Include flange side surface and long end shaft neck, wherein the outer ring is arranged on the long end shaft neck, can relatively long end-journal from
By rotating；
The diamagnetic interference dust-proof member of hub bearing is arranged between outer ring and flange side surface, including mounting portion, positioning region
And dustproof part；
The mounting portion, dustproof part are in hollow cylindrical, and radius is identical, coaxial arrangement and interconnection；
The mounting portion covers on outer ring and outer ring clearance fit；
The positioning region be arranged in mounting portion on the inner wall of dustproof part side around inside flange, for by with it is outer
Circle edge fits closely the installation accuracy to guarantee the diamagnetic interference dust-proof member of hub bearing；
The dustproof part sets several belt sealing teeth being arranged successively on its side wall, is formed between shutting off between the sealing tooth that goes in ring
Gap and cavity, for being matched with the flange side surface to reduce pollution of the outside contamination source to hub bearing；
The mounting portion, positioning region, dustproof part are all made of magnetic shielding material and are made.
As a kind of diamagnetic further prioritization scheme of interference dust-proof member of automobile hub bearing of the present invention, the mounting portion
The gap cooperated between outer ring is less than or equal to 0.5mm.
As a kind of diamagnetic further prioritization scheme of interference dust-proof member of automobile hub bearing of the present invention, the dustproof part
Belt sealing tooth on the side wall and range in gap is 0.5-1mm between flange side surface.
As a kind of diamagnetic further prioritization scheme of interference dust-proof member of automobile hub bearing of the present invention, the installation
Painting zinc layers are equipped on the outer surface in portion, positioning region and dustproof part.
The invention adopts the above technical scheme compared with prior art, has following technical effect that
The configuration of the present invention is simple, it is easy to make, it can be formed by mold direct pressing；It is ingenious in design, take full advantage of hub spindle
The gap of Internal and external cycle is held, interference of the external magnetic field to internal abs sensor is not only resistant to, and avoids misreading phenomenon, and can completely cut off
Dust；Zinc layers are coated with simultaneously, extend service life.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the partial enlargement diagram at the diamagnetic interference dust-proof member of hub bearing and outer ring, flange side surface cooperation.
In figure, 1- mounting portion, the positioning region 2-, 3- dustproof part, the belt sealing tooth on 4- dustproof part side wall.
Specific embodiment
Technical solution of the present invention is described in further detail with reference to the accompanying drawing:
The present invention can be embodied in many different forms, and should not be assumed that be limited to the embodiments described herein.On the contrary, providing
These embodiments are thoroughly and complete to make the disclosure, and will give full expression to the scope of the present invention to those skilled in the art.
In the accompanying drawings, for the sake of clarity it is exaggerated component.
As shown in Figure 1, the invention discloses a kind of diamagnetic interference dust-proof member of hub bearing, hub bearing include outer ring and
Inner flange, inner flange include flange side surface and long end shaft neck, wherein outer ring be arranged on long end shaft neck, can be opposite
Long end shaft neck is freely rotated；The diamagnetic interference dust-proof member of hub bearing is arranged between outer ring and flange side surface, including installation
Portion, positioning region and dustproof part；Mounting portion, dustproof part are in hollow cylindrical, and radius is identical, coaxial arrangement and interconnection；Peace
