The invention discloses a wheel bearing structure with a gasket, which relates to the field of automobile parts and comprises a flange plate and the like, an inner ring is mounted on the flange plate in a clamping groove manner, an outer ring is sleeved on the flange plate, an inner raceway is arranged between the inner ring and the outer ring, an outer raceway is arranged between the journal root of the flange plate and the outer ring, and the inner raceway and the outer raceway form a double-row raceway; a spin riveting outer diameter is arranged on the side, close to the inner ring, of the flange plate, and a gasket is riveted to the spin riveting outer diameter through the spin riveting technology. A shaft hole is formed in the center of the gasket for a driving wheel spline half shaft to penetrate, and a flange is arranged along the outer edge of the gasket; at least three protruding points are evenly distributed on the flange along the circumference, and the protruding points are matched with a concave area on the outer diameter of the spin rivet to form a lock catch type structure. The technical problem that the vehicle performance is reduced due to the fact that the hardness of the surface, attached to the constant-speed half shaft, of the wheel bearing is insufficient can be solved; and meanwhile, the technical problem of abnormal sound of the vehicle caused by insufficient wear resistance of the surface, attached to the constant-speed half shaft, of the wheel bearing is solved.
本发明公开了一种带垫片车轮轴承结构,涉及汽车零部件领域,包括法兰盘等,法兰盘上卡槽式安装有内圈,外圈套装在法兰盘上,内圈与外圈之间设置内侧滚道,法兰盘的轴颈根部与外圈之间设置外侧滚道,内、外侧滚道组成双列滚道;法兰盘上靠近内圈的一侧设有旋铆外径,旋铆外径上通过旋铆工艺铆接有垫片;垫片的中心开设轴孔供驱动轮花键半轴穿入,沿垫片的外边缘设置有翻边;翻边上沿圆周均布有至少三个凸点,凸点与旋铆外径上的凹陷区域配合形成锁扣式结构。本发明能够解决车轮轴承上与等速半轴贴合面部位硬度不足导致车辆性能下降的技术难题;同时解决车轮轴承上与等速半轴贴合面部位耐磨不足导致车辆异响的技术难题。
