Chapter 2152: Solve the problem

The car was dragged back to the garage.
The whole car has completely got rid of the traces of the previous Steyr heavy trucks, and the entire cab looks quite modern. It can be said that this heavy truck is a leading product for the heavy truck industry in Han to go abroad and to the world. Up.
When will it truly become a big country? Of course, it is to make Han Chinese manufacturing flood the world. Only when the industry is strong can it be truly strong. Now, we are on this road, step by step.
After entering the garage, Heribala personally opened the front turning mechanism, and then, pressing the button, the cab was turned over amidst the sound of the electric motor.
For heavy trucks with flat heads, the engine is under the bottom, so if you want to repair the engine, you need to lift the cab. At the beginning, the cab is fixed. This design makes maintenance difficult. , Or even dismantle the entire cab.
Later, the cab was designed to be flipped, and the cab was flipped forward to make room. Of course, this would also increase mechanical complexity.
Turn it over, in addition to designing the front hinge mechanism, you also need to use a jack, support a stick on the back hydraulic pump, and flip the cab up one by one. In a saying, this is called a basket.
If the engine often needs maintenance, this is definitely a laborious task. Therefore, for the convenience of the user, a new device is designed here, an electric turning mechanism. As long as the button is pressed, the electric motor can turn the cab upside down.
Qin Guan gave a thumbs up to this design. Yes, if our heavy trucks are to be high-end, we must consider our customers. In this regard, we have already come to the fore.
In fact, if it’s just a problem with the gearbox, there is no need to start the cab. After all, the engine is under the cab and the gearbox is behind. For this type of tractor, it is directly exposed to the outside. However, If you want to overhaul, it's more convenient to fight like this, and besides, it doesn't take much time.
Hold it up, lock it, and several engineers went up and started to disassemble the clutch. At this time, there was still a smell of burnt inside.
"Sure enough, it has been burned." An engineer said, using a crowbar to move the clutch plate from the side seam.
The engine is always rotating, but the wheels are not. Therefore, in the transmission of power, there is a mechanism that needs to cut off the power and combine the power at any time. This is the clutch. Of course, in the automatic transmission car of AT, the clutch component is The torque converter has been replaced.
In a dual-clutch car, if the clutch keeps contacting and disengaging for a long time, it will burn the clutch and cause serious accidents. In order to solve this problem, the engineer used the method to soak the clutch disc in liquid. Heat dissipation, this is the wet dual clutch, which is a relatively stable solution.
It’s impossible for this type of heavy truck to use this method. The power it needs to transmit is too great, and the clutch disc is also huge. If all is soaked in oil, the weight is too large. In fact, it uses the original The clutch is only equipped with a pneumatic thrust device, which is used to replace a person’s left foot. In a manual transmission car, the left foot is used to control the clutch.
The principle is very simple, but the operation is complicated. For example, with human feet, there is a very special operation, which is half-clutching. When the clutch plate starts to be separated and becomes integrated, the movement needs to be slow and gentle. The better, if the car is not obvious yet, for heavy trucks, if this action cannot be slowed down, then it will not be able to start at all. When some drivers of small cars go to drive a large truck, they simply cannot drive. For this reason.
Employing operations can be repeated training, but this system?
The system is not as smart as people.
The clutch of the heavy truck is very heavy, and the compression spring on it is very elastic. On the heavy truck, the clutch is also a power-assisting method. Now, it has been replaced with pneumatic operation.
This air pressure operation is very special. It either does not move or swipes it all at once. The same is true for heavy trucks. When braking, you either do not step on or trample to death. You must not step on half as you would when driving a car. Otherwise, , The compressed air in the brake will always be in a released state, and it won’t be long before the air is out of it, so it’s sad.
This thing is too violent. Therefore, when the clutch is pushed, it either does not move or it goes up all at once. The reaction to the operation is a serious setback. This is just an empty car. If it is heavily loaded, It was a nightmare. He Ribala watched as a group of engineers began to disassemble the car, and at the same time began to introduce Qin Guan, the situation now is like this.
After listening to Heribala's introduction, Qin Guan also understood roughly how to overcome this technical problem? This is very simple, go to the cemetery to find information.
There are no civilian vehicles, but there are military vehicles. With the continuous development of military vehicles, this kind of AMT transmission has begun to be popularized. There are also military vehicles. So, when everyone was studying how to solve the problem, Qin Guan quickly entered the system. , Find out a copy of the information in the system.
How to deal with it? It's very simple.
If you want to use compressed air directly, it is very straightforward. It either does not move or is combined at once. In contrast, the hydraulic pressure is very gentle. Therefore, this type of AMT heavy truck gearbox is not directly combined with air pressure. To separate, use air pressure to act on the hydraulic oil to provide pressure to the hydraulic oil, and then use the hydraulic oil to push the clutch to operate, plus reasonable adjustments, and it comes out.
"Here I have some information for you to study and study." Qin Guan gestured to the Xiucai. In Xiucai's box, there have been some additional information, not only the design of the clutch, but also the data adjustment of some gearboxes behind. With it, it is naturally easier.
When the engineers got the information, they were all very excited. President Qin really solved the problem. Why didn't they expect that they could change this way of thinking so that the clutch can be made more stable!
In addition, the gearbox adjustment and shift logic are also very important. President Qin solved the big problem at once!
Wait, why is there an extra sensor here? What is this for? Don’t bother Mr. Qin, research it yourself, yes, this is a posture sensor for use when going uphill, yes, these ideas for solving problems are all correct!
