Netizens @full's fat private space went through the "fort wing tiger breaker gate"! Open and the whole front wheel flew out。
The wheel's flying
Ford wing tiger has been on the market for more than a year, and it is not too short for this to happen. To date, neither the wing wing wing wing wing owner nor the other netizens understand why the wing wing wing wing has broken the axis, and it remains unclear whether long-amford has solved the problem of breaking the axis (because there are still cases of break-axis after recall)。
Today, we will look to the bottom and show you the beginning and the causes of the axis. Did the distinction between the horns of the sheep that had been mentioned earlier by netizens about the fact that the wing tigers abroad had never broken their axes? And to that end, we've got the horns of the united states, and we've been doing a comparison with the horns of the country。
The first thing to say is that wing tiger broke off the axis, not the real axis, but a component called the horn of the sheep, whose real name is turned around, because it is usually hidden in chassis and complex structures, so many do not know what's going on, and here, let's get this straight。
Where the hell is wing tiger
From the above figure, the yellow component (the horn of the sheep) is of considerable importance, as it is used to “assemble” the suspension of the tremors, the turning of the ball, the tire brakes and the lower arm, without which the parts cannot be linked。
Ok, that's where the problem is now. The horns of the sheep are fractured where they connect their arms, which directly leads to the following figure:
All right, let's take a look at the physical picture of the specific fractured position:
All the axes are broken here: 3d is as follows:
So why is this position so easy to break? Read the chart again:
The red part is the location of the main fracture, and if you don't understand it from the above, then a physical picture:
Why
As we have just said, structurally, the fractured position is more resilient and the metal is thin, and we can imagine that if the metal is not strong enough, it can easily break。
But what is this strength? Nobody knows. There are no industry standards. Only corporate standards, but business standards are generally not publicly available, and at least many domestic car manufacturers are not free to publish their own business standards. We also tried to contact ford in the united states, hoping to get that strength criterion, but it didn't。
Progress thus far seems to be encountering insurmountable obstacles, which in most countries cannot be resolved by the “gods” and “technologicals”. What do we do? Since we could not find the strength criterion, we went straight through the barrier with the horns of the united states。
No one in the country knows why the winged tigers are broken, including the owner himself, perhaps long-term amford himself, but because the cracker was taken away by the manufacturer, it may become a permanent mystery. The calf wonders, since the domestic winged tigers are exactly the same as the united states “original” winged tigers, is it possible to see some problems when it comes to buying the horns of an american winged tiger? There's never been an axis break in america
Of course, better to check if there is a problem with an axle-breaker horns, which we have contacted many of the owners of the “crashes” that, according to them, have been taken away by the 4s, “to” manufacturers. 4s stated that their vehicles would not be repaired free of charge if the broken horns were not returned。
The domestic sheep horns that appear in this video are indeed the original factory, but the horns that were re-produced after the long anfort announcement, i. E. The early first ones were not available。
But it doesn't matter, because there's still a break in the axis after the recall, so we're experimenting with the so-called “second batch”。
The approximate process for the purchase of sheep horns in the united states is to order individual spare parts on the united states official ford web site (a domestic car manufacturer does not have this service, and 4s store does not allow users to purchase individual spare parts, which can only be replaced and repaired in 4s), and then to go to the designated 4s spare parts store to collect the goods, or, of course, to order delivery。
For the sake of simplicity, the horns bought in the united states are called croissants 1 and the horns bought in the country are called croissants 2
There is little difference in structure:
First of all, these two horns are identical in structure, and the fact that essentially all of the horns with which mcpherson hangs are the same bird, that the weight of the front of the car is strictly the same, and that the critical stress points are concentrated on this small original, which is not particularly reliable, that it is an outmoded design, and that, in fact, mcporsson is 70 or 80 years old in its own right. You can say that porsche 911 is still using mcpherson, but that still does not change the fact that it is very backward, with most of the high-end cars having become semi-independent. Of course, mcpherson was technically backward, but after so many years, it proved to be “hard” and a “very good” hanger。
The appearance of crest 1 and crest 2 is slightly different, the grey is the imported and the painted black is the national product。
There's a slight difference in weight:
Although the appearance and structure are the same, apart from the colours, there are differences in the weight of the two horns。
Angle 1 is: 6. 120 kg
Angle 2 is: 6. 315 kg
Here we begin with the assumption that, regardless of the strength of the horns (the same assumption), what is the advantage in weight alone
We know that sheep horns are part of a half-axis, and wheeled, tires, half-axis, fork arms, tremors, springs are all under the spring
While vehicles are travelling on the road, the suspension system continues to accept shocks from the road, the best comfort of the crew inside the vehicle, and the car remains static relative to the road (the wheel alone fluctuates with the road), although it is almost impossible to do so through mechanical structures, but vehicles can be brought closer to this mode of movement by increasing the ratio of spring to spring quality。
The smaller the quality of the spring, the more flexible the vehicle is theoretically and the more comfortable it is to travel。
For example, you let an athlete carry a 5-pound backpack, he can still run fast and easy, but if he wears a 2-pound shoe, he may not run as fast as you。
The import of sheep horns is therefore, in terms of quality alone, better than that of domestic sheep horns (195g light)。
Size of the horn fracture:
As chart
The openings of crest 2 are slightly larger and the thickness of the metal is greater at 9. 49 mm。
On the other hand, the crest 1 is small and is only 8. 96 mm thick。
Note: the unit is mm, the difference is not obvious
Perhaps the metal thickness of the two horns is one of the reasons for the difference in weight. The anti-metallic pressure, although logically associated with the material, is certainly related to the thickness of the metal itself and is positive, i. E. The thicker, the more difficult it is to break. That's a good idea. How much easier can a thin wire and a thick wire be bent
So what about the fact that larger and deeper chinese horns can bear more power? We did a pressure experiment to simulate, to some extent, vehicle horn stress and to increase it:
The domestic horn broke when the instrument pressure reached 1696, while the american horn reached 24310; almost 50% higher
N. B. In fact, the crumbling of the horns may be related to a number of factors, not to the fact that the only cause of the break-up was the enormous power of the two positions, and that, in the experiment, we did not simulate the driving environment of the wing tigers, but simply gave them the same horns, both domestic and foreign, to different forces in the same position, to see which was more durable. Because structurally, the harder it gets, the harder it gets。
And, of course, the experiment was not entirely rigorous, but it was a reference, but it showed a lot. It can be said that the horns themselves are strong enough to face normal driving and need not be as strong as the horns, but the fact is, the horns of the country are broken
