Description

自行车无极变速器 技术领域
本实用新型涉及变速器，具体涉及一种自行车无极变速器。
 背景技术
目前，普通自行车是用脚踏花盘，通过链条传动给飞轮，属轮轴杠杆运动，但由于轮与轴半径比值较小，省力效果仍不够理想；加之花盘直径较大，飞轮直径较小，传动链条与水平线夹角较大，分解了传动的力，骑行时还是会感到费力。
 技术问题
本实用新型的目的是：设计一种自行车无极变速器，结构简单，成本低廉，杠杆原理，骑车省力，适合爬坡。
技术解决方案
本实用新型的技术解决方案是：该自行车包括车架、脚踏杆和脚踏，一对脚踏杆通过转轴安装在车架上，脚踏安装在脚踏杆上，其特征是：在自行车上安装无极变速器，所述的无极变速器包括长轴、连杆轴、手把转轮、锁止块、钢丝绳、转轮、滑块、齿条杆、单向顺时针齿轮、单向逆时针齿轮、一号大齿轮、二号大齿轮和中心轴，长轴安装在车架上，长轴的两端分别通过连杆轴连接脚踏杆，带锁止块的手把转轮安装在手把上，脚踏杆内安装转轮，钢丝绳缠绕在手把转轮和转轮上，钢丝绳上固定滑块，车架上通过中心轴安装单向顺时针齿轮和二号大齿轮，单向逆时针齿轮和一号大齿轮通过轴安装在车架上，一号大齿轮啮合二号大齿轮，齿条杆的一端活动连接滑块，齿条杆的另一端通过两个转轮和连接块安装在车架上并使齿条杆的齿条啮合单向顺时针齿轮和单向逆时针齿轮。
其中，钢丝绳上套装防护管，防护管的一端连接手把转轮，防护管的另一端连接脚踏杆。
本实用新型的原理是：单向齿轮只是向一个方向转动，自身转动时不会带动下面的大齿轮转动，反方向是被锁死的，自身转动不了；当反方向转动被锁死时，则会带动下面的大齿轮一起转动；齿条杆直接作用于单向齿轮，而下面的大齿轮是由单向齿轮带动。
有益效果
本实用新型的优点是：结构简单，成本低廉，操作方便，没有档位，不会打滑，运行稳定。
