The invention discloses a loader drive axle hub and brake disc assembly. The loader drive axle hub and brake disc assembly comprises a hub and a movable disc face. The hub comprises a planet carrier mounting ring, a rim mounting spigot, a rim bolt mounting hole, a spoke plate, a left bearing mounting seat, a bearing seat outer ring, a right bearing mounting seat and an oil seal mounting seat; thebrake disc face and the hub are formed in an integral casting mode. In order to prevent the bottom of the oil seal mounting position from being too thin to influence the strength of the hub, 135-degree oblique angle transition is adopted at the transition joint of the outer ring of the bearing seat and the brake disc surface; in order to avoid stress concentration, chamfers R are respectively arranged at the root parts of the bevel angle and the bearing seat outer ring and the bevel angle and the brake disc surface for transition. The loader drive axle hub and brake disc assembly is simple instructure, easy and convenient to machine and manufacture, low in cost and safe and reliable to use, the quality of the brake disc can be obviously improved, and the manufacturing cost of the hub andthe brake disc is reduced.
本发明公开了一种装载机驱动桥轮毂与制动盘合件包括轮毂与动盘面;所述轮毂包括行星轮架安装环、轮辋安装止口、轮辋螺栓安装孔、辐板、左轴承安装座、轴承座外环、右轴承安装座和油封安装座;所述制动盘面与轮毂采用整体式铸造而成;为避免油封安装位的底部过薄而影响轮毂强度,在轴承座外环与制动盘面的过渡连接处采用135°的斜角过渡;为避免应力集中,分别在斜角与轴承座外环及斜角与制动盘面的根部设有倒角R过渡。本发明装载机驱动桥轮毂与制动盘合件结构简单、加工制作简便、成本低、使用安全可靠,可明显提升制动盘的质量,减少轮毂与制动盘的制造费用。
