Chapter 243 Carriage Making (1)
I almost overlooked the problem. This might be the gap between me and a professional technician. After all, Ye Kai is not a professional manufacturing engineer.
The wheels are made of wood. Because they are vulnerable parts, they must be easy to manufacture and replace. Without Ye Kai, the construction would not be possible.
看着叶凯制作的车轮，三人都有些惊讶。一般来说，马车的车轮直径约为110～115米克（1.3～1.4米）左右。但他手上的车轮只有40米克（48厘米）左右。
“It’s so small. Is this really okay?”
"A smaller car is easier to drive and park, and easier to turn. Although the passability will be reduced, when driving on such bumpy terrain, the weight of the car will bounce off the rocks, right?"
“That’s probably it.”
Make two such wheels. Ye Kai installed the wheels on both sides of the metal axle through the bearings and assembled them into a sandwiched structure. In this way, a complete wheel was formed.
Ye Kai installed it around to support the box. It is a four-point independent suspension system. It is the same structure as a car.
In this world, this structure will become a rather unique shape. Ye Kai imagined the final form and thought about making new parts.
Ye Kai sometimes stopped to think while continuing to assemble. After all, although each part was made from existing mechanisms, the overall structure he conceived was his original creation.
He had to design a simple structure so that people other than himself could perform maintenance and simple repairs. Otherwise, he would not be able to set off happily.
The wheel is not like the usual multiple spokes extending from the hub, but a one-piece structure with only five spokes extending from the hub to the rim.
This structure is very strong, but there is almost no way for others to process it except the Transformer Magician. But Ye Kai is not worried about this. He plans to make a custom product that focuses on strength.
He wrapped the part that came into contact with the ground with hard and blade-resistant monster hide to prevent wear and tear.
Ye Kai clamped the bearing with a long metal plate with an arc in the middle, and then extended the axle from the top of the arc. This is not used to fix the wheel to the carriage frame, but to allow it to move up and down in the hole.
Air cushioning devices (air shock absorbers) are placed in front and behind this axle to absorb bumps and impacts from the road surface to the wheels.
Cylinder-type buffers can buffer changes in the axial direction, but are more vulnerable to lateral loads. Because the inside of the cylinder will be damaged. Therefore, the role of this axis is to prevent the horizontal load of the road surface. Cylindrical rollers are also embedded in the bearings of the frame to ensure smooth up and down movement.
In the design of the entire mechanism, reducing the size of the wheel is one of the most important reasons. If the wheel becomes larger, the supporting shaft must also become longer, so the structure will become loose. In this way, the strength will be greatly reduced.
On the contrary, the disadvantage of reducing the wheel size is only the reduced passability mentioned above. Reduced wheels mean that the buffer device is also shorter and the telescopic range is smaller.
“It’s really fun. It rolls easily but you don’t feel any vibration at all.”
"That's bad. Let Fino come on too."
The women sat on a base fixed to the frame and played a game of rolling the wheel.
"Hey, don't forget to make three more of the same kind."
"You're the one who built the car. Our magic is only of limited use."
"Yes, indeed."
It looks a bit lonely when it is placed aside. The mechanism around the wheel is quite heavy if made separately, but it seems to meet Klein's requirements.
----------------
After receiving Ye Kai's completion report, Klein couldn't wait to come to the palace training ground.
There, a frame 300 m (3.6 m) long and 170 m (about 2 m) wide, nearly three times larger than an ordinary carriage, was mounted on a floor. From the frame extended drawbars, conveniently tied together with purple and blue leather straps.
“Isn’t this huge?”
“Wouldn’t a larger cabin be more comfortable?”
"There must be a limit, right? If you put another box on this floor, it will be even heavier. Although I'm not an expert, it seems a bit difficult to pull all four horses up, right?"
"You think so? But they can pull this easily."
After they were promoted, the prince's family walked onto the floor. Eleanor also said "Excuse me" and went up with the help of Fran. Because there is a base under the wheels, the height of the floor is 80 meters (96 centimeters). Although scaffolding was prepared, it might also be a troublesome thing for women wearing skirts.
“Purple, Blue, please.”
As Ye Kai spoke, Senel Bird took a step forward. The carriage started smoothly without any resistance.
“How does it feel? Is it heavy?”
“Coo-coo!”
"Gulili!"
“Maybe it’s totally fine?”
"Goo!"
They moved forward at random, then turned back, and thus began a circle, but the Senel birds seemed to find it completely unburdened.
Even the prince's family, who were a little scared at first, were surprised to find that the car did not shake at all when they went over the grass and the bumps raised by the horses' hooves. Even Senna and Eleanor were able to stand without any support.
“Is this… magic?”
“No. It’s that structure.”
“Unbelievable. How could someone make something like this?”
“This is the crystallization of ancient wisdom.”
After returning to the original position, he asked Senelbird to stop and operated the brakes himself to stop the vehicle. This is a friction brake using a lever. Pulling the rope, the leather pad will press on the rear wheel, realizing the braking mechanism.
There are other details that are processed in greater depth.
Afterwards, Ye Kai stared at the wheel mechanism being tested sideways in the room, and the air pressure buffer device that he had planned to use was abandoned. He realized that if it was used directly outside, dirt and debris would enter the cylinder and damage the inside of the cylinder.
The improved cylinder is sealed except for the bottom and the hole through which the piston rod passes and the small air hole, and a gasket is installed on the hole. In this way, there is basically no problem of foreign matter entering the cylinder.
He also let Cham sit on it and roll over a small slope. After hearing a slight friction sound and vibration, Ye Kai reconsidered the layout of the cylinder.
As a result, he installed the cylinders in front and behind the shaft at a slight angle to the shaft. This would suppress the shaft's wobble. This attempt was successful and the wobble almost disappeared.
He found that he could not find the problem just by design drawings and ideas, and he had to assemble the test product to find it. This also proved that he was an amateur. It was precisely because of the magic of transformation that he could easily make corrections on the spot and make efficient items.
Afterwards, the adventurers also boarded the vehicle, added loads, and drove around the playground a few times, but everyone felt extremely comfortable. The Senelbird also felt almost no fatigue. Klein seemed very satisfied with the finished product.
