Description
Technical field
The present invention relates to automobile mechanical field, in particular to a kind of automotive hub roundness device for fast detecting.
Background technique
The hub bearing of car goes over most to be to use single-row tapered roller or ball bearing in pairs.With the hair of technology
Exhibition, car widely use car hub unit.The use scope and usage amount of hub-bearing unit are growing,
Developed to the third generation: the first generation is made of double row angular contact bearing.The second generation has one to be used for bearing in outer rollaway nest
Bearing can simply be set on wheel shaft and be secured with nuts by fixed flange.So that the maintenance of automobile becomes easy.Third generation wheel
Hub bearing unit is matched using bearing unit and anti-brake holding system.Hub unit has been designed to inner flange and outward flange,
Inner flange is fixed by bolts in drive shaft, and entire bearing is installed together by outward flange.After automobile tire is full of gas, outside tire
Along that can fit closely with hub flange, prevent the gas in tire from leaking.If hub flange just will affect by collision deformation
The adaptation of itself and tire outer, causes tire secretly to leak.So car owner is commonly use vehicle during day, it should be noted that avoid collision
Wheel hub prevents wheel hub from deforming.If the flange appearance of automotive hub is severely deformed, we can with the naked eye be had found;If seen not
Out, illustrate to deform unobvious, need first to unload wheel, be sprinkled with water at the position that links of tire and wheel hub, generate the portion of bubble
Position just illustrates that the position is exactly the place for causing tire secretly to leak.If automotive hub deformation does not pay attention to maintenance, it will cause more tight
The damage of weight, makes burst hub.Burst hub will lead to true pneumatic tyre internal gas and leak from crack, become the hidden of tire fracture
Suffer from, when there is such case, has to the tire more renewed in time, because the danger coefficient of bulging of tyre is very high, threat is driven
The personal safety for the person of sailing, so centainly should not general idea.
Therefore it needs often to detect the roundness of wheel hub, if wheel hub has deformation, it will accelerate tire broken
It splits, to cause danger, and existing method is exactly to draw circle around wheel hub using big compasses, in this way when detection pair
It can be detected in deforming biggish wheel hub, but be not easy to detect for deforming small wheel hub, there are security risk, when
Can with the naked eye observe directly wheel hub deformation when, it is abnormally dangerous, due to the effect of power be it is mutual, if wheel hub
It is non-round, it is also different to the pressure of tire in the rotation, to will be destroyed to tire, also when detection, make
It is detected with infrared or ultrasonic instrument, but it is complicated for operation, it needs to be analyzed using multi-group data, operation is extremely not
Just, while when equipment damage also inconvenience repairs, and device also when in use, is detected to wheel hub roundness
When detected using mold, but it is inconvenient different size of wheel hub is detected, to need to replace back and forth different
Wheel hub is stepped up to detect by mold, wastes user's lead-time, and equipment inconvenience also detects roundness
When intuitively observed, bring inconvenience for operator.
