Hold inner ring roller assembly 6-1 and wheel hub outer shaft bearing outer-ring 6-2 compositions.
As shown in accompanying drawing 1 and accompanying drawing 3, the change oil Method of Adjustment of hub assembly of commercial vehicle commander is：Tire bolt 1 is pacified in advance
It is attached in the tire bolt mounting hole 4-1 on wheel hub 4, the high-performance that high-performance abrasion-proof wheel hub inner oil seal 2 is pressed on wheel hub 4 is resistance to
In emery wheel hub inner oil seal press mounting hole 4-2, hub inner bearing outer ring 3-2 is pressed into the hub inner bearing outer ring press mounting hole on wheel hub 4
In 4-3, wheel hub outer shaft bearing outer-ring 6-2 is pressed into the wheel hub outer shaft bearing outer-ring press mounting hole 4-4 on wheel hub 4；In axle shell shaft-head 13
Moderate lubrication fat or lubricating oil are precoated at upper and bearing inner race roller assembly mating surface；With certain pressure by hub inner bearing
Circle roller assembly 3-1 is pressed into the position that axle shell shaft-head 13 is engaged, and ensures that hub inner bearing inner ring roller assembly 3-1 is pressed
It is attached to position；The wheel hub 4 for being pressed tire bolt, bearing outer ring and high-performance abrasion-proof wheel hub inner oil seal in advance is installed to axle housing axle
On first 13；Waveform spacer 5, wheel hub outer bearing inner ring roller assembly 6-1, axis head nut 7 are sequentially loaded on axle shell shaft-head 13；With
Defined moment of torsion continuously tightens axis head nut 7, makes wheel hub outer bearing inner ring roller assembly 6-1, hub inner bearing inner ring roller
Waveform spacer 5 between assembly 3-1 produces irreversible plastic deformation；While axis head nut 7 are tightened, the rotation of wheel hub 4 is measured
Turn pulling force, when the rotation pulling force of wheel hub 4 reaches setting (i.e. hub bearing pre-tightening force reaches setting), spindle nose is tightened in stopping
Nut 7, so that axis head nut 7, wheel hub outer bearing inner ring roller assembly 6-1, waveform spacer 5, hub inner bearing inner ring roller
It is overall that assembly 3-1 forms a rigidity；Axis head nut locking plate 8 is installed, and ensures locking plate and axle housing on axis head nut locking plate 8
Keyway on spindle nose 13 is engaged, and ensures the assembling bolt hole on axis head nut locking plate 8 and the combination on axis head nut 7 simultaneously
Bolt hole aligns, if the assembling bolt hole on axis head nut locking plate 8 is not alignd with the assembling bolt hole on axis head nut 7,
Continue to tighten axis head nut 7 with what defined moment of torsion can not retract, until the assembling bolt hole on axis head nut 7 and spindle nose spiral shell
Untill assembling bolt hole alignment on female locking plate 8；Assembling bolt 9 is installed, installs high-performance abrasion-proof wheel hub outer oil seal 10；
Lubricating grease is filled up in hub inner lumen between wheel hub outer bearing assembly 6 and hub inner bearing assembly 3 or fills lubricating oil；Wherein,
During axis head nut 7 is tightened, axis head nut 7 is tightened for that can not retract.
The change oil core of hub assembly Method of Adjustment of length i.e. of the present invention is special using the distinctive mechanics of waveform spacer
Property its is produced irreversible plastic deformation, so as to eliminate bearing, wheel hub etc. due to manufacturing, assembling the scale error brought, make wheel
Hub bearing pre-fastening reaches setting.
A kind of commercial vehicle commander of the present invention changes oil hub assembly and Method of Adjustment exempts to tie up with what is used on existing market
Non-maintaining wheel hub structure and adjustment mentioned in shield hub assembly (as health steps wheel end assembly, FAG bearing units), same type patent
Method has the difference of essence.The structure that the health used on existing market steps the wheel non-maintaining hub assembly in end is in hub inner bearing
Enclose and a high accuracy rigid spacer is installed between roller assembly and wheel hub outer bearing inner ring roller assembly, using strict control size
Chain size tolerance, the rigid spacer of high accuracy coordinate the method preselected to ensure the size of wheel end bearing pretightning force, i.e. adjustment wheel end
The essence of bearing pre-fastening is by strictly controlling dimension chain dimensional tolerance, the rigid spacer of high accuracy is produced very small bullet
Property deformation obtain required wheel end bearing pretightning force；The non-maintaining bearing units of FAG are similar with health wheel end Method of Adjustment advanced in years, make
The hub bearing inner ring withstood on together produces very small elastic deformation, so as to obtain required hub bearing pre-tightening force.With
Upper described health steps the structure at wheel end and FAG bearing units, Method of Adjustment is all by strictly controlling dimension chain dimensional tolerance, making
The rigid spacer (bearing inner race) of high accuracy produces very small elastic deformation to obtain required wheel end bearing pretightning force,
Such a method has the shortcomings that processing to part, assembly precision requirement is high, processing cost is expensive, assembly price is high.And institute of the present invention
A kind of commercial vehicle commander stated change oil hub assembly and Method of Adjustment be on the basis of existing common hub assembly, using waveform every
Covering distinctive mechanical characteristic makes it produce irreversible plastic deformation, so as to eliminate bearing, wheel hub etc. due to manufacturing, assembling what is brought
Scale error, hub bearing pre-tightening force is set to reach setting.
Can be by existing common hub assembly by a kind of above-described commercial car wheel hub assembly structure and Method of Adjustment
Maintenance mileage interval by (8000~12000) kilometer lifting arrive (150000~200000) kilometer, and cost far it is low
In the non-maintaining hub assembly that in the market generally uses, so as to reach between maintenance is improved on the premise of meeting performance
Every mileage, the purpose that easy to maintenance, maintenance cost is low, cheap.
It is described above, only it is highly preferred embodiment of the present invention, any restrictions is not done to the present invention, it is every according to the present invention
Technical spirit still falls within the technology of the present invention to any modification made for any of the above embodiments, change and equivalent structure change
The protection domain of scheme.
