Abstract
The utility model provides a kind of hub bearing, and it is by flange outer ring, flange inner ring, little inner ring, steel ball, retainer, magnetic circle, outer side seal, boss bolt, metal end, and O type circle forms.Wherein said metal end and flange outer ring adopt interference fit in order to by inside bearing and external isolation.The hub bearing that the utility model relates to has good bearing seal, can reduce intrusion and the corrosion of foreign matter, makes bearing have longer working life.Meanwhile, owing to eliminating traditional inner seal structure, what make bearing drags reduction, adds the fuel economy of vehicle.
Description
Technical field
The utility model relates to field of bearings, especially, relates to a kind of hub bearing.
Background technique
Typically, traditional hub bearing generally adopts medial and lateral double sealing structure 32,34, as shown in Figure 3.This structure makes foreign can be relatively easy to invade Bearing inner, thus the lubrication of bearing is declined, and easily causes corrosion.Like this, the working life of bearing will be reduced, and then cause and complain after sale.
Therefore, be necessary very much to propose a kind of novel hub bearing, overcome defect of the prior art.
Model utility content
The purpose of this utility model is to provide a kind of hub bearing, and it can have better bearing seal, to reduce intrusion and the corrosion of foreign matter, makes bearing have longer working life.
To achieve these goals, the technical solution adopted in the utility model is as follows.
A kind of hub bearing, it includes boss bolt, flange inner ring, outer side seal, steel ball, little inner ring, magnetic circle, retainer and flange outer ring, also include end cap, wherein said end cap is coupled to outside described flange outer ring, by the inside of described hub bearing and external isolation.
Further, wherein said end cap interference is coupled on described flange outer ring.
Further, seal ring is provided with between wherein said end cap and described flange outer ring.
Further, wherein said seal ring comprises O type circle.
Relative to prior art, the beneficial effects of the utility model are as follows.
The utility model adopts end bracket enclosed, replaces bearing inner seal of the prior art, makes it have better bearing seal, can reduce intrusion and the corrosion of foreign matter, make bearing have longer working life.
And owing to eliminating traditional inner seal structure, what make bearing drags reduction, adds the fuel economy of vehicle.

Embodiment
Below with reference to drawings and Examples, the technological scheme of a kind of hub bearing that the utility model relates to is described in further detail.
Refer to shown in Fig. 1,2, the mode of execution that the utility model relates to provides a kind of hub bearing, and it comprises boss bolt 1, flange inner ring 2, outer side seal 3, steel ball 4, little inner ring 5, metal end 6, magnetic circle 7, retainer 8 and flange outer ring 9.
Wherein metal end 6 is installed on flange outer ring 9, by Bearing inner and external isolation, in order to substitute bearing inner seal structure of the prior art.
In one embodiment, metal end 6 and flange outer ring 9, both adopt the mode of interference fit to link together.And, in order to strengthen the steadiness coordinated between the two, O type circle (not shown) also can be set and embed wherein.
Compared with the double sealing structure of traditional bearing, the utility model adopts to be withheld on flange outer ring by metal end, by inside bearing and external isolation in an interference fit, the intrusion of foreign can be reduced, protection magnetic circle, reduces corrosion, increases the working life of bearing; , original inner seal can be saved again meanwhile, thus reduce bearing and drag, add fuel economy.
Technical scope of the present utility model is not only confined to the content in above-mentioned explanation, those skilled in the art can under the prerequisite not departing from the utility model technological thought, various deformation and amendment are carried out to above-described embodiment, and these distortion and amendment all should be worked as and belonged in scope of the present utility model.
Claims (4)
