Description
Technical field
The utility model relates to auto parts technology fields, and in particular to a kind of front-wheel wheel with high sealing performance
Hub axle is held.
Background technique
Hub bearing is one of key components and parts of automobile, its main function is load capacity and mentions for the rotation of wheel hub
For accurately guiding, radial load is still suffered from this requires it can not only bear axial load.
Chinese utility model patent if notification number is CN207064575U disclosed one kind gently on 03 02nd, 2018
Helical speed reduction gear structure, including shell are carried, the input shaft and output shaft of parallel arrangement, the input are equipped in the shell
Axis is equipped with first gear and input gear, and the output shaft, which is equipped with, forms the second of deceleration transmission cooperation with first gear
Gear, shell are equipped with the through-hole of positioning output shaft, and shell is equipped with the circular groove of positioning input shaft in the top of output shaft, sets in shell
There is the bracket positioned to input shaft one end and output shaft one end.
For the straight-line travelling for guaranteeing vehicle steadily, it should make deflecting roller that there is self-right effect, i.e., when deflecting roller is accidental
When encountering external force and deflecting, stone is such as encountered, can automatically return to the position of straight-line travelling immediately after external force disappearance.By
In front wheel camber, left and right wheels can be made often to act on contrary inclination thrust corresponding with camber angle, make tire wear
Increase；In order to avoid such case rolls thrust it is necessary to try every possible means to eliminate this, the method for elimination is made when installing wheel
The median plane of automobile two front wheels is not parallel, and two-wheeled leading edge distance is less than back edge distance, and the difference of the distance of the two is front-wheel
Toe-in, suitably selection toe-in angle, can make lateral force caused by toe-in cancel out each other with inclination thrust caused by camber, thus
Avoid the consumption of additional tire wear and power；But front-wheel hub bearing is also therefore caused to cause to accelerate to grind because of lateral force
Damage.
Utility model content
The utility model is that there are the deficiencies of accelerated wear test in order to solve existing front-wheel hub bearing, and providing one kind can subtract
The abrasion of small front-wheel hub bearing, and then the service life of bearing is improved, and structure is simple, it is easy to use that there is high leakproofness
The front-wheel hub bearing of energy.
The above technical problem is solved through the following technical scheme:
A kind of front-wheel hub bearing with high sealing performance, including bearing and sealing element further include balance base, magnetic circle
And dustproof cover；The left and right ends of bearing are fixedly attached a sealing element, and balance base is fixedly connected on the right end of bearing, magnetism circle
It is fixedly attached to the right end of balance base, dustproof cover is fixedly attached between bearing and balance base.
Due to the presence of toe-in of front wheel, it is equipped with front-wheel camber when designing front-wheel, that is, is mounted on front-wheel hub
Bearing also have and have certain angle with vertical direction accordingly, the utility model is eliminated by setting balance base because angle produces
The harm of raw aggravation bearing wear.
Preferably, bearing includes outer ring, ball, inner ring and retainer；Ball rolling is socketed on retainer, retainer
It is fixed between outer ring and inner ring.Ball bearing is selected, frictional force is reduced, reduces abrasion.
Preferably, the balance base is threadably secured and is connected on bearing.Detachable balance base, more convenient for bearing
It changes, saves cost.
Preferably, balance base is equipped with baltimore groove A and baltimore groove B, magnetism circle is fixedly attached in baltimore groove A, dust-proof
Lid is socketed in baltimore groove B.Loss of weight baltimore groove mitigates own wt, reduces bearing load.
Preferably, dustproof cover is concave shape, and concave port is towards balance base.The concave shape design of dustproof cover is convenient for subtracting
Weight.
The utility model can reach following effect:
The utility model provides the front-wheel hub bearing with high sealing performance, can reduce the mill of front-wheel hub bearing
Damage, and then the service life of bearing is improved, and structure is simple, it is easy to use.
Detailed description of the invention
Fig. 1 is a kind of overall structure diagram of the utility model embodiment.
Fig. 2 is the structural schematic diagram of balance base in the utility model embodiment.
Fig. 3 is the partial structural diagram of the utility model embodiment middle (center) bearing.
In figure: bearing 1, sealing element 2, balance base 3, magnetism circle 4, dustproof cover 5, outer ring 11, ball 12, inner ring 13 are kept
Frame 14, baltimore groove A61, baltimore groove B62.
Specific embodiment
The utility model is described further with embodiment with reference to the accompanying drawing.
Embodiment, a kind of front-wheel hub bearing with high sealing performance are joined as shown in figure 1 to 3, including bearing 1 and sealing
Part 2 further includes balance base 3, magnetic circle 4 and dustproof cover 5；The left and right ends of bearing 1 are fixedly attached a sealing element 2, balance
Seat 3 is fixedly connected on the right end of bearing 1, and magnetism circle 4 is fixedly attached to the right end of balance base 3, and dustproof cover 5 is fixedly attached to bearing
Between 1 and balance base 3.
Shown in Figure 2, bearing 1 includes outer ring 11, ball 12, inner ring 13 and retainer 14；The rolling of ball 12 is socketed in
On retainer 14, retainer 14 is fixed between outer ring 11 and inner ring 13.
Shown in Figure 3, balance base 3, which is threadably secured, to be connected on bearing 1.Balance base 3 be equipped with baltimore groove A61 and
Baltimore groove B62, magnetism circle 4 are fixedly attached in baltimore groove A61, and dustproof cover 5 is socketed in baltimore groove B62.Dustproof cover 5 is character cut in bas-relief
Shape, and concave port is towards balance base 3.
After vehicle front installation, the upper end is inclined outwardly, and then the Plane of rotation of front-wheel and longitudinally perpendicular plane form one
A angle, referred to as front-wheel camber, effect are to make to turn to light, make wheel against hub inner bearing, to reduce wheel hub
Load is conducive to drive safely, and general front-wheel camber is 1 ° or so；It is also therefore front-wheel bearing 1 and vertical plane is at 1 ° of left side
Right angle will lead to connecing for bearing 1 lower-left end contact with wheel hub lower end friction aggravation and 1 upper right side of bearing and wheel hub upper end
Wiping aggravation is touched, 1 service life of bearing is caused to greatly shorten, the utility model adds a balance base 3 in the right end of bearing 1, with flat
The frictional force that the gravitational equilibrium bearing 1 of weighing apparatus seat 3 increases by inclination angle, while such as magnetic circle 4 of some additional components or dustproof cover 5
Also it may be mounted on balance base 3, reduce by 1 load of bearing, increase 1 service life of bearing.
The utility model provides the front-wheel hub bearing with high sealing performance, can reduce the mill of front-wheel hub bearing
Damage, and then the service life of bearing is improved, moreover, additionally it is possible to reinforce the rigidity of bearing, and structure is simple, it is easy to use,
High reliablity.
The embodiments of the present invention have been described above with reference to the accompanying drawings, and however, the implementation is not limited to the above embodiments, this
Field those of ordinary skill can various changes and modifications may be made within the scope of the appended claims.
