Mercedes-Benz uses the most advanced variable-section beam, which is different from the front and rear, and has various arcs, which can achieve the required load-bearing capacity while reducing weight to the maximum extent.
But Steyr did not do this. They all aim to be simple and practical. They use beams made of ordinary stamped channel steel. The shape is exactly the same and the bearing capacity is insufficient, a layer of beams will be nested inside.
To increase strength, this method is the simplest and most direct. In comparison, the disadvantage is that it will gain weight.
However, lightweight is not yet advocated. For a heavy truck, do you still need to care about the weight brought by adding a layer of beam?
Of course not!
At this moment, everyone's eyes began to shine.
This method is obviously more suitable for domestic use, because it can be processed without purchasing special equipment. Moreover, this manufacturing method is quite simple and completely meets our own industrial standards and does not require an increase in production burden.
Advancedness comes at the cost of advancedness. Although the Steyr heavy truck in front of us is backward, it still achieves the design goals that need to be achieved through clever design.
Walking forward along the production line, the frame begins to install various components, engines, gearboxes, and axles. As we walk, Maltzah will introduce it to everyone.
"The engine we use, codenamed WD615, is developed based on WD614 and W815 engines and is the main power system we will adopt in the future."
For everyone, the most critical link in the production of heavy trucks is the engine. It is the heart of a heavy truck. Mercedes-Benz's engine technology is advanced, but the processing is more precise and requires more equipment. So, what about the engine here?
W represents water cooling, D represents diesel, so this is a water-cooled diesel engine. As for the three-digit number behind, 6 represents the number of cylinders, and 14 represents the displacement, which is the same as the naming method of many engines.
This WD615 engine is also the most advanced engine just developed in 1978, representing Steyr's highest technical standard.
"With the development of the times, European commercial vehicles are developing towards the direction of big strokes. Our engine is the product of this idea. Its cylinder bore is 126mm and its stroke is 130mm. In fact, if calculated, single
The cylinder should have reached about 1.6 liters.”
The domestic Yellow River heavy truck directly uses marine diesel engines. Although it can achieve the power requirement of 200 horsepower, it is still very different from that of automobiles. The pursuit of marines is power, automobiles, and pursuit of
It's torque.
The power determines the maximum speed, while the torque determines the acceleration ability. The same horsepower is the same. Gasoline cars can run faster and diesel cars can pull more. That's the reason.
This advanced engine has also opened everyone's eyes. In Europe, the concept of modularity has begun to be popular. The same is true for this WD615 series engine. With other components unchanged, it only depends on changing the engine's air intake method.
and injection system to change the power of the engine, the power coverage range can range from 200 horsepower to 370 horsepower, and cover a variety of models such as high-speed engines and high-torque engines, so as to range from 16 tons of two-axle cars to 40 tons of
Heavy trucks can be covered.
"Now, what we assembled is mainly because he installed a turbocharger on the WD615.00 and increased the fuel injection. In this way, its power increased from 200 horsepower to 260 horsepower, at 1600 rpm
It can output 829 Nm of torque."
"This engine has a really good performance!" Hearing the other party's introduction, Nie Yunkai couldn't help but sigh and said, "I don't know how many times better than his own marine diesel engine."
Nie Yun looked at the diesel engine with his eyes open, and hope was already ignited in his heart.
If you continue to introduce the modular idea, it makes people sigh that this kind of car is not only modular, but also other devices. It uses 5 engines with different power, 4 transmissions, and 3
It combines rear axle, 2 front axles, 2 clutches, 2 steering gears and a set of gas circuit modules to create dozens of models of seven levels. It can be said that as long as it is introduced, it can fully meet domestic needs, although it cannot be combined with
Compared with Mercedes-Benz heavy trucks, however, as far as we look at it, the technical level of the entire heavy truck is already at the world's advanced level.
Everyone nodded from the production line. The unknown Austria not only has the blue Danube River, but also has the reputation of a country of music, but also has this technologically advanced heavy truck!
After visiting the entire production line, everyone already had plans in their minds. Now, what is left depends on whether their conditions can be agreed.
In the evening, Steyr's side organized a huge welcome dinner, which was in sharp contrast with the Mercedes-Benz's side.
While raising his glass to drink, Mr. Yang threw out this topic.
"We are quite satisfied with Steyr Heavy Truck and hope to introduce a complete set of production technology to produce it in our country. I wonder what your opinion is?"
Mercedes-Benz is unwilling to export technology, and other major manufacturers are unwilling to do so. So, can Steyr make this opening?
"Of course." Marchahe nodded: "We are willing to export our most advanced technology to the Eastern powers, so that our Steyr heavy trucks can bloom everywhere in the Eastern powers."
Steyr is just a small brand in Europe, mainly meeting domestic use and not even exporting much. This time, taking advantage of the opportunity to seize the market of a world's largest country with the largest population. Why not?
"However." Feizmaier, the director of the automobile factory next to him, said: "Considering your domestic industrial foundation, I suggest that you first use CDK to produce, and then gradually expand the proportion of independent manufacturing parts, and finally achieve the goal of achieving
It is unrealistic to produce all of them by yourself if you require full self-production from the beginning.”
"CDK?" It was the first time everyone heard about this introduction that they could not help but look at curiously. Could it be that these Austrians were unwilling to speak out, so they came up with a new way?
"This method is called bulk assembly." Qin Zhenhua briefly introduced to everyone: "Our domestic vehicle manufacturers first import all bulk parts from the supporting manufacturers to assemble them in our country.
This can be produced in the fastest way.”
Look at the Austrians, they also need to make money, but the plan proposed by others is the best, and only then can you accept it, and win-win cooperation. How great would it be if the Mercedes-Benz heavy truck also proposed this plan!
