车辆用驱动装置
技术领域
本发明涉及使用发动机以及电动机对车辆的前、后轮进行驱动的车辆用驱动装置，尤其涉及搭载有串联式交流发电机的车辆用驱动装置。
背景技术
特开2001-333507号公报公开了以下的车辆用驱动装置，其具备由车辆的内燃机驱动且向车辆用电负载供给电力的第一发电机、和对所述车辆的前、后轮中的不由所述内燃机驱动的另一方车轮进行驱动的电动机，并且具备对由所述内燃机驱动且向所述电动机供给电力的第二发电机以及所述电动机进行控制的控制装置，所述控制装置包含所述第二发电机具有的控制装置以外的外部控制装置，从所述外部控制装置，作为所述第二发电机的控制指令而输出该第二发电机的励磁电流的开关信号，从而能任意设定该第二发电机的输出电压或者电流。
另一方面，在特开平11-098789号公报中公开了以下内容，即，使用串联式交流发电机，将第一直流电力供给给车载蓄电池以及车载电负载，将另一方的第二直流电力向高电压的EHC供给加热，从发动机启动开始到经过规定时间后，使用第一直流电力和第二直流电力双方向车载蓄电池以及车载电负载进行供给。
[专利文献1]特开2001-333507号公报
[专利文献2]特开平11-098789号公报
在上述的前者的技术中，具备由对车辆前轮进行驱动的内燃机驱动且向车辆用电负载供给电力的第一发电机、和同样地由所述内燃机驱动且向驱动后轮的电动机供给电力的专用的第二发电机，并且使用该第二发电机直接驱动车轮驱动用的电动机，但各自的发电机完全是由不同的机构构成。
尤其是，由于第二发电机依赖内燃机的旋转产生输出，因此在内燃机低速旋转时无法期望高电压化，作为驱动电动机用时还不够充分。
在上述的后者的技术中公开了以下内容，即，使用串联式交流发电机，将第一直流电力供给给车载蓄电池以及车载电负载，将另一方的第二直流电力向高电压的EHC供给加热，从发动机启动开始到经过规定时间后，使用第一直流电力和第二直流电力双方向车载蓄电池以及车载电负载进行供给，但是与前者一样，在内燃机低速旋转时无法期望高电压化。
发明内容
本发明的一个目的在于提供一种具备不受内燃机旋转状态的影响并能向驱动用电动机供给足够的电力的发电装置的车辆用驱动装置。
本发明的另一个目的在于提供一种具备如下的发电装置的车辆用驱动装置，该发电装置通过将低电压产生用发电机和高电压产生用发电机中的发热量低的哪一方作为散热体而提高冷却效率，防止由发热引起的输出降低，且能够向车载用蓄电池、驱动用电动机等供给充足的电力。

具体实施方式
图1是表示车辆用驱动装置的第一实施方式的车辆系统图，其中，作为四轮驱动车辆的车辆用驱动装置1的前轮2由发动机(内燃机)3驱动，且后轮4由直流电动机5驱动。所述发动机3由发动机控制单元(未图示)控制。所述发动机3的输出经由变速器7和传动轴8，传递驱动力给所述前轮2。
构成所述发动机3的发动机组(未图示)中设有向车载蓄电池9供给电力的第一发电机10A。该第一发电机10A借助发动机3并经由皮带等而进行旋转驱动，最终产生电力。
与所述第一发电机10A并列设置的第二发电机10B具有与所述第一发电机10A以一体形式被旋转驱动的关系，其输出比第一发电机10A大，并且经由继电器11供给给所述直流电动机5，其中，所述继电器11是由来自4WD控制单元6的输出控制信号控制。另一方面，当对动力传递进行开关操作的离合器12处于开状态时，该电动机5的动力经由差动齿轮13向传动轴14传递，驱动后轮4。
即，根据来自将车载蓄电池9作为电源而动作的4WD控制单元6的输出，离合器12被驱动(开)，直流电动机5的励磁线圈5F被励磁的同时继电器线圈11F也被励磁，使得继电器11被开通，而从第二发电机10B将被整流的直流成分供给给所述电动机5的电枢，从而驱动电动机5。
接着，参照图2，对发电装置10的电路结构进行说明。本发电装置10是所谓的串联式发电机，其具有以下结构，即，第一发电机10A将来自以△方式接线的发电线圈15的输出，经由全波整流器16供给给作为低电压电源(通常10～16V)的车载蓄电池9。
另一方面，励磁线圈15F与所述车载蓄电池9接线，构成初始励磁电路，用由来自所述4WD控制单元6的输出信号进行驱动的调节器17控制电力。并列设置的另外的第二发电机10B将输出电压设定为第一发电机的大致3倍(42V)，并且分别具备与所述第一发电机相同地以△方式接线的发电线圈18、全波整流器19、由车载蓄电池9被初始励磁的励磁线圈18F、以及由来自4WD控制单元6的输出信号进行控制的调节器20。
在起动发动机3时，由来自4WD控制单元6的输出信号，向第一发电机10A以及第二发电机的调节器17、20分别供给来自车载蓄电池9的励磁电流，并由所谓他励磁开动发电机。如果发动机3起动且发电装置10由发动机3的作用进行旋转驱动，则各个发电机10A、10B从所述他励磁切换到自励磁并继续发电。
图7表示了所述第二发电机10B的输出特性的一例。第二发电机10B的励磁电流将蓄电池和第二发电机自身的双方作为电流供给源，并在车辆起步时即在第二发电机10B起动时或者低速旋转时，成为基于车载蓄电池9的电力的他励磁，进而如图显示的那样表示出左下降的输出特性。另外，车辆起步后行驶时，切换到将第二发电机10B的自身输出作为电流供给源的自励磁方式，第二发电机10B的输出与发动机转速成比例产生，并且发电机的输出范围在端子电压、电流一同地在抛物线上放大。另一方面，如果去除配线电阻部分，可以将输出电压V视为直流电动机5的输入电压。从而，通过控制第二发电机10B的励磁电流，可以将向电动机5的输出电压切换成多级别，或者在规定区域中能够连续进行切换，从而能够对车辆所要求的驱动力进行自由响应。
在图3中，是在本发明使用的发电装置100，其将伦德尔转子21、22压入固定在旋转轴23上，且在各个转子上经由绝缘线轴安装有圆筒状的励磁线圈21F、22F。而且，将所述一对转子21、22相互密接配置，在其一端通过焊接等固定离心风扇24，并保持所述励磁线圈21F、22F的引线端。
另一方面，在各个转子21、22上夹隔旋转空隙配置的各个定子铁心25、26固定在形成为筒状的托架27的内周面，并卷取有发电线圈25A、26A。所述旋转轴23通过轴承保持在所述托架27的侧面27A、和以盖住外部托架27的开口端的方式配置的尾架28上。
另外，滑环装置29由以下部分构成，即，由固定在旋转轴23上，并与所述励磁线圈21A、22A的引线端电连接，且相互之间电绝缘的滑环29A、29B、29C，以及，将一端固定在所述尾架28的外侧面，并对与所述滑环29A、29B、29C滑动连接的各个电刷(-)29a、电刷(+)29b、29c进行保持的电刷架构成。该滑环装置29被由尾架28保持的防尘盖30覆盖，在该防尘盖的内周空间中借助适当机构配置固定有所述电压调整用调节器17、20。
根据本发明，通过简单电路构成，使用与第一发电机并列设置的第二发电机的输出，对后轮驱动用的电动机的驱动力进行调整，从而获得足够的驱动力。因此，可以在从车辆起步时到高速爬坡运转为止的广的运转范围内，确保不逊于所谓机械式4WD的驱动力性能，且能够将发电装置本身形成为简单结构，并使其操作性极其优良。
此外，发电机本身将两组转子安装在同一旋转轴上，其两者间的侧面密接(对接)固定。而且通过仅将一方的侧面形成为固定风扇的构造，可以获得能够将反风扇侧的转子作为散热体作用、小型且可有效冷却的发电装置。
(实施例1)
图4表示车辆用驱动装置的第二实施方式，而图5表示了在电动机驱动电路上设置高压辅助蓄电池并形成简易混合设置时的电路接线状况。
即，在第二发电机10B和交流电动机51之间串联设置继电器111，具体地说具有以下构成，即，在设置串联连接的第一继电器11A和第二继电器11B的同时，在该两个继电器11A、11B之间设置第三继电器11C，并经由该继电器11C以及电流限制装置30，向辅助蓄电池31供给电流。
这些动作概要如表1所示，即，(1)利用驱动电动机5行驶的EV行驶、(2)当是带有旋转检测机构的串联式发电机(发电装置10)的情况下，用辅助蓄电池31的电力或者由蓄电池31驱动串联式发电机(发电装置10)，进而使发动机起动、(3)从串联式发电机(发电装置10)向电动机5直接供给电力并用发动机3和所述电动机进行驱动行驶的4WD行驶、(4)从串联式发电机(发电装置10)向辅助蓄电池充电、(5)从驱动电动机5的充电等。根据这些各个状态，产生来自4WD控制器6的指令，使各继电器动作以满足指令要求。

作为简易混合设置，如果在后轮驱动中使用如同步电动机等交流发电机，则可以高电力驱动而有效，但必须具备对再生制动时的发电能量进行回收的装置，作为辅助电源使用的辅助蓄电池成为有效的措施。
(实施例2)
图6是表示将发电装置作为马达发电机(motor generator)使用的情况的构成的图，所以虽然基本构成与图3相同，但由于旋转检测机构是必须的，因此延长转子的滑环装置29侧旋转轴23并在其前端部安装解算装置的转子40，与定子41一同配置在所述的电压调整用调节器17、20的内周侧空间。该结构由于能有效利用死空间，因此能够提供紧凑化的马达发电机。
