Description
Technical field
A kind of automobile hub unit is the utility model is related to, more particularly, to a kind of Lightweight car wheel hub unit.
Background technology
With the development of technology, the integrated level more and more higher of automobile hub bearing.Automobile using bearing unit typically wraps
Inner ring, outer ring are included, single-row or biserial roller are fixed with by retainer between Internal and external cycle.Chinese patent discloses a kind of wheel hub
Bearing unit（Authorization Notice No.：CN201671960U）, it includes ring flange, inner ring, outer ring, ball, interior retainer, outer holding
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 volume of this hub is larger, spent material is more,
Heavier-weight, therefore cause the heavier-weight of automobile after assembling, and run and relatively have some setbacks, sealing property is poor.
Utility model content
The utility model is to provide a kind of Lightweight car wheel hub unit, and it mainly solves the wheel present in prior art
The volume of hub unit is larger, and spent material is more, heavier-weight, therefore causes the heavier-weight of automobile after assembling, and
Operation relatively has some setbacks, the technical problem of the poor grade of sealing property.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
Lightweight car wheel hub unit of the present utility model, including ring flange, described ring flange be provided with outer ring with it is interior
Circle, is provided with steel ball between outer ring and inner ring, steel ball is located on retainer, and outer ring is provided with gear ring, gear ring connection sensor, flange
Disk is generally cross, and the corner of ring flange is provided with slope, and ring flange is connected with screw rod.Opened up on ring flange tiltedly
Slope, the weight of hub can be greatly decreased, so that automobile can be with lightweight.
Preferably, described inner ring is inner to be provided with breach, oiling groove is provided with the ring flange where indentation, there.Breach can
So that automotive light weight technology, breach coordinates with oil storage tank, can accommodate more lubricating grease, can so ensure that hub is run
Ground is more smooth.
Preferably, being provided with the cavity of arc on the end face of described ring flange, the outer surface of outer ring is provided with groove, groove
It is interior to be provided with some reinforcements.Automotive light weight technology can further be made by opening up cavity, groove, and can be ensured using reinforcement whole
The intensity of individual hub.
Preferably, the inner of described outer ring is provided with the metalwork of C fonts, seal is connected with metalwork, is sealed
Part is provided with the root of 3 sealing lip engagement flange disks.
Therefore, the utility model utilizes and reduces material on ring flange, outer ring so that the material spent by whole hub
Expect less, the more lightweight of whole hub, sealing property is preferable, and operation is more smooth, and operating efficiency is higher, structure letter
It is single, reasonable.
