It doesn't matter if the engine is bad, we can increase the speed ratio, normal road cars, the rear axle speed ratio is about 4, we are big enough to increase to 6, or even 7, and I am afraid that the engine will not be able to bring up?

"I think it's more appropriate to enlarge the rear axle speed ratio to more than 6, so that it will save our clutch." Wang Erzhu continued.

Clutch?

The second problem that Mia wants to say is that since she pulls so much, it is estimated that the clutch cannot be used, and the hydraulic torque converter must be used.

The engine of the car is always rotating, but the wheels are not, so there needs to be a device in the middle that separates and combines power, which is the clutch, the ordinary clutch, all of which are friction plate type, and there is no problem with normal use, but pulling so many goods, maybe a start, will make the clutch plate friction catch fire and be reimbursed.

Everyone is an expert, and what they are talking about is the most critical issue, let's talk about the power system first, Mia is taking the high-end route, and Wang Erzhu is talking about the civilian route.

The problem that can be solved with a clutch is why use a torque converter? Add that thing, and the cost will have to increase by tens of thousands!

"If the clutch had been used, the life would have been greatly reduced." Mia said: "Our Mercedes-Benz heavy trucks need to have a certain lifespan, and if a clutch plate is scrapped in a month, it will damage the reputation of our Mercedes-Benz heavy trucks." ”

Of course, she still has to think about the reputation of Mercedes-Benz heavy trucks, and those things that damage the reputation must not be done.

Bulky cars? Which one is not a torque converter? More than two hundred engines, ordinary clutches, capable of large parts? This gets out? It's a joke in the industry.

"Absolutely." Wang Erzhu said: "Normal use? Two or three years is absolutely fine? If the customer himself does not know how to operate, such as starting on a ramp, then burns the clutch? They are to blame. ”

Remember the URL

Ramp start? Mia today? The things I heard were like a fantasy: "Can't our vehicles start on a ramp?" What if you stop on the ramp? ”

Wang Erzhu's face showed a very surprised look: "What else can I do?" Go back and get back on! ”

Those overloaded vehicles? Who will start halfway up? Just stop? So there's only one way? Rewind? Back on? It's impossible to start, and who doesn't know this point of overloading!

It's not just about burning the clutch, it's also about breaking the half shaft, and maybe breaking the back of the toothbag? Anything is possible.

Today? Mia's three views were seriously refreshed.

Once parked on the ramp? All right? Rewind and start over? Can I call a taxi?

"Clutch, just for starting." Wang Erzhu continued: "So? It can greatly extend the life of the clutch. ”

"Wait, what about changing gears?" Mia asked.

Driving school to learn to drive, all know that the left foot has to step on the clutch, so that you can change gears, not to mention these experts, now, Mia actually heard Wang Erzhu say that you don't need to step on the clutch to change gears, which is quite strange.

"The throttle gear is cooperative, this won't be, how can you be an old driver." Wang Erzhu continued.

Mia was even more stunned, she didn't expect that these heavy trucks came to the big country in the East, and they actually played tricks?

Open a heavy truck, only at the start, use the clutch once, as long as the start is successful, and then it has nothing to do with the left foot, shifting, completely is the speed, throttle and gear cooperation, only the most skilled master, can complete such an operation, if not skilled, the gearbox will be seriously beaten, there is a loud sound, and if you encounter this situation, it will be scolded.

Our old drivers in the big eastern countries, technology is a cow!

In this way, the problem of the power system is solved, just use the current power pack, no problem at all, as for the user, if it is broken, they will not use it! This reason is too far-fetched, right?

Mia already regretted it a little.

Mia barely suppressed her thoughts, and then said: "When the load is large, the pressure on the steering system will also increase, and more steering assistance is required. ”

"It's okay, our old driver's arms are very strong. The old liberation, who didn't have the help of the direction before, also swished, big deal, stand up and take the steering wheel. Wang Erzhu said.

Mia felt a chill in her heart again.

Is this to ruin the reputation of their Mercedes-Benz heavy trucks, they just promised it, is it right or wrong.

"I believe that in the future, our Mercedes-Benz heavy truck will become an important boost to the construction of the motherland." Qin Zhenhua said: "We have so much technical foreign aid, we must be able to do our road transport vehicles, oh no, large transport vehicles to the best." ”

Sure enough, this guy was calculated, at this time Mia's heart, suddenly sprung up with such a thought, and finally moved himself by the Australian road train, hoping to accumulate some experience, who would have thought, here and Australia, completely different, this is the lowest version, to Australia, who will be satisfied.

Mia was very helpless in her heart, but she was more interested at this time, people from the big countries in the East are really smart, they can actually come up with these methods to complete the operation of this kind of vehicle? I want to see how great the potential of Mercedes-Benz heavy trucks is.

Of course, a few years later, the answer was revealed, domestic heavy trucks began to compete, Mercedes-Benz heavy trucks overload capacity has also been recognized by the industry, up to 240 tons of total weight, so that everyone is jaw-dropping.

This is a crazy era, it is a product of the period, Dora can run fast, in order to make his pocket bulge as soon as possible, in order to be able to develop the economy rapidly.

Qin Zhenhua didn't think there was anything wrong with this.

"If you encounter a long downhill and overheated brakes, how to solve it?" Mia raised another problem, now, since Steyr's overloaded transportation has appeared, then, it must be solved, for the driver, the problem of overheating caused by continuous braking during the long downhill seems to be unsolvable.

"It's a simple question, water." Wang Erzhu said: "We don't need to think about this, when it comes to the user, I will weld a water tank, and while walking, I will pour water on the brake drum." ”

This is the wisdom of the people of the big eastern country, since the temperature of the brake drum is high, then the heat dissipation, the normal way is not good, then use the way of water to solve, what tall things, we can't afford to use it, stupid methods can also solve the problem.
