在电动机32中,通过对线圈供应三相交流电,从而产生在周向上旋转的旋转磁场。定子通过使所产生的磁通与转子交链,从而使与电动机轴32B为一体的转子旋转驱动。
在图1、图4中,在变速器壳体5设置有减速机构收纳部25。在图1中,减速机构收纳部25由后述的左壳体7的鼓出部7H和罩构件27形成。在图4中,减速机构收纳部25形成有减速机构收纳室25A,在减速机构收纳室25A中收纳有减速机构33。

左壳体7在其左端部具有向上方鼓出的鼓出部7H。左壳体7的左端部的开口由于鼓出部7H而向上方扩大。鼓出部7H是构成减速机构收纳部25的壳体部分,并且在其左侧配置减速机构33。
如图1、图2所示,罩构件27通过螺栓23B(参照图1)接合(紧固)到左壳体7的左端部,将还包含鼓出部7H的部分在内的左壳体7的左端部的开口封闭。也就是说,由鼓出部7H和配置于鼓出部7H的左侧的罩构件27从左右形成成为减速机构33的收纳空间的减速机构收纳部25。
在图1、图2中,在鼓出部7H的上端部,在其发动机8侧(右侧)设置有电动机装配部29C。电动机装配部29C形成为圆形的凸缘状,其直径从鼓出部7H的上部(详细地说是鼓出部7H的上部的左端部)扩大至与电动机32的外径即电动机壳体32A的外径相等的外径。
在电动机装配部29C的外周部设置有多个凸台部29m,凸台部29m沿着电动机装配部29C的外周部设置。通过使螺栓23C插通于电动机装配部29C,将螺栓23C紧固到形成于电动机壳体32A的未图示的螺纹孔,从而电动机32被紧固到电动机装配部29C。
在图1、图2中,在比电动机32靠前侧的左壳体7的上部设置有换挡单元41。在俯视车辆1时,电动机32和换挡单元41以靠近安装件装配部31的方式设置于安装件装配部31的前后。
换挡单元41为了进行驱动装置4的换挡操作和离合器操作而被驱动。在此,换挡操作是指对驱动装置4的变速挡进行切换的操作,离合器操作是指将驱动装置4的离合器10卡合(连接)或者释放(切断)的操作。
在图4中,在左壳体7收纳有换挡选择轴42。换挡选择轴42相对于左壳体7在轴心方向上移动自如并且旋转自如,由换挡单元41操作。
在由驾驶员操作的未图示的换挡杆被切换到前进挡位的状态或者被切换到后退挡位的状态中,换挡单元41例如基于预先设定了节气门开度和车速作为参数的变速映射来操作换挡选择轴42。
换挡选择轴42通过包括均未图示的变速叉(shift yoke)、换挡轴以及换挡拨叉(shift fork)等变速操作机构操作第1同步装置18至第4同步装置21来进行变速挡的控制。此外,换挡单元41通过油压机构或马达机构等操作换挡选择轴42,但驱动方式不限于这些油压机构或马达机构等。
如图1、图2所示,在变速器壳体5设置有前支架46A和后支架46B。前支架46A连结电动机32与右壳体6,将电动机32支撑于右壳体6。
后支架46B连结电动机32与右壳体6,将电动机32支撑于右壳体6。这样,电动机32的轴方向上的一端装配到电动机装配部29C,轴方向上的另一端连结到右壳体6。
在电动机32的后方设置有:受电部32D,其从电动机32的另一端侧(右侧端部)向径向外侧后方突出,接受电动机32所使用的电力;以及连接器32C,其在受电部32D的左侧面(成为电动机32的一端侧的面)上朝向电动机32的一端侧,在连接器32C连接有用于驱动电动机32的电源线(省略图示)。
在左壳体7的左侧上部设置有安装件装配部31。安装件装配部31具有多个凸台部31A,在凸台部31A紧固有固定在车体2的未图示的安装装置。从而,驱动装置4通过安装装置弹性地支撑于车体2。
电动机32在比安装件装配部31靠后侧处与左壳体7的上表面分开,配置在左壳体7的上方。发动机8通过发动机用的未图示的安装装置弹性地支撑于车体2。
在图5中,减速机构收纳部25具有:筒状的环状壁7J,其从周向包围减速机构33;以及分隔壁7K,其沿轴方向对减速机构收纳部25进行分隔。另外,减速机构收纳部25具有对减速机构33的上部配送油的油管71,油管71配置在减速机构收纳部25的内部的减速机构收纳室25A。另外,油管71配置成沿着环状壁7J的内周面延伸至减速机构33的上方。此外,油管71配置在减速机构收纳室25A中的由罩构件27(参照图2)形成的部分。
在本实施例中,在变速器壳体5的较高的位置配置有电动机32,在电动机32与变速机构61的前进用输出轴12之间配置有减速机构33。因此,难以通过将油带起而对减速机构33进行润滑,采取了通过使用油泵73对油进行泵送而对减速机构33进行润滑。
油管71将由油泵73泵送的油滴到第1驱动齿轮34。滴到第1驱动齿轮34的油对位于第1驱动齿轮34的下方的第1从动齿轮35A、第2驱动齿轮35B、第2从动齿轮36A、第3驱动齿轮36B进行润滑。
油管71的油流动方向的下游端部71C位于设置在减速机构33的最上部的电动机轴32B的第1驱动齿轮34的上方。油管71在其油流动方向的上游端部71A、以及紧固部71B固定于减速机构收纳部25。油管71的上游端部71A贯通分隔壁7K并固定到该分隔壁7K。详细地说,上游端部71A通过摩擦固定到分隔壁7K。
另外,电动机轴32B、第1中间轴35、第2中间轴36以及前进用输出轴12设置成连结电动机轴32B的轴心O1、第1中间轴35的轴心O2、第2中间轴36的轴心O3以及前进用输出轴12的轴心O4的假想线L成为之字形状,油管71配置成沿着假想线L弯曲。
另外,在油管71与环状壁7J之间设置有紧固用凸台7L,油管71在其紧固部71B中通过支架72以紧固的方式固定到紧固用凸台7L。紧固用凸台7L以从分隔壁7K立起的方式形成,并且与环状壁7J连结。油管71也可以通过紧固以外的方法例如嵌入等而固定到分隔壁7K或环状壁7J。在支架72设置有与环状壁7J相对的突起72A。当在使支架72面对紧固用凸台7L时支架72发生了旋转的情况下,突起72A会与环状壁7J相撞,阻止支架72的旋转。从而,能够防止由于支架72旋转而引起的油管71的变形。
此外,在本实施例中,减速机构33具有第1中间轴35和第2中间轴36这2个中间轴,但也可以在减速机构33设置3个以上的中间轴。
接着,说明作用。在车辆1前进时以发动机行驶时,发动机8的动力从输入轴11通过使规定的变速挡成立的输入齿轮16A至输入齿轮16F中的任意一者传递到输出齿轮17A至输出齿轮17F中的任意一者。
从而,动力从前进用输出轴12的末级驱动齿轮17G传递到末级从动齿轮15A,发动机8的动力通过差动装置15的差动机构15C分配到左右的驱动轴24L、24R后传递到驱动轮,车辆1进行前进行驶。
另一方面,在车辆1的前进中使电动机32的驱动力发挥作用时,电动机32的动力从电动机轴32B通过第1驱动齿轮34传递到第1从动齿轮35A。
接下来,电动机32的动力通过第2驱动齿轮35B、第2从动齿轮36A以及第3驱动齿轮36B传递到4挡用的输出齿轮17D。
减速机构33将电动机32的旋转速度进行减速后传递到前进用输出轴12。
从而,动力从前进用输出轴12的末级驱动齿轮17G传递到末级从动齿轮15A,车辆1进行前进行驶。这样,电动机32的动力不通过同步装置(第1同步装置18至第4同步装置21),而被传递到末级从动齿轮15A。
另外,构成减速机构33的第1驱动齿轮34、第1从动齿轮35A、第2驱动齿轮35B、第2从动齿轮36A、第3驱动齿轮36B被从油管71供应的油润滑。
根据本实施例的驱动装置4,电动机32配置在变速机构61的上方,变速器壳体5的左壳体7具有收纳减速机构33的减速机构收纳部25。另外,减速机构收纳部25具有从周向包围减速机构33的环状壁7J、以及对减速机构33的上部配送油的油管71,油管71配置在减速机构收纳部25的内部,并且配置成沿着环状壁7J的内周面延伸至减速机构33的上方。
从而,通过在变速器壳体5中的减速机构收纳部25的内部配设油管71,能够防止油管71与驱动装置4的外部的部件发生干扰。另外,通过沿着减速机构收纳部25的环状壁7J的内周面配设油管71,能够防止油管71与减速机构33等发生干扰。
其结果是,能够防止驱动装置4的外部的部件与油管71发生干扰,提高油管71的可靠性。
根据本实施例的驱动装置4,油管71在油流动方向的上游端部71A、以及紧固部71B固定于减速机构收纳部25。
从而,至少能够通过上游端部71A和紧固部71B来固定油管71,能够防止油管71在减速机构收纳部25的内部摆动。因此,能够防止减速机构33等与油管71发生干扰,能够提高油管71的可靠性。
根据本实施例的驱动装置4,减速机构33在电动机轴32B与前进用输出轴12之间具有第1中间轴35和第2中间轴36。
另外,电动机轴32B、第1中间轴35、第2中间轴36以及前进用输出轴12设置成连结电动机轴32B的轴心O1、第1中间轴35的轴心O2、第2中间轴36的轴心O3以及前进用输出轴12的轴心O4的假想线L成为之字形状,油管71配置成沿着假想线L弯曲。
另外,在油管71与环状壁7J之间设置有紧固用凸台7L,紧固用凸台7L形成为从分隔减速机构收纳部25的分隔壁7K沿轴方向立起,油管71通过支架72以紧固的方式固定到紧固用凸台7L。
这样,由于在油管71与环状壁7J之间设置有紧固用凸台7L,因此能够防止紧固用凸台7L与减速机构33发生干扰,能够提高组装性。
另外,由于以使假想线L为之字形状的方式设置了电动机轴32B、第1中间轴35、第2中间轴36以及前进用输出轴12,因此能够使电动机轴32B靠近前进用输出轴12,能够使驱动装置4在上下方向小型化。
而且,通过将假想线L设为之字形状,能够细微地调整第1中间轴35与第2中间轴36的位置关系,能够提高电动机轴32B的配置的自由度。
其结果是,能够将配置在变速机构61的上方的电动机32和将来自该电动机32的旋转速度进行减速后传递到前进用输出轴12的减速机构33配置在有利于抑制油管71的摆动的位置。
根据本实施例的驱动装置4,紧固用凸台7L与环状壁7J连结。
从而,由于紧固用凸台7L连结到刚性高的环状壁7J,因此,能够将紧固用凸台7L变为牢固的结构,能够提高紧固用凸台7L的紧固的可靠性。
虽然公开了本发明的实施例,但很明显,本领域技术人员能在不脱离本发明的范围的情况下加以变更。旨在将所有的这种修改以及等价物包含在所附的权利要求中。
