Abstract
The utility model relates to a kind of automobile hub bearing of profile seal structure.Of the present utility modelly comprise bearing outer ring, two bearing inner races, be arranged on retainer and rolling element between bearing outer ring and two bearing inner races, between bearing outer ring and the two ends of two bearing inner races, be also provided with seal ring assembly, it is characterized in that the end face of end face higher than bearing outer ring of described bearing inner race, and described seal ring assembly is not higher than bearing outer ring end face.The utility model project organization is compact, takes into full account operating mode and the installation factor of automobile hub bearing in design, and sealing is strong, effectively can improve functional reliability and the working life of bearing, improves driving safety and the usability of automobile.
Description
(1) technical field
The utility model relates to the improvement of a kind of automobile hub bearing and unit thereof, belongs to the critical component of automotive transmission.
(2) background technique
Automobile hub bearing and unit thereof, Main Function is for automobile provides supporting, and provides accurate guiding for the rotation of automotive hub (wheel).
Automobile hub bearing, because vehicle is different, load is different, the design of bearing is distinguished to some extent.But in the design of bearing itself, it is less that the infringement caused bearing for preventing follow-up installation is considered.Analyze from the failure mode of bearing, because bad caused by bearing Rig up error accounts for larger ratio.Particularly for bearing seal assembly higher than bearing outer ring plane time, easily destroy black box press-fiting in process, make seal failure, cause bearing early failue.Or seal ring and miscellaneous part produce and interfere, produce abnormal sound.
(3) model utility content
Main purpose of the present utility model is the defect existed for existing automobile hub bearing design, and provide a kind of automobile hub bearing of profile seal structure, project organization is reasonable, can effectively improve automobile running reliability and long service life.
For this reason, the utility model takes following technological scheme: a kind of automobile hub bearing of profile seal structure, comprise bearing outer ring, two bearing inner races, be arranged on retainer and rolling element between bearing outer ring and two bearing inner races, between bearing outer ring and the two ends of two bearing inner races, be also provided with seal ring assembly, it is characterized in that the end face of end face higher than bearing outer ring of described bearing inner race, and described seal ring assembly is not higher than bearing outer ring end face.
Further, described seal ring assembly comprises seal ring and dust cover, described seal ring comprises four all has with described dust cover surface the lip contacted, seal ring comprises radial lip, low level secondary lip, high-level auxiliary lip and overhead kick lip, described radial lip effectively contacts with the external diameter of dust cover, high-level auxiliary lip effectively contacts with the inwall of dust cover with the secondary lip of low level, and overhead kick lip effectively contacts with dust cover medial plane, and seal ring and dust cover form multi-stage sealed cavity.
Further, described dust cover is in falling " 7 " font.
Further, scribble moderate lubrication fat in described each Seal cage, seal ring and dust cover are oppositely installed.
Further, around the skeleton of described seal ring, entirety is surrounded by rubber.
The utility model project organization is compact, takes into full account operating mode and the installation factor of automobile hub bearing in design, and sealing is strong, effectively can improve functional reliability and the working life of bearing, improves driving safety and the usability of automobile.
(4) accompanying drawing explanation
Accompanying drawing 1 is the utility model automobile hub bearing overall structure sectional view.
Accompanying drawing 2 is seal ring assembly structural representations of the present utility model.
1-bearing outer ring, 2-bearing inner race, 3-retainer, 4-rolling element, the inwall 6c-dust cover medial plane of the external diameter 6b-dust cover of 5-seal ring assembly 6-dust cover 5a-radial lip 5b-low level secondary lip 5c-high-level auxiliary lip 5d-overhead kick lip 6a-dust cover.
(5) embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1, a kind of automobile hub bearing of profile seal structure, comprises bearing outer ring 1, bearing inner race 2, is arranged on retainer 3 between bearing outer ring 1 and bearing inner race 2 and rolling element 4, seal ring and dust cover 6 forms seal ring assembly 5.Seal ring assembly is not higher than bearing outer ring end face.
With reference to Fig. 2, seal ring has four lips, surface each with dust cover all contacts respectively, the radial lip 5a of seal ring effectively contacts with the external diameter 6a of dust cover, the secondary lip 5b of low level effectively contacts with the inwall 6b of dust cover with high-level auxiliary lip 5c, and seal ring overhead kick lip 5d effectively contacts with dust cover medial plane 6c.The profile seal assembly of " multiple spot fits tightly " that dust cover 6 and seal ring are formed and multistage A, B, C seal chamber.Moderate lubrication fat is scribbled in each Seal cage.And oppositely install.
The dirts such as outside water, silt can be stoped to enter Bearing inner and stop lubricating grease to external leakage.And outwards to be leaked successively difficult to entering or oppositely flowing out by Seal cage A, B, C.
And entirety is surrounded by rubber around the skeleton of seal ring, effectively can resist the corrosion of outside dirt, keep the validity of sealing.
