The invention relates to a wheel edge structure for supporting and reinforcing a semi-floating axle into a full-floating axle. The wheel edge structure comprises a half shaft, a half shaft bolt, an outer oil seal, a hub, a tire bolt, a brake drum, a brake belt inhaul cable assembly, a bearing nut, a half shaft bearing, a snap spring, an inner oil seal, a rear axle housing assembly, a brake mounting bolt and a nut. A semi-floating axle is optimized into a wheel edge structure of a full-floating axle, the inherent defects that the semi-floating axle is difficult to disassemble and assemble, a half shaft bearing is prone to losing efficacy, an oil seal is prone to being damaged, oil leaks and the like can be fundamentally overcome, maintenance-free wheel ends are achieved, and meanwhile the tire selecting and matching requirements of a single tire and double tires of a whole vehicle are considered. And compared with a semi-floating axle, the practicability and the reliability of the product are greatly improved.
本发明涉及一种支持将半浮式车桥加强为全浮式车桥的轮边结构,其包括半轴、半轴螺栓、外油封、轮毂、轮胎螺栓、制动鼓、制动器带拉索总成、轴承螺母、半轴轴承、卡簧、内油封、后桥壳总成、制动器安装螺栓、螺母。本发明将半浮式车桥优化为全浮式车桥的轮边结构,可以从根本上解决半浮式车桥自身存在的难拆装、半轴轴承易失效、油封易损坏而漏油等固有缺陷,实现轮端免维护,同时兼顾了整车单胎和双胎的轮胎选配需求。相对半浮式车桥,产品的实用性和可靠性大大提高。
