Description
技术领域
本发明涉及作为驱动源具有发动机和电机的混合动力车辆的驱动装置,具体就是一种在带有闭锁离合器的流体传动装置内具备发动机动力中断离合器的车辆用驱动装置。
背景技术
作为搭载于混合动力车辆中的驱动装置,广泛地采用将驱动源所产生的旋转借助带有闭锁离合器的流体传动装置向变速机构传递的驱动装置。此外,在这种驱动装置中,具备相对于流体传动装置传递或中断发动机的驱动力的发动机动力中断离合器。这里,闭锁离合器是用于将动力源所产生的驱动力不经由流体而向变速机构传递的构件,一旦车速到达预先设定好的速度即进行作动(闭锁),通过消除传递损耗来改善油耗。
作为此种具备带有闭锁离合器的流体传动装置的驱动装置之一,有将发动机动力中断离合器配置于带有闭锁离合器的流体传动装置内的驱动装置(专利文献1)。在该驱动装置中,通过向设于流体传动装置的壳体与两个离合器的活塞之间的各腔室分别供应油压,在各腔室间产生压力差,从而使发动机动力中断离合器及闭锁离合器分别作动。
专利文献1:日本特开2000-110916号公报
但是,在上述的驱动装置中,由于利用向各腔室供应的油压的压力差,来控制发动机动力中断离合器和闭锁离合器的动作,因此存在其控制性差的问题。另外,由于发动机动力中断离合器及闭锁离合器是单片式的离合器,因此还有传递扭距容量比较小的问题。此外,由于摩擦材料面积小,因此还有离合器卡合时的摩擦材料的放热量变高的问题。
这里,为了提高发动机动力中断离合器与闭锁离合器的控制性及传递扭距容量,考虑将发动机动力中断离合器及闭锁离合器从上述的单片式的离合器置换为具备油压促动器的多片式的离合器。但是,如果只是简单地将两个离合器从单片式的置换为多片式的话,则会产生流体驱动装置大型化这样的新问题。
发明内容
于是,本发明是为了解决上述的问题而完成的,其目的在于提供一种车辆用驱动装置,是将发动机动力中断离合器配置于带有闭锁离合器的流体传动装置内的驱动装置,可以提高两个离合器的控制性和传递扭距容量,并且减少离合器卡合时的摩擦材料的放热量,同时抑制流体驱动装置的大型化,进而抑制驱动装置的大型化。
为了解决上述问题而完成的本发明的一个方式,是如下的车辆用驱动装置,具有:变速机构、被配设于比上述变速机构靠近发动机安装侧,并具备闭锁离合器的流体传动装置、具备转子及定子,并将上述转子与上述流体传动装置的输入部连结的电动机、相对于上述流体传动装置传递或中断发动机的驱动力的发动机动力中断离合器,其特征在于,上述闭锁离合器具备:多个摩擦片、推压上述摩擦片的油压促动器,上述闭锁离合器在上述流体传动装置内配置于比循环腔(torus)靠近发动机安装侧,并且上述摩擦片配置于上述循环腔的外径部与上述流体传动装置的前罩之间,上述发动机动力中断离合器具备:多个摩擦片、推压上述摩擦片的油压促动器,上述发动机动力中断离合器在上述流体传动装置内配置于比上述循环腔靠近发动机安装侧,并且被以比上述闭锁离合器的外径小的直径构成,上述电动机在上述发动机动力中断离合器的外径侧,被与上述发动机动力中断离合器用摩擦片在轴向上重叠配置。
在该车辆用驱动装置中,闭锁离合器和发动机动力中断离合器分别由多片式的离合器构成,各离合器的摩擦片由各自的油压促动器推压。所以,可以分别独立地控制闭锁离合器和发动机动力中断离合器,并且可以增大传递扭距容量,另外,可以减少离合器卡合时的摩擦材料的放热量。这样,就可以提高发动机动力中断离合器及闭锁离合器的控制性及传递扭距容量,并且减少放热量。
此外,在该车辆用驱动装置中,闭锁离合器用摩擦片配置于循环腔外径侧。这样,就可以使闭锁离合器与循环腔邻近地配置。另外,通过使发动机动力中断离合器的直径比闭锁离合器小,就可以在确保比发动机动力中断离合器要求更大的传递扭距容量的闭锁离合器的必需容量的同时,将两个离合器在轴向上邻近地配置。所以,由于即使在带有闭锁离合器的流体传动装置内设置发动机动力中断离合器,也可以将配置于流体传动装置内的构件在轴向上邻近地配置,因此可以抑制流体传动装置在轴向上的大型化。其结果是,还可以抑制驱动装置的大型化。
此外,在该车辆用驱动装置中,在发动机动力中断离合器的外径侧,与发动机动力中断离合器用摩擦片在轴向上重叠配置有电动机。由此,由于可以将流体传动装置与电动机在轴向上邻近地配置,因此可以更为可靠地抑制驱动装置在轴向上的大型化。
这样,根据该车辆用驱动装置,在带有闭锁离合器的流体传动装置中配置发动机动力中断离合器,可以提高发动机动力中断离合器与闭锁离合器的控制性及传递扭距容量,并且减少离合器卡合时的摩擦材料的放热量,同时抑制流体传动装置的大型化,进而抑制驱动装置的大型化。
在上述的车辆用驱动装置中,最好具有保持上述闭锁离合器用摩擦片的闭锁离合器用离合器鼓,上述闭锁离合器用离合器鼓在上述循环腔的外径侧,被与上述循环腔的一部分在轴向上重叠配置。
通过设为这样的构成,就可以有效地利用循环腔外径侧的空间,因此可以抑制流体传动装置在轴向上的大型化。其结果是,可以抑制驱动装置的大型化。
另外,在上述的车辆用驱动装置中,最好上述闭锁离合器用离合器鼓具备在上述循环腔的外径侧与涡轮的外廓连结的连结构件。
通过设为这样的构成,将闭锁离合器用离合器鼓与涡轮连结时,就可以有效地利用循环腔外径侧的空间,其结果是,可以将闭锁离合器与循环腔在轴向上更加邻近地配置。所以,可以进一步抑制流体传动装置在轴向上的大型化,可以更为可靠地抑制驱动装置的大型化。
另外,在上述的车辆用驱动装置中,最好上述闭锁离合器用促动器及上述发动机动力中断离合器用促动器分别具备:推压上述各摩擦片的活塞、供应用于使上述活塞作动而使离合器卡合的卡合压力的液密状的卡合压室,上述闭锁离合器用促动器和上述发动机动力中断离合器用促动器中的至少一方被配置为:上述活塞的一部分与上述卡合压室在上述摩擦片的内径侧在轴向上重叠。
通过在闭锁离合器用促动器和发动机动力中断离合器用促动器中的至少一方中,将活塞的一部分与卡合压室在摩擦片的内径侧在轴向上重叠配置,就可以有效地利用摩擦片的内径侧的空间来构成油压促动器。所以,就可以抑制离合器的轴向尺寸的大型化,其结果是,可以抑制流体传动装置在轴向上的大型化。
另外,在上述的车辆用驱动装置中,最好上述发动机动力中断离合器用促动器的卡合压室由上述发动机动力中断离合器用活塞和上述前罩形成。
通过设为这样的构成,就不需要为了形成发动机动力中断离合器用促动器的卡合压室而设置专用的构件。由此,因不需要专用的构件而可以缩短发动机动力中断离合器的轴向尺寸。所以,可以抑制伴随着将发动机动力中断离合器配置于流体传动装置内而产生的轴向尺寸的大型化。另外,由于不需要专用的构件,因此构成部件数得到削减,从而还可以实现低成本化及轻质化。
另外,在上述的车辆用驱动装置中,最好上述闭锁离合器用促动器的卡合压室由上述闭锁离合器用活塞和涡轮机毂形成。
通过设为这样的构成,就不需要为了形成闭锁离合器用促动器的卡合压室而设置专用的构件。由此,因不需要专用的构件而可以缩短闭锁离合器的轴向尺寸。所以,可以抑制伴随着将发动机动力中断离合器配置于流体传动装置内而产生的轴向尺寸的大型化。另外,由于不需要专用的构件,因此构成部件数得到削减,从而还可以实现低成本化及轻质化。
另外,在上述的车辆用驱动装置中,最好上述闭锁离合器用摩擦片与上述发动机动力中断离合器用摩擦片在轴向上重叠配置。
通过设为这样的构成,就可以在流体传动装置内将闭锁离合器与发动机动力中断离合器在轴向上邻近地配置。所以,可以抑制伴随着将发动机动力中断离合器配置于流体传动装置内而产生的轴向尺寸的大型化。
另外,在上述的车辆用驱动装置中,最好闭锁离合器用离合毂由上述发动机动力中断离合器用离合器鼓构成。
通过像这样将闭锁离合器用离合毂和发动机动力中断离合器用离合器鼓用一个构件来构成,就可以将两个离合器的摩擦片小型化。所以,可以抑制伴随着将发动机动力中断离合器配置于流体传动装置内而产生的大型化。另外,由于离合器的构成部件数得到削减,因此还可以实现低成本化及轻质化。
根据本发明的车辆用驱动装置,如上所述,在将发动机动力中断离合器配置于带有闭锁离合器的流体传动装置内的驱动装置中,可以在提高两个离合器的控制性和传递扭距容量,并且减少离合器卡合时的摩擦材料的放热量的同时,抑制流体驱动装置的大型化,进而抑制驱动装置的大型化。

具体实施方式
下面,基于附图对将本发明的车辆用驱动装置具体化了的优选实施方式进行详细说明。在本实施方式中,针对单电机的平行型的混合动力车辆的驱动装置进行说明。所以,在参照图1及图2的同时,针对实施方式的驱动装置进行说明。图1是表示实施方式的驱动装置的概略构成的局部剖面图。图2是实施方式的驱动装置内的变矩器附近的放大剖面图。
如图1所示,驱动装置10具备:收纳于变速器体18中的多级变速机构11、具有闭锁离合器的变矩器13、由无刷DC电机等构成并收容于电机壳体19中的电机-发电机14。此外,驱动装置10在图1左侧部分(发动机安装侧)与汽油发动机等内燃机15连接。
该驱动装置10将其构成部件以单轴状配置,并适用前置发动机-后轮驱动(FR)方式。具体来说,从发动机安装侧开始,在同一轴上顺次配置电机-发电机14、变矩器13以及变速机构11,将输入轴16的旋转用变速机构11变速而向输出轴17输出。
如图2所示,变矩器13具有涡轮20、泵轮21以及定子22,涡轮20与涡轮机毂23连结,上述涡轮机毂23被花键联接在输入轴16上。另外,在变矩器13与变速机构11之间配设有机油泵25,泵壳25a固定于变速器体18上。
固定于泵轮21的基部的轮毂24,在泵壳25a的内周被借助滚针轴承自由旋转地支承,并且在泵壳25a与轮毂24之间配设有油封。另外,定子22与单向离合器28连结,单向离合器28的内部轴承保持架,借助被配置于输入轴16与轮毂24之间的套筒29固定于机油泵25上。
此外,固定于泵轮21上的前罩30的外径部分30a将闭锁离合器40覆盖地沿轴向向发动机侧(前方)延伸,中间部分30b将发动机动力中断离合器50覆盖地倾斜构成,其内径部分30c在半径方向上大致垂直地延伸。在该前罩30的内径端,形成有轮毂部30d,在轮毂部30d内游插有中心件31。这样,前罩30与中心件31就可以相对旋转。另一方面,在轮毂部30d的外周,花键联接后述的转子毂66。
中心件31与输入轴16中心对准地朝向前方(发动机15侧)沿轴向延伸,其后端部分为空心,在该空心部分中配置有输入轴16的末端部。这样,中心件31与输入轴16就可以相对旋转。另一方面,在中心件31的末端部分,连结着减震机构32的内径侧。该减震机构32被固定于与发动机15的曲轴15a连结的驱动盘33上。这样,发动机15的驱动力就会经由减震机构32向中心件31传递。利用该减震机构32,将来自发动机15的扭曲振动吸收,不将其向中心件31传递。
收纳、配置于前罩30的沿轴向延伸的外径部分30a的内径侧的闭锁离合器40,被与涡轮20相邻地配置,是具备多个摩擦片41、推压摩擦片41的促动器45的多片式离合器。这样,就可以提高闭锁离合器40的扭距传递容量及控制性,并且减少离合器卡合时的放热量。这里,摩擦片41由离合器片41d和离合器盘41p构成,位于涡轮20(循环腔35)的外径侧。这样,就可以使闭锁离合器40的直径比较大,可以确保必需的足够的扭距传递容量。而且,在本实施方式中,设有2片离合器片41d。
此外,离合器片41d与轮毂42的花键卡合,而离合器盘41p与离合器鼓43的花键卡合。促动器45由与摩擦片41抵接、分离的活塞盘46、供应使活塞盘46移动的油压(离合器卡合压力)的油压室47、用于将活塞盘46送回(松开离合器)的回位弹簧48构成。这样,由于闭锁离合器40具有独立的促动器45,因此与以往的利用压差来作动的离合器相比控制性提高。
离合器片41d所卡合的轮毂42,也是发动机动力中断离合器50的离合器鼓53的一部分。也就是说,闭锁离合器40的轮毂42由发动机动力中断离合器50的离合器鼓53构成。也就是说,闭锁离合器40的轮毂42与发动机动力中断离合器50的离合器鼓53被共用而以一个部件构成。这样,就可以实现部件数目的削减,并且可以实现两个离合器40、50的小型化。
另一方面,离合器盘41p所卡合的离合器鼓43,具有沿轴向延伸而与涡轮20的外廓连结的连结部43a。利用该连结部43a,将离合器鼓43连结、固定在涡轮20上。这样,由于可以有效地利用由涡轮20及泵轮21的外廓构成的循环腔35的外径侧空间,因此可以将闭锁离合器40与循环腔35在轴向上邻近地配置。
此外,对摩擦片41的前方侧由与离合器鼓43卡合的卡环44进行防脱。另一方面,后方侧被设为与活塞盘46抵接。这样,通过使活塞盘46移动,就可以将闭锁离合器40连接或分离。
活塞盘46被制成与离合器鼓43和涡轮机毂23密合地自由移动。这里,活塞盘46的内径侧端部夹隔着油封49a与涡轮机毂23的轮毂部23a的外周面密合。另外,在活塞盘46的径向大致中央处,形成有以コ字形弯曲的向前方侧突出的弯曲部46a。此外,在弯曲部46a的后方侧凹部外周面,夹隔着油封49b密合着在涡轮机毂23的外周端部向前方侧延伸设置的延设部23b。利用这样的构成,由活塞盘46和涡轮机毂23形成液密状的油压室47。所以,由于不需要用于形成油压室47的专用构件,因此可以缩短闭锁离合器40的轴向尺寸,并且可以削减构成部件数目。
如上所述地形成的油压室47,与活塞盘46的一部分在轴向上重叠。这样,就可以有效地利用摩擦片41的内径侧空间来构成促动器45,可以实现闭锁离合器40在轴向上的小型化。
另外,收纳、配置于前罩30的中间部分30b的内径侧的发动机动力中断离合器50,被以比闭锁离合器40小的直径构成,并且相对于闭锁离合器40配置于发动机15侧。此外,发动机动力中断离合器50也与闭锁离合器40相同,是具备多个摩擦片51、推压摩擦片51的促动器55的多片式离合器。这样,就可以提高发动机动力中断离合器50的扭距传递容量及控制性,并且减少离合器卡合时的放热量。这里,摩擦片51由离合器片51d和离合器盘51p构成,本实施方式中设有2片离合器片51d。
这样,通过使发动机动力中断离合器50的直径比闭锁离合器40小,就可以在确保比发动机动力中断离合器50要求更大的传递扭距容量的闭锁离合器40的必需容量的同时,将两个离合器40、50在轴向上邻近地配置。
此外,离合器片51d与轮毂52的花键卡合,而离合器盘51p与离合器鼓53的花键卡合。促动器55由与摩擦片51抵接、分离的活塞盘56、被供应使活塞盘56移动的油压(离合器卡合压力)的油压室57、用于将活塞盘56送回(松开离合器)的回位弹簧58构成。
另外,离合器片51d所卡合的轮毂52的内径侧被固定于中心件31的后端部外周。这样,轮毂52就会与中心件31一起旋转。另一方面,离合器盘51p所卡合的离合器鼓53被固定于前罩30的内径部分30c,其相反一侧端部如前所述被作为闭锁离合器40的离合器鼓43构成。
此外,针对摩擦片51的后方侧由与离合器鼓53卡合的卡环54进行防脱。另一方面,前方侧被设为与活塞盘56抵接。这样,通过使活塞盘56移动,就可以将发动机动力中断离合器50连接或分离。
活塞盘56被制成与离合器鼓53和前罩30密合地自由移动。这里,活塞盘56的内径侧端部夹隔着油封59a与前罩30的轮毂部30d的外周面密合。另外,在活塞盘56的径向大致中央处,形成有以コ字形弯曲的向前方侧突出的弯曲部56a。此外,在弯曲部56a的前方侧凹部外周面,夹隔着油封59b密合着在前罩30的内径部分30c向后方侧延伸设置的延设部30e。利用这样的构成,由活塞盘56和前罩30形成液密状的油压室57。所以,由于不需要用于形成油压室57的专用构件,因此可以缩短发动机动力中断离合器50的轴向尺寸,并且可以削减构成部件数目。
如上所述地形成的油压室57与活塞盘56的一部分在轴向上重叠。这样,就可以有效地利用摩擦片51的内径侧空间来构成促动器55,可以实现发动机动力中断离合器50在轴向上的小型化。
此外,如上所述地构成的闭锁离合器40与发动机动力中断离合器50被配置为,各自的摩擦片41、51的一部分在轴向上重叠。可以实现此种配置,这是因为,以比闭锁离合器40更小的直径构成发动机动力中断离合器50。利用这样的两个离合器40、50的配置,就可以将两个离合器40、50在轴向上邻近地配置。
这样,由于可以将缩短了轴向尺寸的闭锁离合器40和发动机动力中断离合器50邻近地配置,并且可以将闭锁离合器40与循环腔35邻近地配置,因此即使在具备闭锁离合器40的变矩器13内设置发动机动力中断离合器50,也可以抑制变矩器13的大型化。
此外,电机-发电机14具有定子61和转子62,这些定子61与转子62在前罩30的外径部分30a的一部分及中间部分30b的外径侧,被配置于大致对齐排列的位置,即,配置于与位于其内径侧的发动机动力中断离合器50在轴向上重叠的位置。由此,由于可以将变矩器13与电机-发电机14在轴向上邻近地配置,因此可以可靠地抑制驱动装置10在轴向上的大型化。
这里,定子61是在由沿轴向层叠的层叠钢板构成的定子芯61a上卷绕线圈61b而成的,固定于电机壳体19上。转子62是将由永久磁铁构成的多个层叠板62a沿轴向排列而构成的,这些层叠板62a由支承板63固定、支承。
该支承板63具有在前罩30的内径部分30c的前方(发动机15侧)并且平行地沿半径方向延伸的圆板部63a、保持层叠板62a的保持部63b。保持部63b在轴向大致中央处与圆板部63a连结,沿轴向延伸。此外,转子62与定子61使其层叠板62a和定子芯61a在轴向上为相同的位置(重叠的位置),即,在规定的轴向长度处沿半径方向对齐排列,并且这些层叠板62a与定子芯61a留有微小的间隔地相面对。
另外,电机壳体19沿着定子61的前方部分地具有侧壁19a,在侧壁19a的中间部分与转子支承板63之间,设有分解器64。分解器64是用于正确地检测出转子62的旋转位置,控制流向定子61的电流的时机的装置,由分别以被精密加工了的层叠板制成的旋转体64a和固定体64b构成。此外,将由线圈激磁的固定体64b设于外径侧,将旋转体64a设于内径侧,沿半径方向对齐排列地(在轴向重叠的位置)配置。
此外,在电机壳体侧壁19a的内径端安装有滚珠轴承65。该滚珠轴承65配置于分解器64的内径侧且沿半径方向大致对齐排列的位置(在轴向上重叠的位置)。在滚珠轴承65的内径侧,以基本上没有间隙的精度高的公差状态(并非压入)嵌合着固定于转子支承板63的内径端的转子毂66。此外,轮毂66的内径侧被与前罩30的轮毂部30d花键联接。
接下来,针对上述的驱动装置10的动作进行说明。在车辆的停止状态下,并且在点火开关为ON状态下,如果驾驶者基于起步意图踩下加速踏板(低节气门开度时),则首先会向电机、发电机14流入来自电池(未图示)的电流,作为电机发挥作用。由无刷DC电机构成的电机-发电机14利用分解器64正确地检测出转子62的位置,基于此利用控制器(未图示)调整流向定子61的线圈61b的电流的时机,沿前进方向并且以高效率旋转转子62。该转子62的旋转经由转子支承板63、转子毂66,继而是前罩30、由泵轮21、涡轮20、以及定子22构成的变矩器13,伴随着规定的扭距比的增大向输入轴16传递。
此后,刚刚起步后的车辆处于比较低速的规定速度,如果将节气门踩到一定开度以上,则会使燃料喷射装置作动,利用火花塞点火,电机-发电机14作为起动电机发挥作用,将内燃机15起动。这样,内燃机15的曲轴15a的旋转就经由驱动盘33、减震机构32向中心件31传递。此后,将发动机动力中断离合器50连接,内燃机15的驱动力及作为电机发挥作用的电机-发电机14的驱动力被相加,向变矩器13传递,继而由变速机构11变速,以所需的转速向驱动车轮传递。这样,在车辆的加速状态或爬坡状态等需要大的驱动力的情况下,在内燃机15的驱动力上附加电机-发电机14的驱动力,以高马力使车辆行驶。
这里,由于发动机动力中断离合器50,是作为具有独立的促动器55的多片离合器构成的,因此相对于发动机扭距来说具有足够的扭距传递容量,并且可以减少离合器卡合时的放热量,而且控制性也很优异。由此,可以将内燃机15的驱动力可靠地向输入轴16传递,还可以减少放热量。
此外,如果车辆处于恒定高速行驶状态,则电机-发电机14被设为无负载运转(按照将由在电机中产生的反电动势产生的扭距抵消的方式控制电机输出),使电机-发电机14空转,单独以内燃机15的驱动力使车辆行驶。而且,根据电池的充电量(SOC),使电机-发电机14作为发电机发挥作用而进行能量的再生。在处于内燃机15的驱动状态或对内燃机15附加上电机的驱动状态(根据情况有仅利用电机的驱动状态)下,将闭锁离合器40连接。这样,向前罩30传递的扭距就经由轮毂42(离合器鼓53)、摩擦片41、离合器鼓43、涡轮20及涡轮机毂23,不用借助变矩器的油流地直接向输入轴16传递。
此时,如上所述,由于闭锁离合器40具有与循环腔35外径同等的直径,被作为具有独立的促动器45的多片离合器构成,因此即使是针对由上述电机辅助带来的高马力也具备足够的扭距容量,控制性也很优异。由此,就可以将内燃机15及电机14的驱动力可靠地向输入轴16传递。
另外,在因恒定低、中速行驶及下坡路行驶等而在内燃机15的输出中存在富余的情况下,与电池的SOC对应地,使电机-发电机14作为发电机发挥作用而将电池充电。特别是,在下坡时要求发动机制动的情况下,可以增大成为发电机的电机-发电机14的再生电力,获得足够的发动机制动效果。另外,在驾驶者踩下制动器而要求停止车辆的情况下,进一步增大电机-发电机14的再生电力,作为再生制动器作动,将车辆的惯性能量作为电力再生,减少由摩擦制动器所致的热造成的能量散逸。另外,在中速区中,为了可以在更高输出、更高效率的区域中运转内燃机15,也是将电机-发电机14设为再生状态,这样就可以提高发动机效率,并且可以基于利用再生对电池的充电来增大电机行驶,可以提高能量效率。
此外,在车辆因信号等停止的状态下,电机-发电机14被停止,并且燃料喷射装置变为OFF,内燃机15也被停止。即,没有以往的发动机的怠速状态。另外,从该停止状态开始的车辆的起步如前所述,首先是利用电机-发电机14的电机驱动力来起步,在其后不久的比较低速的状态下,通过利用电机驱动力将内燃机15起动,利用电机14的驱动力来辅助,而消除内燃机15的急剧的驱动力变动,顺畅地运转,此外在需要发动机制动时以及控制停止时,将电机-发电机14作为再生制动器而将车辆惯性能量作为电能再生。另外,在像发动机低负载、极低负载时那样发动机效率差的区域中进行电机行驶。通过将它们相结合,搭载本驱动装置10的混合动力车辆就可以实现油耗节省及废气的减少。
如上详细说明所示,根据本实施方式的驱动装置10,将闭锁离合器40及发动机动力中断离合器50分别设为具备促动器45、55的多片式的离合器。由此,可以提高闭锁离合器40及发动机动力中断离合器50的控制性及传递扭距容量,并且可以减少离合器卡合时的放热量。此外,将闭锁离合器40的摩擦片41配置于循环腔35的外径侧,并且将发动机动力中断离合器50以比闭锁离合器小的直径构成,将发动机动力中断离合器50设于变矩器13内。由此,就可以将闭锁离合器40与循环腔35在轴向上邻近地配置,并且可以将闭锁离合器40与发动机动力中断离合器50在轴向上邻近地配置。这样,由于可以将变矩器13内的构成部件在轴向上邻近地配置,因此可以抑制伴随着将发动机动力中断离合器50设于变矩器13内产生的变矩器13的大型化。
另外,在驱动装置10中,在发动机动力中断离合器50的外径侧,将电机-发电机14与发动机动力中断离合器50的摩擦片51在轴向上重叠地配置。由此,由于可以将变矩器13与电机-发电机14在轴向上邻近地配置,因此可以可靠地抑制驱动装置10在轴向上的大型化。
而且,上述的实施方式只不过是单纯的例示而已,并不对本发明做任何限定,当然可以在不脱离其主旨的范围内进行各种改良、变形。例如,上述的实施方式中,例示出将减震机构32配置于变矩器13外的情况,具体来说,例示出将本发明应用于配置在内燃机15与变矩器13之间的驱动装置的情况,然而本发明也可以如图3所示,将减震机构32a配置于变矩器13内,具体来说,也可以应用于配置在闭锁离合器40与发动机动力中断离合器50之间的驱动装置10a。像这样,通过将减震机构配置于变矩器13内,就可以提高减震机构的耐久性。
另外,在上述的实施方式中,将本发明应用于F·R型的驱动装置,然而并不限定于此,也可以应用于F·F(前置发动机-前轮驱动)型等其他的形式的驱动装置。此外,上述的实施方式作为电机-发电机使用无刷DC电机,然而也可以是直流电机、感应式交流电机等其他的电机。此外,上述的实施方式作为流体传动装置使用变矩器,然而也可以是液力偶合器等。
