Description
Technical field
The present invention is on a kind of heavy-load type front axle hub.
Background technology
Propons is the important component of cargo vehicle, and the size of its bearing capacity decides the cargo capacity of automobile.Particularly
Heavy-load type automobile, the bearing capacity of propons seem even more important.The main load bearing component of propons has wheel hub, knuckle, I-beam
Deng, these parts will not only bear the load of vertical direction, still suffer from brake when load transfer, torsional moment and road surface
Impact, force-bearing situation is considerably complicated.These load bearing components will have larger safety coefficient to maintain rational service life.
In the prior art, hub inner bearing mounting hole wall thickness is relatively thin, and rigidity is small, it is impossible to bears larger shock loading, takes turns
Gap is produced between hub interior axle bearing outer-ring and wheel hub, causes hub inner bearing hole inner wall abrasion, hub bearing loosens；It is limited to
The limitation of ABS gear rings and back-plate, it is impossible to strengthen wheel hub by reducing the drop of step surface；Due to the limitation of wheel hub, wheel
Hub bearing specification (mainly inside and outside footpath) is limited to certain scope, can not increase, cause bearing life to reduce.
The content of the invention
Present invention aim to address the problem of hub rigidity difference, increase the bearing capacity at hub inner bearing hole, improve
Take turns the bearing capacity and service life of whole front axle assy.
To realize above-mentioned technical purpose, the present invention provides a kind of heavy-load type front axle hub, and it includes：Wheel hub end face and wheel hub
Mounting shaft hole, the inside warp beam of the wheel hub mounting shaft hole, which is held, is rotatably connected to knuckle, wherein：In the wheel hub mounting shaft hole
End outer wall only there is the step surface being connected with gear ring, the end face of the end face of the gear ring and the knuckle it
Between it is directly relative；The knuckle has：Integrate the brake of installation connection, and the camshaft branch of end face disposed thereon
Frame, the camshaft stand, which is axially fixed, is provided with camshaft；And the cam portion of the camshaft and the brake are equal
Between the wheel hub end face and the end face of the knuckle.
As a further improvement, the knuckle also has：Brake-shoe mounting hole positioned at its lower surface, brake-shoe with
Brake-shoe installation bolt in the brake-shoe mounting hole is fixedly connected.
As a further improvement, the bearing is the inclined cone bearing in wheel hub end face described in phase.
As a further improvement, there is axial arranged mounting surface, the mounting surface on the upper surface of the knuckle
It is upper that there is camshaft stand mounting hole.
As a further improvement, the knuckle, which also has, is located at middle part and axially disposed ABS probe mounting holes.
The present invention cancels independent back-plate, and integrated installation has the braking with back-plate function on knuckle
Device, eliminate technology puzzlement of the prior art so that space is freer, and wheel hub is integrally strengthened, increase hub inner bearing peace
The wall thickness at hole is filled, increases its rigidity.

Embodiment
As shown in Fig. 1 to 5, the present invention provides a kind of heavy-load type front axle hub 1, and it includes：Wheel hub end face 2 and wheel hub installation
Axis hole 3, the inside of the wheel hub mounting shaft hole 3 are rotatably connected to knuckle 4 through bearing 13, wherein：In the wheel hub installation axle
The end outer wall in hole 3 only has the step surface 6 being connected with gear ring 5, the end face of the gear ring 5 and the knuckle 4
End face between it is directly relative；The knuckle 4 has：Integrate the brake 7 of installation connection, and end face disposed thereon
Camshaft stand 8, the camshaft stand 8, which is axially fixed, is provided with camshaft 9；And the cam portion of the camshaft 9 and
The brake 7 is respectively positioned between the wheel hub end face 2 and the end face of the knuckle 4.
As a further improvement, the knuckle 4 also has：Brake-shoe mounting hole 10 positioned at its lower surface, braking
Hoof 11 is fixedly connected with the brake-shoe installation bolt 12 in the brake-shoe mounting hole 10.
As a further improvement, the bearing 13 is 2 inclined cone bearing of wheel hub end face described in phase.
As a further improvement, there is axial arranged mounting surface 14, the installation on the upper surface of the knuckle 4
There is the mounting hole 15 of camshaft stand 8 on face 14.
As a further improvement, the knuckle 4, which also has, is located at middle part and axially disposed ABS probe mounting holes
16。
The present invention cancels back-plate, and integrated installation has the brake with back-plate function on knuckle, excludes
Technology puzzlement of the prior art so that space is freer, and wheel hub is integrally strengthened, and increases at hub inner bearing mounting hole
Wall thickness, increase its rigidity.Solve the problems, such as hub rigidity difference, increase the bearing capacity at hub inner bearing hole；Optimize front axle wheel
End structure, related components are integrated；Improve the service life of wheel hub and hub bearing；Improve and take turns whole front axle assy
Bearing capacity and service life.
The present invention cancels back-plate, and the function of back-plate is integrated on knuckle, increases brake-shoe on knuckle
Mounting hole, ABS mounting holes, camshaft are arranged on knuckle upper surface by camshaft stand.So that wheel hub is integrally strengthened, increase
Wall thickness at hub inner bearing mounting hole, increase its rigidity.
Limited in the setting to step surface 6 without the concern for the hole of back-plate, only reserved gear ring mounting surface, and axle at this
Bearing bore is radially enlarged, compared to before, bearing hole is bigger, hole wall is thicker.
Wheel hub of the present invention is integrally strengthened, and increases the wall thickness at hub inner bearing mounting hole, increases its rigidity, the improvement project
The fault rate that hub inner bearing loosens, worn can be effectively reduced, extends the service life of wheel hub；Increase the hole of interior axle bearing bore
Footpath, improve bearing life；The use of back-plate is eliminated, the function of back-plate is integrated with knuckle, takes turns end structure
It is compacter；Increase the bearing capacity and reliability of front axle assy.
It should be appreciated that invention which is intended to be protected is not limited to non-limiting embodiments, it should be understood that non-limiting embodiment party
Case illustrates as just example.The desired substantive protection domain of the application is more embodied in independent claims offer
Scope, and its dependent claims.
