Description

混合动力车辆用马达的配线构造
技术领域
本发明涉及混合动力车辆(hybrid vehicle)用马达的配线构造。
背景技术
作为混合动力车辆的驱动形式，已知的方式是选择地利用内燃机的驱动力和马达的驱动力两者或其中一者。
对于根据这种驱动形式的混合动力车辆驱动装置的马达，如特开2001-25187号公报中公开的那样，使用被设置在内燃机和传动装置之间而且其转子被连接到前述内燃机的曲轴上的交流马达。
对于混合动力车辆用马达50的定子51，如图6所示，使用通过将若干定子单元56沿圆周方向布置而配置在转子57周围的环形结构，其中定子单元56通过将线圈55经绝缘部件54绕在磁极齿(teeth)53上而形成，所述磁极齿通过层叠多块磁性钢板52而构成。
该定子51通过被装入大致圆筒状的定子保持环58中而被保持为环状，在这种状态下，所述定子被容纳在铸造的马达壳体59内。而且，对于构成定子51的各定子单元56的线圈55，同相的线圈彼此通过设置在定子51轴向一端面上的圆环状集电环60相互连接。
在马达壳体59中设有沿半径方向贯通的贯通孔61，连接到各集电环60的导电部件62通过该贯通孔61并被引出到马达壳体59的外部。该导电部件62在其表面设有由如碳氟(フツ素系)树脂制成的绝缘覆膜。
而且，在马达壳体59的上部，设有连接从外部给马达50供电的电源电缆63的连接端子64，并配置容纳该连接端子64的端子盒65。前述导电部件62也连接到前述连接端子64上，因此，电源电缆63就通过导电部件62和集电环60连接到各线圈55。
该端子盒65由侧壁和罩67构成，所述侧壁通过使构成马达壳体59的材料的一部分沿径向向外延伸而围绕前述连接端子64，所述罩被如此安装以便封闭形成在该侧壁上部的开口部66，而在侧壁的另一端，具有贯通所述电源电缆63的配线贯通孔68。
这样构成的现有混合动力车辆用马达50的配线操作是这样进行的：在取下罩67且打开端子盒65的状态下，用螺栓69将从马达壳体59的贯通孔61延伸的导电部件62的一端与通过配线贯通孔68且配置在端子盒65内的电源电缆63的一端共同连接到连接端子64上。而且，在连接电源电缆63和导电部件62之后，通过关闭罩67并密封端子盒65来防止连接部分进水等。
但是，如此构成的现有混合动力车辆用马达50的配线构造具有以下的问题：
第一，由于上述构造的混合动力车辆用马达50被邻接内燃机70配置，所以安装到内燃机70上的辅机和配管等被配置在马达壳体65的表面附近，特别是，由于在从外部容易接近(アクセス)的马达壳体65的上面配置冷却水配管的接头71等，所以完全覆盖混合动力车辆用马达50的端子盒65的上面是不方便的。
即，在现有的混合动力车辆用马达50中，连接接头71成为障碍，取下端子盒65的罩67变得困难，所以在进行端子盒65内的导电部件62或连接端子64等的维修或检查时，必须将连接接头或混合动力车辆用马达50本身从内燃机70上取下。
而且，由于上述理由，一旦混合动力车辆用马达50被装配到内燃机70上之后，就难以取下端子盒65的罩67，所以必须在装配前进行端子盒65内的连接端子64和电源电缆63的连接操作。因此，在进行混合动力车辆用马达50到内燃机70的装配操作时，操作者必须在电源电缆63被连接的状态下处理混合动力车辆用马达50，所以存在操作性差这样的不便性。
第二，在从集电环60引出的导电部件62由碳氟绝缘材料覆盖的现有配线构造中，除材料本身昂贵外，当形成绝缘涂膜时，必须对不需要表面处理和绝缘处理的部位进行防护处理等，因此还存在导电部件62的实际制造耗时，且产品成本高这样的不便性。
发明内容
本发明就是鉴于上述情况而提出的，本发明的目的是提供一种混合动力车辆用马达的配线构造，其能在提高电源电缆的维修性的同时，降低产品成本。
为了实现上述目的，本发明提供以下装置。
技术方案1的发明提供了一种混合动力车辆用马达的配线构造，其为设置在内燃机和传动装置之间的混合动力车辆用马达的配线构造，其中包括：对前述混合动力车辆用马达的线圈进行集配电的导电部件；电连接该导电部件和电源电缆的连接端子；及容纳该连接端子的端子盒，设置所述导电性部件，以使前述导电部件从前述混合动力车辆用马达到前述传动装置侧延伸，前述端子盒延伸到前述传动装置侧。
根据所述发明，通过如此设置以使端子盒从马达外面延伸到邻接该马达一侧的传动装置侧，其中端子盒用于将电源电缆连接到对马达的线圈进行集配电的导电部件上，可以不重叠端子盒和连接到邻接马达另一侧的内燃机上的辅机类等。结果，能通过设置在端子盒内的连接端子进行导电部件和电源电缆的连接操作，而不与辅机等干涉。
在技术方案1记载的配线构造中，技术方案2的发明提供了一种配线构造，其中前述导电部件通过设置在前述混合动力车辆用马达的壳体中的贯通孔，并从前述混合动力车辆用马达的壳体内部朝向前述传动装置的壳体外面倾斜地设置。
根据所述发明，不使导电部件露出到马达壳体的外部，而且不进行复杂的配线布置，就可以容易地将端子盒配置在传动装置侧。
在技术方案1或技术方案2记载的配线构造中，技术方案3的发明提供了一种配线构造，其中前述端子盒被配置在连接到前述内燃机的冷却用配管和前述传动装置的壳体之间。
通常，冷却用配管到内燃机的连接通过安装在内燃机上的连接接头进行，但是根据所述发明，由于端子盒被配置在冷却用配管和传动装置的壳体之间，所以端子盒可以被配置在远离安装在内燃机上的连接接头的位置。结果，在打开端子盒并在内部的接线端子处进行导电部件和电源电缆的连接操作或维修操作时，能减少冷却用配管的连接接头与端子盒的干涉，从而可以使操作性提高。
在技术方案1至3中任一技术方案记载的配线构造中，技术方案4的发明提供了一种配线构造，其中前述导电部件由树脂制的绝缘罩覆盖，而且在该绝缘罩上设有排水孔。
根据所述发明，通过用树脂制的绝缘罩覆盖导电部件，可以便宜地实现导电部件相互间的绝缘。在这种情况下，万一水滴进入绝缘罩内，绝缘性能降低，但是根据本发明，由于在绝缘罩内设有排水孔，所以通过从该排水孔排除水滴，能保持稳定的绝缘性能。
在技术方案4记载的配线构造中，技术方案5的发明提供了一种配线构造，其中当前述导电部件连接到前述连接端子上时，在前述绝缘罩上以使导电部件和端子盒内面之间的间隙减小的方式设置一突出部。
根据所述发明，由于在导电部件连接到连接端子上时，通过在绝缘罩上设置突出部，由该突出部堵住导电部件和端子盒内面之间的间隙，所以能防止用于连接端子的紧固螺钉等从导电部件和端子盒内面之间的间隙通过贯通孔落到马达内部。结果，可以确保贯通孔的尺寸足够大，而且在配置导电部件以便它从贯通孔经过并进入端子盒内时，能使操作性提高。

如图1和2所示，根据该实施例的配线构造为设在内燃机1和传动装置2之间并连接到内燃机1的驱动轴上的混合动力车辆用马达3(以下，简单地称作马达)的配线构造，该配线构造包括作为平板状导电部件的母线6，该导电部件被连接到设置在马达3的定子4的一侧面上的集配电环5；连接端子8，其用于连接将电源(未示出)的电力供给到所述母线6的电源电缆7和前述母线6；以及容纳该连接端子8的端子盒9。图1中，符号10表示马达3的转子，其同轴地配置在定子4的内周侧上。
前述端子盒9被固定在马达壳体11的上表面，所述壳体容纳马达3及其连接部件及传感器等。马达壳体11中设置沿径向向上贯通的贯通孔12。而且，在端子盒9中，通过母线6和端子盒9内表面之间的间隙形成通到前述贯通孔12的连通路13。端子盒9如此构成，以便从马达壳体11的上面朝向传动装置2侧，即朝向传动装置壳体14的上面沿水平方向延伸，而且该端子盒9具有在传动装置壳体14上面上方竖立的侧壁15，另外，端子盒9具有罩17和固定该罩17的紧固螺钉18，所述罩17用于封闭形成在前述侧壁15上部的开口部16。
另外，在端子盒9的传动装置2侧的侧壁15上设有使电源电缆7通过端子盒9内部的连通孔19，所述电缆用于从外部电源供电。对于各相电源电缆7设置三个这样的连通孔19，如图1所示，在使电源电缆7贯通插入的状态下，通过装配安装在该电源电缆7上的套管20，能液密状态地密封这些连通孔。
前述连接端子8被容纳在前述端子盒9中，而且包括由固定在该端子盒9内的绝缘材料制成的支架21；固定在该支架21内的螺钉插入部22；和连接到该螺钉插入部22的连接螺钉23。与3相交流电的各相对应，螺钉插入部22设置在三个位置，各螺钉插入部22由设置在支架21内的隔壁24隔开，以保证相互间不会发生短路。
前述母线6为由导电材料制成的带状部件，通过压制加工等，通过冲压和弯曲成形，所述母线具有在其两端形成连接孔25a、26a的连接部25、26和连接所述连接部25、26的连结部27。由螺钉23固定，以使设置在母线6一端的连接部25的连接孔26与前述连接端子8的螺钉插入部22一致(对应)。
另外，设置在前述母线6的另一端上的连接部26与配置在马达3的定子4一侧面上的集配电环5连接。在定子4的径向向外方的马达壳体11内部固定有和前述连接端子8相同的连接端子28。用于集配电(pickingup and delivering electricity)到定子4的各相线圈29上的三个外部接线端子30从集配电环5沿径向向外延伸，而且通过用连接螺钉31将该外部连接端子30和前述母线6的连接部26一起连接到螺钉插入部32，可以将母线6和马达3的集配电环(electricity collection anddistribution ring)5连接起来。
三条母线6由如尼龙等绝缘性树脂材料制成的绝缘罩32覆盖。如图2和3所示，所述绝缘罩32由上下一对罩部件33、34构成，所述罩部件如此组合以便沿厚度方向夹住三条母线6。在这些罩部件33、34上设有容纳三条母线6的容纳部35和连接这些容纳部35的连接部36，在连接部36上设有以结合状态保持上下罩部件33、34的接合部37。
上述接合部37由接合孔38和接合突起39构成，所述接合孔设置在下侧罩部件34上，所述接合突起39设置在上侧罩部件33上并配合在前述接合孔38中，从而将两个罩部件33、34保持在固定到母线6上下的状态。另外，在下侧罩部件34上，在母线6以安装到集配电环5上的状态配置在下侧的部位处，设有沿厚度方向贯通的排水孔40。
另外，在构成前述绝缘罩32的一对罩部件33、34上，分别设有使长度方向的一部分沿厚度方向突出的突出部41、42。突出部41、42沿罩部件33、34的宽度方向上的整个长度设置，而且当安装绝缘罩32的母线6与集配电环5连接时，绝缘罩32的突出部41、42正好闭塞端子盒9的贯通孔13及马达壳体11的贯通孔12，并空出微小的间隙。
在构造根据该实施例的配线构造时，首先，在三条母线6分别配置在绝缘罩32的容纳部35中的状态下，组合构成绝缘罩32的上下一对罩部件33、34。由此，设置在上侧罩部件33上的接合突起39配合在设置在下侧罩部件34上的接合孔38中，从而母线6由绝缘罩32覆盖。此时，将设置在各母线6两端的连接部25、26保持在露出状态。而且，因此，三条母线6由绝缘罩32一体地保持。
接着，将如此一体化的三条母线6安装在连接端子8上，其中所述连接端子8安装在马达壳体11上。此时，将母线6从端子盒9插入贯通孔12，并将其固定到马达壳体11内部的连接端子28上。此时，通过用连接螺钉31将从固定在定子4上的集配电环5延伸的外部连接端子30和母线6一端侧的连接部26连接在一起，母线6被固定在马达3上，同时集配电环5和母线6电连接。
而后，如此设置母线6，以便其从马达壳体11内到设置在马达壳体11外的端子盒9内沿径向向外，并从马达3朝向传动装置2侧倾斜地延伸。
在这种状态下，专用罩17封闭端子盒9的开口部16地固定到内燃机1上，另外，将传动装置2固定到安装在内燃机1上的马达3上。如图1所示，虽然冷却用配管的连接接头43从内燃机1延伸到马达3的上方，但是由于端子盒9被配置在从马达3上方偏离的位置，以便位于传动装置2的上面，所以冷却用配管的连接接头43不会堵塞开口部16。
而后，通过设置在端子盒9侧壁15上的贯通孔19将电源电缆7插入端子盒9内，并通过将连接螺钉23结合到固定在端子盒9内的连接端子8的各螺钉插入孔22中，可以将安装在电缆末端的压接端子44和设置在前述罩6一端的连接部25连接起来。因此，电源电缆7通过母线6和集配电环5与定子4的各线圈29电连接。
因此，构造了根据该实施例的马达3的配线构造。
之后，通过用紧固螺钉18将罩17安装在打开的端子盒9的开口部16上，可以密封端子盒9，从而防止从外部进水等。
下面说明根据本实施例的马达3的配线构造的作用。根据该实施例的马达3的配线构造，由于端子盒9从马达3的上表面到向传动装置2的上面偏离的位置延伸，而且在该位置具有开口部16，所以即使在马达3安装到内燃机1上的状态中，也能防止从内燃机1延伸到马达3侧的辅机类，特别是冷却用配管的连接接头43覆盖开口部16。因此，即使在马达3安装在内燃机1上之后，也能在端子盒9内进行电源电缆7和母线6的连接操作。
即，在马达3安装在内燃机1上的状态下，由于能在端子盒9内操作连接螺钉23，而且能打开和关闭端子盒9的罩17，所以当将马达3安装到内燃机1上时，能操作处理马达3而不用连接重的电源电缆7，同时能进行端子盒9内的维修工作而不用将马达3从内燃机1上取下。
而且，根据该实施例，由于如上所述，连接端子盒9内的连接端子8和马达壳体11内部的集配电环5的母线6沿径向和轴向倾斜地设置，其中端子盒9设置在偏离到传动装置2上面的位置处，所以不会使母线6本身成为复杂的结构，从而能简单地制造。而且，由于三条母线6由绝缘罩32覆盖而一体化，所以能同时进行母线6的安装操作，从而能使配线操作的操作性提高。
另外，根据该实施例，由于代替现有技术使用绝缘涂膜进行的用于母线6的绝缘处理，母线6由绝缘性树脂材料制成的绝缘罩32覆盖，所以能减少绝缘处理所需的时间并降低产品成本。而且，在装配母线6的状态下，通过设置在绝缘性树脂材料制成的绝缘罩32上的突出部41、42闭塞母线6和端子盒9内表面之间的间隙，或者使其小到连接螺钉23不能通过的程度，所以如图5所示，能预先防止连接母线6和电源电缆7的连接螺钉23等元件从母线6和端子盒9内表面之间的间隙落到贯通孔12内。
另外，根据该实施例，在代替使用绝缘涂膜的绝缘处理，用绝缘罩32覆盖的情况下，考虑的是该绝缘罩32和母线6之间进水时绝缘性能降低，但是由于在该实施例中，在配置在绝缘罩32下侧的部分上设置排水孔40，所以进入绝缘罩32和母线6之间的水从排水孔40排出，从而能保持绝缘性能没有降低。
这样，根据该实施例的配线构造，能容易地进行装配操作和维修操作。
而且，通过由绝缘性树脂制成的绝缘罩32，能简单且以低成本确实地绝缘配置在集配电环5和电源电缆7之间的母线6，并能防止连接螺钉23等异物落入贯通孔12中。
在该实施例中，说明了端子盒9配置在传动装置2上部的情况，但是本发明不限定于此，不用说，将端子盒配置在传动装置2侧部等任意位置都是可以的。
另外，作为绝缘罩32的材料，举例说明了尼龙，但是代替该材料，可以使用任意的绝缘性树脂材料。
正如从以上的说明变得显然的，本发明具有下述效果。
根据技术方案1的发明的混合动力车辆用马达的配线构造，通过使端子盒从马达壳体外面延伸到传动装置侧，能避开与安装在内燃机上的辅机类等的干涉，从而能容易地进行针对端子盒的配线操作或维修操作。因此，装配操作简化，产品成本降低，而且可靠性提高，同时能达到维修操作简化和维持完整性的效果。
根据技术方案2的发明的混合动力车辆用马达的配线构造，不使导电部件露出到马达壳体的外部，而且不进行复杂的配线布置，就能容易地将端子盒配置在传动装置侧。
根据技术方案3的发明的混合动力车辆用马达的配线构造，即使端子盒被配置在和连接到内燃机上的冷却用配管重叠的位置，也能减少和冷却用配管的干涉，并能容易地进行端子盒内的连接操作。
根据技术方案4的发明的混合动力车辆用马达的配线构造，能简单且以低成本制造导电部件，而且即使对于进水也能实现稳定的绝缘性能。
根据技术方案5的发明的混合动力车辆用马达的配线构造，由于利用绝缘罩能防止异物从端子盒落入贯通孔，所以能预先防止因异物进入而引起的马达故障等的发生。
本发明提供了一种能使电源电缆的维修性提高并使产品成本降低的混合动力车辆用马达的配线构造，这种配线构造可以被用在混合动力车辆上。
