Abstract

本发明提供一种车辆用减震器装置，其为一体地具备转矩限制装置并且NV衰减特性较高且实用的车辆用减震器装置。由于螺旋弹簧(52)被配置于外周侧，因此能够大幅度地降低螺旋弹簧(52)的弹簧刚性。而且，由于在螺旋弹簧(52)与转矩限制装置(62)之间追加了惯性板(56)，因此减震装置(38)的惯性会增加。因此，可实现能够回避扭转共振的NV衰减特性较高的减震装置(38)。此外，虽然作为增加惯性的反效果，行驶中被施加于输入轴(39)上的载荷将增大，但该载荷能够经由球轴承(57)而通过曲轴(36)来承受，从而能够防止随着惯性的增加而引起的输入轴(39)与外壳(42)的大型化。

发明内容
发明所要解决的课题
另外，例如在具备了电动机的混合动力车辆中，存在如下课题，即，由于电动机被内置在驱动单元内因此驱动系统的惯性质量将增大，从而产生共振时的振幅会增大。此外，作为改善耗油率的措施，例如在使发动机燃料过稀化时燃烧会变得不稳定，从而除了以往的作为爆发强制力占主导地位的爆发一次以外旋转0.5次这样的低次次数的强制力也处于增加趋势。由此，以往在发动机常用旋转速度以下的区域中会产生的扭转共振在发动机常用旋转速度以下的区域中也将产生，从而会给NV或驾驶性能带来影响。此外，作为改善耗油率的措施，如果实施变速器的高速档化、驱动系统的轻量化，则成为轰鸣声与齿轮击打声的原因的驱动系统的振动传递特性容易恶化。
为了解决这些课题，从而考虑到将减震器装置的弹簧刚性降低、或者增大减震器装置的惯性等来将共振频率区域调整为更低的区域。然而，从减震器装置的搭载方面的制约等观点出发，调整成所需的弹簧刚性以及惯性是非常困难的。例如，当将专利文献1的减震器装置应用于混合动力车辆时，由于惯性较小从而降低至所需的共振频率区域将会受到限制。另一方面，如专利文献2的图6所示的减震器装置那样，由于在输入轴上设置了惯性体的结构中惯性变大，因此大体上可实现使共振频率区域降低。然而，由于施加于输入轴(行星齿轮架轴42A)上的载荷也会增大与设置了惯性体相对应的量，因此需要使输入轴增大，其结果为，装置会变得大型化因此无法称之为实用的减震器装置。
本发明为以上述的情形为背景而完成的发明，其目的在于，提供一种在一体地具备转矩限制装置的车辆用减震器装置中，NV衰减特性较高的实用的车辆用减震器装置。
用于解决课题的方法
为了实现上述目的，第一发明的宗旨为(a)一种车辆减震器装置，其被设置于发动机与动力传递装置之间的动力传递路径上，所述车辆减震器装置的特征在于，具备：(b)第一板，其被连结在发动机的曲轴上；(c)第二板，其经由弹性体而被连结在该第一板上；(d)惯性体，其被连结在该第二板上；(e)支承部件，其与所述第一板一起被连结在所述曲轴上；(f)轴承，其被插设于该支承部件与所述惯性体之间；(g)第三板，其与所述惯性体连结，(h)第四板，其被连结在所述动力传递装置的输入轴上；(i)转矩限制装置，其被设置于该第三板与该第四板之间。
发明效果
根据该方式，由于在弹性体与转矩限制机构之间追加设置了弹性体，因此减震器装置的输入轴侧的惯性会增加。而且，通过使惯性增加，从而能够实现降低了共振频率区域的NV衰减特性较高的减震器装置。在此，虽然作为增加惯性所导致的反效果，施加于输入轴上的载荷会变大，但通过经由轴承并利用曲轴来承受该载荷，从而施加于输入轴上的载荷也会被抑制。因此，无需随着惯性的增加而使输入轴大型化，从而成为实用的减震器装置。
此外，优选为，所述转矩限制机构被设置于与所述弹性体相比靠径向内侧且在轴向上不与该弹性体重复的位置处。根据这种方式，通过设为将转矩限制机构配置于在轴向上鼓出的弹性体的内周侧所形成的空间内的模具镶块结构，从而能够将弹性体与转矩限制机构之间的轴向上的距离缩短，进而能够将减震器装置的轴向上的长度缩短。
此外，优选为，在所述输入轴上以能够实施动力传递的方式而连结有电动机，所述转矩限制机构被设置于与所述电动机的线圈端相比靠径向的内侧且在轴向上不与该线圈端重复的位置处。根据此方式，通过采用将转矩限制机构配置于在电动机的线圈端的内周侧所形成的空间内的模具镶块结构，从而能够将减震器装置与电动机之间的轴向上的长度缩短。
此外，优选为，在所述第四板与所述支承部件之间插设有第二轴承。根据此方式，能够经由第二轴承并通过曲轴来承受第四板的载荷。因此，由于能够进一步减小被施加于输入轴上的载荷，因此能够防止输入轴的大型化。
此外，优选为，所述弹性体为圆弧状的弧形弹簧。根据此方式，由于弹性体的长度与直线状的螺旋弹簧相比而较长，从而能够确保弹簧的压缩量(缩小量、变形量)，因此能够使弹簧刚性与直线状的螺旋弹簧相比而降低。
附图说明
图1为对应用了本发明的混合动力车辆的车辆用驱动装置进行说明的概要结构图。
图2为用于对图1的减震器装置的结构进行说明的剖视图。
图3为用于对作为本发明的其他实施例的减震器装置的结构进行说明的剖视图。
具体实施方式
以下，参照附图对本发明的实施例进行详细说明。另外，在以下的实施例中附图被适当地简化或改变，从而各部分的尺寸比以及形状等未必被准确地描绘。
实施例1
图1为对应用了本发明的混合动力车辆的车辆用驱动装置10进行说明的概要结构图。车辆用驱动装置10被构成为，包括：发动机24、动力传递装置12、被设置于发动机24与动力传递装置12之间的后文叙述的减震器装置38(本发明的车辆用减震器装置)。在图1中，在该车辆用驱动装置10中，在车辆中作为主驱动源的发动机24的转矩经由后文所述的减震器装置38以及行星齿轮装置26而被传递至车轮侧输出轴14，并且转矩从该车轮侧输出轴14起经由差动齿轮装置16而被传递到左右一对驱动轮18。此外，在该车辆用驱动装置10中设置有第二电动机MG2，该第二电动机MG2能够选择性地执行电动机驱动控制以及再生控制，其中，所述电动机驱动控制输出用于行驶的驱动力，所述再生控制用于回收能量，该第二电动机MG2经由自动变速器22而连结于上述车轮侧输出轴。因此，从第二电动机MG2向车轮侧输出轴被传递的输出转矩会根据通过该自动变速器22而被设定的变速比γs(＝第二电动机MG2的转速Nmg2/车轮侧输出轴的转速Nout)而被增减。
由于被安装在第二电动机MG2与驱动轮18之间的动力传递路径上的自动变速器22被构成为能够使变速比γs大于“1”的多级变速比成立、并且能够在从第二电动机MG2输出转矩的电动机驱动时使该转矩增大并向车轮侧输出轴进行传递，因此能够将第二电动机MG2构成为更低电容或小型化。由此，例如，为了在随着高车速而车轮侧输出轴的转速Nout增大的情况下，将第二电动机MG2的运转效率维持在良好的状态，从而使变速比γs减小而使第二电动机MG2的转速(以下，称之为第二电动机转速)Nmg2降低，或者在车轮侧输出轴的转速Nout降低的情况下，使变速比γs增大而使第二电动机转速Nmg2增大。
上述动力传递装置12被构成为具备第一电动机MG1以及第二电动机MG2，并且将发动机24的转矩向驱动轮18进行传递。上述发动机24为汽油发动机或柴油发动机等的使燃料燃烧而输出动力的公知的内燃机，并且该发动机24被构成为，通过以微型计算机为主体的未图示的发动机控制用的电子控制装置(E-ECU)而对节气门开度、吸入空气量、燃料供给量、点火正时等运转状态实施电气控制。在上述电子控制装置中，被供给有来自对加速踏板的操作量进行检测的加速器操作量传感器AS、用于对制动踏板有无操作进行检测的制动器传感器BS等的检测信号。
上述第一电动机MG1(电动机)例如为同步电动机，且被构成为选择性地产生作为使驱动转矩产生的电动机的功能、和作为发电机的功能，并且经由逆变器30而与蓄电池、电容器等的蓄电装置32连接。而且，通过利用以微型计算机为主体的未图示的电机发电机控制用的电子控制装置(MG-ECU)而对该逆变器30实施控制，从而对第一电动机MG1的输出转矩或再生转矩实施调节或设定。
行星齿轮装置26为，将太阳齿轮S0、内啮合齿轮R0以及行星齿轮架CA0作为三个旋转元件而具备并产生公知的差动作用的单小齿轮型的行星齿轮机构，该内啮合齿轮R0相对于该太阳齿轮S0而被配置在同心圆上，该行星齿轮架CA0以使与这些太阳齿轮S0以及内啮合齿轮R0相啮合的小齿轮P0自转且公转自如的方式对该小齿轮P0进行支承。行星齿轮装置26以与发动机24以及自动变速器22同心的方式而设置。由于行星齿轮装置26以及自动变速器22被构成为关于中心线而对称，因此在图1中省略了其下半部分。
在本实施例中，发动机24的曲轴36经由减震器装置38以及动力传递装置39的输入轴39而与行星齿轮装置26的行星齿轮架CA0连结。与此相对，在太阳齿轮S0上连结有第一电动机MG1，在内啮合齿轮R0上连结有车轮侧输出轴14。该行星齿轮架CA0作为输入元件而发挥功能，太阳齿轮S0作为反作用力元件而发挥功能，内啮合齿轮R0作为输出元件而发挥功能。另外，减震器装置38对应于本发明的车辆用减震器装置，输入轴39对应于本发明的动力传递装置的输入轴。
在上述行星齿轮装置26中，由于相对于被输入到行星齿轮架CA0的发动机24的输出转矩而由第一电动机MG1所产生的反作用力转矩被输入到太阳齿轮S0时，在成为输出元件的内啮合齿轮R0上会出现直达转矩，因此第一电动机MG1作为发电机而发挥功能。此外，在内啮合齿轮R0的转速即车轮侧输出轴14的转速(输出轴转速)Nout为固定时，能够通过使第一电动机MG1的转速Nmg1上下变化来使发动机24的转速(发动机转速)Ne连续地(无级地)变化。换言之，在输入轴39上经由行星齿轮装置26而以能够实施动力传递的方式连结有第一电动机MG1。
本实施例的所述自动变速器22通过一组拉维娜型行星齿轮机构而被构成。即，在自动变速器22中，设置有第一太阳齿轮S1与第二太阳齿轮S2，该第一太阳齿轮S1与阶式小齿轮P1的大径部啮合，并且该阶式小齿轮P1的小径部与小齿轮P2啮合，该小齿轮P2与以与所述各太阳齿轮S1、S2同心的方式被配置的内啮合齿轮R1(R2)啮合。上述各小齿轮P1、P2以自转且公转自如的方式通过共同的行星齿轮架CA1(CA2)而被分别被保持。此外，第二太阳齿轮S2与小齿轮P2啮合。
所述第二电动机MG2(电动机)通过由所述电机发电机控制用的电子控制装置(MG-ECU)经由逆变器40来对其进行控制，从而作为电动机或发电机而发挥功能，进而对辅助用输出转矩或再生转矩进行调节或设定。在第二太阳齿轮S2上连结有该第二电动机MG2，并且上述行星齿轮架CA1与车轮侧输出轴连结。第一太阳齿轮S1和内啮合齿轮R1将与各小齿轮P1、P2一起构成相当于双小齿轮型行星齿轮装置的机构，此外，第二太阳齿轮S2和内啮合齿轮R1将与小齿轮P2一起构成相当于单小齿轮型行星齿轮装置的机构。
而且，在自动变速器22上设置有第一制动器B1以及第二制动器B2，该第一制动器B1为，为了选择性地对第一太阳齿轮S1进行固定而被设置于该第一太阳齿轮S1与作为非旋转部件的外壳42之间，该第二制动器B2为，为了选择性地对内啮合齿轮R1进行固定而被设置于该内啮合齿轮R1与外壳42之间。该制动器B1、B2为通过摩擦力而产生制动力的所谓的摩擦卡合装置，能够采用多板形式的卡合装置或带形式的卡合装置。而且，这些制动器B1、B2被构成为，分别根据通过液压缸等的制动器B1用液压致动器、制动器B2用液压致动器而产生的卡合压力而使其转矩容量连续地变化。
通过以上的方式而被构成的自动变速器22被构成为，第二太阳齿轮S2作为输入元件而发挥功能，此外行星齿轮架CA1作为输出元件而发挥功能，当第一制动器B1被卡合时使大于“1”的变速比γsh的高速级H成立，当代替第一制动器B1而第二制动器B2被卡合时，与该高速级H的变速比γsh相比而较大的变速比γsl的低速级L成立。即，自动变速器22为二级变速器，这些变速级H以及L之间的变速基于车速V、要求驱动力(或者加速器操作量)等的行驶状态而被执行。更加具体而言，以将变速级区域预先作为映射图(变速线图)而规定，并根据所检测到的运转状态而设定其中某一变速级的方式来实施控制。
图2为用于对图1的减震器装置38的结构进行说明的剖视图。减震器装置38在外壳42内，以旋转轴心C作为中心而被设置在发动机24与动力传递装置12之间的动力传递路径上。
减震器装置38被构成为，包括：第一圆板50，其被连结在发动机24的曲轴36上；环状的支承部件51，其与第一圆板50一起被连结在曲轴36上；螺旋弹簧52，其以被第一圆板50的外周部覆盖的方式被收纳；第二圆板54，其能够经由被配置于第一圆板50的外周部上的螺旋弹簧52而以实施动力传递的方式被连结在第一圆板50上；惯性板56，其被连结在第二圆板54的内周部上；球轴承57，其被插设于惯性板56与支承部件51之间；第三圆板58，其被连结在惯性板56的外周部上；轴套60，其内周部通过花键嵌合而被连结在输入轴39上；转矩限制机构62，其被设置于第三圆板58与轴套60之间。另外，第一圆板50对应于本发明的第一板，第二圆板54对应于本发明的第二板，惯性板56对应于本发明的惯性体，第三圆板58对应于本发明的第三板，轴套60对应于本发明的第四板，螺旋弹簧52对应于本发明的弹性体，球轴承57对应于本发明的轴承。
第一圆板50的内周部通过螺栓64而与支承部件51一起被连接于曲轴36上，并且与发动机24一起以旋转轴心C为中心而一体地旋转。第一圆板50由圆盘状的主板部50a与圆盘状的副板部50b构成，所述圆盘状的主板部50a的内周部与曲轴36连结，所述圆盘状的副板部50b的外周部通过焊接而与主板部50a的外周部连接。主板部50a的外周部以在轴向上朝向发动机24侧而鼓出为碗状的方式被形成。此外，副板部50b的外周部以在轴向上朝向动力传递装置12侧而鼓出为碗状的方式而被形成。而且，通过使主板部50a的外周端部与副板部50b的外周端部相互焊接在一起从而在第一圆板50的外周部处形成了用于收纳螺旋弹簧52的截面大致呈圆形的空间。另外，由于第一圆板50也具有比较大的惯性质量，从而具有作为惯性体的功能。
螺旋弹簧52被收纳于在第一圆板50的外周部处形成的所述空间内，并且在第一圆板50与第二圆板54之间发生弹性形变且传递动力。螺旋弹簧52由第一弹簧52a与被收纳(内插)于该第一弹簧52a内的第二弹簧52b构成。第一弹簧52a以及第二弹簧52b通过被形成为圆弧状(弧状)的所谓弧形弹簧而构成，并且在减震器装置38中，被形成为半圆状的弹簧52a、52b各自被使用了两个。此外，被收纳于第一弹簧52a内的第二弹簧52b的长度被形成为与第一弹簧52a相比而较短，并且以成为预定的扭转角以上的方式被压缩。以该方式，由于通过使螺旋弹簧52由弧形弹簧构成从而其长度(自由长度)变长，因此能够使用低弹簧刚性的螺旋弹簧52。
第二圆板54呈圆板形状，并且在轴向上被配置于在第一圆板50的主板部50a与副板部50b之间所形成的间隙中。在第二圆板54的外周部上形成有两个半圆状的空间，并且在两个该空间中分别收纳有螺旋弹簧52。此外，第二圆板54的内周部通过铆钉66而与惯性板56的内周部连结。
惯性板56呈具有预定厚度的圆盘形状，并且被设置在螺旋弹簧52与转矩限制机构62之间的动力传递路径上。惯性板56的内周部通过铆钉66而与第二圆板54连接。此外，惯性板56的内周端部被配置于在径向上不与支承部件51重复的位置处，在惯性板56的内周端部与支承部件51之间插设有球轴承57。惯性板56在径向上与副板部50b的鼓出为碗状的部位相比而稍向内周侧屈曲，惯性板56的外周侧位于在轴向上与内周侧相比靠动力传递装置12侧处。具体而言，惯性板56的外周部在轴向上移动了相当于副板部50b的外周部在轴向上鼓出的部分的量。此外，通过使惯性板56屈曲，从而相对于惯性板56的外周部而在径向上的内侧形成了空间。另外，惯性板56对应于本发明的惯性体。以该方式，减震器装置38为，第一圆板50以及惯性板56分别作为惯性体而发挥功能的所谓的飞轮减震器。
惯性板56的外周部通过螺栓68而与第三圆板58的外周部连接。第三圆板58由圆板形状的主板部58a以及圆盘形状的副板部58b这两个板构成。主板部58a以及副板部58b的外周部均通过螺栓68而与惯性板56的外周部被结合在一起。因此，第三板58以旋转轴心C为中心而与惯性板56一体地旋转。此外，主板部58a与副板部58b也通过铆钉70而被结合在一起，并且惯性板56侧的铆钉70的端部被收纳于在惯性板56上所形成的切口中。另外，虽然图2为、螺栓68与铆钉70在圆周方向上被形成于相同位置的图，但实际上也可以使螺栓68与铆钉70在圆周方向上被形成于不同的位置，并将铆钉70在径向上被设置于与螺栓68相同的位置处。通过使副板部58b与惯性板56的被弯曲的部位相比在径向上向内侧稍微弯曲，从而副板部58b的内周部被收纳于通过使惯性板56弯曲而形成的内周空间内。由此，在主板部58a的内周部与副板部58b的内周部之间形成了间隙。而且，在该间隙内收纳有转矩限制机构62。
转矩限制机构62为，为了防止传递超过预先设定的限制转矩Tlim的转矩而被设置的。转矩限制机构62被构成为，包括：线板74，其内周部通过铆钉72而与轴套60的外周部结合；圆板状的压板76；圆锥状的盘簧78，其被插设于压板76与副板部58b之间；一对摩擦部件80，它们被粘贴在线板74上。
线板74呈圆板形状，并且通过其内周部利用铆钉72而与轴套60连结，从而与轴套60以及输入轴39一起绕旋转轴心C而一体地旋转。在线板74的外周部上于轴向上的两侧粘贴有一对摩擦部件80，并且在主板部58a与摩擦部件80之间、以及压板76与摩擦部件80之间能够滑动。盘簧78以预载荷状态被插设于压板76与副板部58b之间，并对压板76朝向摩擦部件80侧实施按压。而且被构成为，通过对摩擦部件80与主板部58a以及压板76之间的摩擦系数μ、盘簧78的盘簧载荷等适当地进行调节，从而当在转矩限制机构62上被输入有超过预先设定的限制转矩Tlim的转矩时，在摩擦部件80与主板部58a以及压板76之间的摩擦面上会产生滑动。
在此，转矩限制机构62被设置于与螺旋弹簧52相比靠径向的内侧且在轴向上不与螺旋弹簧52重复的位置处。由于为了形成对螺旋弹簧52进行收纳的空间从而使第一圆板50的副板部50b的外周侧在轴向上向动力传递装置12侧鼓出，因此在该鼓出的部位的内周侧形成有空间。此外，惯性板56以其内周部被收纳于该空间内的方式而弯曲，并且在该弯曲了的部位的内周侧也形成有空间。在此，转矩限制机构62以及副板部58b以在轴向上向发动机24侧鼓出的方式被形成，并且该鼓出的部位被收纳于在惯性板56的所述被弯曲了的部位的内周侧所形成的空间内。以此方式，螺旋弹簧52以及副板部50b的鼓出部分与副板部58b以及转矩限制机构62的鼓出部分以在径向上成为模具镶块的方式而配置。因此，转矩限制机构62被设置于与螺旋弹簧52相比靠径向的内侧且在轴向上不与螺旋弹簧52重复的位置处，从而螺旋弹簧52与转矩限制机构62之间的轴向上的距离变短。
此外，转矩限制机构62在径向上向外周侧被配置至螺旋弹簧52附近的位置处。在此，由于采用了副板部50b的鼓出部分与副板部58b以及转矩限制机构62的鼓出部分在径向上重叠的模具镶块结构，并且，经由第三圆板58而将转矩限制机构62固定于惯性板56上的螺栓68在径向上向外周侧被配置至与螺旋弹簧52相同的位置处，因此能够将转矩限制机构62在径向上向外周侧配置至螺旋弹簧52附近处。而且，通过将转矩限制机构62配置于外周侧，从而容易确保转矩限制机构62的转矩电容，例如能够在不增加摩擦部件80的片数等的条件下确保所需的限制转矩Tlim。
此外，在减震器装置38中，通过使第三圆板58的主板部58a与副板部58b利用铆钉70而结合在一起，从而从第三圆板58至轴套60作为独立的部件而被局部化(组件化)。因此，该被局部化了的部件可通过独立于动力传递装置21的组装线的生产线而被组装。而且，该被局部化了的部件在通过未图示的定位销而被定位了的状态下，不实施对准中心线等的情况下通过螺栓68而与惯性板56结合在一起。此外，组件化了的部件可应用于其他的形式的减震器装置等。
在以上述方式而构成的减震器装置38中，由于在螺旋弹簧52与转矩限制机构62之间设置有惯性板56，因此相对于减震器装置38的螺旋弹簧52而输入轴39侧的惯性质量会增加。此外，由于在本实施例的减震器装置38中使用了弧形弹簧结构的螺旋弹簧52，因此即使为低弹簧刚性的弹簧也能够使用。此外，由于在减震器装置38中所使用的螺旋弹簧52的数目为两个从而与现有的减震器装置相比而较少，因此能够大幅度降低弹簧刚性。由于通过实施这些惯性质量的增加以及螺旋弹簧52的低弹簧刚性化从而能够使驱动系统的共振频率区域大幅度减小，因此能够防止在发动机24的常用转速区域中所产生的扭转共振。
在此，作为设置惯性板56而导致的不良效果，施加于车辆行驶中的输入轴39上的载荷将会增大。相对于此，由于在惯性板56的内周端部与支承部件51之间插设有球轴承57，因此经由球轴承57而曲轴36能够承受该载荷，从而减小了施加在输入轴39上的载荷。另外，由于曲轴36具有非常大的刚性，因此即使经由球轴承57而所施加的载荷增加也不会产生与强度有关的问题。
此外，由于转矩限制机构62被配置在与输入轴39较近的位置处，并且在转矩限制机构62与输入轴39之间的惯性力矩被大幅度地减小，因此也抑制了共振时所产生的过量转矩。
如上所述，根据本实施例，由于弧形弹簧结构的螺旋弹簧52被配置在外周侧，因此能够大幅度地降低螺旋弹簧52的弹簧刚性。并且，由于在螺旋弹簧52与转矩限制机构62之间追加设置有惯性板56，因此减震器装置38的惯性会增加。由此，能够实现螺旋弹簧52的弹簧刚性的减小与惯性的增加，其结果为，能够实现可回避扭转共振的NV衰减特性较高的减震器装置38。此外，虽然作为使惯性增加而导致的反效果，行驶中的施加于输入轴39上的载荷将变大，但通过使由曲轴36经由球轴承57而承受该载荷，从而能够防止随着惯性的增加而引起的输入轴39与外壳42的大型化。
此外，根据本实施例，转矩限制机构62被设置于与螺旋弹簧52相比靠径向的内侧且在轴向上不与该螺旋弹簧52重复的位置处。以此方式，由于利用螺旋弹簧52而被形成的鼓出部分与利用副板部58b以及转矩限制机构62而被形成的鼓出部分，以在径向上成为模具镶块的方式被配置，因此能够使螺旋弹簧52与转矩限制机构62之间的轴向的距离缩短从而能够缩短减震器装置38的轴向上的长度。
此外，根据本实施例，由于螺旋弹簧52通过弧形弹簧结构的弹簧而被构成，因此能够大幅度地减小螺旋弹簧52的弹簧刚性。
接下来，对本发明的其他的实施例进行说明。另外，在以下的说明中对于与前文所述的实施例共同的部分附加相同的符号并省略其说明。
实施例2
图3为用于对作为本发明的其他的实施例的减震器装置100的结构进行说明的剖视图。减震器装置100被配置于隔着作为外壳42的一部分的隔壁101而在轴向上与第一电动机MG1相邻的位置处。减震器装置100被构成为，包括：第一圆板102，其被连结在曲轴36上；环状的支承部件104，其与第一圆板102一起被连结在曲轴36上；螺旋弹簧106，其以被第一圆板102的外周部覆盖的方式而被收纳；第二圆板108，其经由螺旋弹簧106而以能够实施动力传递的方式被连结在第一圆板102上；惯性板110，其被连结在第二圆板108的内周部上；球轴承112，其被插设于惯性板110与支承部件104之间；第三圆板114，其被连结在惯性板110的外周部上；轴套116，其内周部通过花键嵌合而与动力传递装置12的输入轴39连结；转矩限制机构120，其被设置于第三圆板114与轴套116之间；球轴承134，其被插设于轴套116与支承部件104之间。另外，第一圆板102对应于本发明的第一板，第二圆板108对应于本发明的第二板，第三圆板114对应于本发明的第三板，轴套116对应于本发明的第四板，惯性板110对应于本发明的惯性体，螺旋弹簧106对应于本发明的弹性体，球轴承112对应于本发明的轴承，球轴承134对应于本发明的第二轴承。
第一圆板102的内周部通过螺栓122而与支承部件104一起被连接在曲轴36上，从而所述第一圆板102与发动机24一起以旋转轴心C为中心而一体地旋转。第一圆板102由圆盘状的主板部102a与圆盘状的副板部102b构成，所述圆盘状的主板部102a的内周部与曲轴36结合，所述圆盘状的副板部102b的外周部通过焊接而与主板部102a的外周部连接。主板部102a的外周部以在轴向上朝向发动机24侧而鼓出为碗状的方式而形成。此外，副板部102b的外周部以在轴向上朝向动力传递装置12而鼓出为碗状的方式而形成。而且，通过使主板部102a的外周端部与副板部102b的外周端部被相互焊接，从而在第一圆板102的外周部处形成了用于收纳螺旋弹簧106的截面大致为圆形的空间。
螺旋弹簧106被收纳于在第一圆板102的外周部处所形成的所述空间内，并且在第一圆板102与第二圆板108之间发生弹性形变且传递动力。另外，与前文所述的实施例相同地，螺旋弹簧106由弧形弹簧结构的两个第一弹簧106a以及弧形弹簧结构的两个第二弹簧106b构成，并且使用了低弹簧刚性的弹簧。
第二圆板108呈圆板形状，并且在轴向上被配置于在第一圆板102的主板部102a与副板部102b之间所形成的间隙中。在第二圆板108的外周部处形成有两个两个半圆状的空间，并且在该空间中分别收纳有螺旋弹簧106。此外，第二圆板108的内周部通过铆钉124而与惯性板110的内周部连结。
惯性板110呈具有预定厚度的圆盘形状，并被设置在螺旋弹簧106与转矩限制机构120之间的动力传递路径上。惯性板110的内周部通过铆钉124而与第二圆板108连接。此外，惯性板110的内周端部被配置于在径向上与支承部件104重复的位置处，在惯性板110的内周端部与支承部件104之间插设有球轴承112。以惯性板110的外周部位于与内周部相比在轴向上靠动力传递装置12侧的方式使惯性板110的径向上的一部分发生变形。在相对于惯性板110的内周部而在径向的外侧处形成有空间，并且在该空间中配置有副板部102b的内周部。即，惯性板110的内周部与副板部102b的内周部在径向上一部分重复。此外，惯性板110的外周部被收纳于在与副板部102b的于轴向上鼓出的部位相比靠内周侧处所形成的空间中。即，惯性板110的外周部与副板部102b的于轴向上鼓出的部位在径向上一部分重复。
惯性板110的外周部通过螺栓126而与第三圆板114连接。第三圆板114由圆盘形状的主板部114a以及圆盘形状的副板部114b这两个板构成。主板部114a的外周部与副板部114b的外周部通过利用铆钉128而被结合在一起从而被一体地构成。此外，这些主板部114a以及副板部114b在于径向上与第一电动机MG1的线圈端130以及螺旋弹簧106相比靠内周侧的位置处，通过螺栓126而与惯性板110的外周部结合在一起。第三圆板114的外周部被延伸设置至在轴向上与螺旋弹簧106以及第一电动机MG的线圈端130重复的位置处，并且惯性质量被确保与第三圆板114在径向上被延伸设置的量对应的部分。
主板部104a的内周部以在轴向上向第一电动机MG1鼓出的方式而被弯曲。此外，副板部104b的内周部以在轴向上向发动机24侧鼓出的方式沿着惯性板110的壁面而被弯曲。而且，在形成于该主板部104a的内周部与副板部104b的内周部之间的间隙中收纳有转矩限制机构120。另外，由于转矩限制机构120的具体的结构与前文所述的实施例的转矩限制机构62大致相同，因此省略其说明。
在本实施例中，转矩限制机构120被设置于与螺旋弹簧106相比靠径向内侧且在轴向上不与螺旋弹簧106重复的位置处。并且，本实施例的转矩限制机构120被设置于与第一电动机MG1的线圈端130相比靠径向内侧且在轴向上不与线圈端130重复的位置处。
如图3所示，转矩限制机构120被配置于在径向上与螺旋弹簧106以及线圈端130相比靠内侧处。即，转矩限制机构120被配置于不会与线圈端130(以及隔壁101)的鼓出部分以及副板部102b(以及螺旋弹簧106)的鼓出部分发生干涉的位置处。具体而言，在通过线圈端130(以及隔壁101)的鼓出而被形成的该线圈端130的内周侧的空间，以及通过副板部102b(以及螺旋弹簧106)的鼓出而被形成的该副板部102b的内周侧的空间中配置转矩限制机构120。更加具体而言，转矩限制机构120以及对该转矩限制机构120进行覆盖的主板部114a相对于线圈端130(以及隔壁101)的鼓出部分而向线圈端130侧鼓出。也就是说，成为如下的结构，即，转矩限制机构120(以及主板部114a)的鼓出部分配置于线圈端130(以及隔壁101)的鼓出部分的内周侧的模具镶块结构。此外，转矩限制机构120以及对该转矩限制机构120进行覆盖的副板部114b相对于副板部102b(以及螺旋弹簧106)的鼓出部分而向副板部102b侧鼓出。也就是说，成为如下的结构，即，转矩限制机构120(以及副板部114b)的鼓出部分被配置于副板部102b(以及螺旋弹簧106)的鼓出部分的内周侧的模具镶块结构。
此外，转矩限制机构120的线板与轴套116通过铆钉132而被结合。轴套116由圆筒形状的筒部116a、和从该筒部116a向径向延伸的凸缘部116b构成。由于筒部116a的内周部与输入轴39花键嵌合，从而被设为相对于输入轴39而无法相对旋转。在筒部116a的轴向上于发动机24侧的外周端部与支承部件104之间被插设有球轴承134。此外，凸缘部116b的外周部通过铆钉132而与转矩限制机构120的线板结合在一起。
由于在以上述方式而构成的减震器装置100中，在螺旋弹簧106与转矩限制机构120之间设置有惯性板110，因此相对于减震器装置100的螺旋弹簧106而输入轴39侧的惯性质量会增加。此外，由于即使在减震器装置100中也使用了弧形弹簧结构的螺旋弹簧106，因此能够大幅度地减小弹簧刚性。因此，能够大幅度地减小驱动系统的共振频率区域，从而能够防止发动机的常用转速区域中所产生的扭转共振。
在此，作为设置惯性板110所导致的反效果，施加于车辆行驶中的输入轴39上的载荷也会增大。相对于此，由于在惯性板110的内周端部与支承部件104之间插设有球轴承112，因此曲轴36会经由球轴承112而承受载荷，从而施加于输入轴39上的载荷将会减小。而且，在本实施例中，由于在支承部件104与轴套116(圆筒部116a)之间也插设有球轴承134，因此曲轴36会经由球轴承134而承受施加于轴套116上的载荷。因此，施加于输入轴39上的载荷会减小。
如上所述，在本实施例中也能够取得与前文所述的实施例相同的效果。此外，在本实施例中，转矩限制机构120被设置于与第一电动机MG1的线圈端130相比靠内侧且在轴向上不与线圈端130重复的位置处。以此方式，能够通过将转矩限制机构120配置于在第一电动机MG1的线圈端130的内周侧所形成的空间内，并设为将转矩限制机构120的鼓出部分配置于线圈端130的鼓出部分的内周侧的模具镶块结构，从而能够将动力传递装置12的轴向上的长度缩短。
此外，通过将球轴承134插设于轴套116与支承部件104之间，从而能够使曲轴36经由球轴承134而承受轴套116的载荷。因此，由于施加于输入轴39上的载荷减小，因此能够防止输入轴39和外壳42的大型化。
以上，虽然根据附图来对本发明的实施例进行了详细地说明，但本发明也适用于其他的方式。
例如，虽然前文所述的各实施例为各自独立的方式，也可以适当地进行组合而实施。例如也可以在减震器装置38中，在轴套60与支承部件51之间设置轴承。
此外，虽然在前文所述的实施例中，将第一圆板50与支承部件51分体设置，但也可以使第一圆板50与支承部件51一体成形。
此外，虽然在前文所述的实施例中，转矩限制机构120被设置于与螺旋弹簧106相比靠径向的内侧且在轴向上不与螺旋弹簧106重复的位置处，但转矩限制机构120也可以为仅满足被设置于第一电动机MG1的线圈端130的内侧且在轴向上不与线圈端130重复的位置处的主要部件的结构。
此外，虽然在前文所述的实施例中，螺旋弹簧52、106具有弧形弹簧结构，但并不限定于此，也可以使用现有技术中的螺旋弹簧。
此外，虽然在前文所述的实施例中，摩擦部件80被设为粘贴于线板74侧，但也可以将其粘贴于板部58a或压板76侧。此外，摩擦部件80也可以通过粘贴以外的方法被固定在线板74或压板76上。
此外，虽然在前文所述的实施例中使用了球轴承57、112、134，但并不限定于球轴承，例如也可以使用滚子轴承等其他形式的轴承。
此外，虽然在前文所述的实施例中使用了两个螺旋弹簧52，但并不限定于两个，也可以为三个以上。
此外，虽然在前文所述的实施例中，减震器装置38、100被应用于具备了由行星齿轮装置26构成的差动机构的混合动力车辆中，但并不限定于具备了差动机构的混合动力车辆中，也可以采用如下的结构，即，发动机与电动机不经由差动机构，而直接或经由离合器等而被连结的结构。此外，并不限定于混合动力车辆。
另外，上述内容只是一个实施方式，本发明能够基于本领域技术人员的知识而以追加了各种改变、改良的方式来实施。
