A bearing unit for a wheel hub assembly for a motor vehicle, the bearing unit having an axis of rotation and having: two radially outer raceways, a first raceway and a second raceway, the first raceway being a radially outer and axially outer raceway and the second raceway being a radially outer and axially inner raceway; the two radial inner raceways are a third raceway and a fourth raceway, the third raceway is a raceway with the radial inner part and the axial outer part, and the fourth raceway is a raceway with the radial inner part and the axial inner part; the two rows of rolling bodies, namely an axial outer row and an axial inner row, are respectively arranged between the first roller path and the third roller path and between the second roller path and the fourth roller path; at least one raceway provided with a first raceway portion (20o ') and a second raceway portion (20o' '), both the raceway portions being tangent to the rolling bodies in the row of rolling bodies at two different contact angles, a first contact angle (CAO') of the first raceway being smaller than a second contact angle (CAO '') of the second raceway portion.
一种用于机动车辆用的车轮轮毂组件的轴承单元,轴承单元具有旋转轴线且具有:两个径向外滚道,即第一滚道和第二滚道,第一滚道为径向外部且轴向外部的滚道,第二滚道为径向外部和轴向内部的滚道;两个径向内滚道,即第三滚道和第四滚道,第三滚道为径向内部且轴向外部的滚道,第四滚道为径向内部且轴向内部的滚道;两列滚动体,即轴向外列和轴向内列,分别介于第一滚道与第三滚道之间以及第二滚道与第四滚道之间;至少一个滚道,设置有第一滚道部(20o')和第二滚道部(20o"),滚道部两者以两个不同的接触角与滚动体列中的滚动体相切,第一滚道的第一接触角(CAO')小于第二滚道部的第二接触角(CAO")。
