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 the oiling performance of this hub unit is poor, wheel hub usage time one
After length, parts easy to produce abrasion, are easy aging, shorter thereby using the service life.
Utility model content
The utility model is to provide a kind of direct-oiling hub unit, mainly solves the wheel present in the prior art
The oiling performance of hub unit is poor, and after wheel hub usage time one is grown, parts easy to produce abrasion, is easy aging, 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 direct-oiling hub unit of the utility model, including outer ring, set that there are two inner ring, outer rings in the outer ring
Roller is equipped between inner ring, roller is equipped with retainer, and oblique on outer ring to be provided with oil duct, oil duct outer end is connected with oil nozzle, oil
The inner surface in road is equipped with spiral fin, is provided on fin and angularly disposed divides oil groove.The utility model passes through directly outside
Oil nozzle is added on circle, it can be directly toward oiling in hub unit, to ensure the greasy property inside hub unit.It is set in oil duct
Fin is set, the flow velocity of lubricating oil can be accelerated, and opens up point oil groove and grease can be more rapidly passed into hub unit
Portion.
Preferably, the interior metallic framework between the outer ring and inner ring equipped with L-type and outer metallic framework, interior metal bone
Rubber seal is connected on frame, there are three sealing lips to contact outer metallic framework for rubber seal tool.Since the utility model is
Direct-oiling, it is therefore desirable to which three sealing lips stop that fluid leaks.
Preferably, the end face corner of the outer ring is equipped with outer ring metallic framework, outer ring metallic framework is equipped with three
The outer ring sealing element of forked type.Sealing can be further functioned as using the outer ring sealing element of Trident Type when entire hub unit is assembled
Effect.
Preferably, outer ring where the roller, indwelling slot is designed on the bottom surface of inner ring, at indwelling channel opening
Width is less than its inner width.In a part of lubricating oil being stored in using indwelling slot, so as to constantly to wheel hub list
First internal make-up oil.
Therefore, the oiling better performances of the hub unit of the utility model, can direct oiling, parts are not easy to produce
Abrasion, it is non-aging, it is simple and reasonable for structure thereby using lasting a long time.
