一种可进行微调夹紧力的自行车花鼓
:本技术涉及一种可进行微调夹紧力的自行车花鼓。
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之间,利用锁紧螺钉旋进主轴两端螺孔内,锁紧螺钉的锁紧力经叉杆后传递给端盖,端盖压住轴承,从而实现花鼓的安装,这种安装结构因端盖与轴承之间光滑的轴与轴孔配合,夹紧力直接经锁紧螺钉—叉杆—端盖后传递给轴承,一旦安装完成后,夹紧力是没办法调整的,有时因夹紧力过大会导致轴承转动阻力变大,增加了骑乘的体力消耗,或者有时会出现夹紧过松,导致轴承受力不均匀,增加轴承磨损的不均匀度。
技术实现思路
:本技术的目的是为了克服上述现有技术的缺点,提供一种可进行微调夹紧力的自行车花鼓。本技术的专利技术目的可以通过以下的技术方案来实现:一种可进行微调夹紧力的自行车花鼓,包括有主轴和外壳,主轴两端面成型有螺孔,在外壳内设置有左轴承和右轴承,主轴穿过左轴承和右轴承,在主轴的两端设置有端盖,右端盖的内侧压住右轴承,在主轴上位于左端盖的一侧套装有调整盖,调整盖的内侧压住左轴承,调整盖与主轴成螺纹连接,在非螺纹连接段调整盖与主轴之间设置有阻尼圈。采用本技术方案后,与现有技术相比,本技术方案具有以下优点:利用调整盖的旋转,实现对左轴承的压紧调整,从而调节两叉杆对花鼓的夹紧力,使夹紧力 ...
