Side is equipped with ball in the first raceway groove and the second raceway groove, and outer ring is rolled by two rows of balls with ring flange and inner ring and connected, 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 first raceway groove
Diameter, the ball in the second raceway groove is more than the ball in the first raceway groove；Ring flange end is equipped with the crimping with ring flange one, volume
While it is close to one end of inner ring；Equipped with 18 balls in first raceway groove, the second raceway groove is interior to be equipped with 20 balls；Speed is additionally provided with outside inner ring
Inductor is spent, speed sensor includes magnetic induction head and alloy tooth annulus.Chinese patent also discloses a kind of automotive wheels hub axle
Bearing unit（Authorization Notice No.：CN201401445）, including ring flange inner ring, flange plate outer ring, inside race, ball and holding
Frame is set on flange plate outer ring inner surface there are two outer rollaway nest, is respectively provided on ring flange inner ring and inside race outer surface and outer rollaway nest
Corresponding interior rollaway nest, ball are placed in retainer inscribe between interior rollaway nest and outer rollaway nest, on ring flange inner ring outer surface
With annular groove and step surface, annular retaining ring is equipped in groove, inside race end face is resisted against on annular retaining ring, other end
It is resisted against on step surface.But these automobile hub units intensity in assembling is relatively low, service life is shorter, positioning it is inaccurate and
Abrasion resistant effect is poor, and transmission efficiency is relatively low.
Utility model content
The utility model is to provide a kind of outer ring forging used for electric vehicle, mainly solves the vapour present in the prior art
Wheel hub unit intensity in assembling is relatively low, and service life is shorter, and positioning is inaccurate and abrasion resistant effect is poor, and transmission efficiency is relatively low
The technical issues of waiting.
The above-mentioned technical problem of the utility model is mainly what is be addressed by following technical proposals：
A kind of outer ring forging used for electric vehicle of the utility model, including outer ring ontology, the outer ring ontology is equipped with disk
Body, the both ends of outer ring ontology have big cavity and areola, locating slot, the bottom surface of locating slot and disk body are evenly equipped on outer ring
The angle of end face be 4-6 °, the outer surface of outer ring ontology and the angle of horizontal plane are 2-4 °, the side wall of big cavity and vertical plane
Angle is 82-88 °, and the angle of areola side wall and vertical plane is 76-82 °.By the angle to locating slot and outer ring ontology, big
The angle setting of cavity, areola so that most save and can ensure strong in the material of these angular range Internal and external cycle forging
Degree.
Preferably, the corner of the disk body and outer ring ontology is equipped with the caulking groove of crescent, it is equipped with and strengthens in caulking groove
Alloy-layer.It can strengthen the intensity of disk body root using alloy-layer is strengthened, larger shearing force can be born.Strengthening alloy-layer can be with
Antifriction alloy is commercially available to be made.
Preferably, the bottom surface of the big cavity is equipped with serrated slot, fin is equipped in serrated slot.Using serrated slot and
Fin can allow outer ring forging preferably to be connect in following process with other components.
Preferably, the inside of the areola is equipped with orientational cone-shaped surface.When can cause assembling using orientational cone-shaped surface
Play the role of accurate positioning.
Therefore, the utility model sets each angle on outer ring, and the material of entire outer ring can be greatly decreased, and protects
Intensity is demonstrate,proved, enables to assembly precision higher by a variety of detent mechanisms, extends the service life of outer ring, improves wearability, is passed
Efficiency of movement is higher, simple and reasonable for structure.
