一种自锁式微调夹紧的自行车花鼓
:本专利技术涉及一种自锁式微调夹紧的自行车花鼓.。
技术介绍
:自行车花鼓位于自行车车轮的中心。传统的自行车花鼓包括主轴、外壳、轴承和锁定构件。主轴安装到自行车车架。外壳经由轴承绕主轴被可旋转地支撑。轴承设置在主轴和外壳之间。锁定钩件用于把花鼓锁紧在自行车叉杆上。传统的自行车花鼓的安装是把花鼓夹装在两叉杆01之间,如图1所示,利用锁紧螺钉02旋进主轴两端螺孔内,锁紧螺钉02与端盖03一起锁紧两侧叉杆01,另外锁紧螺钉02的夹紧力通过端盖03传递压住两侧轴承04,从而实现花鼓的安装,但这种锁紧力是不能实现对轴承04微调的,这种装配所需的锁紧力必须要对叉杆01实现可靠的锁紧,骑车过程叉杆01与花鼓之间锁紧不能出现松动,否则会存在危险,但在实际装配中,因叉杆01受工艺因素影响,两侧叉杆01不是理想的对称关系,在旋动锁紧螺钉02的过程中存在左右两端对叉杆01的锁紧力不平行,这又会导致承重的不平行而使两侧轴承04受压不均衡,自行车使用一段时间后两侧轴承04磨损不一致,自行车很快就会出现维修或更换轴承的问题,有时因夹紧力过大会导致轴承04转动阻力变大,增加了骑乘的体力消耗。为此厂家设计了一款对叉杆01可进行微调的花鼓,目的是为了解决自行车完成装配后花鼓内两侧轴承04的受力均匀性,如图1所示。其结构是在花鼓主轴05的其中一侧增加一调节环06,调节环06套装在主轴05上并与主轴05形成螺纹连接,旋动调节环06使其沿主轴05轴向移动,这样就可以实现对轴承04夹紧力的调节,最终使两侧轴承04受力均匀,但这种结构因调节环06没有设计自锁装置,会导 ...
