The invention discloses a hub unit for a wheel-side motor, and relates to the field of wheel-side motors. The hub unit comprises a bearing inner ring, a hub outer ring and a flange plate; the flange plate is movably sleeved with the hub outer ring; a bearing inner ring which is nested with the flange plate in a clamping groove type limiting manner is arranged between the hub outer ring and the flange plate; an outer side roller path is arranged between the root of a journal of the flange plate and the hub outer ring; the outer side roller path and an inner side roller path arranged between thebearing inner ring and the hub outer ring form a double-row roller path used for installing a bearing rolling body; a retainer covers the bearing rolling body to fix the bearing rolling body; the bearing inner ring and the hub outer ring are connected and sealed through a magnetic sealing assembly; the flange plate and the hub outer ring are connected and sealed through a sealing assembly; and adeep groove ball bearing is arranged in the flange plate and is connected with a driving shaft. Through the structural design, the obtained novel hub unit for the wheel-side motor can bear the maximumtorque larger than or equal to 800 Nm, the transmission performance of the bearing unit is effectively enhanced, the integration degree is increased, and the installation difficulty is lowered.

    本发明公开了一种轮边电机用轮毂单元,涉及轮边电机领域,包括轴承内圈、轮毂外圈和法兰盘,所述轮毂外圈活动式套装在法兰盘上,该轮毂外圈与法兰盘之间设有与法兰盘向卡槽式限位嵌套的轴承内圈;法兰盘轴颈根部与轮毂外圈之间设置外侧滚道,该外侧滚道与设置在轴承内圈和轮毂外圈之间的内侧滚道组成双列滚道,用于安装轴承滚动体,保持架罩设在轴承滚动体外将其固定;轴承内圈与轮毂外圈之间通过磁性密封组件连接密封,法兰盘与轮毂外圈之间通过密封组件连接密封;法兰盘内设有深沟球轴承用于连接驱动轴。本发明通过结构设计,获得的新型轮边电机用轮毂单元可承受最大扭矩≧800Nm,有效增强轴承单元的传动性能,提升集成度,降低安装难度。
