7th structure has very specific description in Chinese patent literature CN108773752A, and details are not described herein.7th
In structure, toroidal cavity can be constructed on the joint surface of matrix wheel rim and support wheel rim, and every edge forming goes out half of toroidal cavity.
Above seven kinds of structures cover the basic structure of most of wheel hub, but do not cover it is complete, it is big from principle
Enable enough covers all wheel hubs, is based on same principle, and those skilled in the art is able to determine how out toroidal cavity 2,
It no longer lists one by one herein.
In the radial direction of wheel hub, the centrifugation side that ball adapts to cross section is the toroidal cavity 2 of arc, and advantageous cross sections are circle
The toroidal cavity 2 of shape.
Further, the diameter of ball is less than the length in wheel hub radial direction of 2 cross section of toroidal cavity.
When balance element 10 is using ball, the diameter of ball is 2 cross section of toroidal cavity at two points of wheel hub radical length
One of ~ 4/5ths, to ensure smoothness that ball is run in toroidal cavity 2.
Further, the number of ball is 8 ~ 20.When quantity is on the low side, the dispersibility of ball is relatively weak, rolls in principle
Pearl quantity is more to advantageously form the relatively good situation of redistribution of mass, but more ball overall cost is also higher.
When ball individual is smaller, may be considered particulate matter in a way, only ball under conditions of rationality,
Even dosage is more, it should also be the roughly the same ball set of partial size.Further, in some embodiments, using
Grain object substitutes ball, and compared to ball, particulate matter may be considered the solia particle of granularity in a certain range, does not have opposite
Stringent single partial size.
Particulate matter has certain fluid properties, therefore under the action of the centrifugal force, dispersibility is relatively more preferably.
Particulate matter is based on mobility, and what may further be replaced is liquid, particulate matter or liquid filling out in annular housing 2
Charge is 1/5th ~ half of annular space volume.Limited by manufacturing process, when loading require be higher than two/
Often compare for the moment and be difficult to reach, in some assembly technologies, can will such as main hub 5 and accessory whorl hub 3 immerse in liquid into
Row state, this mode will cause the significant wastage of liquid, especially liquid and be completely unnecessary full of toroidal cavity 2, and
It is lost the effect of quality rebalancing.
When the amount of amount of liquid or particulate matter is very few, the effect of Mass Distribution rebalancing embodies relatively not obvious enough,
Therefore, loading not preferably less than 1/5th of 2 capacity of toroidal cavity.
In some implementations, it is also necessary to consider the density of institute's filler particles object and liquid, particulate matter selectable range compares
Extensively, it and is easier to find particulate matter identical with hub material, it is assumed that hub body uses cast steel, then particulate matter can be adopted
Use steel sand.In contrast, fluid density is generally less than the density of cast member, even cast aluminium, and density is also the 2.7 of water density
Times.Therefore, in a preferred embodiment using particulate matter as filler.
In some embodiments, balance element 10 use arc body, the arc body centrifugation side surface and toroidal cavity 2 from
Heart side surface curvature is identical, and under the action of the centrifugal force, the centrifugation side surface of arc body and toroidal cavity 2, which coincide, slides, to annular
The damage on 2 surface of cavity is smaller.
Further, the arc length of arc body is more than or equal to 2 cross section of toroidal cavity at 1.5 times of wheel hub radical length, and
Less than or equal to 3 times of the length, arc body will not generate rolling in toroidal cavity 2, or generate clamping stagnation, and monomer is relatively
Less, be conducive to dynamically balanced realization.
Further, if there is the ball or arc body in toroidal cavity 2, lubricating oil is preset in toroidal cavity
Or lubricating grease, or it is furnished with oil filler point for toroidal cavity, to reduce the coefficient of friction of balance element 10 Yu toroidal cavity 2.
