SEAL FOR THE HUBS OF VEHICLE WHEELS

摘要

A seal for bearings of the hubs of vehicle wheels comprises a central body (14) having a seating recess for a spring (15), from which there extends an appendix (16) rigidly connected to a metal insert (18) driven onto the outer race (11) of the bearing; projecting from the appendix (16) is a lip (19) which provides a static seal against the outer race of the bearing, whilst two further lips (22 and 23) project from the body (14) to form a dynamic seal against the toroidally shaped surface (24) of the inner race (10); said lips (22) and (23) are oriented towards the outside of the bearing in order to exploit the centrifugal effect deriving during the operation from the rotation of said surface (24).
