CENTRIFUGAL DISK AS A PRE-SEAL FOR A WHEEL BEARING

摘要

The invention relates to a seal arrangement for a wheel bearing, inserted between a first bearing part and a second bearing part of the wheel bearing, which includes a pre-seal designed as a centrifugal disk and a seal set having sealing lips and a reinforcement. The seal set is attached to the first, torsionally fixed bearing part by a reinforcement which is surrounded at least partially by an elastic sealing material. A radial edge of a centrifugal disk engages with play in an opening that is delimited radially by the sealing material, said centrifugal disk being fixed to the second bearing part via a radial leg and including a catch groove. Together with the seal set, the centrifugal disk forms a seal labyrinth.

1. A seal arrangement of a wheel bearing, which is inserted between a first bearing part and a second bearing part of the wheel bearing, the seal arrangement comprising a pre-seal embodied as a centrifugal disk, and a seal set comprising sealing lips together with a reinforcement, the seal set is connected to the first bearing part via the reinforcement which forms a socket, which is radially defined by an elastic sealing material, and in which a radial edge of the centrifugal disk, which is fixed to the second bearing part and forming which forms a catch groove, engages in the socket while maintaining a seal gap with a degree of play in relation to the seal set, the one-piece centrifugal disk is immovably fixed directly to a radially oriented annular flange of the second, rotatable bearing part by a radial leg and the centrifugal disk forms a seal labyrinth together with the seal set.
