Rebirth of the 1980s: The Military Industry Empire

"Our precision machining capabilities are still lacking." Speaking of this, everyone sighed again.

In tank suspensions, torsion bar suspension is the most commonly used. After all, it is relatively simple, saves space, and can withstand large torques. However, it also has many shortcomings, such as the inability to adjust according to the terrain.

The most advanced suspension is hydropneumatic suspension. Each suspension can be adjusted automatically. When facing some special situations, such as when a depression angle is needed, the vehicle body can be lowered, relying on the hydropneumatic suspension to reduce the depression angle. This is the advanced performance of this suspension. At the same time, this suspension can also improve comfort and is the most promising suspension.

At this time, hearing Old Zhu's words, Qin Yang nodded: "That's right, these are just prototypes now, and imported parts are being purchased. In the future, these parts will definitely need to be produced independently."

That was enough. If Qin Yang said it could be produced independently, then it definitely could be.

"Unload the vehicle. Let's take a look at the technology of this vehicle. The lateral transmission you developed is the essence of this type of vehicle."

Common armored vehicles use central transmission. The vehicle has a drive shaft running from front to back in the center, connected to each axle, and each axle then transmits power to the wheels on both sides, completing the power transmission path.

This is the simplest, just like a heavy truck, and can be easily modified. However, the disadvantage of this is also quite obvious: there is a large bulge in the center!

This large bulge will greatly reduce the vehicle's ability to pass over obstacles. Even for heavy trucks, this bulge may collide with the ground when entering construction sites or rugged mountain roads.

Therefore, wheel hub reduction gears have been developed. Because the wheel hub reduction gear performs a reduction, the size of the central bevel gear can be reduced accordingly, greatly increasing the ground clearance compared to the large bulge in the center, and increasing the ability to pass over obstacles.

However, the bulge can only be reduced, not eliminated. It is impossible to make the bulge level with the bottom plate of the vehicle.

All centrally driven armored vehicles have this defect. If you want to change it, you have to use lateral transmission!

This is a method that everyone has never seen before. If Qin Yang hadn't proposed it, everyone wouldn't have dared to think about it. Now, this lateral transmission has appeared in front of everyone.

The engine and gearbox are still in place. After the power comes out of the gearbox, it is distributed to both sides, then forward and backward. This way, even if there are protrusions, they are on both sides of the vehicle body.

The chassis is like this now. After the chassis was unloaded, everyone's eyes turned to the chassis, looking at the protrusions on the inside of the wheels.

This protrusion is completely above the floor and is also on the edge. This place will be used to place seats in the future, which will not bring any impact on the internal layout.

Everyone was sighing as they looked at this layout.

"There is nothing that cannot be done, only things that cannot be imagined. The layout provided by President Qin is the best solution." Everyone marveled.

"Yes, this solution is very interesting, but how to solve the problem of wheel slip on each axle in this power transmission path?"

In the central transmission system, there is a special differential lock. In the mouths of hardcore off-road vehicle players, the so-called 'number of locks' is something that countless people talk about with relish. In the field of trucks, the differential lock is just a common thing. Without a differential lock, it is very difficult to get out of trouble, but with this thing, it is easy.

Wheeled military vehicles have this thing even more. In fact, it is very simple, just locking the differential. Everyone is familiar with this, but how to lock each wheel in this lateral transmission system? When encountering a place where you need to get out of trouble, it won't work without a lock, and even in normal driving, the differential function is indispensable!

The differential is a great invention. It solves the problem of the different driving distances on both sides of the car during driving. On a straight road, the distance traveled by the wheels on both sides is the same, but on a curved road, the distance traveled by the wheels on both sides is different. If the wheels on both sides are directly connected by one axle, then it will not be able to move.

At this time, a differential is needed. Both sides are two half-axles, with differential gears connected in the middle. The design of this thing is very ingenious. Four bevel gears form a whole, which can transmit the same power left and right, and can also reduce the power output after one side encounters resistance, allowing the other side to obtain sufficient power.

This is necessary when steering, but it is counterproductive when getting out of trouble. The specific manifestation is that one tire that is normally in contact with the ground will not turn, while the other tire that is stuck in the mud is spinning wildly, and all the power is wasted. At this time, a differential lock is needed.

Conventional vehicles are like this, so what about the current lateral transmission? How does its differential system work?

"As an infantry fighting vehicle, it must meet basic needs. Our drive shaft can perform differential and locking on each wheel," Wang Jinman introduced: "At the same time, our system can also switch power as needed. For example, when driving on the highway, our front two axles can switch off the power, leaving only the rear two axles, which can also save fuel."

The specific principle is not convenient to say for the time being, but the effect can still be said. Various requirements have been achieved, especially the ability to cut off power!

All-wheel drive vehicles use more fuel than two-wheel drive vehicles because of the resistance of two more wheels. Therefore, many cars can switch between four-wheel drive and two-wheel drive. If you need power, you have power, and if you need to save fuel, you can save fuel. Our big eight-wheeler can also switch between eight-wheel drive and four-wheel drive.
