Contact-free wheel bearing pre-seal and wheel bearing arrangement with such a pre-seal

Abstract

A contact-free wheel bearing pre-seal between a wheel carrier, on the one hand, and a wheel hub, a wheel bearing, and/or an axle stub, on the other hand. A sealing ring which is fixed to the wheel hub, the wheel bearing, and/or the axle stub and forms a sealing gap together with a mating contour on the wheel carrier or on a component fastened to the wheel carrier. The sealing ring has radial webs between which cells are formed. The cells are each radially delimited on the outside by a retaining wall, which in turn delimits the sealing gap radially on the inside in order, when the sealing ring rotates, to generate a flow opposed to a breaching of the seal in front of and/or in the sealing gap. There is also disclosed a wheel bearing arrangement with such a contact-free wheel bearing pre-seal.
