The invention discloses an end face spline type hub bearing unit, and relates to the field of hub bearings. The end face spline type hub bearing unit comprises an outer ring, an inner ring, a flange plate and an end face spline, an outside roller path is arranged between the shaft neck root of the flange plate and the outer ring of a hub bearing, the outside roller path and an inside roller path arranged between the inner ring and the outer ring form a double roller path, a roll rim is arranged at the side, close to an inner side sealing ring, of the flange plate, and the end face spline is arranged on the side end face and used for being directly connected with a drive shaft. The end face spline type hub bearing unit has the beneficial effects that the end face spline of the hub bearing unit can be connected with the drive shaft, is used as a transmission device for torque transmission to lift a drive torque, and compared with existing inner spline transmission, torque driving is obviously improved; the full vehicle NVH performance is effectively improved, the disassembly and disassembly convenience in the full vehicle production and maintenance process is improved, the weight ofthe hub bearing is reduced, and light weight is realized; and the hub bearing with end face spline teeth can effectively eliminate drive clearances, and eliminate drive abnormal sound.

    本发明公开了一种端面花键型轮毂轴承单元,涉及领域轮毂轴承,主要包括外圈、内圈、法兰盘和端面花键,法兰盘的轴颈根部与轮毂外圈之间设置外侧滚道,与设置在内圈和外圈之间的内侧滚道组成双列滚道,法兰盘靠近内侧密封环的一侧带有卷边,且在该侧端面上设置有端面花键用于直接连接驱动轴。本发明的有益效果为:该轮毂轴承单元端面花键,可与驱动轴连接,作为传动装置进行扭矩传输,提升驱动扭矩,与现有内花键传动的相比驱动扭矩显著提升;有效改善整车NVH性能,提高整车生产及维修过程中的装配、拆卸方便性,减轻轮毂轴承重量,实现轻量化;带有端面花键齿的轮毂轴承能够有效消除驱动间隙,消除驱动异响。
