The test driver pressed the brake pedal to the end, and the four tires of the little white rabbit were suddenly dragged alive, and the speed of rotation slowed down all of a sudden, leaving two very clear tire marks on the ground with a half-sliding.

Li Lu was stunned and subconsciously said, "ABS system? ”

"What ABC?" Liu Guobing asked.

"It's the anti-lock braking system." Li Luzheng wanted to explain in detail, and suddenly saw Liu Guobing's confused gaze, he suddenly realized that the current ABS system is still a high-tech technology, although many automobile companies have developed similar systems with their own characteristics, but because of the cost of the problem, it is difficult to popularize.

The people in the automobile industry in China don't even know what it is.

Waving his hand, Li Lu said, "I'll talk about this ABS in detail later." ”

The reason why he asked this was because he saw that the prototype No. 1 of the White Rabbit did not slip sideways after it was urgently formulated. It can be seen that the braking force of the White Rabbit prototype No. 1 is very strong, but in the case of high speed, the stronger the braking force, the easier it is to produce side slip.

Hence the emergence of the ABS system.

Li Lu carefully looked at the prototype No. 1 car of the Little White Rabbit, so he probably understood. It looks like the braking force is very powerful, but in fact, the four wheels are not locked, and the braking force does not break through the friction between the tires and the ground, and of course there is no such phenomenon as side slippage.

The impact of vehicle weight is significant.

Suddenly, Li Lu smiled inexplicably - it is obviously not necessary for the combat vehicle to be loaded with an ABS system.

"What about seat belts?".

When Li Lu saw that the test driver's head almost smacked on the windshield, he subconsciously asked.

Liu Guobing wondered, what's wrong with the third brother?

"Third brother, there is no requirement in this regard, besides, this is a military vehicle, and the seat belt will bring trouble to the operation." Liu Guobing said.

"How did the test riders who were injured some time ago cause?" Li Lu suddenly asked.

Some time ago, Li Yaohua reported to him that a test driver was injured during the test drive, and he didn't ask how he was injured at the time, but now it seems that eighty percent of the seat belts are related.

Liu Guobing said, "When I tested the braking performance, I collided with the front windshield and the driver's platform, some of which were for the head and some for the upper part of the body. Another was thrown out and fell to the ground and was injured. ”

Li Lu frowned, and then slowly stretched.

At present, there is no legal requirement in this area, and it will not be until 1992 that regulations will be issued to require the production of vehicles, including cars, jeeps, vans, and mini cars, to use seat belts, and the traffic law has made clear requirements, drivers and passengers must use seat belts.

In other words, vehicles within the scope of production at this time can be sold without seat belts. The large number of CA10s that Li Lu bought did not have any seat belts.

Li Lu thought carefully about the working principle of the pretensioned seat belt, but unfortunately, he was not a professional and did not understand very clearly, he thought about it for a while, took out a pen, and said to Liu Guobing, "Give me a piece of paper." ”

Liu Guobing hurriedly took out a notebook and flipped out a blank page and handed it over, Li Lu took it, and said while drawing on it, "The pre-tensioned seat belt, three-point type, is a right triangle when fastened." The so-called pretensioning type is the moment when the vehicle is impacted, the retraction device tightens the seat belt and fixes the person's body on the seat. You have to think of a way to do that. ”

Hearing this, Liu Guobing's eyes lit up and said, "This idea is too powerful." If such a device exists, it will greatly reduce the chance of collision between the occupants and the front windshield. Occupants are basically not thrown out of the car. ”

Li Lu said, "In research and research, safety should be put first, even if it is a military vehicle." ”

"Understood." Liu Guobing took back the notebook and wrote down Li Lu's instructions on it.

Over there, technicians have already flocked to inspect the White Rabbit prototype No. 1 to check whether the various systems are in order. Sun Jiangtao strode over and listened to the voice. The sound of the engine is normal, powerful and powerful, and everyone can only hear the sound of da-da-da.

Li Lu and Liu Guobing walked over, and Liu Guobing took out a measuring stick and began to measure the integrity of the frame. After such an intensive test run, it is unknown whether the elongated frame meets the standard. The White Rabbit prototype No. 1 is open-topped, and the decorative panels have not yet been installed, not even the lighting system. The purpose of this test is to check the condition of the machinery.

Sun Jiangtao suddenly said to the workers, "Hold up the rear axle." ”

Several workers immediately used jacks to push against both sides of the rear axle and prop up the vehicle. Sun Jiangtao rolled up his sleeves, took the skateboard and lay down, the worker handed him a hammer, and as soon as he supported his feet, he slid under the car.

Li Lu listened intently, and could faintly hear a trace of noise, not the sound of the engine, it was covered and difficult to hear.

After a while, Sun Jiangtao slipped out and said, "Wrench." ”

The worker hurriedly handed it over.

Sun Jiangtao slid in again, this time for a longer time, and when he came out again, there were some more parts under the car. He said, "Take the half shaft out." ”

Two workers hurriedly got under the car and spent more than ten minutes to complete the next work. A worker handed the half shaft to Sun Jiangtao, who handed it to Li Lu and said, "The noise is coming from this thing." ”

Li Lu took a closer look, and the position of the gear had been violently worn, with powdery chips and oil sticking together, and he smelled something similar to burning, he said, "This half shaft is wasted." What's the problem? ”

Liu Guobing walked over, looked carefully, and looked at Sun Jiangtao.

Sun Jiangtao said, "The strength of the steel is not enough. The half-shaft transmits torque before the gearbox reducer and the driving wheel, and if the strength is not enough, it will wear out severely. The clutch is up to par with the torsional resistance required, but you're missing these key parts of the rear axle. ”

Liu Guobing patted his forehead and said, "In this way, the entire rear axle must be manufactured with higher strength steel." ”

Li Lu asked, "Can our lightweight special steel be used?" ”

Liu Guobing reported, "The clutch is made of lightweight special steel, which greatly improves the torsional resistance. The rear axle is made of steel of this model, which is obviously no problem. This allows the weight of the vehicle to be controlled. ”

Li Lu said simply, "Lightweight special steel can be used." ”

Sun Jiangtao smiled and said, "Xiao Li, your idea is good, but don't forget, in this way, the cost will increase significantly." ”

Shaking his head, Li Lu said very seriously, "Cost is not a problem, we have profits." As the first self-developed model in the true sense of the Red Star Factory, the quality must be absolutely excellent. Moreover, this is a military light off-road platform to be exported, and the quality is not good, which will affect the image of our country. ”

"Well, this is a big deal, and you must not let AIA use something of poor quality." Sun Jiangtao thought so.

Liu Guobing hesitated and asked, "Third brother, in this case, the output of lightweight special steel must be increased." Most of the capacity of the steelmaking plant of Red Star Defense is supplied with Asian Tiger tanks and 59 modifications, and there are not many of them in our hands. ”

Li Lu said, "I will solve the problem of production capacity, you seize the time to improve, and there is not much time to deliver." ”

"Understood!"
