A non-contact wheel bearing pre-seal between a wheel carrier (30) on the one hand and a hub (10), a wheel bearing (20) and/or a pivot (40) on the other hand comprises a sealing ring (50) which is fixed on the hub (10), the wheel bearing (20) and/or the pivot (40) and forms a sealing gap together with a mating profile on the wheel carrier (30) or on a component fastened on the wheel carrier (30). The sealing ring (50) has radial bridges (501) between which a chamber (502) is formed. The chambers (502) are each delimited radially on the outside by a retaining wall (503) which in turn delimits the sealing gap radially on the inside in order to generate a flow before and/or in the sealing gap during rotation of the sealing ring (50) which impedes against the seal. The invention further relates to a wheel bearing assembly having such a non-contact wheel bearing pre-seal.

    一种在一方面轮架(30)和另一方面轮毂(10)、轮轴承(20)和/或枢轴(40)之间的非接触式轮轴承预密封件,其包括:密封环(50),该密封环固定在轮毂(10)、轮轴承(20)和/或枢轴(40)处,并且与处于轮架(30)或紧固在轮架(30)处的构件处的配对轮廓一起构造密封间隙。密封环(50)具有径向桥接部(501),在所述径向桥接部之间形成腔室(502)。腔室(502)分别径向在外侧通过挡壁(503)限制,该挡壁自身径向在内侧限制密封间隙,以便在密封环(50)转动时在密封间隙之前和/或在密封间隙中产生阻碍克服密封的流动。此外,说明了一种具有这样的非接触式轮轴承预密封件的轮轴承组件。
