Description

带3列角接触球轴承的轮毂单元
技术领域
本实用新型涉及一种汽车用轮毂轴承，特别涉及一种带3列角接触球轴承的轮毂单元。
背景技术
轮毂轴承的主要作用是承重和为轮毂的转动提供精确引导，它既承受载重又兼有负责引导转向的功能，因此无论是在轴向还是在径向上都有很大的负荷。传统的双列角接触球轴承能承受较大的径向负荷，主要为径向和轴向联合负荷和力矩负荷，用于限制轴和外壳的双向轴向位移。根据以往的轴承试验结果发现，靠近芯轴的沟道将会承载更大的载荷，易损坏，且所能承受的轴向载荷较小。传统的双列圆锥滚子轴承，可以承受较大的径向载荷和轴向载荷，但滚子与挡边的摩擦较大，耗能大，能源利用率低。
发明内容
本实用新型所要解决的技术问题是提供一种带3列角接触球轴承的轮毂单元，不仅承载能力强，且油耗省，使用寿命长。
本实用新型解决问题采用的技术方案是：一种带3列角接触球轴承的轮毂单元，包括外圈、内圈、芯轴、钢球、保持架，所述内圈上设有一个沟道，所述芯轴上设有两个沟道，所述外圈上分别设有与内圈上及芯轴上所设沟道相对应的三个沟道，所述每对沟道内设置钢球。
本实用新型在现有带2列角接触球轴承轮毂单元基础上，通过无滑移纯滚碾芯轴的端面，压住内圈，使整个轮毂有一定的预紧力；并在靠近芯轴一端增加一列钢球，使其无论在径向还是轴向上都具有更大的承载力，延长轮毂单元的使用寿命。本实用新型适用车重、车载更大的轿车、轻卡、小型载货车、面包车等车型。
本实用新型的有益效果是：一边采用2个沟道，等同于圆锥滚子轴承，采用球的点接触代替了圆锥与滚道的线接触，使摩擦减少25％，即意味着轴承运转时的温度更低，提高了轴承润滑脂的使用寿命，与圆锥滚子相比，车子在转弯时的刚性也更好；再增加1列钢球的设计使得汽车在承载力上大大提升，并能有效的节省油耗，结构上更为合理和紧凑，使用寿命更长。
附图说明
图1为本实用新型实施例的剖视结构示意图。
图2为图1所示本实用新型实施例的左视结构示意图。
下面结合附图对本实用新型做进一步说明：
具体实施方式
结合图1、图2所示，一种带3列角接触球轴承的轮毂单元，包括外圈1、内圈2、芯轴3、钢球6、保持架7，在内圈2上设有一个沟道，芯轴3上设有两个沟道，外圈1上分别设有与内圈2上及芯轴3上所设沟道相对应的三个沟道，在三对沟道内都设有钢球6，钢球6由保持架7固定；密封装置4和密封件9使整个工作部位形成了一个密封系统，防止轮毂轴承进水，且不受灰尘影响，防止油脂外流。
本实用新型为悬架上的传动部件，外圈1通过螺栓5固定在悬架上，芯轴3通过花键与球笼连接到传动轴上，形成传动扭矩的的结构。
