部143a具有中间部143c与外缘部143d，但在能够避免与周边的部位的干扰的条件下能够采用各种截面形状。例如也能够采用具有阶梯状的截面形状的配重部。
此外，在上述实施方式中，未特别提及平衡配重111与配重部143a的旋转相位，但能够考虑发动机的振动特性等来决定。例如也能够将平衡配重111与配重部143a的旋转相位设为大致相反的相位。这里，上述中的“大致”这一词语的含义也包括例如相对于相反相位(相位差为180deg.)存在小于1deg.的偏差(差异)的情况。
在上述实施方式中，作为发动机11～13的一例采用了旋转式发动机，但在本发明中也能够采用往复式发动机。在采用往复式发动机作为发动机的情况下，通过将相当于往复式发动机的平衡配重的飞轮与电机中的转子一体化，从而能够获得与上述实施方式相同的效果。
在上述实施方式中，作为车辆1的一例采用了FR车，但本发明不限于此。例如也能够采用在后部搭载驱动单元，向后轮传递驱动力的RR车，或在驾驶座的后部搭载驱动单元，向后轮传递驱动力的MR车，并且能够采用在前侧区域的后方侧部分搭载驱动单元，向前轮传递驱动力的FF车。
