分享下UDR后桥的小缺陷及自己想的改进方法
先说明:第一次分享这么详细,表达的不易理解,欢迎大家一起讨论(UDR群几年没说话了)先发一下UDR后桥的爆炸图如图UDR的后主动伞齿是没有往差速方向限位的。不像前后独立悬架车那样有差速狗骨杯顶着,不让主动伞齿往被动伞齿顶着(主动伞齿为小伞齿,被动则为大伞齿)
所以UDR是靠被动伞齿顶着主动伞齿来控制齿距(我个人理解是主动伞齿磨损越大,运行的过程中两个伞齿的齿距就在不断的变化,主动伞齿一直前后运动同时被动伞齿附带差速有左右虚位)
所以就会出现图2的磨损。主动伞齿的磨损比被动伞齿大。同时后桥的太阳齿和行星齿的厚度是不一致,有前后的虚位,后蛋蛋安装好后用手能前后推动,运动过程中可能会顶主动伞齿(个人打算加铜套和垫片顶着,参考V牌的OP)

个人猜想UDR行星齿架中间预留了螺丝孔可能是想着上颗螺丝固定伞齿的,但是我实际看了应该没足够的空间用圆头螺丝,沉头螺丝主动伞齿厚度好像也不够

同时差速也有左右的虚位如图(图1对比图2)所以差速真的是在左右晃,个人打算拿15*19的铜垫片解决(目前没有找到更窄的垫片)

铜片垫上的照片有吗
我在纠结铜垫片能不能用来垫轴承https://app.rcfans.com/public/emotion/face_006.png 你还不如在伞齿那打颗沉头螺丝,还好搞点,那正好不是有螺纹吗,应该退不了,除非热变形,正常节约成本,你看slash后面那也是这样搞的,sb设计
