The mounting structure form of these two kinds of hub oil seals all exists defective and deficiency, for first kind of structure, needs hub oil seal seat ring of special processing, and assembling simultaneously need press-fit or hot charging, thereby manufacturing cost is high, complex process, and number of spare parts is many; For second kind of structure, because hub oil seal seat ring and bearing are made of one, cause bearing arrangement special, part universality is bad.
The utility model content
The utility model proposes a kind of front axle assembly and automobile, and the mounting structure of its hub oil seal can reduce processing parts and working position, and is simple in structure.
The technical scheme of the utility model is achieved in that
A kind of front axle assembly comprises steering swivel, also comprises:
Wheel hub is arranged on the said steering swivel through hub inner bearing and wheel hub outer bearing, and said wheel hub is provided with the cavity that is used to install grease, and said grease is used for lubricated said hub inner bearing and said wheel hub outer bearing;
The ABS gear ring is press fit into through interference fit on the outer ring of said wheel hub;
Hub oil seal, the outer ring of said hub oil seal are press fit on the inner ring of said ABS gear ring;
Wherein, said steering swivel is provided with the boss that is used for the said grease of said hub oil seal inner lip fitted seal.
Preferably, the installation diameter of said hub oil seal inner lip is greater than the overall diameter of the retainer of said hub inner bearing.
Preferably, the inner ring of said hub inner bearing is arranged on the said steering swivel through interference fit.
Preferably, the inner ring of said wheel hub outer bearing is arranged on the said steering swivel through interference fit.
A kind of automobile comprises foregoing front axle assembly.
Hub oil seal is installed between ABS gear ring and the steering swivel in the utility model technical scheme; Through boss on the steering swivel and hub oil seal inner lip fitted seal grease; Special hub oil seal seat ring need be set; The mounting structure of this hub oil seal can reduce processing parts and working position, and is simple in structure.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work property, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the cross-sectional view of a kind of front axle assembly of the utility model;
Fig. 2 is the perspective view of a kind of front axle assembly of the utility model.
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1 and Fig. 2, in first embodiment of a kind of front axle assembly of the utility model, said front axle assembly comprises steering swivel 5, wheel hub 1, ABS gear ring 2, hub oil seal 3.
Said wheel hub 1 is arranged on the said steering swivel 5 through hub inner bearing 4 and wheel hub outer bearing 6, is provided with the cavity 7 that is used to install grease in the said wheel hub 1, and said grease is used for lubricated said hub inner bearing 4 and said wheel hub outer bearing 6.
In a preferred embodiment of the utility model; The inner ring of said hub inner bearing 4 is arranged on the said steering swivel 5 through interference fit; The inner ring of said wheel hub outer bearing 6 is arranged on the said steering swivel 5 through interference fit; Said then wheel hub 1 is arranged on said hub inner bearing 4 and the said wheel hub outer bearing 6, and bearing inner ring and steering swivel 5 are designed to interference fit, can prevent that the grease in the cavity 7 from getting into wheel hub 1.
Said ABS gear ring 2 is press fit on the outer ring of said wheel hub 1 through interference fit.
The outer ring of said hub oil seal 3 is press fit on the inner ring of said ABS gear ring 2; The inside face of said ABS gear ring 2 is used to install the outer ring of said hub oil seal 3.
Said steering swivel 5 is provided with the boss 8 that is used for the said grease of said hub oil seal 3 inner lip fitted seal.The function of 8 hub oil seal seat rings of said boss, through said boss 8 is set on the steering swivel 5, the grease in said boss 8 and the said cavity 7 of said hub oil seal 3 inner lip fitted seal, thus do not need to be provided with again the hub oil seal seat ring.
Preferably, the installation diameter of said hub oil seal 3 inner lips is greater than the overall diameter of the retainer of said hub inner bearing 4.
The installation diameter of said hub oil seal 3 inner lips is greater than the largest outer diameter of the retainer or the roller of said hub inner bearing 4; Because the lip of hub oil seal 3 is higher than the retainer of hub inner bearing 4 or the external diameter of roller; So that when wheel hub 1 assembling and dismounting, can not damage said hub oil seal 3.
In addition, the invention also discloses a kind of automobile, said automobile is except comprising that each component part identical with automobile of the prior art is (like power system; Running gear etc.) outside; Also comprise described front axle assembly, because each embodiment part is described in detail the composition structure of said front axle assembly in front, for length is considered like preceding each embodiment; Repeat no more at this, get final product with reference to the description of front relevant portion.
