The invention discloses a flanged inner ring for a wheel hub bearing; a tubular support body for the bearing being coaxial with the axis and provided with a flange transverse to the axis, provided with a plurality of threaded through holes and delimited in the axial direction by an outer annular mounting surface and an inner surface facing the outer ring of the bearing in the axial direction, thisdetermines a respective base axial thickness of the tubular support body for each threaded through-hole a radial arm is positioned on the inner surface of the flange and at a position facing the outer ring; the radial arm extends outwards from the shoulder part in the radial direction and is used for reinforcing the flange, and the corresponding axial thickness of the shoulder part is greater than that of the flange; the inner ring is made into an integrated piece by forging the flange, the shoulder part and the radial arm; a first ratio between the axial thickness of the flange and the axialthickness of the shoulder portion is valued in a range between a minimum 0.15 and a maximum 0.4, and a second ratio between the axial thickness of the flange and the diameter of the flange is valuedin a range between a minimum 0.018 and a maximum 0.03.
一种用于车轮轮毂轴承的带凸缘的内圈,用于轴承的管状支撑主体与轴线同轴并且设置有横向于轴线的凸缘,设置有多个螺纹通孔,并且在轴向上由外环形安装表面和在轴向上面向轴承的外圈的内表面界定,这确定管状支撑主体的相应的基础轴向厚度,对于每个螺纹通孔,径向臂定位在凸缘的内表面上且位于面向外圈的位置;径向臂从肩部在径向上向外延伸,设置用于增强凸缘,肩部的相应的轴向厚度大于凸缘的轴向厚度;内圈通过锻造制成使凸缘、肩部和径向臂成一体件;凸缘的轴向厚度与肩部的轴向厚度之间的第一比在最小0.15至最大0.4之间的范围内取值,凸缘的轴向厚度与凸缘的直径之间的第二比的值在从最小0.018至最大0.03之间的范围内取值。
