The ideal ONE, is on the hot list again.
The cause is that an internet celebrity blogger named Wang Chengfo posted a video of Lantu Free and Ideal ONE challenging an unhardened mountain village road at the same time.
In this video, Landu Free successfully reached the top after several adjustments.
The ideal ONE directly damaged the main reducer of the rear axle, and the iron block splashed out of the main reducer, and even cracked the shell of the main reducer of the rear axle.
This situation is what we commonly call sweeping teeth.
Of course, this video has now disappeared, replaced by the ideal official test team, with two ideal ONE to re-challenge the Buddha Slope video, and a follow-up video of how to rescue the ideal ONE of the teeth.
During the blogger's experience, I don't want to guess, leave some space for everyone to discuss.
Why is the tooth sweeping
I'm still going to talk about it from a technical point of view.
First of all, why do you sweep your teeth?
The kind of thing of sweeping teeth is a very common sudden failure in the circle of playing off-road, and this failure mostly occurs on off-road whites who have been heavily modified by tires.
In order to look good, the wheels with large negative values are even flanges, the tire diameter and width are increased, and the axle is kept unchanged from the original car.
In some difficult off-road sections, the driver one foot on the throttle down, a long time high speed and large torque output, the axle of the original car is easy to be because the torque on the wheel is too large, the speed difference of the main reducer on the rear axle is too large and directly scrapped, and at the same time, there will be parts such as the transmission shaft, half shaft and so on.
The ideal ONE swept the teeth on the rear axle when challenging the Buddha Slope, and the basic reason was the same as the off-road vehicle sweeping teeth. One side of the wheel is idle at high speed, the speed difference of the main reducer is too large, and the gear damage is caused by exceeding the design load.
Of course, because of the output characteristics of the motor's constant power and constant torque, it indirectly realizes the effect of pulling high speed interference of the fuel vehicle, the output torque is large, and the friction resistance of the wheel on the side of the grip is large.
If you think about it, the output torque of the ideal ONE motor of 520 Nm is not added to the little linearity like a fuel car.
One foot electric door down, full output. Switch to the brakes, and can't stand it!
Therefore, what the ideal official notice says is indeed no problem, ESP is closed, the limit slip is canceled, and the differential speed is too large to cause damage.
But playing off-road vehicles should know such a truth, in the off-road time ESP is indeed to close, because ESP this thing in addition to limiting tire sliding, but also limit the power output, open, maybe this slope is even more unable to go up.
If you don't believe it, you can take a look at those classic off-road vehicles, which are not hung up on the low-speed four-wheel drive, ESP will actively shut down.
Therefore, the ideal announcement, you are right, you are not right, you are really wrong.
Ideal ONE This electric vehicle is really heavy, a few hundred kilograms of battery hanging, 2.3 tons away of the curb weight, the center of gravity is slightly offset backwards, that drive axle can not be grasped is a very normal thing.
Misleading
This kind of road, short-axis, light, and good grip is the easiest to get on.
In good weather, you can open an Alto, believe it or not?
Then, let's take a look at the video of the success of this official challenge
It can be noted that the ideal ONE that successfully challenged the first time has been replaced with an all-terrain tire.
I have a word about this, changing the all-terrain tire to challenge this bad road condition is the way to really be responsible for yourself.
So you see, after changing to the all-terrain tire, while with a reasonable choice of routes, the ideal ONE can challenge success.
The second adjusted blue ideal ONE is still the original silent tire, but you see, with reasonable route choice and throttle control, it can also successfully reach the top.
Of course, there is a prerequisite here, that is, the weather of the day seems to be better, and the road surface is relatively dry. This also increases the grip of the tires.
Ideal to prove your product in this way, no problem.
In fact, during the off-road process, the driver's operation error caused by the vehicle damage, that is much more than the design flaws of the vehicle itself.
- Wranglers twist the half shaft into twists, abound.
The ideal ONE of teeth sweeping can be both a case and a universal problem.
But the question is, is it really necessary for the ideal to prove that it can challenge the slope of success? What does it have to pass on? Is it the first in the world of my products, and can it be high speed and off-road?
Isn't this misleading consumers?
In the end, the ideal ONE is a new energy SUV running in the city, canceling the gearbox, the engine directly drives the electric motor to power, bringing a linear and comfortable driving experience, which is the most successful place for this car.
You have to drive this car to the track, to go off-road, isn't that difficult for strongmen?
You look at this challenge of Becoming Buddha Slope, on the ideal ONE's suspension trip, how much better than an MPV?
That's it, you still want to cross-country?
The basic architecture is not a thing that can be cross-country, you must prove that I can, then this is not indirectly misleading consumers.
You said, if someone drives the ideal ONE into the desert and flips over from the blade beam and destroys people, who should be counted for this?
At that time, the ideal technician will be busy again!
