Description
Technical field
This utility model is related to a kind of automotive hub parts, forges flower-shape flange more particularly, to a kind of electric automobile.
Background technology
With the development of technology, the integrated level more and more higher of automobile hub bearing.Automobile bearing unit is typically wrapped
Inner ring, outer ring are included, single-row or biserial roller has been fixed with by retainer between Internal and external cycle.Chinese patent discloses a kind of wheel hub
Bearing unit（Authorization Notice No.：CN201671960U）, which includes ring flange, inner ring, outer ring, ball, interior retainer, outer holding
Frame, inner ring are arranged on the end outside ring flange；Outer ring is arranged on the root outside ring flange, outer ring and ring flange and inner ring it
Between be provided with first raceway groove and the second raceway groove of ring-type, in ring flange end side, the second raceway groove is in ring flange root for the first raceway groove
Side, is provided with ball in the first raceway groove and the second raceway groove, and outer ring is rolled by two row's balls with ring flange and inner ring and is connected, interior
Retainer is arranged in the first raceway groove, outer retainer is arranged in the second raceway groove, the second raceway groove with diameter greater 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 provided with the crimping with ring flange one, volume
While being close to one end of the inner ring；, built with 18 balls, the second raceway groove is built with 20 balls for first raceway groove；Also set outside inner ring
There is speed sensor, speed sensor includes magnetic induction head and alloy tooth annulus.Chinese patent also discloses a kind of automotive wheels
Hub bearing unit（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, be respectively provided with ring flange inner ring and inside race outer surface with outward
The corresponding interior raceway of raceway, ball are placed in retainer inscribe and are located between interior raceway and outer raceway, ring flange inner ring appearance
There is on face annular groove and step surface, annular retaining ring in groove, is provided with, inside race end face is resisted against on annular retaining ring, another
End face is resisted against on step surface.But the intensity of these automobile hub units is poor, abrasion is more serious, and service life is shorter,
And positioning is more inaccurate, and transmission efficiency is relatively low.
Utility model content
This utility model is to provide a kind of electric automobile forging flower-shape flange, and which is mainly solved existing for prior art
The intensity of automobile hub unit is poor, and abrasion is more serious, and service life is shorter, and position it is more inaccurate, transmission efficiency compared with
Low technical problem.
What above-mentioned technical problem of the present utility model was mainly addressed by following technical proposals：
Electric automobile of the present utility model forges flower-shape flange, including ring flange body, and the one of described ring flange body
End is provided with ring flange, and the root of ring flange body is provided with step, and the outer of ring flange is encompassed at flower pattern, and each petal
A through hole is provided with, the inwall of through hole is provided with alloy-layer, and alloy-layer is inlaid in through hole, and axis hole is provided with ring flange body.
The intensity of whole through hole can be strengthened by alloy-layer so as to more wear-resisting in assembling.And can be with according to wear intensity
Alloy-layer is arbitrarily changed, the cost of whole electric automobile is which decreased.Alloy-layer can be the wear-resisting alloy of commercially available comparison
Material is made.
Preferably, the inwall of described axis hole is provided with location fin, location fin is arranged into divergence form.By positioning
Fin can ensure that assembling in place, prevent parts from beating.
Preferably, the two ends of described ring flange body are provided with horn mouth, bootstrap block at horn mouth, is provided with, bootstrap block
Outer end is provided with chamfering.Easily other parts can be loaded by bootstrap block.
Therefore, this utility model arranges alloy-layer in the through hole of flower pattern can strengthen the intensity of whole flange, in axis hole
Fin is set, it is ensured that the parts of assembling will not be beated, and transmission efficiency is higher, simple and reasonable for structure.
