Document Type and Number:
WIPO Patent Application WO/2020/040444
Kind Code:
A1
Abstract:
The present invention relates to an encoder seal assembly for sealing between an outer ring and an inner ring of a hub bearing for a vehicle, wherein the hub bearing has coupled thereto an encoder for detecting the rotational speed of an axle. The encoder seal assembly comprises a main rib, on which a plurality of contact protrusions are formed, and a labyrinth rib which guides introduced foreign matter to flow in the direction in which the foreign matter is introduced. Therefore, in the encoder seal assembly, constant contact stress is maintained on the main rib according to the pressure of the introduced foreign matter, the frictional loss of the seal assembly is minimized while at the same time leakage of foreign matter to the inside is prevented, thereby improving sealing, and errors of existing encoders are reduced such that high-quality measurement is possible.
