Abstract
Official abstract text for this publication.
In summary, provided is a wheel bearing unit having a cover element which can be used as a pre-seal to a main seal and encloses the fastening elements of the wheel flange. The outstanding sealing effect has been favored in the past, however a disadvantage in terms of assembly and dismantling is produced which the invention seeks to eliminate. Therefore one or more openings are provided which are formed in the cover. The opening or openings enable the simple dismantling or assembly of the fastening elements on the wheel flange and can advantageously also be closed, such that both the sealing effect and an easy dismantling or assembly are possible.
