Technical Problem

[0005]本实用新型的目的是提供一种防滑脱的电动车前叉轮毂安装结构,通过轮毂碟盘、外定位柱、定位螺栓、前叉轮毂体、第一自锁盘、弹簧杆和第二自锁盘实现让该电动车前叉轮毂安装结构具备了防滑脱的能力,这样的设计可避免轮毂在安装过程中因震动或外力导致的偏移,确保轮毂与前叉的精准对接,而且齿止机构,在震动或负载变化时,齿面接触可抵抗滑脱力矩,防止轮毂与前叉的相对转动或位移,显著提升连接可靠性,这样再协同上弹簧杆的缓冲作用,还可维持轮毂与前叉的稳定接触,这样长期使用下电动车前叉轮毂安装结构可有效防止轮毂在高速或重载场景下脱落,降低交通事故风险的效果,以解决现有技术中电动车前叉轮毂安装结构在使用过程中,由于缺少防滑脱的能力,这样会导致轮毂会因安装误差或震动产生轴向或周向位移,而且在急刹车或高速过弯时,轮毂还会因扭矩突变而滑脱,引发失控风险,这样长期使用下缺少防滑脱设计还会导致电动车前叉轮毂安装结构的安全性下降,容易引发交通事故的问题

Benefits of technology

本实用新型设置有轮毂碟盘、外定位柱、定位螺栓、前叉轮毂体、第一自锁盘、弹簧杆和第二自锁盘,当轮毂碟盘与前叉轮毂体安装的时候,通过外定位柱嵌入到前叉轮毂体的凹槽中,然后再通过定位螺栓进行连接,这样加强安装连接的稳定性,接着第一自锁盘与第二自锁盘通过自锁齿与自锁槽的相互配合,形成了齿止机构,这样在前叉轮毂体传递震动力的时候,相互啮合的第一自锁盘与第二自锁盘可以减少滑脱的情况,同时在轮毂碟盘与第一自锁盘之间还配备了多个弹簧杆,弹簧杆两端的端套内部设置有弹子珠,不仅可以减缓传递到轮毂碟盘和第一自锁盘上的震动力,而且还能保持电动车前叉轮毂安装结构的稳定性,这样配合使用下让该电动车前叉轮毂安装结构具备了防滑脱的能力,这样的设计可避免轮毂在安装过程中因震动或外力导致的偏移,确保轮毂与前叉的精准对接,而且齿止机构,在震动或负载变化时,齿面接触可抵抗滑脱力矩,防止轮毂与前叉的相对转动或位移,显著提升连接可靠性,这样再协同上弹簧杆的缓冲作用,还可维持轮毂与前叉的稳定接触,这样长期使用下电动车前叉轮毂安装结构可有效防止轮毂在高速或重载场景下脱落,降低交通事故风险。

Abstract

The utility model relates to the electric motor car front fork wheel hub installation field, concretely relates to an anti -slip electric motor car front fork wheel hub installation structure, including wheel hub dish, the main part for electric motor car front fork wheel hub installation, fixed cavity, fixedly installed in the outside left side of wheel hub dish, for and electric motor car front fork wheel hub cooperation installation. The utility model is provided with wheel hub dish, outer positioning column, positioning bolt, front fork wheel hub body, first self -locking disc, spring rod and second self -locking disc, when wheel hub dish and front fork wheel hub body install, through the recess in the embedding of outer positioning column to front fork wheel hub body, then connect through positioning bolt again, like this strengthen the stability of installation connection, then first self -locking disc and second self -locking disc cooperate through the interlocking tooth and self -locking groove, form the tooth stop mechanism, like this when the transmission vibration power of front fork wheel hub body, the first self -locking disc and second self -locking disc of interlock can reduce the condition of slipping.
