Description

一种轴套式十字轴
技术领域
本实用新型及车辆零部件的传动轴,尤其是一种轴套式十字轴。
背景技术
现有车辆中的万向节十字轴,其结构是在十字轴架的四个轴头上装配滚针轴承及轴承座的形式,并且轴承座为两段分体组装结构形式,其缺点是结构复杂,安装不方便,容易磨损,需要经常加注黄油润滑。
发明内容
本实用新型的目的就是要克服现有传动十字轴结构复杂,安装不方便,容易磨损,需要经常加注黄油润滑等问题提供一种新型的轴套式十字轴。
本实用新型的具体方案是:针对现有的十字轴进行改进,它具有十字轴架,十字轴架内开有十字油道,并在十字轴架内开有进油道连通十字油道,在四个轴头上各自均套装有密封圈、轴套及轴套座,其特征是:在每个轴头的后端设有止挡轴肩,轴头前端呈台阶结构,在轴套的内圆面开有若干油槽;所述密封圈顶住轴头的止挡轴肩安装,所述轴套与轴头间隙装配,轴套与轴套座过盈装配,轴套座与轴头台阶面构成储油室,所述轴套上的油槽与储油室构成连通。
本实用新型中所述的轴套座外壁下段设有微小台阶面,台阶高度为0.5mm,轴套座内壁上端设有内台阶,内台阶高度为0.5mm,内台阶端面顶住轴套端面安装;并且轴套座内壁的小直径段长度等于轴头前端的小直径段长度。
本实用新型中所述轴头止挡轴肩外圆直径≤密封圈外圆直径。
本实用新型中所述的密封圈采用减震密封圈。
本实用新型中所述的轴套座为整体式结构。
本实用新型中所述的十字轴架上,每个轴头的前端上开有若干油槽,该油槽与储油室连通。
本实用新型由于增设了储油室,使轴套与十字轴之间始终保持较好的润滑状态,耐磨耐用,提高了十字轴的使用寿命;并且本实用新型采用减震密封圈,密封效果良好,又无异响;本实用新型还具有结构简单、安装方便、无需经常加注润滑油等特点。
附图说明
