Description
Technical field
The invention belongs to technical field of automobile parts, specifically, relate to a kind of Novel light card automobile hub unit.
Background technology
In recent years, China's automobile industry is in the period of developing rapidly, and volume of production and marketing improves constantly, and considers from long term growth, respectively
Complete vehicle quality is had higher requirement by individual manufacturer and user.First have on the axletree of traditional vehicles wheel is installed
Hub, wheel hub end face is provided with multiple fixed screw or nut, is fixed on wheel hub by nut or screw by wheel hub spoke.Above-mentioned
The hub of structure, in order to realize the connection of hub and spokes wheel rim, needs to be fixed by multiple screws or nut,
In the current epoch being particular about work efficiency, it appears the most loaded down with trivial details, structure is the most complicated, cost is big, and gives a discount greatly in aesthetics
Button.Based on this, it is common that the hub of manufacture high-quality has become as each automobile hub bearing manufacturing and processing enterprise domestic
Make great efforts target.
The effect of the hub bearing rotation primarily as supporting part with for wheel hub provides and accurately guides, and it had both born radially
Load bears again axial load, is very important parts, is also the important component part of carload and rotation, its
There is the advantages such as good, lightweight, the compact conformation of assembling property, be early widely used in car, also have in truck by
Step expands the trend of application.Traditional bearing used for automobile wheels is by two set taper roll bearings or angular contact ball bearing combination
Become, the operation such as the adjustment of the pretension of bearing, sealing and play, all carry out on auto production line.This structure fills
Join difficulty, high cost, poor reliability, it is difficult to adapt to the competition in market.
Summary of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, it is provided that a kind of Novel light card automobile hub unit,
For solving Standard of the prior art difficulty, the problem of high cost, its Novel light card automobile hub unit provided
Convenient installation, dismounting, can reduce maintenance cost, can realize bearing clearance self-regulated, good airproof performance, and service life is long.
In order to realize above-mentioned goal of the invention, the technical solution adopted in the present invention is: a kind of Novel light card automotive hub
Unit, mainly includes that wheel hub, clutch shaft bearing and the second bearing, described clutch shaft bearing and the second bearing lay respectively at wheel hub two
End, all comprises a keeper and some rolling elements, wheel hub is also associated with some boss bolts in clutch shaft bearing and the second bearing.
Preferably, the right part, inside of above-mentioned wheel hub is disposed with combination sealing, O, single sealing, list from right to left
Sealing, combination sealing, described combination sealing and single sealing are respectively positioned between the Internal and external cycle of clutch shaft bearing and the second bearing, O
Between the second bearing inner race large end face and axle.
Preferably, the inner ring of above-mentioned clutch shaft bearing and the inner ring of the second bearing contact with each other.
Further, above-mentioned wheel hub is columnar structured.
Further, above-mentioned boss bolt be shaped as middle part band pad stud or for head T-bolt.
Further, above-mentioned boss bolt also includes mutually revolving friction tight nut with it.
Further, it is provided with nylon ring in above-mentioned nut.
Further, the kind of above-mentioned rolling element is ball or taper roller or cylindrical roller.
Compared with prior art, the invention have the advantages that:
1, the present invention is by double combination sealings, double single sealing and the use of O, it is ensured that the work of hub inner bearing
Make clean environment, non-maintaining purpose can be reached；
2, contact with each other between two inner rings of the present invention, in installation process, by the cooperation of two bearings, it is to avoid coordinate not
Situation about putting in place, it is ensured that use play normally, and achieve play self-regulated, and then improve the life-span of bearing；
3, using labyrinth type combination sealing outside the hub bearing of the present invention, inner side uses strengthened sealing, can guarantee that anti-
Dirt leakproof fat, and for crude oil lubrication system, it is possible to prevent the oil immersion of gear-box to enter Bearing inner, it is achieved efficient sealed effect
Really；
4, the medial and lateral hub bearing of the present invention uses nylon66 fiber keeper, the biggest shaking when improving bearing rotary
Dynamic noise, moreover it is possible to substantially reduce rotary inertia during bearing rotary, it is most important that, just in case because fault causes keeper beam to break
Splitting, chip breaking will not be mixed in bearing rotary raceway and aggravate bearing ablation damage, has higher safety coefficient to ensure；
5, the present invention utilizes bearing basal plane and shaft shoulder location, cancels original spacer ring structure, and simplification can assemble flow；
6, the simple in construction of the present invention, has the advantage being easily installed, replacing, and can improve installation effectiveness, has the biggest
Market popularization value.
It addition, in addition to objects, features and advantages described above, the present invention also have other purpose, feature and
Advantage.Below with reference to accompanying drawings, the present invention is further detailed explanation.
