More than a dozen technicians and workers went into battle together to conduct a comprehensive inspection of the No. 7 prototype, dismantle it on the spot, and find out the original problem.

Li Lu and Ma Jintao stood on the left side of the body, both staring at the left front wheel. The problem is definitely here, but what exactly went wrong is still to be checked.

As a result, the worker who had not been under the car for a while quickly got out and said, "The load-bearing shaft of the left wheel cracked very badly, and it was about to break, just a little bit." ”

Ma Jintao was stunned for a moment, and he immediately understood, and he said to Li Lu, "The deformation of the frame has affected the pipeline, and there is only this possibility, otherwise several systems will not all fail." ”

"Broken shaft?" Li Lu frowned and blurted out, "-Ford's production line!" ”

"It doesn't have much to do with the production line." Ma Jintao said seriously, "Either the problem is in the material, or there is a problem in processing." ”

As he spoke, he rolled up his sleeves and went on the field himself.

By this time, the workers had already used a few jacks to jack up the No. 7 prototype, and it took some effort to remove the left front wheel. Ma Jintao didn't wear gloves either, squatted there and checked them carefully, and sure enough, none of them surprised him.

While wiping his hands, Ma Jintao said to Li Lu, "The brake line has been squeezed, and the hydraulic system of the steering mechanism, the clutch pedal lever, and the driver's seat have also been affected." ”

The worker handed over a dismantled crankshaft part, and Ma Jintao took it in his hand and said, "This is it." ”

Li Lu took it and looked at it carefully, and it was obvious that the crankshaft parts larger than the fist had been seriously deformed, which was caused by the inability to withstand the violent impact in high-intensity exercise.

"A problem with the material?" Li Lu asked.

Ma Jintao shook his head and said, "It should be a problem of processing." In my opinion, it is necessary to use a new machine for uniform processing, which can greatly improve the accuracy of processing. The occlusion accuracy is in line with the standard, and such a problem can be eliminated. ”

Li Lu nodded, "You're talking about a five-axis linkage CNC machine, well, then use it, and transfer one out to process this part." ”

Ma Jintao said with a smile, "Then it's not just about processing this one part, many parts can be used with new machines, and it is estimated that the quality can be improved by a grade." ”

The zero workshop where the five-axis linkage CNC machine tool is located was assigned to Yao Taihang, and all four sets of machine tools and equipment were given to him. Li Lu didn't speak, and no one dared to hit the idea of those machine tools. Ma Jintao knew that it was the main machine tool equipment for aero engines, and aero engines were obviously important in any other project, so he would not easily make such a request.

At the moment, the No. 7 prototype car has exposed such a serious problem, and he can't take care of it much.

Li Lu said, "Fuji Heavy Industries' two sets of five-axis linkage CNC machine tool systems are also about to arrive, and when the time comes, the two sets will be handed over to the Ministry of Automobiles." ”

"This one couldn't be better." Ma Jintao said with a smile.

Ma Jintao is in charge of the automobile research and development of the Red Star Factory, and his two students, Jiang Hao is responsible for the BMW X1 project, and Liu Guobing is responsible for the localization project of the 2.0-liter four-cylinder gasoline engine.

Ma Jintao looked at the No. 7 prototype car that had been unloaded, and said solemnly, "I think the layout of the pipeline still needs to be carefully considered." ”

Several systems fail at the same time, and the problem is very serious.

Li Lu asked, "In addition, can you add a backup braking system?" The braking system is the most critical. As long as this car runs on the road, it is more than ten or twenty lives, and the braking system must be placed in the most important position. ”

He thought for a while and said, "I think the test intensity of the braking system should be increased, and the high-intensity test should be carried out for a long time for a month or two." Refer to the test of the tank, organize a team, select a few representative areas, and test the actual use of the vehicle in various climatic zones and various terrains. ”

"That's a lot of money." Ma Jintao said with a wry smile, "Civilian vehicles are required according to military standards, and I don't think there is any need for this." ”

Li Lu waved his hand, "It's necessary." Relatively speaking, the minibus has a higher degree of independent research and development than the BMW X1, and although this chassis is based on the technical characteristics of the chassis of Hiace and Kosda, it is completely designed by us. This is important. ”

Ma Jintao doesn't think so. No matter how good the performance of the BMW X1 is, the three major parts are imported parts, and even although it is based on the chassis of the 212 Jeep, it is also a reference to the LC70 to make some improvements. So inside the Red Star Factory, even everyone themselves don't think that it is a self-developed car.

Only the chassis of the minibus has poured a lot of effort into everyone, which is the real independent research and development. Obviously, the technicians of the Red Star Factory already have the idea of breaking away from the Hiace chassis, just like Kosda, and just use this as a reference.

In fact, this is also the main factor that causes the chassis to not meet the stability requirements so far - because everyone has to make a chassis with its own technical characteristics, rather than blindly copying it.

"In that case, I suggest asking the Red Star Defense side to help, they have a lot of experience in testing military vehicles." Ma Jintao said with a smile, "Moreover, you have to find someone else to be responsible for this matter, and I don't have time to follow up." ”

It's not so much that he doesn't have time to follow up, but that Ma Jintao stays away from matters involving administration. He is the chief engineer of the Red Star Factory, the director of the Materials Research Institute, and at the same time is in charge of all automotive research and development projects, but he never bothered about administrative and personnel matters, he worked out the technical aspects.

The formation of a commissioning team is undoubtedly a big deal, and in addition to the team that provides technical support, a strong administrative team is also required. For a team that often travels all over the country to conduct field tests, Ma Jintao knows how critical the administration and personnel are.

Li Lu said, "Well, I'll find someone to be in charge." ”

He is determined to get the project of the minibus to the ground, which is carried out according to the highest standards at present, which is a test for the team of the Red Star Factory. If you can't even get a handle on the medium-sized bus project, don't talk about tanks and armored vehicles.

"Horse worker, I have an idea about standards." Li Lu and Ma Jintao walked back and talked at the same time, and the dismantling site was still busy.

Ma Jintao smiled, "You want to formulate a system?" ”

"Yes."

Li Lu pondered and said, "As far as I know, we don't have a standardized military standard system in China, and the performance indicators of many weapons and equipment are put forward by the troops and then the manufacturers follow the requirements, and the requirements of each army are different, and even the troops in the north and the south are different. However, all of these have one thing in common – a lack of basic standards. As a result, the standards of many domestic weapons and equipment vary greatly. ”

He paused and continued, "I think so, the Red Star Factory and the Red Star Defense Company have worked together to develop a whole set of military standard systems. Hongxing Factory can use this standard system as a reference to derive a set of standard systems for civilian vehicles. First of all, this has been of great help to several of our recent automotive R&D projects. ”

Ma Jintao nodded dryly, "I completely agree." With standards, all work has a clear basis, which is very beneficial to future R&D and production. ”

Li Lu said, "Then do it, you contact Pei Gong, and concentrate on getting the military standard system out first, of course, mainly the standard of ground defense equipment." ”

"Okay, I'll do that." Ma Jintao readily agreed.

If you ask him to recommend someone to do administration, he has absolutely no idea, but if it's something related to technology, then he will be very straightforward.

The ground defense equipment part of the Huaxia military standard system was born in the hands of the Red Star Factory.
