If you want to win customer recognition, you have to constantly consider customer needs.
Now, as the 9910 project is approaching, it is no longer easy for many projects to join again. The technicians of Yimai Factory are looking forward to the emergence of the Big Eighth Round on the parade.
Of course, you still can’t hurry everything, you have to take one step at a time and keep your feet on the ground.
At the same time, when Qin Zhenhua was wandering around the automobile branch, he found that there were really a lot of things he had developed in the automobile branch.
"When will our automobile branch start production and dragging?" When we entered a workshop and saw the trailer, Qin Zhenhua asked Wang Erzhu curiously.
The first machine factory produces cars, but only produces the front.
In this era, road transportation has gradually changed to trailers, especially semi-trailers. The characteristic of this kind of car is that the front of the car is short and there is no cargo box. A long cargo box behind it is directly pressed on the rear axle of the front of the car, with
A winch can rotate, and the structure formed in this way is a semi-hanger. In the past, a car in front and a car in the back is a full car.
The full-hooked car has a flexible steering and strong carrying capacity, but it is inconvenient to operate. Especially as the speed increases, the brake performance will decrease rapidly. If the front of the car is braked and the trailer does not brake, then the trailer will come across.
If it is on a highway, the trailer will always sway left and right during the driving process of this kind of fully-hanged car, which is a great challenge for road safety.
Therefore, all trailers have begun to be eliminated, and semi-trailers have become the mainstream. Most of the Mercedes-Benz heavy trucks produced by the first machine factory are semi-trailer fronts.
The first machine factory only produces the front of the cargo box, not the rear cargo box. It is separate and independent. The trailer is produced by a special trailer manufacturer. After all, its technical content is low, and the beams, carriages, axles, etc. are combined in
Together, it's a trailer.
Now, Qin Zhenhua was certainly curious when he saw such a semi-trailer trailer in the automobile branch.
However, it is still very different from ordinary trailers. First of all, it is very long, and ordinary trailers are only twelve or thirteen meters. The trailer in front of you looks like it is nearly twenty meters long. Such a large trailer is
What supplies are you pulling?
Not only is it super long, it seems to be a little wide. Moreover, the trailer axle below has four bridges, which means that the cargo that it wants is also very large. Because of its large weight, it requires an extra shaft.
Ordinary trailers use three-axis structures.
What is it used for?
Just as Qin Zhenhua looked down at the axle, suddenly, a person came out of the axle. When the man saw Qin Zhenhua, he was also stunned: "Director Qin?"
"Director Liu?" Qin Zhenhua asked strangely. He knew this person, Liu Qianjin, the director of the R&D office of Hanyang Factory. In the past, there were some technical problems. I came to Yimai Factory for help and met him.
In recent years, Qin Zhenhua has been traveling back and forth and rarely stayed in the factory, so he has not had much contact.
"It's already Director Liu." Wang Erzhu said: "Two years ago, the old director of Hanyang Factory retired, and Director Liu came up."
"Okay, not bad." Qin Zhenhua said: "Director Liu, we are all at the same level in the future. If you have any questions and need help, just say it."
Liu Qianjin smiled and said, "Director Qin, you are joking. Our Hanyang factory is just a few bites of food from the army. How can we compare with your machine factory? Look at your automobile branch and produce it.
Products, both military and civilians, have achieved good economic benefits by rushing to the development of the country's economy. Looking at us, we have no ability to invest in the civilian direction at all."
They all make cars, and the gap is also very big. The trailers built by the Hanyang factory are only for military use and are not bought by the private sector. They can reach a maximum of 1,000 vehicles a year. Let’s look at the automobile branch of the one-machine factory.
There are tens of thousands of vehicles produced and sold, and the gap is too big.
Liu Qianjin knew that there was a big reason here, that is, the difference between military and civilians. Military uses are strong and durable, and they cannot be damaged no matter what bad road conditions are. Civilians pay attention to cheap and save money, especially low fuel consumption.
These are two different directions, so they cannot mix them. They put their military trucks into the civilian market, and no one is willing to ask for them.
Fortunately, the Hanyang car in the army had a good cup, otherwise they would probably be eliminated.
Hearing Liu Qianjin's words, Qin Zhenhua nodded: "Well, if you want to invest in the civilian market, then you have to make a big change, which will lose the military market. I think you are still in the military trucks.
Research in the field is the most suitable.”
To be honest, Qin Zhenhua never beat around the bush. Hanyang Factory's technical capabilities are just like that. It can only attack one direction and cover everything. It has no ability at all. In the end, they can only make their products loose.
"Yes, we have also decided to only follow the military path." Liu Qianjin said: "In the future, when it comes to military trade, it will be able to make money if you can sell it abroad."
Qin Zhenhua nodded and asked, "Is this trailer your product?"
"Yes, ours, but because there are many technical problems that cannot be solved, I came here. I hope to use the R&D power of the One Machine Factory to complete the breakthrough." Liu Qianjin said.
"Technical question?" Qin Zhenhua felt strange: "What are the technical problems of a trailer?"
"We want to improve the passing of the trailer." Liu Qianjin said: "So, I want to give the trailer a driving force."
Trailers are an important way of road transportation, but their shortcomings are also very obvious. When walking on bad roads, the passability is very poor. After all, trailers have no power and rely only on the front locomotive. Simply put, if
The driving wheels of the trailer in front slipped, and the entire trailer lost power.
This situation is often seen in the winter in the north when you go uphill.
However, it would be difficult to give the trailer a driving force.
After all, the trailer is alive and the front. If you want to push the trailer forward, how can you connect the power? Moreover, after connecting, how can you keep the front and back consistent? These are all big problems, almost comparable to the consistency of the hybrid system in later generations.
There is a problem.
"This is not easy. The traction head in front can be driven by all-wheels. By the way, I remember that a few years ago, didn't you have 8*8 traction heads?" Qin Zhenhua said.
"Yes, we just use that puller, but we still want the trailer behind to have the driving capability."
