Description

用于车辆的车轮驱动装置
技术领域
本发明涉及一种用于车辆的车轮驱动装置,特别地,涉及一种用于车辆的车轮驱动装置,该车轮驱动装置的内部部件可以在损坏时被分离以进行更换和修理。
背景技术
通常,汽车动力传动系是一种将来自发动机的动力传递到驱动轮的系统,在该系统中,来自发动机的动力被转换成速度和扭矩后被传递到与轮轴连接的差速器。因此,轮轴通过差速器旋转并且连接到轮轴的端部的驱动轮旋转,从而驱动车辆。
特别地,万向节被联接到用于传递动力的驱动轴,并且该万向节是用于将动力传递到以不同角度布置的旋转轴的部件。对于动力传递角度较小的推力轴,使用钩形万向节、柔性万向节,对于动力传递角度大的前轮驱动车辆的驱动轴,使用等速万向节。
等速万向节是应用到前轮驱动车辆的驱动轴的部件,即使通过前轮转向而改变动力传递的角度,该等速万向节也能够在不出现旋转不平衡的情况下快速地驱动前轮。
根据现有技术的等速万向节的连接结构,内圈和等速轴通过弹性挡圈被轴向固定。然而,设置等速万向节的轮毂壳体的内部被密封以防止等速万向节内部的润滑油泄漏到外部。由于轮毂壳体的内部被密封,因此难以分离固定内圈和等速轴的弹性挡圈。
因此,需要强制地施加力以分离等速万向节,因而部件可能被损坏并且分离操作非常困难。
前述内容仅旨在帮助理解本发明的背景,而不旨在表示本发明落入本领域技术人员已知的现有技术的范围内。
发明内容
本发明旨在解决上述问题并且本发明的目的是提供一种用于车辆的车轮驱动装置,该车轮驱动装置能够使作为内部部件的等速万向节容易地分离以用于更换和修理。
为了实现本发明的目的,用于车辆的车轮驱动装置包括:连接构件,可分离地联接到等速万向节,并且当连接构件被安装在等速万向节上时,连接构件将轴承固定到等速万向节;轮毂壳体,具有空的内部并且等速万向节通过轴承被联接在轮毂壳体的内部;以及轮毂盖,可分离地设置在轮毂壳体的内部,当被联接到轮毂壳体时密封轮毂壳体的内部,并且当与轮毂壳体分离时允许连接构件被分离或被安装。
固定槽可以围绕等速万向节的第一端形成,并且连接构件可以以环的形状装配在固定槽中。
安装轴承的轴承座可以被形成在等速万向节的端部,固定槽可以被形成在轴承座的第一端,并且固定突起可以围绕轴承座的第二端形成,从而轴承可以被设置并固定在连接构件与固定突起之间。
轴承可以由装配在等速万向节上的内圈、装配在轮毂壳体的内周表面上的外圈和容纳在内圈与外圈之间的滚珠构成,并且内圈可以被设置在连接构件与固定突起之间并且可以在等速万向节的轴向上位置被固定。
连接构件可以是在两端部具有孔的卡环。
螺纹可以围绕轮毂壳体的内部的内周表面形成并且与轮毂壳体的螺纹对应的螺纹可以被形成在轮毂盖的外周表面上。
直的紧固槽可以被形成在轮毂盖的侧面上。
根据具有上述结构的用于车辆的车轮驱动装置,由于轮毂壳体的内部可以被打开和关闭,因此作为车轮驱动装置的内部部件的等速万向节在必要时可以被分离。由于等速万向节可以以该方式被更换和修理,因此能够持续维护并且可以保证耐久性。
附图说明
根据以下结合附图的具体实施方式,本发明的以上和其它目的、特征及其它优点将被更清楚地理解,其中:
图1是示出根据本发明的实施例的用于车辆的车轮驱动装置的视图;
图2和图3是示出图1所示的用于车辆的车轮驱动装置的视图;以及
图4是示出现有技术的车轮驱动装置的视图。
具体实施方式
下面参照附图来描述根据实施例的用于车辆的车轮驱动装置。
图1是示出根据本发明的实施例的用于车辆的车轮驱动装置的视图,并且图2和图3是示出图1所示的用于车辆的车轮驱动装置的视图。图4是示出现有技术的车轮驱动装置的视图。
如图1和图2所示,根据本发明的用于车辆的车轮驱动装置包括:连接构件30,可分离地联接到等速万向节10,并且当连接构件30被安装在等速万向节10上时,连接构件30将轴承20固定到等速万向节10;轮毂壳体40,具有空的内部并且等速万向节10通过轴承20被联接在轮毂壳体40的内部;以及轮毂盖50,可分离地设置在轮毂壳体40的内部,当被联接到轮毂壳体40时密封轮毂壳体40的内部,并且当与轮毂壳体40分离时允许连接构件30被分离或被安装。
如上所述,等速万向节10和轮毂壳体40通过轴承20连接,并且轴承20通过连接构件30被固定而不在等速万向节10上轴向地移动。连接构件30可以是在两端部具有孔32的弹性挡圈或卡环。当工具被插入孔32中后,端部被强制地打开时,连接构件30的直径增大,从而连接构件30可以与等速万向节10分离,相反地,连接构件30可以被容易地装配并且限制轴承20的轴向移动。
特别地,在本发明中,轮毂盖50被可分离地设置在轮毂壳体40的内部。因此,当轮毂盖50被联接到轮毂壳体40时,轮毂壳体40的内部被密封,从而形成密封结构以防止润滑油泄漏到等速万向节10的外部。进一步地,联接到等速万向节10的连接构件30可以通过分离轮毂盖50从轮毂壳体40分离。
即,在现有技术中,如图4所示,轮毂壳体1的内部通过分离构件2被密封,分离构件2与轮毂壳体1一体地形成,从而分离构件2不能被分离。进一步地,等速万向节3和轴承4通过弹性挡圈5连接,但弹性挡圈5被装配在轴承4的内圈6的内侧上,因而一旦轴承4和等速万向节3通过弹性挡圈5彼此连接,则难以使部件之间分离。
如上所述,尽管在现有技术中部件之间被强力地彼此联接,但未考虑部件的后续维护,因此当部件损坏时,不得不更换整个装置。
本发明已解决该问题。轮毂盖50被可分离地设置在轮毂壳体40的内部,从而当轮毂盖50被安装在轮毂壳体40的内部时,能够防止润滑油的泄漏和异物的渗入。进一步地,当轮毂盖50被分离时,轮毂壳体40的内部被打开,从而能够将工具放入到打开的内部中并且将连接构件30与等速万向节10分离。
下面更详细地描述本发明。如图3所示,固定槽12围绕等速万向节10的第一端形成,并且连接构件30可以以环的形状装配在固定槽12中。
由于固定槽12形成在等速万向节10的第一端并且连接构件30被装配在固定槽12中,因此连接构件30可以在轮毂壳体40的内部被容易地联接和分离。
参照图1,等速万向节10紧固在轮毂壳体40的第二侧,并且轮毂盖50设置在轮毂壳体40的内部的中央处。当轮毂盖50与轮毂壳体40分离时,轮毂壳体40的内部被打开,从而能够从轮毂壳体40的第一侧将工具放入到轮毂壳体40的内部并且将连接构件30与等速万向节10分离。由于连接构件30被装配在形成在等速万向节10的第一端的固定槽12中,从而能够在轮毂壳体40的内部容易地分离装配在等速万向节10的第一端的连接构件30。
同时,如图1和图3所示,安装轴承20的轴承座14被形成在等速万向节10的端部,固定槽12围绕轴承座14的第一端形成,并且固定突起16围绕轴承座14的第二端形成,从而轴承20可以被设置并固定在连接构件30与固定突起16之间。
形成在等速万向节10上的轴承座14由多个齿构成并且安装在轴承座14上的轴承20也具有与轴承座14的齿对应的齿,从而轴承座14和轴承20可以彼此啮合。因此,当等速万向节10旋转时,与轴承座14啮合的轴承20也可以旋转。
特别地,固定槽12被形成在轴承座14的第一端并且固定突起16被形成在轴承座14的第二端。即,固定槽12围绕轴承座14的第一端形成,从而连接构件30被装配在固定槽12中。进一步地,固定突起16围绕轴承座14的第二端突出地形成,从而轴承20被设置在连接构件30与固定突起16之间。因此,轴承20的轴向的位置被固定。
详细地,轴承20由装配在等速万向节10上的内圈22、装配在轮毂壳体40的内周表面上的外圈24和容纳在内圈22与外圈24之间的滚珠26构成,从而内圈22被设置在连接构件30与固定突起16之间并且可以在等速万向节10的轴向上位置被固定。
除内圈22、外圈24和滚珠26之外,轴承20可以进一步包括在内圈22与外圈24之间传递扭矩的保持架28。内圈22被设置在连接构件30与固定突起16之间并且在等速万向节10的轴向上位置被固定,从而根据等速万向节10的旋转的动力可以通过轴承20被平稳地传递到轮毂壳体40。
作为轴承20的一部分的外圈24可以被装配在轮毂壳体40,或者外圈24可以与轮毂壳体40一体地形成,从而可以简化结构。
另一方面,如图2所示,螺纹可以围绕轮毂壳体40的内部的内周表面形成并且与轮毂壳体40的螺纹对应的螺纹可以被形成在轮毂盖50的外周表面上。
直的紧固槽52可以形成在轮毂盖50的侧面上。
由于螺纹形成在轮毂壳体40的内部的内周表面上并且螺纹形成在轮毂盖50的外周表面上,因此轮毂盖50可以在轮毂壳体40的内部被螺纹紧固或分离。当轮毂盖50被螺纹紧固到轮毂壳体40时,通过螺纹紧固特性保证强力的联接性能和密封性能。
由于紧固槽52被形成在轮毂盖50的侧面上,因此能够通过将诸如扁平头螺丝刀的工具插入到紧固槽52中来转动轮毂盖50。因此,轮毂盖50可以联接到轮毂壳体40或与轮毂壳体40分离。紧固槽52可以以能够与工具紧固的各种形状来形成。
当本发明的车轮驱动装置的部件损坏或需要被更换时,能够通过将轮毂盖50与轮毂壳体40分离来打开轮毂壳体40的内部,然后通过将工具插入到打开的内部中将连接构件与等速万向节10分离。
进一步地,连接构件30被装配在等速万向节10的第一端上并且位于轴承20的端部,从而连接构件30被暴露。因此,能够通过强制地打开暴露的连接构件30来分离连接构件30并且将等速万向节10与轮毂壳体40彼此分离。
根据具有上述结构的用于车辆的车轮驱动装置,由于轮毂壳体的内部可以被打开和关闭,因此作为车轮驱动装置的内部部件的等速万向节10在必要时可以被分离。由于等速万向节10可以以该方式被更换和修理,因此能够持续维护。
尽管上面结合附图中示出的具体实施例提供了本发明,但对本领域技术人员显而易见的是,在不脱离权利要求中所述的本发明的范围的情况下,可以以各种方式改变和修改本发明。
