具体实施方式
以下,参照附图对本实施方式所涉及的动力传递装置进行说明。需要说明的是,在以下的说明中,轴向是动力传递装置的旋转轴O延伸的方向。另外,周向是以旋转轴O为中心的圆的周向,径向是以旋转轴O为中心的圆的径向。另外,在本实施方式中,轴向的第一侧是指图1和图2的左侧,轴向的第二侧是指图1和图2的右侧。
如图1和图2所示,动力传递装置100具备柔性飞轮10、阻尼装置50(转矩传递部件的一例)、多个第一螺栓11、多个第二螺栓12以及多个定位销13。动力传递装置100例如配置于从发动机或电动机等驱动源到驱动轮的动力传递路径内。例如,驱动源相对于动力传递装置100配置于轴向的第一侧,变速机等相对于动力传递装置100配置于轴向的第二侧。
动力传递装置100安装于第一传递轴和第二传递轴,以将来自驱动源侧的第一传递轴(省略图示)的动力传递到驱动轮侧的第二传递轴(省略图示)。第一传递轴和第二传递轴在同轴上配置。第一传递轴例如是曲轴。第二传递轴例如是变速器的输入轴。柔性飞轮10安装于第一传递轴,阻尼装置50安装于第二传递轴。
[柔性飞轮]
柔性飞轮10具有惯性环2和柔性板3(板的一例)。另外,柔性飞轮10具有碟形弹簧4。
惯性环2为环状。惯性环2具有多个第一贯通孔21和多个第二贯通孔22。各第一贯通孔21和各第二贯通孔22沿轴向贯通惯性环2。
各第一贯通孔21和各第二贯通孔22配置于同一圆周上。即,各第一贯通孔21的P.C.D(Pitch Circle Diameter:节圆直径)与各第二贯通孔22的P.C.D相同。各第一贯通孔21和各第二贯通孔22在周向上相互隔开间隔地配置。
如图1所示,第一贯通孔21沿轴向延伸。第一贯通孔21在轴向的第一侧开口,并且也在轴向的第二侧开口。第一贯通孔21在轴向上具有遍及整个轴向的内螺纹部。即,第一贯通孔21遍及轴向的整体而构成螺纹孔。
如图2所示,第二贯通孔22沿轴向延伸。第二贯通孔22在轴向的第一侧开口,并且也在轴向的第二侧开口。第二贯通孔22具有第一孔部221和第二孔部222。
第一孔部221是第二贯通孔22中的配置于轴向的第一侧的部分。第一孔部221具有内螺纹部。即,第一孔部221构成螺纹孔。
第二孔部222是第二贯通孔22中的配置于轴向的第二侧的部分。第二孔部222的直径大于第一孔部221的直径。因此,在第二孔部222与第一孔部221之间形成有台阶部223。需要说明的是,第二孔部222和第一孔部221在同轴上配置。
第二孔部222不具有内螺纹部。即,第二孔部222不构成螺纹孔。
如图1和图2所示,柔性板3在轴向上相对于惯性环2配置于第一侧。柔性板3为圆板状,在中央具有开口部。柔性板3的外径小于惯性环2的外径。
柔性板3在其内周部安装有第一传递轴。动力经由该第一传递轴从发动机、电动机等驱动源传递至柔性板3。柔性板3能够弹性变形。因此,柔性板3能够吸收来自第一传递轴的振动。
柔性板3在其外周部安装于惯性环2。柔性板3通过多个第一螺栓11安装于惯性环2。
详细而言,柔性板3具有多个第三贯通孔31。各第三贯通孔31在同一圆周上相互隔开间隔地配置。各第三贯通孔31的P.C.D与各第一贯通孔21的P.C.D相同。
第一螺栓11从轴向的第一侧贯通第三贯通孔31,并与第一贯通孔21或第二贯通孔22螺纹连接。由此,第一螺栓11将柔性板3紧固于惯性环2。
碟形弹簧4在轴向上配置于惯性环2与柔性板3之间。碟形弹簧4的外周端部与惯性环2的内周端部抵接。碟形弹簧4的内周端部与柔性板3抵接。
[阻尼装置]
阻尼装置50在轴向上相对于惯性环2配置于第二侧。阻尼装置50在其外周部安装于惯性环2。阻尼装置50通过多个第二螺栓12安装于惯性环2。阻尼装置50构成为从惯性环2被传递转矩。
详细而言,阻尼装置50具有多个第四贯通孔54和第五贯通孔55。各第四贯通孔54在同一圆周上相互隔开间隔地配置。各第四贯通孔54的P.C.D与各第二贯通孔22的P.C.D相同。即,各第四贯通孔54的P.C.D与各第三贯通孔31的P.C.D相同。
如图2所示,定位销13嵌合于该第四贯通孔54,并且也嵌合于第二贯通孔22的第二孔部222。这样,通过使定位销13嵌合于第四贯通孔54和第二贯通孔22,从而进行阻尼装置50在周向上的定位。需要说明的是,通过台阶部223限制定位销13向第一孔部221的侵入。
如图1所示,各第五贯通孔55在同一圆周上相互隔开间隔地配置。各第五贯通孔55和各第四贯通孔54配置在同一圆周上。各第五贯通孔55的P.C.D与各第一贯通孔21的P.C.D相同。即,各第五贯通孔55的P.C.D与各第三贯通孔31的P.C.D相同。
第二螺栓12从轴向的第二侧贯通第五贯通孔55,并与第一贯通孔21螺纹连接。由此,第二螺栓12将阻尼装置50紧固于惯性环2。需要说明的是,第一螺栓11的前端与第二螺栓12的前端不接触。即,第一螺栓11和第二螺栓12在轴向上具有间隔。
这样,在将阻尼装置50安装于惯性环2时,多个第二螺栓12全部与第一贯通孔21螺纹连接,而不与第二贯通孔22螺纹连接。在第二贯通孔22中嵌合有定位销13,以代替第二螺栓12的螺纹连接。另一方面,在将柔性板3安装于惯性环2时,多个第一螺栓11中的几个与第一贯通孔21螺纹连接,而剩余的第一螺栓11与第二贯通孔22螺纹连接。第二螺栓12与定位销13的合计数量与第一螺栓11的数量相等。即,第一螺栓11比第二螺栓12多。
阻尼装置50具有阻尼单元5和转矩限制器单元6。
阻尼单元5具有第一输入板51、第二输入板52、轮毂凸缘53以及多个弹性部件56。另外,阻尼单元5具有迟滞产生机构57。阻尼单元5构成为对旋转变动进行衰减。
第一输入板51和第二输入板52通过铆钉58相互固定,并一体地旋转。第一输入板51和第二输入板52具有窗部511、521。弹性部件56由该窗部511、521支承。
轮毂凸缘53构成为将来自第一输入板51和第二输入板52的转矩传递到输出侧的装置。轮毂凸缘53具有轮毂531和凸缘板532。轮毂531和凸缘板532通过多个齿以及与该齿啮合的多个凹部而成为一体化。
轮毂531是形成有花键孔的筒状部件。第二传递轴能够与该花键孔花键卡合。
凸缘板532在轴向上配置于第一输入板51与第二输入板52之间。凸缘板532具有收容孔533。在该收容孔533内收容有弹性部件56。
弹性部件56构成为在旋转方向上弹性地连结第一输入板51、第二输入板52与凸缘板532。弹性部件56例如是螺旋弹簧。
[转矩限制器单元]
转矩限制器单元6相对于阻尼单元5配置于径向外侧。转矩限制器单元6构成为对在柔性飞轮10与阻尼单元5之间传递的转矩进行限制。
转矩限制器单元6具有第一侧板61、第二侧板62、压板63、锥形弹簧64以及摩擦盘65。
第一侧板61和第二侧板62为环状。第一侧板61和第二侧板62通过铆钉66等相互固定。因此,第一侧板61和第二侧板62相互一体地旋转。在该第一侧板61和第二侧板62的外周部形成有多个第四贯通孔54和多个第五贯通孔55。
压板63为环状。压板63在轴向上配置于第一侧板61与第二侧板62之间。锥形弹簧64在轴向上配置于第二侧板62与压板63之间。锥形弹簧64对压板63朝向第一侧板61施力。
摩擦盘65具有芯板651和一对摩擦部件652。摩擦盘65在其内周端部安装于第一输入板51。锥形弹簧64经由压板63将摩擦盘65按压到第一侧板61。
当从惯性环2向第一侧板61输入规定值以上的转矩时,摩擦盘65在第一侧板61上滑动,摩擦盘65与第一侧板61相对旋转。
[变形例]
以上,对本发明的实施方式进行了说明,但本发明并不限定于此,只要不脱离本发明的主旨,就能够进行各种变更。
变形例1
在上述实施方式中,在惯性环2上形成有第一贯通孔21和第二贯通孔22这两种贯通孔,但惯性环2的结构并不限定于此。例如,也可以在惯性环2上仅形成第一贯通孔21,而不形成第二贯通孔22。
在这种情况下,能够使第一螺栓11的数量与第二螺栓12的数量相同。另外,也可以在惯性环2上形成定位销13用的多个凹部。定位销13用的各凹部的P.C.D可以与各第一贯通孔21的P.C.D相同,也可以不同。
变形例2
在上述实施方式中,阻尼装置50具有转矩限制器单元6,但也可以不具有转矩限制器单元6。在这种情况下,在阻尼单元5的第一输入板51和第二输入板52中的至少一方的外周部上形成有第四贯通孔54和第五贯通孔55。并且,第一输入板51和第二输入板52中的至少一方通过第二螺栓12紧固于惯性环2。
