Frame, inner ring are arranged on the end outside ring flange；The outer ring is arranged on the root outside ring flange, outer ring and ring flange and interior
The first raceway groove and the second raceway groove of ring-type are provided between circle, the first raceway groove is in ring flange end side, and the second raceway groove is in ring flange
Root side, is provided with ball in the first raceway groove and the second raceway groove, and outer ring passes through two described row's balls with ring flange and inner ring
Connection is rolled, interior retainer is arranged in the first raceway groove, and outer retainer is arranged in the second raceway groove, and the diameter of the second raceway groove is more than
The diameter of first raceway groove, the ball in the second raceway groove is more than the ball in the first raceway groove；Ring flange end is provided with and flange
The crimping of disk one, crimping are close to one end of the inner ring；First raceway groove is built with 18 balls, and the second raceway groove is built with 20
Ball；Speed sensor is additionally provided with outside inner ring, speed sensor includes magnetic induction head and alloy tooth annulus.Chinese patent is also public
A kind of automobile hub bearing is opened（Authorization Notice No.：CN201401445）, it include ring flange inner ring, flange plate outer ring,
Inside race, ball and retainer, flange plate outer ring inner surface are provided with two outer raceways, ring flange inner ring and inside race outer surface
On be respectively provided with the interior raceway corresponding with outer raceway, ball is placed in retainer inscribe between interior raceway and outer raceway, method
There is annular groove and step surface on blue disk inner ring outer surface, be provided with annular retaining ring in groove, inside race end face is resisted against ring
On shape back-up ring, other end is resisted against on step surface.But this hub bearing does not integrate gear ring, the positioning to gear ring is less
Accurately, and retainer easily moves, and sealing property is poor, causes that the operating efficiency of bearing is relatively low, and energy consumption is larger.
Utility model content
The utility model is to provide a kind of automobile hub bearing of integrated gear ring, and it is mainly solved present in prior art
Hub bearing not integrate gear ring, the positioning to gear ring is more inaccurate, and retainer easily moves, and sealing property is poor,
Cause the operating efficiency of bearing relatively low, the technical problem of the larger grade of energy consumption.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
The automobile hub bearing of integrated gear ring of the present utility model, including outer ring, wear on described outer ring and be connected to bolt, outside
The inside of circle is provided with two inner rings, and steel ball is provided between outer ring and inner ring, and two row steel balls pass through interior retainer, outer retainer respectively
Fixed, the outer surface of outer ring is provided with mounting surface, and mounting surface is less than the outer surface of outer ring, and it is " several " word to be integrated with section in mounting surface
The gear ring of type, the inner of mounting surface are provided with arc surface, and the part that gear ring end upwarps has at regular intervals with arc surface.Gear ring collection
It is more convenient on outer ring, so installing, because gear ring end upwarps, there is certain distance with the arc surface of outer ring, so
Using gear ring has certain ductility.
Preferably, being provided with seal assembly between the outer end of described outer ring and inner ring, it is L that seal assembly, which includes section,
The interior metallic framework of type and outer metallic framework, interior metallic framework are provided with seal, and two sealing lips contact on seal is outside
Metallic framework, seal middle part are provided with breach, and indentation, there is provided with spring, and the spring other end is withstood on sealing lip.Can by spring
To compress sealing lip, after such usage time one is grown, sealing lip also will not depart from metallic framework because of aging.
Preferably, cushion is provided between described interior retainer and outer retainer.Two are kept by cushion
Frame relative positioning, it can so ensure the running orbit of steel ball.
Preferably, the bottom of described mounting surface is provided with serrated slot, bolster is embedded with serrated slot.Utilize bolster
On the one hand it can play a part of shielding the magnetic line of force, on the other hand can increase its frictional force with gear ring, reach registration
Effect.
Therefore, hub bearing of the present utility model integrates gear ring, and the positioning to gear ring is more accurate, and retainer is not easy
Mobile, sealing property is preferable so that the operating efficiency of bearing is higher, and energy consumption is smaller, simple and reasonable for structure.
