带传动齿轮的汽车轮毂单元
本技术涉及轮毂单元
,具体涉及一种带传动齿轮的汽车轮毂单元。
技术介绍
汽车后轮轮毂单元作为汽车配件,主要作用是承重和轮毂的转动提供精确的引导,它既承受轴向载荷又承受径向载荷。轮毂单元产品主要配套于汽车中,轮毂单元是在标准角接触球轴承和圆锥滚子轴承的基础上发展起来的,一般应用于轿跑车、轿车及皮卡车。轮毂单元是整车部件中一个很重要的部件,轿车的轮毂轴承过去最多的是成对使用单列圆锥滚子或球轴承。装配时经过调隙,预紧、添脂等诸多工序,搀杂的人为控制因素多,装配难度较大,从而使得装配线长,成本高且可靠性差,难以适应激烈的市场竞争。中国专利CN200620108249.5,公开一种汽车轮毂单元总成,包括芯轴、外圈、内圈、第一滚动体和第二滚动体,芯轴的外侧配有沟道,外圈的内侧配有双列沟道,外圈与内圈之间夹持有第一滚动体,外圈与芯轴之间夹持有第二滚动体,内圈固接于从其内部穿过的芯轴上,内圈的内径与芯轴的外径过盈配合形成固定联接,芯轴的端部采用旋压铆合结构,旋压铆合结构紧贴内圈的大端面。此结构相对复杂...
