Root side, is equipped with ball in the first raceway groove and the second raceway groove, and outer ring passes through two rows of balls with ring flange and inner ring
Connection is rolled, interior retainer is mounted in the first raceway groove, and outer retainer is mounted 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 equipped with and flange
The crimping of disk one, crimping are close to one end of the inner ring；18 balls are housed in the first raceway groove, 20 are equipped in the second raceway groove
Ball；It is additionally provided with speed sensor 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）Comprising ring flange inner ring, flange plate outer ring,
Inside race, ball and retainer, set that there are two outer rollaway nest, ring flange inner ring and inside race outer surfaces on flange plate outer ring inner surface
On be respectively provided with interior rollaway nest corresponding with outer rollaway nest, ball is placed in retainer inscribe between interior rollaway nest and outer rollaway nest, method
There is annular groove and step surface on blue disk inner ring outer surface, be equipped with annular retaining ring in groove, inside race end face is resisted against ring
On shape baffle ring, other end is resisted against on step surface.But this inadequate lighting of bearing unit, induction precision is poor, wheel speed
Transducing signal when sensing is more inaccurate, and data are error-prone, bears to easy to produce fracture when larger gravity, thereby using the service life compared with
It is short.
Utility model content
The utility model is to provide a kind of new-energy automobile two-row ball bearing hub unit, mainly solves the prior art
The inadequate lighting of existing bearing unit, induction precision is poor, and transducing signal when wheel speed senses is more inaccurate, and data easily go out
Mistake bears to easy to produce fracture when larger gravity, thereby using service life shorter equal technical problem.
The above-mentioned technical problem of the utility model is mainly to be addressed by following technical proposals：
The new-energy automobile two-row ball bearing hub unit of the utility model, including ring flange are set on the ring flange
There are inner ring, inner ring to be externally provided with outer ring, ring flange is equipped with crimping, between outer ring and inner ring, is equipped with steel between outer ring and ring flange
Ball, steel ball are equipped with retainer, are connected with the gear ring of zigzag on inner ring, outer ring be equipped with can induction gear ring sensor, flange
It is provided with the first cavity on the end face of disk, the second cavity is provided in the first cavity, the diameter difference of the first cavity and the second cavity is
5-10mm.Two cavitys, which are arranged, in the utility model can ensure the lighting of entire hub unit, so as to adapt to new energy
Automobile.Simultaneously because the diameter difference of the first cavity and the second cavity is restricted to 5-10mm, lightweight can guarantee in this way, and can reach
To due intensity requirement.
Preferably, being equipped with the metallic framework of M types between the outer ring and ring flange root, metallic framework is equipped with close
Sealing, sealing element are equipped with the root of 3 sealing lip engagement flange disks.The metallic framework of M types can make itself and sealing element knot
It is preferable to close even closer, dust-proof effect.
Preferably, the covers disposed on sensor has multiple hemisphere juts, hemisphere jut is towards gear ring.Utilize multiple spherical shapes
Protrusion, can be with the more induction points of induction gear ring, and the data acquired in this way are more accurate.
Preferably, the outer surface of the ring flange contact inner ring is equipped with multiple trapezoidal caulking grooves, it is embedded in trapezoidal caulking groove
There is reinforcement alloy-layer.The wearability of inner ring can be increased using alloy-layer is reinforced, so as to bear larger carrying force.Reinforce
Alloy-layer can be commercially available antifriction alloy and be made.
Therefore, the sensing capability of the utility model is preferable, and transducing signal when wheel speed senses is more accurate, and data are not easy out
Mistake, the more lighting of entire hub unit, parts are not easy to wear, simple and reasonable for structure thereby using lasting a long time.
