Abstract
The present invention relates to a kind of new hub-bearing unit seal assembly, including be attached on skeleton rubber projections, stainless steel insert, lip one, lip two, lip three, lip four；Described rubber projections, lip one, lip two, lip three, lip four are the whole one-piece construction depended on skeleton；Described skeleton is arranged on wheel hub outer ring, and described stainless steel insert is arranged on wheelboss flange disk；Described lip one has gap between stainless steel insert in its natural state；The invention further reduces the probability that muddy water is flowed directly into；Increase a lip to improve sealing property during big load, will not also increase torque during side crops industry.
Description
Technical field
The present invention relates to automotive hub field, and in particular to a kind of new hub-bearing unit seal assembly.
Background technology
Because the hub bearing of automobile has very high requirement for durability and high-reliability, except avoiding automobile bearing
Occur beyond raceway fatigue failure, hub bearing seal fails are also relatively common failure mode, frequently can lead to the external world
The pollutant such as silt, dust and steam invade in bearing, bearing is produced abnormal sound, accelerate the abrasion of raceway groove and steel ball, make
There is fatigue flake in steel ball, channel surface, and internal grease is revealed laterally, cause insufficient lubrication, life of product are influenceed, if grease
Leak on brake disc or brake drum, its stopping power can be caused to decline and fail, consequence is very serious.
Existing hub-bearing unit typically uses the structure of Assembled sealer with seal assembly, and seal is used
3 lips are designed, and skeleton, into water-retaining structure, is had a disadvantage in that by bending row：
1st, the skeleton structure that existing scheme is used is fairly simple, and water still can be flowed into lip along gap, produce bearing
Raw abnormal sound, accelerates the abrasion of raceway groove and steel ball, steel ball, channel surface fatigue flake is occurred；
2nd, lip is contacted all the time, and torque is all consistent when lateral load is smaller and when lateral load is big, when lateral
When load is larger, sealing property is poor.
The content of the invention
Relatively simple for structure in order to solve hub bearing sealing element framework in the prior art, water still can be flowed into along gap
In lip, bearing is produced abnormal sound, accelerate the abrasion of raceway groove and steel ball, steel ball, channel surface fatigue flake is occurred；Lip begins
Terminating is touched, and torque is all consistent when lateral load is smaller and when lateral load is big, when side load is larger, sealing
Can many disadvantages such as poor, the invention provides a kind of hub-bearing unit seal assembly, described seal assembly include according to
It is attached to rubber projections on skeleton, stainless steel insert, lip one, lip two, lip three, lip four；
Described rubber projections, lip one, lip two, lip three, lip four are the whole one chip depended on skeleton
Structure；
Described skeleton is arranged on wheel hub outer ring, and described stainless steel insert is arranged on wheelboss flange disk；
Described lip one has gap between stainless steel insert in its natural state.
Preferably, described hub-bearing unit is partially protrude through stainless steel insert with the rubber projections in seal assembly and leaned on
On nearly rubber projections one end, described lip two, lip three, lip four are in contact with stainless steel insert in its natural state.
This invention design plays the outside muddy water of stop using the rubber bumps being attached on skeleton and flows directly into lip from upside
Mouthful effect, stainless steel insert plays stop muddy water and flowed into from right side, and whether lip is not contacted with skeleton load is small, so
Spin friction torque is smaller, will be contacted with skeleton when load is big, to improve sealing property；Remaining lip two, three, four is in addition
Three lips contact the sealing property for ensureing bearing in side crops industry all the time；The invention further reduces what muddy water was flowed directly into
Probability；Increase a lip to improve sealing property during big load, will not also increase torque during side crops industry.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, without having to pay creative labor, may be used also
To obtain other accompanying drawings according to these accompanying drawings.
Fig. 1 is hub bearing seal component architecture schematic diagram of the invention.
Label declaration：1st, skeleton；2nd, rubber projections；3rd, stainless steel insert；4th, lip one；5th, lip two；6th, lip three；7、
Lip four；8th, wheel hub outer ring；9th, wheelboss flange disk.
Embodiment
With reference to embodiment, the present invention is described in further detail, following examples be explanation of the invention and
The invention is not limited in following examples.
Embodiment：
As shown in Figure 1, the invention provides a kind of new hub-bearing unit seal assembly, including it is attached to bone
Rubber projections 2, stainless steel insert 3 on frame 1, lip 1, lip 25, lip 36, lip 47；Rubber projections, lip one,
Lip two, lip three, lip four are the whole one-piece construction depended on skeleton；Skeleton 1 is arranged on wheel hub outer ring 8, no
The steel skeleton 3 that becomes rusty is arranged on wheelboss flange disk 9；Lip 1 has gap between stainless steel insert 3 in its natural state；Rubber
Projection 2 is partially protrude through on the top of stainless steel insert 3, lip two, lip three, lip four in its natural state with stainless reinforcing bar
Frame is in contact, and this invention design plays the outside muddy water of stop using the rubber bumps being attached on skeleton and flows directly into lip from upside
Mouthful effect, stainless steel insert plays stop muddy water and flowed into from right side, and whether lip is not contacted with skeleton load is small, so
Spin friction torque is smaller, will be contacted with skeleton when load is big, to improve sealing property；Remaining lip two, three, four is in addition
Three lips contact the sealing property for ensureing bearing in side crops industry all the time；The invention further reduces what muddy water was flowed directly into
Probability；Increase a lip to improve sealing property during big load, will not also increase torque during side crops industry.
Furthermore, it is necessary to explanation, the specific embodiment described in this specification, is named the shape of its parts and components
Title etc. can be different.The equivalent or simple change that all construction, feature and principles according to described in inventional idea of the present invention are done, is wrapped
Include in the protection domain of patent of the present invention.Those skilled in the art can be to described specific implementation
Example is made various modifications or supplement or substituted using similar mode, structure without departing from the present invention or surmounts this
Scope as defined in the claims, all should belong to protection scope of the present invention.
