Description
技术领域
本发明涉及在例如汽车用内燃机中为了控制吸气阀或排气阀的开闭时机而装备的阀正时控制装置。
背景技术
在专利文献1、2中,公开了一种阀正时控制装置,该阀正时控制装置具有:与内燃机的曲柄轴同步旋转的驱动侧旋转体;配置于上述驱动侧旋转体的内侧且相对于该驱动侧旋转体能够以同轴心的方式相对旋转的从动侧旋转体;以与上述从动侧旋转体同轴心方式配置于上述从动侧旋转体和上述内燃机的阀开闭用凸轮轴之间的转接器;以与上述凸轮轴同轴心方式配置,并将上述从动侧旋转体和上述凸轮轴以夹着上述转接器的状态紧固成一体的螺钉部件;以及能够改变上述驱动侧旋转体和上述从动侧旋转体之间的相对旋转相位的相位变更机构。
专利文献
专利文献1:德国专利申请公开第102008057492号说明书
专利文献2:日本特开第2012-172559号公报
发明内容
在从动侧旋转体的旋转轴心和凸轮轴的旋转轴心一致的精度(同轴精度)较低的情况下,可能会对阀正时控制装置的工作带来障碍。
专利文献1的阀正时控制装置中,通过外嵌于螺钉部件的转接器使从动侧旋转体以同轴心的方式组装于凸轮轴。
因此,从动侧旋转体和凸轮轴的同轴精度依赖于从动侧旋转体对转接器的组装精度和转接器对螺钉部件的组装精度,而这些组装精度互相关联,因此难以提高同轴精度。
专利文献2的阀正时控制装置中,将转接器压入从动侧旋转体的内周侧而组装成一体,并通过螺钉部件将该组装成一体的从动侧旋转体和转接器紧固于凸轮轴,从而使从动侧旋转体以同轴心的方式组装于凸轮轴。
因此,从动侧旋转体和凸轮轴的同轴精度依赖于从动侧旋转体对转接器的组装精度和组装成一体的从动侧旋转体和转接器的基于螺钉部件的对凸轮轴的组装精度,而这些组装精度也互相关联,因此难以提高同轴精度。
本发明是鉴于上述实际情况而完成的,希望提供一种容易谋求提高从动侧旋转体和凸轮轴的同轴精度的阀正时控制装置。
本发明所涉及的阀正时控制装置的特征结构在于,具有驱动侧旋转体、从动侧旋转体、转接器、固定部件和相位变更机构。上述驱动侧旋转体与内燃机的曲柄轴同步旋转;上述从动侧旋转体配置在上述驱动侧旋转体的内侧且相对于上述驱动侧旋转体能够以同轴心的方式相对旋转;上述转接器以与上述从动侧旋转体同轴心的方式配置于上述从动侧旋转体和上述内燃机的阀开闭用凸轮轴之间;上述固定部件以与上述凸轮轴同轴心的方式配置且将上述从动侧旋转体和上述凸轮轴以夹着上述转接器的状态固定成一体;上述相位变更机构能够改变使上述驱动侧旋转体和上述从动侧旋转体之间的相对旋转相位。上述从动侧旋转体具有以同轴心的方式压接于上述固定部件的部分,并且上述从动侧旋转体固定成其与上述转接器之间在径向上设置有间隙。上述从动侧旋转体具有以同轴心的方式压接于上述固定部件的部分,并且上述从动侧旋转体固定成其与上述转接器之间在径向上设置有间隙。
本结构的阀正时控制装置中,从动侧旋转体具有以同轴心的方式压接于固定部件的部分,并且上述从动侧旋转体固定成其与转接器在径向上设置有间隙。
因此,与转接器对固定部件或凸轮轴的组装精度无关地,能够根据从动侧旋转体对固定部件的组装精度来设定从动侧旋转体和凸轮轴的同轴精度。
因此,本结构的阀正时控制装置中,容易提高从动侧旋转体和凸轮轴的同轴精度。
本发明的其他特征结构在于,横跨上述从动侧旋转体和上述转接器设置有能够限制上述从动侧旋转体和上述转接器之间的相对旋转的相对旋转限制部。
在上述结构中,通过限制从动侧旋转体和转接器之间的相对旋转,能够使转接器和驱动侧旋转体的相对旋转变得稳定。并且,在对准彼此的相位而组装从动侧旋转体和转接器时非常方便。
即,在将固定部件穿过从动侧旋转体和转接器之前,并不防止两者沿径向相对移动。由此,能够提高将固定部件穿过以在径向上存在间隙的方式组装的从动侧旋转体和转接器时的组装性,并且在组装之后,能够将从动侧旋转体和转接器之间的相对旋转相位设定为规定的相位。
本发明的其他特征结构在于,上述相对旋转限制部具备:销部件以及凹部,上述销部件固定于上述从动侧旋转体及上述转接器中的任一设置于上述从动侧旋转体及上述转接器中的另一方,并且上述销部件沿上述凸轮轴的长度方向***于上述凹部;上述凹部形成为在上述凹部和上述销部件之间沿上述径向形成有间隙的长孔状。
在本结构中,通过将销部件卡入凹部的简单的构造,就能够限制从动侧旋转体和转接器的相对旋转。
本发明的其他特征结构在于,上述从动侧旋转体由铝材制成,上述转接器由钢材制成,上述销部件固定于上述转接器,上述凹部设置于上述从动侧旋转体。
在本结构中,由于将杆部件固定于钢制的转接器,因此相对于杆部件的转接器的固定难以产生松动,并且由于能够长期对从动侧旋转体和转接器的相对旋转进行限制,从而能够高精度地控制阀开闭时机。
本发明的其他结构特征在于,上述转接器与上述固定部件嵌合。
在本结构中,转接器也能够独立于从动侧旋转体而以同轴心的方式组装于凸轮轴,因此能够提高被转接器所支承的驱动侧旋转体的旋转精度。其结果,能够使驱动侧旋转体和从动侧旋转体顺畅地相对旋转。

具体实施方式
下面参照附图,对本发明的实施方式进行说明。
图1~图2表示装备于汽车用发动机(内燃机的一个例子)的本发明所涉及的阀正时控制装置。
阀正时控制装置具有:与发动机E的曲柄轴101同步旋转的钢制外壳(驱动侧旋转体)1;配置于外壳1的内侧且相对于该外壳1能够以同轴心X的方式相对旋转,并且与发动机的阀开闭用凸轮轴102同步旋转的铝合金制内部转子(从动侧旋转体)2;以与内部转子2同轴心X的方式配置在内部转子2和凸轮轴102的端部之间,并在外周侧具有能够相对旋转自如地支承外壳1的支承面3a的圆筒状的钢制转接器3;能够改变外壳1和内部转子2之间的相对旋转相位的相位变更机构4;以及在发动机停止时将外壳1和内部转子2之间的相对旋转相位限制为最大滞后角相位的锁定机构5。
外壳1为通过将配置于与凸轮轴102的存在侧相反的一侧的前板1a、覆盖内部转子2的外部转子1b、一体地具有定时链轮1d的后板1c一体地组装而构成。
通过在外部转子1b的内周侧沿围绕旋转轴心X的方向隔开间隔而形成多个突出部6,从而在内部转子2和外部转子1b之间形成流体压室7。
在内部转子2的外周部中的面对流体压室7的部分形成有将流体压室7分隔为提前角室7a和滞后角室7b的分隔部8。
相位变更机构4设置成向提前角室7a或滞后角室7b中的一方供给油(工作流体)的同时使油从另一方排出,从而能够改变相对旋转相位。
通过将以同轴心X的方式内嵌于内部转子2和转接器3中的钢制的OCV螺栓9螺纹固定于凸轮轴102的端部,将内部转子2和转接器3组装于凸轮轴102并使其以同轴心X的方式与凸轮轴102一体地旋转。
OCV螺栓9相当于以与凸轮轴102同轴心X的方式配置且能够将内部转子2和凸轮轴102以夹着转接器3的状态紧固成一体的螺钉部件等固定部件。
内部转子2和转接器3分别具有相对于OCV螺栓9以同轴心的方式压接的部分,并且以相对于OCV螺栓9的外周面沿径向无法移动而沿轴心X方向能够移动的方式分别外嵌固定于OCV螺栓9。
由于转接器3外嵌固定于OCV螺栓9并且以同轴心X的方式组装于凸轮轴102,因此提高了被转接器3所支承的外壳1的旋转精度。
另外,内部转子2和转接器3也可以外嵌固定成相对于OCV螺栓9的外周面沿径向和轴心X方向均无法移动。
凸轮轴102的端部与形成于转接器3的端部的圆筒状的凹面部3b以同轴心X方式嵌合。
转接器3具有形成支承面3a的小径部3c和发挥防止从后板1c脱落的功能的大径部3d。在将大径部3d放入形成于内部转子2的端部的圆筒状的凹面部2a中的情况下,在凹面部2a和大直径部3d的外周面之间设有间隙10,以使内部转子2在旋转径向上不与转接器3抵接。
遍及内部转子2和转接器3而设有能够限制内部转子2和转接器3的相对旋转的相对旋转限制部11。
相对旋转限制部11如下构成:将圆柱状的销部件11a以销的轴心与旋转轴心X平行的姿势固定于转接器3,同时将杆部件11a在仅允许沿旋转直径方向移动的状态下卡入的凹部11b设于内部转子2而构成。在内部转子2设置使销部件11a卡入且允许销部件11a仅向旋转径向移动的凹部11b。
凹部11b形成为沿旋转半径方向较长的长孔状。如果销部件11a沿凸轮轴102的长度方向***于凹部11b,则在凹部11b和销部件11a之间在径向上形成有间隙11c。
因此,在将OCV螺栓9穿过内部转子2和转接器3时,能够使内部转子2和转接器3沿旋转径向相对移动以使其成为同心从而提高组装性,并且能够将组装OCV螺栓9后的内部转子2和转接器3的相对旋转相位设定为规定的相位。
在内部转子2的内周面设有:用于在内部转子2的内周面与OCV螺栓9的外周面之间形成经由提前角油路12a与提前角室7a连通的提前角用环状油路12的周向槽、用于在内部转子2的内周面与OCV螺栓9的外周面之间形成与连接于油泵的供给油路13a连通的供给用环状油路13的周向槽。
在转接器3的内周面设有:用于形成经由滞后角油路14a与滞后角室7b连通的滞后角用环状油路14的周向槽、用于在转接器3的内周面与OCV螺栓9的外周面之间形成中继用环状油路15的周向槽,该中继用环状油路15以使供给油路13a和供给用环状油路13连通的方式而进行转接。
提前角油路12a设置成针对各提前角室7a沿径向贯穿内部转子2。滞后角油路14a针对各滞后角室7b遍及转接器3的大径部3d和内部转子2而形成。
滞后角用环状油路14沿着转接器3的内周侧角部而设置成面向OCV螺栓9的外周面和凹面部2a的底面。
隔开滞后角用环状油路14的靠近凸轮轴102的一侧的槽侧面14b形成为随着靠近OCV螺栓9而靠近凸轮轴102侧的圆锥面状。
由此,在将OCV螺栓9内嵌于内部转子2和转接器3时,即使转接器3的轴心相对于旋转轴心X偏心,OCV螺栓9也难以卡在用于形成滞后角用环状油路14的周向槽部分。
如图1所示,凸轮轴102为使吸气阀103开闭的凸轮104的旋转轴,其与OCV螺栓9、内部转子2和转接器3同步旋转。凸轮轴102旋转自如地支承于发动机的未图示的气缸盖。
如果曲柄轴101旋转驱动,则旋转动力经由动力传递部件105传递至定时链轮1d,从而使外壳1沿图2所示的旋转方向S旋转驱动。
随着外壳1的旋转驱动,内部转子2沿旋转方向S从动旋转从而使凸轮轴102旋转,设置于凸轮轴102的凸轮104下压吸气阀103以使其开阀。遍及内部转子2和后板1c安装有扭力盘簧16,该扭力盘簧16使内部转子2相对于外壳1的旋转相位趋向提前角方向S1。
如图2所示,提前角方向S1为提前角室7a的容积增大的方向,滞后角方向S2为滞后角室7b的容积增大的方向。提前角室7a的容积成为最大时的相对旋转相位为最大提前角相位,滞后角室7b的容积成为最大时的相对旋转相位为最大滞后角相位。
相位变更机构4通过螺线管4a的工作使安装于OCV螺栓9的内侧的卷轴17移动,从而控制相对于提前角室7a及滞后角室7b的油的供给、排出、或者切断该供排,使相对旋转相位改变为提前角方向或者滞后角方向,或者,保持在所希望的相对旋转相位。
锁定机构5具有:以能够朝向外壳1并沿旋转轴心X的方向进出的方式安装于内部转子2的锁定部件5a、形成于外壳1的锁定凹部、供给锁定解除用的油的锁定解除油路5c。
锁定解除油路5c与提前角用环状油路12连通。
锁定机构5在发动机停止工作时通过弹簧等施力部件的作用力使锁定部件5a与锁定凹部5b嵌合,从而将外壳1和内部转子2的相对旋转相位限制为最大滞后角相位。
而且,如果为了使相对旋转相位向提前角方向S1发生变更而向提前角用环状油路12供给油,则油经由锁定解除油路5c而被供给至锁定凹部5b,使锁定部件5a抵抗作用力从锁定凹部5b退出从而解除锁定。
