Description

一种连接轴装置及自行车 技术领域:
本发明涉及一种将各个零部件安装在连接轴上的连接轴装置及具有这种连接轴装置的自行车,特别是涉及一种自行车的前轮组件、后轮组件、车头杆组件、车座组件、踏板组件等。
专利号为ZL03154643.X、公开日为2004年3月31日的发明专利中,公开了一种容易进行滚珠接触状态的调整作业和滚珠推压件的止转作业的自行车用轮毂。自行车用轮毂为将车轮相对自行车的车架可自由回转地安装用的轮毂,具有轮毂轴,轮毂体,一对轴承和止转部件。轮毂轴不能回转地安装在车架上并且一端侧具有外螺纹部和与外螺纹部的轴方向外方邻接而成的第1连接固定部。轮毂体具有左右一对第1和第2轮毂凸缘,并且位于轮毂轴的外周侧。一对轴承位于轮毂体与轮毂轴之间,具有设置在轮毂体上的左右一对第1和第2滚珠座,带有与轮毂轴的外螺纹部螺纹配合的内螺纹部以及止转用的第2连接固定部的第1滚珠推压件,在轮毂轴的另一端侧设置成相对轮毂轴不能回转的第2滚珠推压件,以及在两个滚珠推压件和两个滚珠座之间分别与两者以接触方式滚动的滚珠。
止转部件为具有第1内周面和直径小于第1内周面的第2内周面的筒状部件,在第2内周面上形成1第接合部,在第1内周面上形成第2接合部。第1接合部与轮毂轴的第1轴部的第1连接固定部不能回转地连接固定,由在第2内周面上相互平行而成的长圆形的缝隙构成。第2接合部由在第1内周面上具有在周向并排的多个凹凸而成的锯齿形部构成,以与第2连接固定部的锯齿形部接合。该止转部件由于与轮毂轴和第1滚珠推压件不能回转地连接固定,第1滚珠推压件可相对轮毂轴止转。
第1滚珠推压件可相对轮毂轴止转,虽然通过止转部件约束了第1滚珠推压件可相对轮毂轴止转,但要将由在止转部件的第1内周面上、具有在周向并排的、多个凹凸而成的、锯齿形部构成的第2接合部与第1滚珠推压件的第2连接固定部的锯齿形部接合是非常困难的,甚至是无法结合的,理由如下:
在装配时,先将第1滚珠推压件螺纹连接在轮毂轴上;再将止转部件第一内周面安装在第一滚珠推压件外,最后将第二内周面安装在轮毂轴的第1轴部的第1连接固定部外。安装时,止转部件第一内周面与第一滚珠推压件先接触,因而需将止转部件的第2结合部与第一滚珠推压件的第2连接固定部正对后才能凹凸配合安装在一起。因止转部件为具有第1内周面和直径小于第1内周面的第2内周面的筒状部件,这样在安装时,止转部件的第二内周面朝向轮毂轴的外侧端,第一内周面朝向轮毂轴的中心,导致安装时在端面方向无法目测止转部件的第2结合部与第一滚珠推压件的第2连接固定部是否正对。又由于在第2内周面上形成1第接合部,在周向方向也无法目测止转部件的第2结合部与第一滚珠推压件的第2连接固定部是否正对。这样即使在安装第一滚珠推压件时,第一滚珠推压件的第2连接固定部与轮毂轴的第1轴部的第1连接固定部位置关系对应,如果在安装时,无法目测将止转部件的第2结合部与第一滚珠推压件的第2连接固定部正对,止转部件的第2结合部很难或无法与第一滚珠推压件的第2连接固定部接合。由于止转部件的第2结合部很难或无法与第一滚珠推压件的第2连接固定部接合,因而这种技术方案是无多大使用价值的。
还有,由于第2连接固定部设置在第一滚珠推压件外,对于锯齿形部的第2连接固定部,夹持第2连接固定部将第一滚珠推压件螺纹连接在轮毂轴上时,一方面会影响夹持力,另一方面会使锯齿变形,使止转部件的第2结合部与第一滚珠推压件的第2连接固定部的结合更加困难,如果锯齿太小太尖,变形大的情况。下,还会导致止转部件的第2结合部与第一滚珠推压件的第2连接固定部无法结合。
还有,由于止转部件安装在第一滚珠推压件外,不适合第一滚珠推压件外周不够空间或第一滚珠推压件外周形状不能改变等情况。
专利号为ZL03154643.X的中国发明专利中,虽然发明了用止转部件来限制第一滚珠推压件相对轮毂轴转动的防松技术,但因止转部件的第2结合部很难或无法与第一滚珠推压件的 第2连接固定部接合,因而这种技术方案无多大使用价值,使人们陷入了虽然采用止转部件能约束第一滚珠推压件相对轮毂轴转动来实现第一滚珠推压件防松、但止转部件的第2结合部很难或无法安装在第一滚珠推压件的第2连接固定部外的技术误区,形成了采用止转部件来限制第一滚珠推压件相对轮毂轴转动的防松技术无使用价值的惯性思维,从而阻止了本领域的技术人员改进采用止转部件来限制第一滚珠推压件相对轮毂轴转动的防松技术方案的积极性。
发明内容
针对现有技术中存在的问题,本发明要解决的技术问题是,克服现有的本领域的技术人员认采用止转套来限制锁紧件相对连接轴转动的防松技术、因止转套与锁紧件相互止转的止转结构安装困难或无法安装导致无使用价值的惯性思维,提供一种采用止转套限制锁紧件相对连接轴转动来实现连接轴锁紧件无法相对转动、使连接轴锁紧件不会因为反转而松脱且止转套取出快速、方便、可靠、从而使连接轴和锁紧件的拆离快速、方便、可靠的连接轴装置及自行车。
一种连接轴装置,包括连接轴、锁紧件;在锁紧件上设有螺纹通孔,在连接轴上设有与锁紧件配合的外螺纹部,还包括止转套;锁紧件内设有与螺纹通孔连通的止转孔,止转孔的最小孔径大于螺纹通孔的孔径,止转孔的孔壁上设有周向排列的第一止转部;止转套上设有轴向的止转通孔,止转套的外周设有与第一止转部配合、周向排列的第二止转部,止转通孔的孔壁上设有第三止转部;在连接轴上对应外螺纹部设有与第三止转部配合的第四止转部;在锁紧件和/或止转套上、设有将安装在连接轴外和锁紧件的止转孔内的止转套取出的取出结构;外螺纹部与锁紧件螺纹连接,锁紧件的第一止转部与连接轴的第四止转部位置关系对应;止转套安装在设有第四止转部的连接轴外并置于止转孔内,止转套轴向限位在止转孔内;第三止转部与第四止转部配合约束止转套相对连接轴旋转,第一止转部与第二止转部配合约束锁紧件相对止转套旋转,连接轴和锁紧件不可转动地安装在一起。
锁紧件可为机械零件。连接轴和锁紧件不可转动地安装在一起;一方面锁紧件不会因为反转松脱而导致锁紧件与连接轴的外螺纹部螺纹连接的失效,确保锁紧件与连接轴的连接可靠;另一方面由于锁紧件无法反转,锁紧件始终保持在与连接轴的最初安装位置,确保被连接件能精确的安装在连接轴设定的位置上,大大提高设备的精度。
在连接轴的轴向方向不同位置设有与相应的锁紧件配合的外螺纹部,通过安装在连接轴上的两个锁紧件对被连接件轴向限位,这种结构的连接轴装置,特别适用于用在自行车的车轮上。
作为方案一的改进,取出结构包括设置在止转套上两个轴向的夹持孔或设置在止转套的外周上、与止转套外周连通的两个轴向的夹持凹陷部。
在止转套上设有两个以上用来将止转套从第一止转孔中夹持取出的夹持孔或夹持凹陷部,取出止转套时,只需伸入两个夹持孔或夹持凹陷部内夹持住止转套从而将止转套从第一止转孔中取出,使止转套从第一止转孔中取出快速、方便、可靠。一般情况下可借助夹持工具夹持止转套将止转套从第一止转孔中取出,从而使止转套从第一止转孔中取出更加快速、方便且可确保止转套从第一止转孔中取出。
在止转套上设有两个以上用来将止转套从第一止转孔中夹持取出的夹持孔,不需在第一止转孔的孔壁上再设计取出止转套的结构,在成型止转套时成型夹持孔,几乎不增加成本,且止转套一般设计成标准件,因此可大大降低成本。
在止转套壁厚较薄、没有足够的空间设置夹持孔的情况下,在止转套外周设有夹持凹陷部结构,还可在第一止转孔的孔壁上设计与夹持凹陷部配合的结构形成一个夹持孔,在保证止转套刚性和强度的情况下,还能使夹持凹陷部的孔径满足夹持需要。
作为方案一的改进,取出结构包括设置在第一止转孔的孔壁上、与第一止转孔的孔壁及第一止转孔的顶面连通的一个以上的取出槽。
在第一止转孔的孔壁上设有两个取出槽,便于从取出槽位置夹持取出止转套。设有一个以上的取出槽,可用一薄片工具从取出槽位置稍微撬一下止转套就可取出止转套,止转套的取出特别方便。

作为方案七的改进,连接轴装置还包括止转套限位件;锁紧件为锁紧螺母,连接轴为转向节;转向节包括转向节轴和转向节臂;锁紧件外螺纹部设置在转向节轴远离转向节臂的一端;止转套限位件安装在转向节轴远离转向节臂的一端或锁紧螺母上对止转套背离转向节臂的一侧轴向限位。
作为方案八的改进,第三止转部周向排列在止转通孔的孔壁上;在锁紧件外螺纹部上设有与止转套的止转通孔配合的止转轴,第四止转部设置在止转轴的外周;第四止转部的最大外径小于或等于锁紧件外螺纹部的螺纹底径;止转轴置于第一止转孔内,止转套安装在止转轴外并置于第一止转孔内。
第三止转部周向排列在止转套的止转通孔的孔壁上,第四止转部设置在止转轴的外周,在满足加工和受力的情况下,第三止转部和第四止转部尽可能多等分,这样在保证转向节与第二锁紧螺母的锁紧力的情况下,微调转向节,更易使转向节上的第一止转部与第四止转部位置关系对应,满足止转套安装需要。
止转轴的外周为外齿轮形结构、或花键形结构、或正正多边形孔;止转套的止转通孔的孔壁为与外齿轮形结构的止转轴的外周配合的内齿轮形孔、或为与花键形结构的止转轴的外周配合的花键形孔、或为与正正多边形结构的止转轴的外周配合的正正多边形孔、或为与正正多边形结构的止转轴的外周配合的两个以上结构相同的正多边形孔的相交结构。

本发明的有益效果是:
本发明通过止转套限制锁紧螺母或锁紧件或珠堵等或锁紧件或珠堵等相对连接轴旋转,从而使连接轴与锁紧螺母或锁紧件或珠堵等不可转动地安装在一起,防止锁紧螺母或锁紧件或珠堵等或锁紧件或珠堵等在使用过程中相对连接轴反转而发生位移或松脱。止转套与锁紧螺母或锁紧件或珠堵等的第一止转孔之间一般为间隙配合,便于止转套的安装和取出。
为了锁紧螺母或锁紧件或珠堵等与连接轴螺纹连接后,第一止转孔上的第一止转部和连接轴的第四止转部位置关系能对应,在设计止转套时注意止转套的第二止转部与第三止转部的位置对应关系,也就是第二止转部与第三止转部要有对应的规律。
在止转套上设有将止转套从第一止转孔中夹持取出的取出结构,使止转套从第一止转孔中取出快速、方便、可靠。止转套从第一止转孔中取出后,连接轴与锁紧螺母或锁紧件或珠堵等的拆卸与传统的连接轴与锁紧螺母或锁紧件或珠堵等拆卸完全是一样的,因而连接轴与锁紧螺母或锁紧件或珠堵等的拆卸方便、快速、可靠。
止转套安装在止转孔内,安装时可以非常方便的目测止转套外止转部与止转孔的止转部对应关系,因而能非常容易的将止转套外止转部与止转孔的止转部正对,使止转套安装在连接轴外和止转孔内非常方便。
连接轴与锁紧螺母或锁紧件或珠堵等螺纹连接后,止转套约束连接轴与锁紧螺母或锁紧件或珠堵等都无法转动,连接轴与锁紧螺母或锁紧件或珠堵等间就不会因为反转而松脱,使连接轴与锁紧螺母或锁紧件或珠堵等间保持在最初需要的锁紧位置,连接轴与锁紧螺母或锁紧件或珠堵等的螺纹连接的夹紧力在使用过程中基本无变化;即使采用普通的连接轴锁紧螺母或锁紧件或珠堵等连接,在剧烈震动、高温等恶劣环境下,连接轴与锁紧螺母或锁紧件或珠堵等的螺纹连接的夹紧力在使用过程中基本无变化;因此达到最好的锁紧效果,能有效避免连接轴与锁紧螺母或锁紧件或珠堵等螺纹连接失效。
止转套的外周可为花键形或正多边形或外齿轮形;第一止转孔的孔壁为与外齿轮形结构的止转套外周配合的内齿轮形孔、或为与花键形结构的止转套外周配合的花键形孔、或为与正多边形结构止转套配合的正多边形孔、或为与正多边形结构止转套配合的两个以上结构相同的正多边形孔的相交结构且每相邻的两正多边形孔旋转的度数为360°/正多边形孔边数/正多边形孔个数。在满足加工和使用的前提下,成型越多个相互配合第一止转部和第二止转部,这样在连接轴与锁紧螺母或锁紧件或珠堵等的螺纹连接处于最佳锁紧的状态下,为了安装止转套,微调锁紧螺母或锁紧件或珠堵等时的角度越小,就能使锁紧螺母或锁紧件或珠堵等的第一止转部与连接轴的第四止转部位置关系对应,满足止转套安装需要。微调锁紧螺母或锁紧件或珠堵等的角度越小,连接轴与锁紧螺母或锁紧件或珠堵等间的锁紧效果越好,避免连接轴与锁紧螺母或锁紧件或珠堵等间的锁紧力过大或过小。
本发明通过止转套限制锁紧螺母或锁紧件或珠堵等或锁紧件或珠堵等相对连接轴旋转,从而使连接轴与锁紧螺母或锁紧件或珠堵等不可转动地安装在一起,防止锁紧螺 母或锁紧件或珠堵等或锁紧件或珠堵等在使用过程中相对连接轴反转而发生位移或松脱。止转套与锁紧螺母或锁紧件或珠堵等的第一止转孔之间一般为间隙配合,便于止转套的安装和取出。
为了锁紧螺母或锁紧件或珠堵等与连接轴螺纹连接后,第一止转孔上的第一止转部和连接轴的第四止转部位置关系能对应,在设计止转套时注意止转套的第二止转部与第三止转部的位置对应关系,也就是第二止转部与第三止转部要有对应的规律。
在止转套上设有将止转套从第一止转孔中夹持取出的取出结构,使止转套从第一止转孔中取出快速、方便、可靠。止转套从第一止转孔中取出后,连接轴与锁紧螺母或锁紧件或珠堵等的拆卸与传统的连接轴与锁紧螺母或锁紧件或珠堵等拆卸完全是一样的,因而连接轴与锁紧螺母或锁紧件或珠堵等的拆卸方便、快速、可靠。
连接轴与锁紧螺母或锁紧件或珠堵等螺纹连接后,止转套约束连接轴与锁紧螺母或锁紧件或珠堵等都无法转动,连接轴与锁紧螺母或锁紧件或珠堵等间就不会因为反转而松脱,使连接轴与锁紧螺母或锁紧件或珠堵等间保持在最初需要的锁紧位置,连接轴与锁紧螺母或锁紧件或珠堵等的螺纹连接的夹紧力在使用过程中基本无变化;即使采用普通的连接轴锁紧螺母或锁紧件或珠堵等连接,在剧烈震动、高温等恶劣环境下,连接轴与锁紧螺母或锁紧件或珠堵等的螺纹连接的夹紧力在使用过程中基本无变化;因此达到最好的锁紧效果,能有效避免连接轴与锁紧螺母或锁紧件或珠堵等螺纹连接失效。
止转套的外周可为花键形或正多边形或外齿轮形;第一止转孔的孔壁为与外齿轮形结构的止转套外周配合的内齿轮形孔、或为与花键形结构的止转套外周配合的花键形孔、或为与正多边形结构止转套配合的正多边形孔、或为与正多边形结构止转套配合的两个以上结构相同的正多边形孔的相交结构且每相邻的两正多边形孔旋转的度数为360°/正多边形孔边数/正多边形孔个数。在满足加工和使用的前提下,成型越多个相互配合第一止转部和第二止转部,这样在连接轴与锁紧螺母或锁紧件或珠堵等的螺纹连接处于最佳锁紧的状态下,为了安装止转套,微调锁紧螺母或锁紧件或珠堵等时的角度越小,就能使锁紧螺母或锁紧件或珠堵等的第一止转部与连接轴的第四止转部位置关系对应,满足止转套安装需要。微调锁紧螺母或锁紧件或珠堵等的角度越小,连接轴与锁紧螺母或锁紧件或珠堵等间的锁紧效果越好,避免连接轴与锁紧螺母或锁紧件或珠堵等间的锁紧力过大或过小。
滚珠先通过黄油安装在珠碗的内周。通过珠堵止转套内止转部与止转珠堵部配合约束珠堵止转套相对连接轴旋转,珠堵止转部与珠堵止转套外止转部配合约束珠堵相对珠堵止转套旋转,使两个珠堵与连接轴均不可转动地安装在一起,这样两珠堵就能精确安装在连接轴的设定位置上,从而使珠碗、滚珠和珠堵之间的配合保持最佳松紧度。
通过螺母止转套内止转部与止转螺母部配合约束螺母止转套相对连接轴旋转,螺母止转部与螺母止转套外止转部配合约束锁紧螺母相对相应的螺母止转套旋转,连接轴和两个锁紧螺母均不可转动地安装在一起;一方面锁紧螺母不会因为反转松脱而导致锁紧螺母与连接轴的外螺纹部螺纹连接的失效,确保通过锁紧螺母对连接在轴上的连接件轴向限位可靠;另一方面由于锁紧螺母无法反转,锁紧螺母始终保持在与连接轴的最初安装位置,确保连接件能精确的安装在连接轴设定的位置上。
止转孔止转部与轴止转套外止转部配合约束轴止转套相对轴止转套止转孔旋转,轴止转套内止转部与轴止转部配合约束连接轴相对轴止转套旋转,连接轴和连接件不可转动地安装在一起,确保连接轴无转动地安装在连接件上,且连接件在连接轴上的位置不会因使用二发生变化。
