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 the positioning of this hub bearing is more inaccurate, the protection to steel ball compared with
Difference, easily got stuck after the abrasion of outer ring, air-flow operation is not smooth, and 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 energy-efficient automobile hub bearing, and it mainly solves the wheel present in prior art
The positioning that hub axle is held is more inaccurate, and the protection to steel ball is poor, is easily got stuck after the abrasion of outer ring, air-flow operation is not smooth, bearing
Operating efficiency is 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：
Energy-efficient automobile hub bearing of the present utility model, including outer ring, described outer ring are provided with screw, outer ring it is interior
Portion is provided with two inner rings, steel ball is provided between outer ring and inner ring, steel ball is fixed by retainer, the inner surface where steel ball
Provided with arc surface, arc surface has certain gap with steel ball, and circular arc is extended outwardly provided with two-stage step.Outer ring where steel ball
There is certain interval in inner surface, such steel ball can operationally reduce abrasion, have certain scope of activities, pass through two with steel ball
Level step can limit steel ball after outer ring is worn.
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.It can prevent dust from entering inside hub bearing by multiple sealing lips.
Preferably, the inner surface of described outer ring is provided with guiding gutter, guiding gutter is made up of the conical surface and arc surface, guiding gutter
It is located between the inner of inner ring and outer ring.When steel ball at work, cyclone can be produced, rapidly can be arranged cyclone by guiding gutter
Go out, prevent windage, so as to increase service efficiency.
Preferably, it is provided with cushion between retainer on two described inner rings.Two are kept by cushion
Frame relative positioning, it can so ensure the running orbit of steel ball.
Therefore, the utility model is reduced by setting arc surface and step to ensure the operation of steel ball on outer ring
Abrasion, the air current flow of Bearing inner is more smooth, and positioning is more accurate, and operating efficiency is higher, simple and reasonable for structure.
