A hub bearing unit includes a hub rotatable about an axis and having a flange connectable with a wheel, a ball inner raceway, and a roller inner raceway. An outer ring may be connected to the vehicle and disposed about the hub, and has a ball outer raceway and a roller outer raceway. A plurality of balls roll on the ball inner raceway and the ball outer raceway, and a plurality of tapered rollers roll on the roller inner raceway and the roller outer raceway. The contact angle between the ball and the ball raceway has a value between 10 degrees and 40 degrees. Each line extending through the in-ball contact point and the out-ball contact point intersects a line extending through the roller midpoint circle at an apex, the apex being spaced apart from a midpoint of a spacing line segment that is a spacing line segment between a ball pitch circle and a roller pitch circle by an axial distance of no greater than 7.5 mm.

    一种轮毂轴承单元,包括轮毂,所述轮毂可绕着轴线旋转并且具有可与轮连接的凸缘、球内滚道和滚子内滚道。外圈可与车辆连接,并且绕着所述轮毂布置,并且具有球外滚道和滚子外滚道。多个球在所述球内滚道和所述球外滚道上滚动,并且多个圆锥滚子在所述滚子内滚道和所述滚子外滚道上滚动。所述球与所述球滚道之间的接触角具有在10度与40度之间的值。延伸穿过球内接触点和球外接触点的每条线与延伸穿过滚子中点圆的线在顶点处相交,所述顶点和间隔线段的中点间隔开不大于7.5毫米的轴向距离,所述间隔线段为球节圆与滚子节圆之间的间隔线段。
