The invention relates to a function integrated hub bearing unit which is mainly composed of a wheel valve assembly, a hub assembly, an inner ring torque transmission shaft, an outer side bearing rolling ring, an outer ring supporting shaft, an inner side bearing rolling ring and an auxiliary function integrated block. An end cover of the wheel valve assembly is fixedly connected with the left end face of the hub assembly, the inner ring torque transmission shaft is formed by connecting a speed reducer main frame and a wheel shaft supporting a bearing inner ring, and the hub assembly is fixedly connected with the speed reducer main frame. The outer surface of the wheel shaft is in interference fit with the inner rings of the outer side bearing rolling ring and the inner side bearing rolling ring; the outer ring supporting shaft is provided with a bearing outer roller path which is connected with the outer side bearing rolling ring and the inner side bearing rolling ring in a matched mode. According to the electric driving wheel, the hollow available space of the high-power inner rotor hub motor is utilized, the structural mode of function multiplexing and space sharing overlapping is adopted, compatibility of torque transmission and load bearing is achieved, optimization of the electric driving wheel bearing structure is improved, and the axial size becomes shorter.

    本发明涉及一种功能集成化的轮毂轴承单元,主要由车轮阀总成、轮毂总成、内圈传扭轴,外侧轴承滚圈、外圈支撑轴、内侧轴承滚圈、辅助功能集成块组成;车轮阀总成的端盖与轮毂总成的左端面固定连接,所述内圈传扭轴由减速器主框架和支撑轴承内圈的轮轴连接而成,轮毂总成与减速器主框架固定连接;轮轴的外表面与外侧轴承滚圈和内侧轴承滚圈的内圈采用过盈配合;所述外圈支撑轴设有轴承外滚道,分别与外侧轴承滚圈、内侧轴承滚圈配合连接。本发明通过利用大功率内转子轮毂电机中空可利用的空间,采用功能复用、空间共用重叠的结构方式,实现了传扭与承重兼容,提高了电驱动轮承载结构的最优化,使轴向尺寸变得更短。
