动力传递装置
技术领域
本发明涉及一种使用内燃机和电动机的动力行驶的车辆所使用的动力传递装置。
背景技术
以往，公知一种具有湿式起步离合器、使用内燃机和电动机的动力行驶的车辆所使用的动力传递装置(例如，参照日本特开2010－516558号公报)。
发明内容
在将仅以内燃机作为原动机行驶的带变矩器的变速器改良为混合动力用的变速器的情况下，想到了配置电动机来替代变矩器。由此，不需要变更已有的变速器，就能够作为混合动力用的变速器使用。
另外，混合动力车辆当在利用电动机行驶过程中需要起动内燃机时，使内燃机起动。此处，混合动力车辆的行驶速度过低的话，有时电动机的旋转速度没达到能够使内燃机起动的可起动转速。
该情况下，需要通过使电动机的转速上升到可起动转速，并且调整变速器内的摩擦离合器等的压紧力，来调节传递量，以使传递到驱动轮的驱动力不会过大。但是，以往的调整变速器内的传递量的调整部并不是以调节起步所需的驱动力的传递量为目的制造的，因此，需要使调节部大容量化，需要大幅度地改变以往的变速器。
此外，虽然也考虑将电动机的转子连接到内燃机侧，经由起步离合器连接电动机和变速器，但是，这样的话，在仅利用电动机行驶的情况下，会总是会带动内燃机，仅利用电动机行驶时的效率会降低。
本发明鉴于上述问题点，目的在于提供一种在仅依靠电动机行驶时不会降低效率、能够直接利用以往的变速器的动力传递装置。
[1]为了达成上述目的，本发明的动力传递装置具有：
离合器输入部，来自内燃机的驱动力被传递至该离合器输入部；
离合器输出部，其与变速器连接；
起步离合器，其能够连接所述离合器输入部和所述离合器输出部；以及
电动机，其具有转子，
所述动力传递装置的特征在于，
所述离合器输入部、所述离合器输出部和所述起步离合器配置在所述转子内，
所述动力传递装置具有切换机构，该切换机构能够切换到连接所述转子和所述离合器输出部的输出侧连接状态以及连接所述转子和所述离合器输入部的输入侧连接状态。
根据本发明的动力传递装置，仅依靠电动机行驶时不会使效率降低，能够直接利用以往的变速器。
[2]此外，在本发明中，可以是，切换机构具有：在轴向上移动自如的滑块；使所述滑块移动的致动器；配置在所述转子的径向内侧且所述内燃机侧的内燃机侧滚珠；以及配置在所述转子的径向内侧且所述变速器侧的变速器侧滚珠，在所述离合器输出部上设置有能够收容所述变速器侧滚珠的输出侧收容孔，在所述离合器输入部上设置有能够收容所述内燃机侧滚珠的输入侧收容孔，在所述滑块位于所述变速器侧时，所述切换机构使所述变速器侧滚珠与所述输出侧收容孔卡合，成为使所述转子与所述离合器输出部接合的所述输出侧连接状态，在所述滑块位于所述内燃机侧时，所述切换机构使所述内燃机侧滚珠与所述输入侧收容孔卡合，成为使所述转子与所述离合器输入部接合的所述输入侧连接状态。
[3]此外，在本发明中，优选的是，所述输入侧收容孔形成为比所述内燃机侧滚珠的半径浅，所述输出侧收容孔形成为比所述变速器侧滚珠的半径浅。
[4]此外，在本发明中，可以是，所述转子设置有磁铁，所述磁铁维持使所述内燃机侧滚珠和所述变速器侧滚珠从所述输入侧收容孔和所述输出侧收容孔中脱出的状态。
[5]此外，在本发明中，可以是，所述切换机构具有在轴向上移动自如的圆筒状的滑块和使所述滑块移动的致动器，在所述滑块的内周面上设置有位于所述变速器侧的变速器侧内齿和位于所述内燃机侧的内燃机侧内齿，在所述离合器输出部上设置有能够与所述变速器侧内齿啮合的输出侧外齿，在所述离合器输入部上设置有能够与所述内燃机侧内齿啮合的输入侧外齿，在所述滑块位于所述变速器侧时，所述切换机构使所述变速器侧内齿与输出侧外齿卡合，使所述转子和所述离合器输出部接合，在所述滑块位于所述内燃机侧时，所述切换机构使所述内燃机侧内齿与所述输入侧外齿卡合，使所述转子和所述离合器输入部接合。
[6]此外，在本发明中，可以是，除了所述输出侧连接状态和所述输入侧连接状态以外，所述切换机构还能够切换到切断所述转子与所述离合器输出部及所述离合器输入部之间的连接的空挡状态。
根据上述结构，在二次电池中储存有足够的电力而无法利用电动机再生时、或者在电动机发生故障时等仅利用内燃机的驱动力使车辆行驶的情况下，能够使切换机构成为空挡状态，防止电动机的带动而引起的效率降低。

而且，第4制动器B4配置在第2行星齿轮机构PGS2的径向外侧，第3制动器B3配置在第3离合器C3的径向外侧，第1制动器B1配置在第3行星齿轮机构PGS3的径向外侧，第2制动器B2配置在第1离合器C1的径向外侧。这样，4个制动器B1～B4配置在行星齿轮机构或者离合器的径向外侧，由此，与将制动器B1～B4连同行星齿轮机构以及离合器一起并列配置在输入轴2的轴线上的情况相比，能够实现自动变速器TM的轴向长度的缩短化。另外，也可以将第4制动器B4配置在第2离合器C2的径向外侧，将第3制动器B3配置在第2行星齿轮机构PGS2的径向外侧。
接下来，参照图3和图4对实施方式的自动变速器TM建立各个变速挡的情况进行说明。
在建立第1挡的情况下，使作为双向离合器的第1制动器B1成为反转阻止状态(图4的“R”)，使第2制动器B2和第3制动器B3成为固定状态。通过使第1制动器B1成为反转阻止状态从而阻止了第3连结体Cc－Cd的反转。此外，通过使第2制动器B2成为固定状态，第3行星齿轮机构PGS3的太阳轮Sc(第7要素)的旋转速度变成“0”。而且，第3连结体Cc－Cd的旋转速度也变成“0”。
由此，第3行星齿轮机构PGS3的第7至第9这3个要素Sc、Cc、Rc成为不能相对旋转的锁定状态，包含第3行星齿轮机构PGS3的齿环Rc(第9要素)的第1连结体Ca－Cb－Rc的旋转速度也变成“0”。而且，连结有输出部3的第4行星齿轮机构PGS4的齿环Rd(第10要素)的旋转速度变成图4所示的“第1挡”，第1挡被建立。
另外，不需要为了建立第1挡而使第3制动器B3成为固定状态，但是为了能够从第1挡顺利地变速到后述的第2挡，在第1挡使其成为固定状态。此外，当在第1挡时使发动机制动器起效的情况下，只要将由双向离合器构成的第1制动器B1切换到固定状态(图4的“L”)即可。
在建立第2挡的情况下，使作为双向离合器的第1制动器B1成为反转阻止状态(图4的“R”)，使第2制动器B2和第3制动器B3成为固定状态，使第3离合器C3成为连结状态。通过使第1制动器B1成为反转阻止状态从而允许第3连结体Cc－Cd的正转。此外，通过使第2制动器B2成为固定状态，第3行星齿轮机构PGS3的太阳轮Sc(第7要素)的旋转速度变成“0”。此外，通过使第3制动器B3成为固定状态，第2行星齿轮机构PGS2的太阳轮Sb(第6要素)的旋转速度变成“0”。
此外，通过使第3离合器C3成为连结状态，从而第2连结体Ra－Sd的旋转速度变成与第2行星齿轮机构PGS2的太阳轮Sb(第6要素)的旋转速度相同速度的“0”。而且，连结有输出部3的第4行星齿轮机构PGS4的齿环Rd(第10要素)的旋转速度变成图3所示的“第2挡”，第2挡被建立。
在建立第3挡的情况下，使作为双向离合器的第1制动器B1成为反转阻止状态，使第2制动器B2和第3制动器B3成为固定状态，使第2离合器C2成为连结状态。通过使第1制动器B1成为反转阻止状态，从而允许第3连结体Cc－Cd的正转。此外，通过使第2制动器B2成为固定状态，从而第3行星齿轮机构PGS3的太阳轮Sc(第7要素)的旋转速度变成“0”。此外，通过使第3制动器B3成为固定状态，从而第2行星齿轮机构PGS2的太阳轮Sb(第6要素)的旋转速度变成“0”。
此外，通过使第2离合器C2成为连结状态，从而第2行星齿轮机构PGS2的齿环Rb(第4要素)的旋转速度变成与连结于输入轴2的第1行星齿轮机构PGS1的太阳轮Sa(第1要素)的旋转速度相同速度的“1”。由于第2行星齿轮机构PGS2的太阳轮Sb(第6要素)的旋转速度变成“0”、齿环Rb(第4要素)的旋转速度变成“1”，因此，行星架Cb(第5要素)的旋转速度，即第1连结体Ca－Cb－Rc的旋转速度变成i/(i+1)。而且，连结有输出部3的第4行星齿轮机构PGS4的齿环Rd(第10要素)的旋转速度变成图3所示的“第3挡”，第3挡被建立。
在建立第4挡的情况下，使作为双向离合器的第1制动器B1成为反转阻止状态，使第2制动器B2成为固定状态，使第2离合器C2和第3离合器C3成为连结状态。通过使第1制动器B1成为反转阻止状态，从而允许第3连结体Cc－Cd的正转。此外，通过使第2制动器B2成为固定状态，从而第3行星齿轮机构PGS3的太阳轮Sc(第7要素)的旋转速度变成“0”。
此外，通过使第3离合器C3成为连结状态，从而第2行星齿轮机构PGS2的太阳轮Sb(第6要素)与第2连结体Ra－Sd以相同速度旋转。由此，在第1行星齿轮机构PGS1与第2行星齿轮机构PGS2之间，行星架Ca(第2要素)和行星架Cb(第5要素)相连结，齿环Ra(第3要素)和太阳轮Sb(第6要素)相连结，在使第3离合器C3成为连结状态的第4挡时，能够通过第1行星齿轮机构PGS1和第2行星齿轮机构PGS2描绘由4个旋转要素构成的1个共线图。
而且，通过使第2离合器C2成为连结状态，第2行星齿轮机构PGS2的齿环Rb(第4要素)的旋转速度变成与第1行星齿轮机构PGS1的太阳轮Sa(第1要素)的旋转速度相同速度的“1”，由第1行星齿轮机构PGS1和第2行星齿轮机构PGS2构成的4个旋转要素中的2个旋转要素的旋转速度变成相同速度“1”。
因此，第1行星齿轮机构PGS1和第2行星齿轮机构PGS2的各个要素成为不能相对旋转的锁定状态，第1行星齿轮机构PGS1和第2行星齿轮机构PGS2的所有的要素的旋转速度变成“1”。而且，第3连结体Cc－Cd的旋转速度变成j/(j+1)，连结有输出部3的第4行星齿轮机构PGS4的齿环Rd(第10要素)的旋转速度变成图3所示的“第4挡”，第4挡被建立。
在建立第5挡的情况下，使作为双向离合器的第1制动器B1成为反转阻止状态，使第2制动器B2成为固定状态，使第1离合器C1和第2离合器C2成为连结状态。通过使第1制动器B1成为反转阻止状态，从而允许第3连结体Cc－Cd的正转。此外，通过使第2制动器B2成为固定状态，从而第3行星齿轮机构PGS3的太阳轮Sc(第7要素)的旋转速度变成“0”。
此外，通过使第1离合器C1成为连结状态，从而第3连结体Cc－Cd的旋转速度成为与第1行星齿轮机构PGS1的太阳轮Sa(第1要素)的旋转速度相同的速度“1”。而且，连结有输出部3的第4行星齿轮机构PGS4的齿环Rd(第10要素)的旋转速度变成图3所示的“第5挡”，第5挡被建立。
另外，不需要为了建立第5挡而使第2离合器C2成为连结状态。但是，由于在第4挡和后述的第6挡时需要使第2离合器C2成为连结状态，因此，为了能够顺利地进行从第5挡向第4挡的降挡和从第5挡向后述的第6挡的升挡，在第5挡时也使其成为连结状态。
在建立第6挡的情况下，使作为双向离合器的第1制动器B1成为反转阻止状态，使第1至第3这3个离合器C1～C3成为连结状态。通过使第1制动器B1成为反转阻止状态，从而允许第3连结体Cc－Cd的正转。
此外，通过使第2离合器C2和第3离合器C3成为连结状态，如在第4挡时所做说明那样，第1行星齿轮机构PGS1和第2行星齿轮机构PGS2的各个要素成为不能相对旋转的状态，第2连结体Ra－Sd的旋转速度变成“1”。此外，通过使第1离合器C1成为连结状态，从而第3连结体Cc－Cd的旋转速度变成“1”。
因此，第4行星齿轮机构PGS4的行星架Cd(第11要素)和太阳轮Sd(第12要素)变成相同的速度“1”，各个要素成为不能相对旋转的锁定状态。而且，连结有输出部3的第4行星齿轮机构PGS4的齿环Rd(第10要素)的旋转速度变成图3所示的“第6挡”的“1”，第6挡被建立。
在建立第7挡的情况下，使作为双向离合器的第1制动器B1成为反转阻止状态，使第3制动器B3成为固定状态，使第1离合器C1和第2离合器C2成为连结状态。通过使第1制动器B1成为反转阻止状态，从而允许第3连结体Cc－Cd的正转。
此外，通过使第3制动器B3成为固定状态，从而第2行星齿轮机构PGS2的太阳轮Sb(第6要素)的旋转速度变成“0”。此外，通过使第2离合器C2成为连结状态，第2行星齿轮机构PGS2的齿环Rb(第4要素)的旋转速度变成与第1行星齿轮机构PGS1的太阳轮Sa(第1要素)的转速相同的速度“1”，包含第2行星齿轮机构PGS2的行星架Cb(第5要素)的第1连结体Ca－Cb－Rc的旋转速度变成i/(i+1)。
此外，通过使第1离合器C1成为连结状态，从而第3连结体Cc－Cd的旋转速度变成与连结于输入轴2的第1行星齿轮机构PGS1的太阳轮Sa(第1要素)的旋转速度相同的速度“1”。而且，连结有输出部3的第4行星齿轮机构PGS4的齿环Rd(第10要素)的旋转速度变成图3所示的“第7挡”，第7挡被建立。
在建立第8挡的情况下，使作为双向离合器的第1制动器B1成为反转阻止状态，使第3制动器B3成为固定状态，使第1离合器C1和第3离合器C3成为连结状态。通过使第1制动器B1成为反转阻止状态，从而允许第3连结体Cc－Cd的正转。

建立第9挡的情况下，使作为双向离合器的第1制动器B1成为反转阻止状态，使第3制动器B3和第4制动器B4成为固定状态，使第1离合器C1成为连结状态。通过使第1制动器B1成为反转阻止状态，从而允许第3连结体Cc－Cd的正转。
此外，通过使第3制动器B3成为固定状态，从而第2行星齿轮机构PGS2的太阳轮Sb(第6要素)的旋转速度变成“0”。此外，通过使第4制动器B4成为固定状态，从而第2行星齿轮机构PGS2的齿环Rb(第4要素)的旋转速度也变成“0”。因此，第2行星齿轮机构PGS2的各个要素Sb、Cb、Rb成为不能相对旋转的锁定状态，包含第2行星齿轮机构PGS2的行星架Cb(第5要素)的第1连结体Ca－Cb－Rc的旋转速度也变成“0”。
此外，通使第1离合器C1成为连结状态，从而第3连结体Cc－Cd的旋转速度变成与第1行星齿轮机构PGS1的太阳轮Sa(第1要素)的旋转速度相同的速度“1”。而且，连结有输出部3的第4行星齿轮机构PGS4的齿环Rd(第10要素)的旋转速度变成图3所示的“第9挡”，第9挡被建立。
在建立第10挡的情况下，使作为双向离合器的第1制动器B1成为反转阻止状态，使第4制动器B4成为固定状态，使第1离合器C1和第3离合器C3成为连结状态。通过使第1制动器B1成为反转阻止状态，从而允许第3连结体Cc－Cd的正转。
此外，通过使第3离合器C3成为连结状态，从而第2连结体Ra－Sd和第2行星齿轮机构PGS2的太阳轮Sb(第6要素)以相同速度旋转。此外，通过使第4制动器B4成为固定状态，从而第2行星齿轮机构PGS2的齿环Rb(第4要素)的旋转速度变成“0”。此外，通过使第1离合器C1成为连结状态，从而第3连结体Cc－Cd的旋转速度变成与第1行星齿轮机构PGS1的太阳轮Sa(第1要素)的旋转速度相同的速度“1”。而且，连结有输出部3的第4行星齿轮机构PGS4的齿环Rd(第10要素)的旋转速度变成图3所示的“第10挡”，第10挡被建立。

另外，图3中的虚线所示的速度线表示：4个行星齿轮机构PGS1～PGS4中，跟随着进行动力传递的行星齿轮机构，其他行星齿轮机构的各个要素进行旋转(空转)。
图4是对上述各个变速挡时的离合器C1～C3、制动器B1～B4的状态汇总进行示出的图，第1至第3这3个离合器C1～C3以及第2制动器B2至第4制动器B4的列中的“○”表示连结状态或者固定状态，空白栏表示开放状态。此外，第1制动器B1的列中的“R”表示反转阻止状态，“L”表示固定状态。
此外，标有下划线的“R”和“L”表示由于第1制动器B1工作而第3连结体Cc－Cd的旋转速度变成“0”。此外，虽然“R/L”表示：在通常时是反转阻止状态“R”，但是在发动机制动器起效的情况下，切换到固定状态“L”。
此外，图4还示出了设第1行星齿轮机构PGS1的齿轮比h为2.734、第2行星齿轮机构PGS2的齿轮比i为1.614、第3行星齿轮机构PGS3的齿轮比j为2.681、第4行星齿轮机构PGS4的齿轮比k为1.914的情况下的各个变速挡的变速比(输入轴2的旋转速度/输出部3的旋转速度)和公比(各个变速挡之间的变速比之比。规定变速挡的变速比除以比规定变速挡高1挡的高速侧的变速挡的变速比而得到的值。)，由此可知，能够适当地设定公比。
接下来，参照图5A至图5C，对双向离合器进行详细说明。第1制动器B1由双向离合器构成，该双向离合器能够切换到将第3连结体Cc－Cd固定于壳体1的固定状态以及允许第3连结体Cc－Cd的正转并阻止其反转的反转阻止状态。在图5A至图5C中示出该双向离合器的一例并进行具体说明。
图5A的作为第1制动器B1的双向离合器TW具有：与第3连结体Cc－Cd连结的内圈TW1；隔开间隔地配置在内圈TW1的径向外侧、并且与壳体1连结的外圈TW2；以及配置在内圈TW1和外圈TW2之间的保持圈TW3。
在内圈TW1的外周面上形成有多个凸轮面TW1a。在保持圈TW3上与凸轮面TW1a对应设置有多个切口孔TW3a。在该切口孔TW3a中收纳有辊TW4。此外，双向离合器TW具有省略图示的啮合机构。
啮合机构构成为能够切换到连结外圈TW2和保持圈TW3的外连结状态以及连结内圈TW1和保持圈TW3的内连结状态。
此外，辊TW4的直径被设定成：如图5A所示，在辊TW4存在于凸轮面TW1a的中央部时，空出间隙A，如图5B和图5C所示，在辊TW4存在于凸轮面TW1a的端部时，辊TW4与内圈TW1和外圈TW2接触。
在通过啮合机构而处于外圈TW2和保持圈TW3相连结的外连结状态时，不论内圈TW1要向正转和反转中的哪一方旋转，如图5B和图5C所示，由于保持圈TW3都固定于壳体1，因此，辊TW4位于凸轮面TW1a的端部。
此时，辊TW4被凸轮面TW1a和外圈TW2的内周面所夹，内圈TW1的旋转被阻止。即，双向离合器TW成为固定状态。
省略图示的啮合机构构成为：在连结内圈TW1和保持圈TW3的内连结状态下，如图5B所示那样，成为切口孔TW3a位于凸轮面TW1a的一个端部的状态。
若设图5B中的顺时针方向为反转方向，则该双向离合器TW通过成为连结内圈TW1和保持圈TW3的内连结状态而成为反转阻止状态。
此处，图6中示出车速从停车状态以一定的加速度上升的情况下的曲线图。如图6所示，在电动机MG的旋转速度没有达到内燃机ENG的可起动转速的低速行驶状态的情况下，需要使电动机MG的旋转速度上升到内燃机ENG的可起动转速。
但是，电动机MG的旋转速度的上升部分不能传递到驱动轮，因此，还考虑在自动变速器TM的摩擦离合器或摩擦制动器中调整压紧力来进行传递。但是，在调整利用自动变速器TM的摩擦离合器或摩擦制动器传递的驱动力的情况下，需要使容量比以往大以耐受摩擦离合器或摩擦制动器在起步时产生的热等，不能再直接使用已有的自动变速器。
因此，在第1实施方式的动力传递装置PT中，在动力传递装置PT上设置起步离合器110，调整通过该起步离合器110输入到自动变速器TM的驱动力。以下，对动力传递装置PT进行详细说明。
如图1所示，动力传递装置PT具有：与双质量飞轮FW连接的筒状的离合器输入部120；和具有配置在离合器输入部120的内侧的内侧筒部131的离合器输出部130。在离合器输入部120和内侧筒部131之间，设置有起步离合器110，由此，离合器输入部120与离合器输出部130能够自如解除地连接。
电动机MG以沿周向覆盖起步离合器110的方式配置在离合器输入部120和离合器输出部130的径向外侧。电动机MG的转子MGa上设置有切换机构140，该切换机构140能够有选择地与离合器输入部120和离合器输出部130连接。
切换机构140具有：配置在内燃机ENG侧的多个内燃机侧滚珠141；沿周向隔开间隔地保持该内燃机侧滚珠141的内燃机侧保持器142；配置在自动变速器TM侧的多个变速器侧滚珠143；沿周向隔开间隔地保持该变速器侧滚珠143的变速器侧保持器144；以及将内燃机侧保持器142和变速器侧保持器144固定于径向内侧的圆筒状的固定部145。
固定部145构成转子MGa的一部分。在固定部145的内侧配置有在旋转轴线方向上移动自如的圆筒状的滑块146。滑块146的旋转轴线方向的两端成为厚度朝向径向外侧逐渐变小的倾斜面146a。
此外，在滑块146的内周面的中央部处设置有向径向内侧突出的环状突部146b。在该环状突部146b的内燃机ENG侧的侧面和内燃机侧保持器142之间配置作为施力部的螺旋弹簧147，螺旋弹簧147经由环状突部146b对滑块146向自动变速器TM侧施力。
被螺旋弹簧147施力的滑块146由于倾斜面146a而插入到变速器侧滚珠143的径向外侧，变速器侧滚珠143向径向内侧移动。在离合器输出部130的外周面上设置半圆状的输出侧收容孔132，该输出侧收容孔132收容借助于滑块146而向径向内侧移动的变速器侧滚珠143。如图7所示，通过变速器侧滚珠143与输出侧收容孔132嵌合，由此，固定部145与离合器输出部130卡合。将该状态定义为输出侧连接状态。
输出侧收容孔132形成为比变速器侧滚珠143的半径浅。由此，在变速器侧滚珠143没有借助于滑块146向径向内侧移动的情况下，半圆状的输出侧收容孔132成为引导件，在固定部145和离合器输出部130之间产生旋转速度差(以下、称为旋转差)时，变速器侧滚珠143向径向外侧脱出，基于变速器侧滚珠143实现的固定部145和离合器输出部130的卡合被解除(参照图8)。
此外，在环状突部146b的自动变速器TM侧的侧面、固定部145和变速器侧保持器144之间划分出液压室148。在离合器输出部130、固定部145、变速器侧保持器144上设置有向该液压室148提供液压的油路149。通过该液压室148和油路149构成第1实施方式的液压式致动器的一部分。
如图9所示，当从油路149向液压室148供给规定的液压时，滑块146抵抗螺旋弹簧147的作用力而向内燃机ENG侧移动。然后，向内燃机ENG侧移动的滑块146由于倾斜面146a而插入内燃机侧滚珠141的径向外侧，内燃机侧滚珠141向径向内侧移动。
在离合器输入部120的外周面上设置有半圆状的输入侧收容孔122，该输入侧收容孔122收容借助于滑块146而向径向内侧移动的内燃机侧滚珠141。通过内燃机侧滚珠141与输入侧收容孔122嵌合，由此，固定部145与离合器输入部120卡合(参照图7)。将该状态定义为输入侧连接状态。
输入侧收容孔122形成为比内燃机侧滚珠141的半径浅。由此，在内燃机侧滚珠141没有借助于滑块146向径向内侧移动的情况下，半圆状的输入侧收容孔122成为引导件，当在固定部145和离合器输入部120之间产生旋转差时，内燃机侧滚珠141向径向外侧脱出，基于内燃机侧滚珠141实现的固定部145和离合器输入部120的卡合被解除(参照图8)。
根据第1实施方式的动力传递装置PT，在仅依靠电动机MG的行驶时，通过使滑块146向变速器TM侧滑动，并且使起步离合器110开放，能够切断电动机MG和内燃机ENG的连接，不会使效率降低。
此外，不需要变更以往的带变矩器的变速器的离合器容量，仅通过替代变矩器而将第1实施方式的动力传递装置PT组装到自动变速器TM中就能够作为混合动力用的变速器，能够实现制造工序的简化以及低廉的制造成本。
另外，在第1实施方式的动力传递装置PT中，对将作为施力部的螺旋弹簧147配置在内燃机ENG侧，将液压室148配置在自动变速器TM侧的装置进行了说明。但是，本发明的动力传递装置并不限定于上述装置。例如，也可以将施力部配置在变速器侧，将液压室配置在内燃机侧。
此外，作为施力部并不限定于螺旋弹簧147，也可以利用其它部件，例如，弹性体、流体压(液压)进行施力。
此外，也可以将动力传递装置PT构成为：通过调节液压，而能够成为内燃机侧滚珠141和变速器侧滚珠143中的任意一方都不被滑块146向径向内侧按下的空挡状态。通过以这样的方式构成，在二次电池中储存有足够的电力而无法利用电动机再生时、或者在电动机MG发生故障时等仅利用内燃机ENG的驱动力使车辆行驶的情况下，能够使切换机构140成为空挡状态，防止电动机MG的带动引起的效率的降低。
此外，也可以如下地构成：在固定部145的内周面上设置磁铁，在内燃机侧滚珠141或者变速器侧滚珠143没有被滑块146向径向内侧按下时，使磁铁贴合于固定部145的内周面，内燃机侧滚珠141或者变速器侧滚珠143向径向外侧扩展。另外，借助于电动机MG的磁性，在固定部145起到磁铁的作用的情况下，即使不在固定部145的内周面上设置磁铁也能够得到同样的效果。
此外，固定部145也可以与转子MGa是一体的。此外，虽然使用液压致动器进行了说明，但是也可以使用电动致动器使滑块移动。
此外，在第1实施方式的动力传递装置PT中，作为变速器而对行星齿轮机构进行了说明，但是本发明的变速器并不限于此。例如，本发明的变速器也可以是无级变速器。
[第2实施方式]
参照图10至图12，对本发明的第2实施方式的动力传递装置PT进行说明。另外，针对与第1实施方式相同的结构标记相同的标号而省略其说明。
第2实施方式的圆筒状的滑块146设置有：设置在其内周面的变速器TM侧的端部的变速器侧内齿146c；和设置在其内周面的内燃机ENG侧的端部的内燃机侧内齿146d。
变速器侧内齿146c具有朝向变速器TM侧变尖成V字型的侧面146e。内燃机侧内齿146d具有朝向内燃机侧变尖成V字型的侧面146f。
在离合器输出部130的外周面以如下的方式设置有输出侧外齿133，在滑块146被螺旋弹簧147施力而向变速器TM侧移动时，该输出侧外齿133与变速器侧内齿146c啮合。通过变速器侧内齿146c和输出侧外齿133啮合，从而固定部145和离合器输出部130卡合，固定部145和离合器输入部120的卡合被解除。
在离合器输入部120的外周面上以如下的方式设置有输入侧外齿123：在滑块146抵抗螺旋弹簧147的作用力而借助于供给到液压室148的液压向内燃机ENG侧移动时，该输入侧外齿123与内燃机侧内齿146d啮合。通过内燃机侧内齿146d和输入侧外齿123啮合，从而固定部145和离合器输入部120卡合，固定部145和离合器输出部130的卡合被解除。
第2实施方式的螺旋弹簧147相对于固定部145以对滑块146向变速器TM侧施力的方式配置。
根据第2实施方式的动力传递装置PT，在仅依靠电动机MG行驶时，通过使滑块146向变速器TM侧滑动，并且使起步离合器110断开，能够断开电动机MG和内燃机ENG之间的连接，不会使效率降低。
此外，不需要变更以往的带变矩器的变速器的离合器容量，仅通过替代变矩器而将第2实施方式的动力传递装置PT组装到自动变速器TM中就能够作为混合动力用的变速器，能够实现制造工序的简化以及低廉的制造成本。
另外，在第2实施方式的动力传递装置PT中，也是对将作为施力部的螺旋弹簧147配置在内燃机ENG侧，将液压室148配置在自动变速器TM侧的装置进行了说明。但是，本发明的动力传递装置并不限定于此。例如，也可以将施力部配置在变速器侧，将液压室配置在内燃机侧。
此外，作为施力部并不限定于螺旋弹簧147，也可以利用其它部件，例如，弹性体、流体压(液压)进行施力。
此外，也可以如下地构成动力传递装置PT：通过调节液压，能够成为滑块146的内燃机侧内齿146d和变速器侧内齿146c中的任意一方都不卡合的空挡状态。通过以这样的方式构成，在二次电池中储存有足够的电力而无法利用电动机再生时、或者在电动机MG发生故障时等仅利用内燃机ENG的驱动力使车辆行驶的情况下，能够使切换机构140成为空挡状态，防止电动机MG的带动而引起的效率的降低。
此外，在第2实施方式的动力传递装置PT中，变速器也不限定于行星齿轮机构，也可以是其他变速器，例如，也可以是无级变速器。
