In the middle of the night, finally, a qualified mold came down from the CNC machine, Qin Zhenhua's hands trembled a little, his eyes were red, he measured it carefully, and finally breathed a sigh of relief.

Next, it is to find a special pouring workshop and use a special alloy to pour it out!

At this time, the advantages of the maintenance workshop are shown, because the workers in this workshop are transferred from other workshops, and they will do whatever the craft, fitters, welders, lathes, and some have stayed in the pouring workshop.

Then, it is the other parts, the most difficult parts are made, and the others are simple, a week later, Qin Zhenhua's eyes are red like rabbits, but a completely identical imitation is finally created, and the next step is to test it after installation.

Now, those people in the R&D room want to grab the credit, there is no way, this hydraulic torque converter is imitated by surveying and mapping in our maintenance workshop, and the credit has our share.

Otherwise, if an apprentice like Qin Zhenhua goes to the R&D room, the credit will be divided among them, and it is estimated that he will not even be qualified to go up his name on the commendation letter of celebration.

The R&D room is also quite nervous, if it can't produce results, once the superior gets annoyed, it may be handed over to other factories to imitate, and the task that is easy to get must not be messed up, Song Weize and Ma Panshan patted their chests.

Now, with a smile on his face, Song Weize watched his men put the imitation back into the M48 tank.

Once the imitation is complete, it is time to test, and the best test platform, of course, is the M48 tank, as long as your own test imitation works well on it, it means that it has succeeded.

"Director Song, the installation is in place." Du Youwen was also very happy at this time, although he was quite unhappy when coordinating the torque converter, but that thing was difficult to process, and it was really impossible to get it out in the R&D room.

Although it has also imitated high-horsepower in the past, it is used in locomotives, but the volume is large, and the accuracy requirements are not high.

After a day's installation, it was already sunset at this time, and everyone was holding back a momentum, Song Weize said: "Start, test a lap, and then call it a day." ”

The detailed test has to go to the shooting range, run hundreds of kilometers, test the reliability, and for now, watch it move first.

"Yes." Du Youwen replied, got into the inside of the tank, and with the roar of the motor, the sound of da-da, the engine started.

M48 tank has a variety of models, at the beginning, the use of a gasoline engine, is a strange design, although the fuel tank is large enough, but, the maximum travel is only more than 100 kilometers, absolute chicken ribs, in contrast, diesel tanks, often is the maximum travel of three or four hundred kilometers.

The U.S. Army was also fed up, and in the later period, it finally replaced the gasoline engine with a diesel engine, the AVDS-1790-2A diesel engine of the Continental Corporation, which extended the maximum range of this tank to more than 400 kilometers at once.

And now, the model of this M48 tank is M48A3, the version of the improved diesel engine in the later stage, Du Youwen is not the first time to start, skillfully pushed to the forward gear of the automatic transmission, and the rest is to step on the accelerator.

This powertrain is so good that there are only two gears forward, yes, just two, even if it's a 212 jeep, or three in and one down, look at the sedans of later generations, automatic transmissions, to say the least, there must be five or six gears, and even nine gears.

However, this is not a thing, if there are more gears, it is troublesome, and the operation is complicated, this gearbox is electro-hydraulic controlled, it can be automatic, it can also be manual, anyway, there are two gears, high-grade area and low-gear area, and, due to the role of the torque converter, you can start directly with high-grade, and the rest will be handed over to the torque converter.

For tank soldiers, it is also very enjoyable to start such a tank, especially when it starts directly at the high end, it feels like a catapult, and there is no need to change gears, and there is no loss of power.

Du Youwen's feet slowly stepped on the accelerator pedal, gradually increasing the force, the roar of the engine in the tail increased, in this roar, he felt the tank shaking, and then, it was time to move forward.

The people below also stood more than ten meters away and watched, watching the tracks begin to shake, and then, it was time to move forward, their imitations can achieve the effectiveness of the original products!

But how not to move forward? Looking at it with a blank eye, the tank just can't move.

Du Youwen was very surprised, the strength of the accelerator pedal under his feet was getting bigger and bigger, the engine behind roared, running at high speed, it had reached the maximum speed, and the tank still couldn't move!

Du Youwen could only release the throttle, and after the rev slowed down to idle, he pushed it to the low gear, which was said to be no problem with the operation just now, but now, since the high-end tank can't move, then try the low gear.

The speed continued to increase, increase, and the tracks of the tank seemed to be shaking a few times, but the tank just couldn't go!

Weird, what's going on?

The onlookers around frowned even more, and Song Weize shouted below: "Are you in the gear?" ”

If you only hit the throttle and the tank doesn't move, it's like you're in neutral.

"Of course I did." Du Youwen said: "I feel that the tank has a tendency to move forward, but it just can't move." ”

If I want to hang neutral, then the tank doesn't move at all, okay, now, I can't move if I want to, so there must be a problem with the transmission system!

"Check!" Song Weize shouted.

Turned off the engine, turned off the engine, and opened the lid at the back, Du Youwen put his hand in, and immediately howled: "It's so hot!" ”

The part where he sticks in, which is exactly the part where the gearbox and the engine are connected, is the torque converter! Now, the shell is scarily hot, and the hands are burned out of two bubbles.

He shook his hand and said, "The problem with the torque converter, it only heats up, it can't reliably transmit power!" Qin Zhenhua is a stupid person, he can only brag! ”

Hung up the gear, the tank does not move, indicating that the power can not be transmitted, if it is the previous fault statement, that is, the clutch is broken, now, the torque converter replaces the clutch, so, it must be the torque converter is broken, so hot, the energy of the engine, are used to stir the hydraulic oil inside, and the power is not transmitted to the back!

Song Weize's face was extremely ugly.

"Let's go, go to him and ask him for his guilt!" Du Youwen shouted: "Maintenance workshop, this is the key to our R&D room!" Qin Zhenhua is the culprit! ”
