Abstract:
A steering knuckle, which is provided for receiving an outer ring of a wheel bearing, and a wheel bearing arrangement with such a steering knuckle. The sealing arrangements of the wheel bearing has a pre-seal, which is designed as a labyrinth seal to provide sealing for an appropriate gap geometry. To this end, the steering knuckle has a collecting channel, which captures liquids and dirt particles and discharges them at the periphery. The hearing seal can be changed by this measure, so that savings are possible with a minimum of sealing action of the conventional sealing arrangement and with greatly reduced friction torque. Overall, the sealing action, which is now achieved by the bearing seal and the pre-seal together, is increased or remains at least at the same level while manufacturing costs are reduced.
