Description

一种车轮 技术领域:
本发明涉及一种车轮;特别是涉及一种车轮的紧固连接组件。
背景技术
物体间的螺纹副机械静联接出现一些关键部位连接的螺栓断裂、螺纹连接的失效引起的安全问题和安全事故,经常碰到,是全球面临的通病,也是本领域的技术人员不断研究改进急待解决还没有解决的问题。小螺栓、大事故,经常因螺栓断裂发生重大事故,如汽车的发动机的连杆螺栓断裂造成捣缸事故;2009年4月18日发生的哈尔滨塔吊螺栓断裂造成的1死4伤的事故;据台湾媒体报道的核二厂一号机反应炉检出7支锚定螺栓断裂、毁损可能引起核安全的事故;2012年6月29日16时45分发生的、5号座舱支撑系统的中导柱螺栓发生疲劳断裂、造成深圳东部华侨城“太空迷航”娱乐项目发生6人死亡、10人受伤的重大安全事故;作为高端车辆的代表厂家,因无法解决螺丝断裂的技术问题,导致宝马发动机因螺丝断裂瞬间失去动力熄火事件导致召回23万辆车(宝马(中国)汽车贸易有限公司、华晨宝马汽车有限公司决定自2014年6月18日起,召回23万辆车),制造厂家受到巨大经济损失和商誉损失,更严重的是会造成车主的生命财产安全。虽然在很多情况下,特别是在振动状态下,经常需要对已经锁紧的紧固连接件定期检修加固,防止螺纹副反转松动甚至是松脱带来的安全事故,但全世界每年因为螺纹连接失效导致的一系列安全事故非常多,例子不胜枚举。
车轮在车辆行驶过程中,连接车轮轮毂、轮辐、制动片的紧固连接组件受力大,而且处于不断震动的环境中,并经常受到冲击;采用不止转的紧固件连接车轮的轮毂、轮辐、制动片等,车轮的紧固连接组件的螺纹副容易螺纹连接失效,特别是反转松脱,需要经常检测,对大货车,更容易造成螺纹副连接松动。车轮的螺纹副连接失效,严重可导致安全事故。
螺纹连接的可靠性是靠螺纹副的摩擦产生自锁以及螺纹副的接触面间的摩擦来保证。一般来说,连接螺纹具有一定的自锁性,在静载荷条件下并不会自动松脱。但是,由于连接的工作条件不可避免地会存在冲击、振动、变载荷作用。在这些工况条件下,螺纹副之间的摩擦力会出现瞬时消失或减小;同时在高温或温度变化比较大的场合,材料会发生蠕变和应力松弛,也会使摩擦力减小。在多次作用下,就会造成螺纹连接的逐渐松脱。
螺纹连接的失效,主要原因是由于预紧力减少导致螺纹松脱,因此螺纹连接防松的本质,就是防止螺纹副的反转(也就是内螺纹孔与外螺纹部之间的反转),如螺栓与螺母间的反转。
现有的机械机械防松方法主要包括利用开口销、止动垫片及串钢丝绳等机械防松方法。现在飞机上很多还采用串联钢丝绳的防松方法。
为了防止螺纹连接松脱,人们一直在不懈努力。
专利号为US1755807、申请日为1929年4月6日、公开日为1930年4月22日的美国专利中,公开了一种防松的螺杆螺母结构,包括螺杆、锁紧螺母、止转套。锁紧螺母内设有螺纹通孔和与其连通的内齿轮形的止转孔,止转孔的最小孔径大于螺纹通孔的孔径。止转套设有止转通孔,止转套外周为外齿轮形,止转通孔孔壁上设有止转条,在螺杆上设有与止转条配合的止转槽。止转套的外齿轮形外周与锁紧螺母止转孔内齿轮型孔壁配合约束锁紧螺母相对止转套旋转,止转套的止转套插入螺杆的止转槽约束螺杆相对止转套旋转,因此螺杆与锁紧螺母不可转动地安装在一起。该专利中,由于止转套完全容置在锁紧螺母的止转孔中,止转套很难从锁紧螺母的止转孔中取出;而且在螺杆、螺母的使用过程中,由于止转套、螺杆和螺母生锈、灰尘进入止转套与螺杆和螺母间、止转套与螺杆和螺母的相互渗透等会造成止转套与螺杆螺母间产生很大的咬合力,从而造成止转套无法从螺杆与螺母间取出。如果止转套很难或无法从螺杆与螺母间取出,就很难或无法将螺母和螺杆分离,因而却失去了使用螺纹副连接就是为了能够很方便地将螺杆和螺母分离的最基本用途,因而这种螺杆和螺母结构是没有多大的使用价值。
专利号为ZL201510198765.5、申请公布号为CN 104819197A、申请日为2015年4月24日、公布日为2015年8月6日的发明专利中,一种防松动螺母连接结构,包括连接件及穿过连接件的螺杆,螺杆上旋合螺母将连接件紧固,螺母外侧套接一防松套圈,防松套圈与连接 件间设有防旋转结构,防旋转结构包括连接件上对应螺母设置的沉槽,螺母旋合后底部设于沉槽内,防松套圈外圈设有卡头,沉槽内侧壁设有供卡头卡入的卡槽;防松套圈高度小于沉槽的高度,防松套圈与螺母和沉槽之间为过盈配合。该发明的防松动螺母连接结构,由于增加了一个防松套圈,且防松套圈与连接件间设有防旋转结构,防松套圈内圈为与螺母配合的正六边形结构,防松套圈内圈与螺母间不能相对旋转,同时防旋转结构防止防松套圈与连接件相对旋转,因而可以防止螺母紧固后松动。这种防松动螺母连接结构,虽然实现了防止螺母的松动,但一方面由于防松套圈高度小于沉槽的高度、防松套圈与螺母和沉槽之间为过盈配合,在拆卸防松动螺母连接结构时,防松防松套圈是无法从沉槽内取出,无法取出防松防松套圈,就无法将螺母和螺杆分离,因而却失去了使用螺纹副连接就是为了能够很方便地将螺杆和螺母分离的最基本用途,,因而这种结构是没有任何意义的;另一方面,沉槽内侧壁设有供卡头卡入的卡槽,这种卡槽结构无法机械加工出来,如果不是事先与被连接件一起成型,则需要用电火花等工艺才能加工出来,因而使用成本特别高;还有,如果不对螺杆止转,螺杆相对锁紧螺母还是会转动,只对螺母止转也是没有任何现实意义。上述种种原因,会使本领域的技术人员认为该发明的技术方案无任何使用价值,大大阻碍了本领域的技术人员改进该专利的技术方案的积极性。
专利号为ZL97112246.6、公开日为97112246.6的发明专利中,公开了一种防松螺母,包括工具安装部及与其同轴向上突出设置的环形突出部,它们中间有贯通的螺纹孔。这种防松螺母,就是HardLock螺母,号称世界上唯一的绝不松动的螺母,是哈德洛克工业株式会社的社长若林克彦用了近20年的时间,通过不断技术改进而研究出来的技术成果,现在高铁上应用比较多。高铁运营时,高速行驶的列车和铁轨不断接触,形成的震动非常大,一般的螺丝在这种震动中会被震松震飞。不想被震飞,那么就需要螺丝和螺母丝丝入扣,永不松动才行。这个要求看起来很简单,但是要满足它并不容易。高铁代表中国创造,却用日本螺母,因而有媒体发出类似从一颗螺母看出中国制造和日本制造的差距的感叹。但这种螺母制造工艺非常复杂,制造精度要求特别高,现在的情况是,有产品图、有产品,没有哈德洛克公司的独特的技术和诀窍,却无法制造出来,因而价格昂贵,一个至少几十元钱;这种螺母也无法做到完全不松,只是在现有的防松螺母中防松效果算很好的;这种螺母,重复使用几十次后就不能再用。
专利号为ZL201520399393.8的实用新型专利中,公开了一种自紧螺母、螺栓紧固件,紧固件包括自紧螺母本体、自紧垫圈和普通螺栓;自紧螺母本体与自紧垫圈接触面为平滑过渡的螺旋面;自紧螺母本体与普通螺栓螺纹连接;螺栓紧固件包括自紧螺栓、自紧垫圈和普通螺母;普通螺母与自紧螺栓螺纹连接。该自紧螺母、螺栓紧固件,采用自紧原理,在螺母或螺栓上设置一自紧结构,使其锁紧后达到自紧的效果,让螺母不再出现移位或者松动。这种自己螺母,又称自紧王螺母和永不松动的螺母,并宣称其防松能力超过hardlock螺母,在央视中有报道。这种螺母由于没有广泛使用,其防松效果如何,无法判断。
从专利号为US1755807、申请日为1929年4月6日的美国专利中,发明了用止转套来限制螺栓相对螺母转动的防松技术,到专利号为ZL201510198765.5、申请日为2015年4月24日的中国发明专利中,再次提出止转套来限制螺母转动的技术方案,历时八十六年,都没有解决既能用止转套对螺栓和螺母防松或用止转套对螺栓和螺母防松、又能方便快速可靠的将止转套从止转孔中取出从而使螺栓和螺母拆离的技术问题。现有的认为防松效果好的hardlock螺母、自紧王螺母,都不是通过采用止转套阻止螺母转动来实现螺栓螺母防松;快一个世纪过去了,还没有通过采用止转套阻止螺母转动来实现螺栓螺母防松的技术应用;可见,人们陷入了虽然采用止转套能阻止螺母转动来实现螺栓螺母防松、但螺栓螺母却很难或无法拆卸的技术误区,形成了采用止转套阻止螺母转动来实现螺栓螺母防松的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套阻止螺母转动来实现螺栓螺母防松的技术方案的积极性
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限制螺母相对螺杆转动、来实现螺栓螺母反转松脱的防松技术方案、因止转套很难或无法从第一止转孔中取出、导致无使用价值的惯性思维,本发明提供了一种车轮,采用止转套限制螺纹副无法相对转动、使螺纹副不会因为反转而松脱且止转套从第一止转孔中取出快速、方便、可靠,从而使螺杆、螺母等的拆离快速、方便、可靠的紧固连接组件来 连接车轮的各个构件。
一种车轮,包括轮辐,在轮辐上还设有三个以上以轮辐轴心为中心周向分布的第一通孔;还包括止转套;在轮辐外侧设有通过与之配合的止转套来约束螺杆或螺母转动、与第一通孔连通并同轴的第一止转孔;
第一止转孔的最小孔径大于第一通孔的孔径;在第一止转孔的孔壁上设有轴向的第一止转部;止转套的外周与第一止转孔的孔壁配合;在止转套的外周设有与第一止转部配合、轴向的第二止转部;在止转套上设有轴向的第一止转通孔,第一止转通孔的孔壁上设有轴向的第三止转部。
在第一止转孔的孔壁和/或止转套上、设有将安装在锁紧螺母外和第一止转孔内的止转套取出的取出结构。第一止转孔和止转套外周的第三止转部为六个以上且周向均匀排列,或止转通孔孔壁上的第二止转部为六个以上且周向均匀排列。
作为改进,止转套安装在第一止转孔内;在第一止转孔的孔壁和/或止转套上、设有将安装在锁紧螺母外或螺杆的止转抵挡部外、第一止转孔内的止转套取出的取出结构。
作为改进,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。
作为改进,取出结构还包括在止转套朝向第一止转孔的底面的一侧与第一止转孔底部形成与夹持孔或夹持凹陷部连通、供拆卸工具的夹持钩穿过夹持孔或夹持凹陷部进入的取出空间。
作为改进,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两个取出槽。
作为改进,取出结构还包括在止转套朝向第一止转孔的底面的一侧与第一止转孔间设有与取出槽连通的取出空间。
在第一止转孔的孔壁上设有两个取出槽,便于拆卸工具如夹钳从取出槽和取出空间夹持取出止转套,在拆卸紧固连接组件时,用拆卸工具夹持取出止转套,能非常省力、快速、快速、可靠地将止转套从第一止转孔中取出来。
在止转套与第一止转孔间设有取出空间,在夹持取出止转套时,拆卸工具伸入取出空间内,这样不仅依靠夹持工具与止转套的夹紧摩擦力来夹持取出止转套,而且增加了拆卸工具对止转套在背离取出方向的抵挡力,因而可以非常可靠地取出止转套。在止转套和第一止转孔间增加取出槽和取出空间,特别适用于止转套壁厚薄和需较大的夹持力才能将止转套从止转孔中取出的情况;这种结构的紧固连接组件,若不在止转套和第一止转孔间增加取出结构,很难甚至无法将止转套从第一止转孔中取出;对因在使用过程中,止转套与第一止转孔间因生锈、灰尘等进入、长期使用产生止转套与第一止转孔咬合等导致止转套完全卡死在第一止转孔内的情况,借助拆卸工具,这种结构的紧固连接组件的止转套也能很可靠地从第一止转孔中取出。
作为改进,在轮辐的外侧面上对应每个第一止转孔均设有与第一止转部对应、过第一止转孔的轴线的径向的第一刻度线,第一刻度线分布在第一止转孔的外周。
通过套筒扳手正向或反向旋转微调锁紧螺母角度,因第一刻度线径向凸出第一止转孔、第一刻度线径向凸出套筒的外周,通过目测使第二刻度线与第一刻度线共面,从而是锁紧螺母的第一止转部与第一止转孔的第四止转部位置关系对应。

本发明的有益效果是:
既要阻止螺纹副反转防松,又要保持机械螺纹连接的方便、快速、可靠地可拆卸性,是人们一直长期以来致力解决却没有彻底解决的技术难题。
本发明通过止转套限制螺纹副相对反转,从而使螺杆、螺母等不可转动地安装在轮辐、制动件、轮毂等上,防止紧固连接组件在使用过程中螺纹副反转松脱。止转套与第一止转孔和锁紧螺母或螺杆之间一般为间隙配合,便于止转套的安装和取出。
为了锁紧螺母安装在第一止转孔后,锁紧螺母的第一止转部和第一止转孔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。
在第一止转孔的孔壁上和/或止转套上、设有将安装在锁紧螺母或螺杆外、和第一止转件的第一止转孔内的止转套取出的取出结构,使止转套能方便、快速、可靠地从第一止转孔中取出,即使是止转套完全容置在第一止转孔中。止转套从第一止转孔中取出后,螺杆和螺母的拆卸、或螺杆的拆卸与传统的螺杆和螺母拆卸、或螺杆的拆卸等完全是一样的,因而螺杆、螺母等的拆卸方便、快速、可靠。
螺纹副不会因为相对转动反转而松脱,使螺纹副的螺纹连接保持在最初需要的锁紧位置,螺纹副的螺纹连接的夹紧力在使用过程中基本无变化;即使采用普通的螺纹副的螺纹连接,在剧烈震动、高温等恶劣环境下,螺纹副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,能有效避免螺纹副的螺纹连接因相对反转松脱失效。
在止转套上仅设有一个止转通孔,紧固连接组件的适用范围广,不受轮辐上用来安装螺杆的孔的孔距限制,但需在轮辐上设计对止转套止转的第一止转孔,或用相对轮辐无转动地第一止转件来约束止转套旋转;这种紧固连接结构,结构更紧凑,更符合通用的标准件紧固件的安装和使用习惯,可以设计成标准件。
