Bearing and a kind of wheel hub for motor vehicle of the method for installation into motor vehicle hub

摘要

In the present invention,It is disclosed a kind of installation automobile hub bearing,It the described method comprises the following steps::(One)Under exterior cylindrical surface( 8 )Bear( 1 )In cylindrical base( 9 )With(Two)The tubular portion of cold deformation( 17 )Cylindrical seat( 9 ),Wherein when press-in cooperation exterior cylindrical surfaces( 8 )Bear( 1 )In cylindrical base( 9 )Ring( 19 ),It can flexibly be compressed,It axially compresses in the axial direction,One of between two side surfaces( 12,13 )Outer ring( 3 )Bear( 1 )With the tubular portion in cold deformation( 17 ),The ring( 19 )Between be axially compressed outer ring( 3 )Bear( 1 )And shoulder( 11 )Or( 18 )Distortion wheel rim seat( 9 ),To compensate on relative thermal expansion polar bear and seat between any. A kind of for motor vehicle hub-bearing unit is also disclosed, ring (19) are arranged in the battery unit, it can flexibly be compressed, one of in the axial direction between two side surfaces (12,13) outer ring (3) bear (1) and shoulder (11) or (18) distortion wheel rim cylindrical base (9).
