Description
Technical field
A kind of hub is the utility model is related to, more particularly, to a kind of heavy-duty car hub.
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 strength that this hub can be born is smaller, wearability compared with
Difference, positioning is more inaccurate, therefore precision is poor during use.
Utility model content
The utility model is to provide a kind of heavy-duty car hub, and it mainly solves the wheel hub present in prior art
The strength that unit can be born is smaller, and wearability is poor, and positioning is more inaccurate, therefore the technology of the poor grade of precision is asked during use
Topic.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
Heavy-duty car hub of the present utility model, including outer ring, are provided with a pair of inner rings in described outer ring, in two
Lock is fixed between circle, roller is provided between outer ring and inner ring, roller is provided with retainer, between outer ring and the end face of inner ring
Provided with seal assembly, the outer surface of outer ring is provided with gear ring, and the inner surface of outer ring is provided with caulking groove, antifriction alloy is embedded with caulking groove,
Inner surface height of the height of antifriction alloy higher than outer ring.It is inlaid in by antifriction alloy in caulking groove, roller can be caused in work
Abrasion is reduced when making, so as to extend the service life of whole hub.And use can also increase bearing in heavy-duty car
Intensity.Antifriction alloy can be made up of existing more wear-resisting alloying component.
Preferably, being provided with locating slot on described cycle surface, locating slot is provided with step.Locating slot and step can
To be accurately positioned when mounted, so enabling to whole hub, operably precision is higher.
Preferably, being provided with dedusting groove on the outer ring of described roller the inner, width is less than inside it at dedusting channel opening
Width.By the dedusting groove on outer ring, heavy-duty car can be run caused by dust is retained in, reduce the mill of roller
Damage.
Therefore, the utility model is by increasing antifriction alloy, by increasing capacitance it is possible to increase the wearability of roller, and by locating slot with
And dedusting groove can be played and is accurately positioned, coordinate the high effect of precision, it is simple and reasonable for structure.
