背景技术
现有技术中的轮毂单元结构相对复杂，而且装配精度较低，同时使用效果不出色。
中国专利200420119173.7  ，公开一种带轴承的轮毂单元，包括法兰盘，其特征是所述的法兰盘外设有轴承座，法兰盘与轴承座之间设有两个单列的圆锥轴承；法兰盘靠近小端面的轴颈外径处设有挡圈，挡圈端面压紧轴承一内圈的大端面；轴承座内径两侧设有密封圈，其外侧内径与法兰盘密封台阶接触，内侧内径与挡圈的外径接触。此结构相对复杂，而且使用效果较差，同时使用寿命较短。
发明内容
   本实用新型主要是解决现有技术中存在的不足，结构紧凑，同时安装精度高，延长使用寿命的对称式轮毂单元。
本实用新型的上述技术问题主要是通过下述技术方案得以解决的： 
一种对称式轮毂单元，包括带有装配腔的法兰盘，所述的法兰盘外分别套有窄内圈和宽内圈，所述的窄内圈和宽内圈呈阶梯分布，所述的窄内圈和宽内圈外套有外圈，所述的窄内圈与外圈间、宽内圈与外圈间分别设有滚子，所述的滚子通过保持架相定位，所述的宽内圈上套有齿圈，所述的外圈插接有与之相垂直分布的传感器，所述的传感器的底部延伸出外圈。
此结构适配性强，同时装配精度高。
作为优选，所述的窄内圈与外圈间通过前密封圈相密封，所述的宽内圈与外圈间通过后密封圈相密封，所述的后密封圈包覆住外圈的尾部，所述的传感器与外圈通过O型圈相密封。
作为优选，所述的传感器的头部端面与齿圈的外壁端面呈直线状分布。
作为优选，所述的法兰盘上设有均匀分布的紧固螺栓，所述的外圈上设有三个装配折角，所述的装配折角中设有装配螺栓。
    因此，本实用新型提供的一种对称式轮毂单元，结构紧凑，提高装配精度，提升使用寿命。
附图说明
图1是本实用新型的剖视结构示意图；
图2是本实用新型的侧视结构示意图。
具体实施方式
