Datang: Investment Overlord Xiang Yu at the beginning

A quarter of an hour later, Li Ke, dressed in a military uniform, followed Lu Dashan, who was burly and tall in an earthen yellow robe, passed through the building complex of the main wing and came to the secret workshop in the back mountain.

The secret workshop was covered with a canvas-covered two-meter-high wooden fence enclosing an area with a circumference of more than 300 meters.

After walking into it, what caught Li Ke’s eyes was something that should definitely not appear in this era.

A three-story ironwood product shaped like a ship, painted earthy yellow.

In front of this woodwork is a nose shaped like a trailer of later generations, which of course is magnified many times.

At the rear is a car truck connected to the front of the car with an iron column bearing.

This is not out of the ordinary, the most out of line is the multiple small wheels underneath.

The front of the truck is eight wheels, two on one side, and behind the middle road of the truck, there are two sets of eight wheels.

These are small fifteen-inch wheels.

This fifteen-inch size is the same size as the cheap cars of later generations, such as Chery, Kaiyue and other wheels, which do not seem to match this huge body at all.

However, the dark circle on the wheel is a rubber tire!

The four sets of tires in the back, each side has two merged, which is the front four and the back eight

This is also specially shipped back by Li Kei from the tropics.

“King Yan, this tire is not good, I have tried my best to inflate and reduce the weight of the method you said, I really can’t figure it out, I can only dig it into a honeycomb shape and fill it with spring iron, which ensures a certain elasticity.”

Lu Dashan saw that Li Ke’s attention was all on the tires, and quickly explained.

“Very good, you couldn’t find King Ben to consult during the expedition, and actually came up with a compromise plan so quickly, not bad!”

Seeing that Lu Dashan actually thought of a honeycomb and then filled with springs to reduce weight and maintain elasticity, Li Kei nodded with satisfaction.

“These inspirations are all from the design of this shock-absorbing torsion beam that Yan Wang gave us, borrowing flowers to offer Buddha, and the villain also found that this shock-absorbing suspension, as well as rubber tires, can also be used on ordinary horse bodies, and it must be comfortable to ride!” Such a carriage will definitely sell well! ”

Lu Dashan seemed to see countless amounts of money rolling in.

“Hahaha, this is not urgent, since you can make rubber tires, Ben Wang continues to send more fleets to transport tires, when the time comes, you want to make this type of carriage, some materials are made for you, after making it, Ben Wang will give you a commission!”

Li Ji smiled and patted Lu Dashan’s shoulder, then found the stairs to board the car and climbed straight to the front of the car.

About six meters high, twelve meters long, and four meters wide, the front of the car is divided into three layers, each layer has three twisting discs that can be moved by war horses, each twisting disc can accommodate three war horses to provide power, the twisting disc turns, driving the gears behind the car, can make the rear wheel rotate.

These twist discs also have more than a dozen layers of pinions of different sizes underneath, similar to the shifting devices of later mountain bikes, which can be changed with a handlebar similar to a brake knife.

Adjusting different gear ratios can make the same effect as the pulley principle, when the most resisted, the gear ratio difference is the largest, and the war horse rotates a full five turns to drive the rear wheel to make a turn, so that the car can start slowly with the least force.

When adjusted to the highest gear, the warhorse wheel rotates once, and the wheel’s pinion can make the wheel rotate a full eight times to enter high-speed mode.

Not only that, the drive gear of the rear wheel also has a differential similar to a bicycle, that is, the wheels can continue to rotate when the millstone does not rotate, so that just like the foot does not board, the bicycle can continue to move forward, so that the speed will always be faster than the drive wheel.

In this way, this animal-powered truck can run at a speed of more than forty hours with fifteen tons, that is, one thousand stones of rice, which is no lower than that of a war horse.

Of course, the disadvantage is that you can’t reverse at any time, you can only go down to one person to reverse, block the differential gear of the driving wheel with a special iron rod, and then the war horse pulls the grinding in turn to achieve reversing.

In front of the third floor, there is a ship-like rudder, set on the left side of the wheelhouse, which is its steering wheel.

“This is the brake lever that King Ben said?”

Li Kei looked at the co-pilot’s position, which had three handles on it.

One handle is the clutch, which temporarily cuts off the power.

The other two levers are the front brake and the rear brake.

The brakes of this kind of car must be pulled to the clutch first, otherwise the grinding disc will suddenly be pulled to a stop, which may damage the war horse.

It is worth mentioning that the brakes of this car use brake discs, which are installed in the twelve wheels of the car.

“After the test, are you sure it works?” This steering wheel is still a bit heavy! ”

Li Kei hit the steering wheel curiously, and found that although the steering wheel has been made very large, it also has to rotate five turns very hard to hit the head, after all, there is no hydraulic pressure and no telex in this era, and can only use the pulley principle of distance for power, and set two more turns to ensure that people can turn the four wheels of the front of the car.

“It’s a bit heavy in place, you have to use all your strength to turn, it’s much easier to run, and if you set two more laps, the small steering is too inflexible, and the slight deviation is difficult to correct.”

Lu Dashan said a little embarrassed.

“Simply increase the gear of the steering wheel, the steering wheel can also be boldly added to one person height, just reduce the number of laps, reduce it to three and a half laps to the head, so that driving is easier, the helmsman does not have to be so tired, the chief and co-pilot set up a seat, and there is no need to stand.”

Li Kei knocked on the steering wheel whose diameter was already half a person high, said in a deep voice, and looked out of the car.

This primitive animal power truck is not easy to operate, but this view is really bull running, after all, this is the height of a three-story building.

Then the rearview mirror uses a polished copper mirror that is maddeningly blurred to avoid exposing the glass.

However, although the details are not clear, the situation behind can be seen approximately, so it is okay.

“Obey, King Yan! If you start work right away, you can add the seat you said and change the steering wheel gear by evening! ”

Lu Dashan said respectfully.

The space is large, and the structure is not complicated, which is similar to a ship-like truck that is particularly easy to repair, and it is quick to change anything without touching the suspension.

“Very good, you adjust it as soon as possible, and then the king of Ming Japan will release the news, let the whole Chang’an observe this thing, and also let the people of the world know that we are about to have such a transport weapon for sale!”

Li Kei patted Lu Dashan’s shoulder with satisfaction and gave the final adjustment task.

Next, this thing will completely change the Great Tang!
