"The transmission and clutch are two things, like the engine, and of course they are also items that must be changed. In addition, the gear cooling system also needs to be strengthened. The clutch is modified with high-temperature resistant and high-horsepower and high-torque output products, because when the original clutch is subjected to high torque output for a long time, it will burn out at high temperature. Xiao Chenxi said to Zhang Lan, "Temperature is the third issue that needs to be considered in the racing car in addition to power and heat dissipation. ”

"Of course, it is impossible to use everything else's, and the braking system used on this car is our own masterpiece of the Alice Group: the large-diameter fully ventilated disc composite ceramic brake system! Unprecedented six-piston calipers are used, and two independent six-piston caliper brakes per disc are installed. Such equipment has not even appeared in F1 jams. For this, Xiao Chenxi is obviously very proud, "Our Alice Group's composite ceramic brake system is currently the world's best performance brake system, the vast majority of the models participating in the Dakar Rally, are also using our company's large-diameter fully ventilated disc composite ceramic brake system, just by selling the brake system, we can basically make all the car modification costs back this time, and there is a lot of surplus." ”

At this, Alice was overjoyed.

"As for the desert tires we chose for our racing cars, they are Michelin's Belluchi desert racing tires with which we have always had a good relationship. And in order to better adapt to the extreme conditions of the desert, all of our cars have automatic tyre inflation and deflation functions. Alice then added.

Zhang Lan nodded, he knew very well that the vehicle driving in the desert was different from driving on the highway or even the dirt road, and the racing car walking in the desert could increase the ground contact area of the tire by reducing the tire pressure when going up the sand slope. Facilitates vehicle climbing. When driving normally and fast, it is necessary to make up the air pressure to facilitate handling. Therefore, it is very important to have the function of automatic charging and deflation, which can greatly reduce the trouble of manually inflating and deflating when getting off the car, and it is much faster, which means that the driver can save more time, which is equivalent to improving his speed and performance in disguise.

"Raise the car up, and I'll look at the structure of the underbody." Zhang Lan said to Xiao Chenxi.

Hearing Zhang Lan say this, Xiao Chenxi nodded, and the car had risen to the height above Zhang Lan's head as he spoke, just enough for Zhang Lan to look up slightly to see the various structures under the car.

At first glance, Zhang Lan was dazzled by the various dense protective plates at the bottom of the car: in order to further strengthen the protection of the bottom of the engine, front and rear differentials, transfer cases, transmissions, shock absorbers and the bottom of the car. These parts that are relatively vulnerable to damage during the race are equipped with special high-strength protective plates to prevent these relatively fragile parts from being injured by the sand and gravel carried by the front wheels at high speeds.

The four tires of the car are also fitted with large, ultra-high-strength ground fenders. Zhang Lan naturally knew what this was for, this small device that didn't seem to have much effect was actually very necessary, of course. Its purpose is not to block muddy water, but to prevent the sand and gravel brought up by the car in front of it when driving at high speed to hit the car behind it. It's kind of a very human little thing.

As the car was left behind by Xiao Chenxi. Zhang Lan can take a closer look at the exterior of the car again: the door safety film has replaced the original glass windows, which is the usual practice in racing places, and the cars participating in the Dakar Rally are no exception. It has the advantage of reducing the damage caused to the rider by glass bursts. At the same time, the weight of the vehicle can be further reduced.

Of course, as with all race cars, in order to ensure that the engine power is used where it should be used most, and to reduce the weight of the car as much as possible, this car is not equipped with air conditioning, and the driver in the car can pull the safety film on the door a little more to cool down. Let the natural breeze blow inside. There is no other way.

Service tools and basic repair kits, special jacks, desert boards are all essential for Dakar racing cars, and they are securely fastened to the car. Otherwise, it can be very dangerous for the driver and navigator in the event of an accidental rollover. Don't shout "I'm never going to roll over!" Even the eight-time Dakar Rally winner Peter Hansel, who is a future winner of the Dakar Rally, is inevitably a rollover at the annual Dakar Rally, which is a completely normal accident in this event.

The same. The LED high-mounted brake lights on the roof above the rear of the car are also very important, especially for the small four-wheel drive car in the Dakar, if the car is unfortunately stuck on the downhill slope, the high-mounted LED brake lights can make it easier for the car behind to see, so as to avoid the detour, otherwise it will be a tragedy of car destruction and death.

"How do you do it in terms of body weights?" Looking at the engine that has obviously stepped back a lot, the center console that has obviously lengthened a lot, and the front and passenger seats that have obviously moved back a lot, Zhang Lan was a little puzzled, "For a full-time four-wheel drive model like ours, in such a tense competition, the distribution of body weight between the front and rear axles is generally 5:5 ratio is the most appropriate, such a design is most conducive to handling, and it is easier to keep the four wheels on the ground after jumping at high speed, rather than the front wheels landing first like those models with the engine front." , so that the car can rush out at the first time, reducing the time delayed by the car bounce. At the same time, it can greatly reduce the chance of damage to the girder, suspension and steering rod caused by the huge impact force when landing. But our engine is front-mounted, which seems to be very difficult to do, but looking at the way it looks now, do you move the engine and gearbox between the front and rear axles of the car? ”

"You can see that?" Xiao Chenxi seemed to be a little girl who had discovered her little secret, and spit out her little pink tongue embarrassedly, "That's right, now this car is no longer a front-mounted four-wheel drive off-road vehicle, although it looks like a front-mounted four-wheel drive racing car, but in fact this is a mid-mounted four-wheel drive off-road vehicle, indeed, the engine and gearbox of this racing car were moved by us to the front and rear axles of the car." \\\\\\”

Zhang Lan was finally completely speechless, wanting to correct this kind of design that is innately present and not a defect, as if only a very small number of top car modification studios can do it, and after the improvement of the car, the space of the driver and the co-pilot is also extremely narrow, but I didn't expect that the problem that all car modification engineers have a headache was solved so easily by the two little girls, not only successfully moved the engine and gearbox of the front-end four-wheel drive model to the front and rear axles of the car, The result is a mid-mounted 4WD car that is more suitable for off-roading, and the usable space for the driver and navigator of the car is not significantly reduced! ,

I wonder if the top car modification design factories abroad that pride themselves on being able to change the engine layout will cry or laugh when they hear the news? Or is it shameful and self-conscious?

"Finally, to make a summary," Xiao Chenxi finally concluded, "except for the appearance of this car is a bit like a snow leopard 3.6 off-road vehicle, other aspects almost have nothing to do with it." ”

Zhang Lan didn't have the slightest doubt about this.

"The design work is all done for you," Zhang Lan couldn't help but smile bitterly, "What is Brother Zhu doing?" Originally, it was planned to let Brother Zhu design the whole vehicle, but now that it's like this, is there anything else about Brother Zhu?

"These designs were originally completed by us and Brother Zhuzi!" Xiao Chenxi's beautiful eyes widened, as if she had seen something most incredible, and said, "Don't you know? ”

Sweat! How would I know if you don't say so? The black line in Zhang Lan's head: You can communicate through wireless data exchange, and I don't have the ability to do this.

"Oh," as soon as she finished saying this, Xiao Chenxi also understood the reason for this, and couldn't help but cover her mouth and laugh, "I forgot." Probably you think that this commentary should be carried out by Brother Zhuzi, right? Of course, Brother Zhuzi can actually be projected, but if, well, let Brother Zhuzi project, I'm afraid you need to find a bigger place and no one to do it. ”

Zhang Lan nodded, he forgot about this, he always remembered that Brother Zhu Zi had the ability of 3D stereoscopic projection, so he thought that the final design work would be handed over to Brother Zhu to do, and the things he explained to himself would also be carried out by Brother Zhuzi, but he forgot that if Brother Zhu wanted to project himself, he needed to turn himself into a humanoid state. Let Brother Pillar become a humanoid state? Sweat! At the very least, I have to find a barren mountain and wilderness with no one at night to proceed.

In order to watch a projection, I ran to the barren mountains and mountains in the middle of the night? The black line on Zhang Lan's head: In comparison, how can Xiao Chenxi be so happy with the projection?

"In addition to what we and Brother Zhu are doing now, some high-strength materials for engine and body modification need to be designed by Brother Zhu. Now Brother Zhu is working on these things, whether this car can be finally formed depends on Brother Zhuzi's design of these materials. Xiao Chenxi added.

"Oh," Zhang Lan nodded, "Have you chosen the logistics support vehicle for the convoy?" ”

There are two types of large trucks in the Dakar race: one is the logistics vehicle, the so-called T5 transporter, which travels on a route other than the track and can only meet the cars at the designated location of the race. The other is the racing cars, some of which are not only actually participating, but also some of them are directly supporting the small car groups of the same team.

Due to the different routes, regular logistics vehicles can only meet the cars at night, and if the cars are stuck in the desert or have damaged parts, they can only rely on their own race trucks to help. It is common practice for a strong team to choose to compete in both the truck and car categories, and then let their big car support their own small car when necessary.
