Chapter 266

In fact, many high-end models have the function of chassis height adjustment, through the independent air suspension system for height adjustment.

But their rise and fall range is very limited, mostly between 5 and 15 cm, and the effect is not too obvious, so in practice, the practicability is not great, more just a gimmick.

Chen Mo's design of this lifting device is not the case. The suspension system of this bulletproof off-road vehicle is originally a multi link independent suspension, and the design freedom of this suspension is very large.

Through the constraint angle design of connecting motion points, the suspension can actively adjust the wheel alignment when it is compressed, and can fully match and adjust the vehicle model, so as to maximize the tire grip and improve the control limit of the vehicle.

Moreover, when driving, it can effectively control the camber angle of the wheel, and has excellent performance in comfort and handling. Moreover, it has great adjustment space and modification possibility.

This provides a great convenience for Chen Mo's improvement. Chen Mo combines the suspension system and deformation system of bat chariot to improve this set of multi link independent suspension, which not only ensures sufficient strength and stability, but also enhances the adjustment range of wheels, and directly combines the independent chassis lifting system and independent suspension system of other models.

Through ingenious design, the structure of the upgraded independent suspension system is not particularly complex. While it has strong shock absorption and buffer, wheel adjustment and chassis lifting functions, the simple structure also makes the system strong in strength, stability and reliability.

The height adjustment range of the four tires is much larger than that of other high-end models with height adjustment function, and the role they can play will be incomparable.

Through the adjustment of the wheel position, the minimum chassis height can be reduced to 10 cm, ensuring the maximum stability, giving play to a higher speed, and the maximum can be increased to 50 cm, which is higher than the chassis height of general military off-road vehicles and armored vehicles. Only a few specially modified extreme off-road vehicles can be comparable with it. The off-road performance is extremely strong, and all kinds of complex ground Shape and obstacles can be easily crossed, and the trafficability is extremely strong.

In addition to the great changes made to the suspension system, there are also some changes in other systems, but the extent is not large. Chen Mo has been modified in the main part. Each team of the R & D and design department only needs to make minor adjustments according to Chen Mo's modification, and refine some parts. The overall change range is not large, the workload is not much, and no cost is required Too long.

Chen Mo asks them to finish it in three days. It seems that the time is very tense. But Chen Mo knows that the difficulty is not big, but it will be very busy.

Chen Mo's preliminary revised design drawings were sent to the R & D and design department, and they quickly adjusted the relevant details according to Chen Mo's modification, including the size of parts, specifications and models of parts, etc.

The modification of the specific suspension system, parts and other parts is completed by each corresponding group of the R & D department, while the design department mainly responsible for the body shape, interior and exterior decoration and other parts has also received a modification drawing from Chen mura.

In fact, if a car is divided into simple parts, it can be directly divided into body and chassis.

The most critical core part of the whole car, the main functional systems are all on the chassis, including engine, clutch, steering wheel, fuel tank and other transmission, driving, steering, braking and electrical control systems.

In fact, even if there is no car body, the assembled chassis can actually run normally. In the test link of automobile production, you can often see a car site without car body shell, which is driven by testers, just like a full convertible car in the test field.

If the chassis part is the body of the car and the core of the running operation of the car, then the body shell is like its clothes and armor, playing a role of beauty and protection.

Although you can drive naked, you must be comfortable and safe without wearing clothes and armor.

The body of the bulletproof car is more like heavy armor, which provides more powerful protection for the engine system and the passengers in the car.

However, the drawings Chen Mo sent to the design department stripped the critical heavy armor down!

On the drawings, Chen Mo did not change the original body frame, but cancelled all the body armor, ceramics, special alloy and bulletproof composite materials that play a role in bulletproof. Only bulletproof glass was retained, and the whole body shell was replaced with 3mm thick steel plate.

Although the thickness of 0.8-1.2mm is much higher than that of ordinary models, it is also absolutely inferior to the original bullet proof armor, not to mention the built-in ceramic, special alloy and other bullet proof materials.

It's impossible to expect such a layer of 3mm thick steel plate to play a strong bulletproof role. At most, it's just a little stronger than ordinary cross-country vehicles and can withstand the shooting of small caliber pistols. It's absolutely impossible to withstand the shooting of large caliber pistols and rifles, let alone hand grenades and bombs. This kind of defensive performance is not a bulletproof vehicle at all Now.

Is their new boss going to change his previous position and stop working on bulletproof cars?It's not impossible. After the boss's improved new engine was manufactured and installed on the sample car, many of them went to the test field to watch the test curiously. They still remember the powerful power. If the heavy bullet proof armor is cancelled and replaced by the ordinary shell with a thickness of 3mm, the weight of the car body will be The quantity will be reduced a lot, the performance of this off-road vehicle will be more powerful, and it is not impossible for the acceleration ability to surpass the sports car.

Strong off-road ability and super acceleration performance and limit speed at the same time, maybe more popular than bulletproof car.

However, if the boss really intends to do this, why should he keep the 3mm thick body steel plate? Is it OK to directly use the conventional steel plate with a thickness of 1mm or even 0.8mm? The weight of the steel plate is three or four hundred kilograms. If we pursue speed, it will have a great impact.

Such a layer of steel plate can only resist small caliber pistols. Even if you want to continue playing bulletproof stunt, it has no great effect at all. It is impossible to give consideration to all three. It's better to abandon the concept of bulletproof and focus on cross-country and speed.

Although they were puzzled, they quickly revised according to Chen Mo's drawings and requirements, which made their work easier.

Chen Mo is very satisfied with the shape of the body they designed, and has not made too much modification, so they just need to cancel the bulletproof armored structure, and then modify some parameters of the body. Referring to ordinary non bulletproof models, the modification speed is very fast, and it is completed on time in three days.

Three days later, the modification of the whole model is completely completed, the production line has been integrated and adjusted, and can be put into production at any time.

The original refitting workshop has also installed new smelting, forging, casting and processing equipment, which will serve as the engine production center and be responsible for the production of new engines.

However, the production of engine is not the whole work of this workshop, which can be seen from the layout of the workshop.

At the end of the huge workshop is a row of huge vacuum arc melting furnaces, which can smelt a variety of high melting point metals under vacuum conditions, usually used in the production of special alloys.

The engine block and piston are made of high-strength aluminum alloy, while the crankshaft is made of alloy steel. Tyler Motors has not mass produced the engine before. The aluminum alloy and alloy steel used by the engine research and development team are all the finished alloy materials purchased directly from the outside for remelting and processing. Therefore, they actually have no engine Formula of high strength aluminum alloy and alloy steel.

However, Chen Mo is hard to avoid. The technical reserve he brought from Hydra is quite comprehensive, and the formula of several kinds of engine alloys is not worth mentioning at all. In the row of vacuum arc melting furnaces arranged in order, two of them are specially used to produce engine aluminum alloy and crankshaft alloy steel.

All kinds of raw materials are added into the furnace according to a certain proportion for smelting. Under the vacuum environment, these metal raw materials are melted rapidly under the high temperature arc formed by the discharge between the electrodes, and various metal elements are integrated with each other.

After fully melting and combining, the liquid alloy is then injected into the pressed mold. After the belt is cooled gradually, the preliminarily cast cylinder block and crankshaft will enter the next process, and the CNC machine will carry out rough machining and finish machining.

This engine production line, which consists of many equipment, from the initial alloy smelting, casting, processing to final assembly, only occupies half of the space of this huge workshop. On the other side, it also starts from two vacuum arc melting furnaces, but contains more large-scale machinery production lines, producing steel plates of different shapes and sizes.

This is the production line of the body shell. The melted golden red metal liquid is directly pressed into a 3mm thick homogeneous steel plate by the rolling mill through several processes. After cutting, stamping, welding, assembly and other processes, it turns into a hard and smooth silver body shell, framework, ceiling, door, engine cover, trunk cover and other parts All parts are made of this steel plate.

However, this kind of steel plate is not an ordinary product. Otherwise, Chen Mo can use the purchased ready-made steel plate directly like other automobile companies. There is no need to smelt and produce the steel plate from scratch.

As the design department guessed, Chen Mo, after improving the engine, saw the potential of the car in speed, and planned to make the best of speed and acceleration performance.

But he didn't intend to give up the bulletproof function and pursue cross-country and speed, but intended to give consideration to cross-country, speed and bulletproof at the same time, fully stimulate the potential of the car, and enhance the competitiveness to the maximum.

There is no problem in off-road. To improve the speed and acceleration performance, it is necessary to reduce the weight of the car. It seems impossible for anyone to reduce the weight of the body while ensuring the bulletproof performance, but it is a simple thing for Chen.

Not to mention Dr. marklain's powerful performance, which is second only to the Edelman alloy, and does not need to vibrate gold, the alpha alloy can be made by using conventional materials. Chen Mo alone has a variety of formulas of high-strength special alloy from the scientific and technological materials brought by Hydra.After comparing several of the most powerful alloys in the world, Chen Mo chose this one from a large number of special alloys in the database.

Compared with the high-cost titanium alloy and other superalloys, this special alloy H-2 of Hydra has not only stronger defense ability and lighter weight, but also far lower cost than those superalloys. Although it also contains many expensive metals, its content is very small and the average cost is not high.

This layer of 3mm thick special alloy steel plate does not weigh much more than the shell of the ordinary car. Compared with the ordinary steel plate, the weight of the whole car weighs less than 100kg, which is equivalent to pulling one or two more people. It has little impact on the acceleration performance and ultimate speed of the car.

However, in terms of defense, it can be compared with the body armor with a total weight of more than one ton, or even more.

Although this special alloy steel plate is only 3mm thick, its strength is very high. Ordinary pistol bullets can't even leave too deep traces on it. The bullets of conventional automatic rifles can only make the steel plate slightly concave, but they can't penetrate at all. Even under continuous high-strength attack, it can guarantee a long-lasting strong defense.

Unlike ordinary bulletproof vehicles, if the same area is attacked repeatedly and the bulletproof armor or ceramic plate is broken, it can not guarantee the defense force, and it is easy to be broken by the attack behind, causing damage to the personnel in the vehicle.

Therefore, although there is little difference in the power of the strongest attack they can resist in data, in actual use, the actual performance of the H-2 special alloy steel plate is far more durable than the bulky multi-layer bullet proof armor of ordinary bullet proof vehicles.

This is of great significance to the life safety of the passengers in the vehicle.

Because the purpose of bulletproof vehicle itself is to resist the attack in a certain period of time in case of emergency, to ensure the safety of people in the vehicle, and to quickly evacuate from the dangerous area.

From the time of being attacked to the time of successfully evacuating, the life and death of the people in the car will be determined!

If the attacker's firepower is very strong, there are high-speed and powerful weapons such as machine guns. Even if the armor of ordinary bulletproof vehicles can withstand the initial attack, it is likely to be broken under the subsequent continuous attack, and the time for evacuation and escape is very short.

With this layer of H-2 special alloy steel plate, the bulletproof SUV designed by Chen Mo can still last for a long time even under the continuous strafing of multiple automatic rifles or machine guns, providing more time and guarantee for safe evacuation.
