車輪用軸受装置
Document Type and Number:
Japanese Patent JP2008528878
Kind Code:
A
Abstract:
A vehicle wheel bearing apparatus that protects the encoder, improves the sensing ability of the detecting sensor, prevents penetration of rain water or dust, and prevents leakage of differential gear oil has an inboard side seal ( 13 ) with an annular supporting plate ( 17 a) fit onto the outer circumferential surface of one of the inner rings ( 10 ). A purser ring ( 17 ), having an encoder ( 17 b), is bonded on the outer circumferential surface of the supporting plate ( 17 a). A sealing plate ( 16 ), including an annular core member ( 18 and 22 ), is fit onto one end of the outer member ( 4 ) and covers the cylindrical portion of the encoder ( 17 b). A lip ( 19 a) is bonded on the core member ( 18 and 22 ) and is in sliding contact with the inner ring ( 10 ). A detecting sensor ( 20 ) is suspended from an axle housing "H" and opposes the encoder ( 17 b) via a predetermined radial gap. Sealing lips ( 18 b and 19 c) on the sealing plate 16 are arranged between the core member ( 18 and 22 ) and the axle housing "H" to seal the detecting sensor ( 20 ).
