There are new factories and supporting production in Fenggu Industrial Zone, and new cities are not idle either.

The Locomotive General Factory and Xincheng Heavy Industry received a task a few months ago to build cars.

It's not a motorcycle, it's a car running on land.

The above will not let them go through a hundred years of development in one go, and the car they are going to build this time is still within their ability.

Steamed cars and electric cars.

The steam of a car is the steam of steam, and it is also the only vehicle that can be called popular before the emergence of fuel vehicles.

Electric vehicles based on lead-acid batteries also appeared earlier than fuel vehicles. Due to the limitations of road conditions and battery life, they are mainly used for urban mobile phones, so they are not popular and are just a flash in the pan.

Among the two types of cars, the focus is on steaming cars. The exploration of electric cars is mainly to pave the way for the power grid system.

With the experience of producing steam locomotives, the research and development of steam trucks should not be difficult, but the tasks assigned above are relatively high, and the carrying capacity must reach three tons, which is a bit of a barely for road steam trucks.

Benz, who is now the deputy director of the Locomotive General Factory, led people to do some experiments on heavy-duty railway locomotives, and formed two teams to tackle steam cars and electric cars.

After several rounds of experiments, it was confirmed that steam cars cannot grow like steam locomotives.

It seems nonsense, but it is very important because people are easily influenced by experience and habits and may go to a dead end.

Even if the driver cannot see the front of the railway, he will probably smash the person. The railway-specific track form determines that no one will deliberately run up except intellectual disabilities and those who are dying.

There are also pedestrians, vans and trolleys on the road, like steam locomotives, which are a large lump in front. Although it can provide sufficient power, the driver cannot see the people in front of him, and he will die if he presses them all the way. The driver may have been beaten up for several rounds of revenge.

So, when maintaining a certain amount of power, make the cylinder small.

Fortunately, I have accumulated a lot of special experience when building a steam locomotive. The team knew that the cylinder should be small and maintained with sufficient power. It is best to use seamless hot-rolled cylinder blocks.

Welding... Even though there are oxygen in high-pressure gas cylinders recently, the strength of acetylene welding is still far from seamless forging technology.

The seamless hot-rolled cylinder block can withstand outrageous air pressure.

The steam locomotives running on railways now have a standard speed operating steam pressure of less than one megapas. Oh, ordinary citizens have not learned this unit yet, but it doesn’t matter. Pressure vessel factories and locomotive factories, as long as people in heavy industry can understand it. One megapa is ten kilograms per square centimeter.

In contrast, the high-pressure cylinder made by a three-axis hot rolling mill specially tailored for the pressure vessel factory by Xincheng Heavy Industry, the effective pressure has been measured to be 12 megapas. Due to the equipment capacity, it cannot be added up any further. The pressure vessel factory is trying to charge it and explode or until it is cracked to determine the highest pressure value.

This means that using seamless technology to produce the pressure cylinders of steam cars, even if the diameter is larger, it will definitely be fine to withstand a pressure of three to five megapas. However, this pressure is more dangerous to the driver. If you control it to 2 to 2.5 megapas, and relatively reduce the thickness of the cylinder wall, you can get about 80 horsepower with a weight of half a ton.

After the horsepower is powered in Fenggu, the calculation of the electric power is directly used without reference to the camel beast. One horse has a output capacity of one kilowatts, which is simple and easy to understand without conversion.

The steam mechanism, plus coal-fired, water tank storage, backup water, driving mechanism, transmission mechanism, covers a shell, including the wheels, the weight will probably exceed two tons, and three tons of goods will be added. In this way, the frame and wheels also need sufficient strength and increase weight.

The full load is more than six tons. The team members have calculated that will the 80 horsepower be smaller?

This has to be decided by the deputy factory manager.

Adding more water and water to more noodles is definitely not possible, there must be a trade-off.

"Our purpose is to replace ox carts. Does ox carts have speed? So we don't have to pursue the speed of the railway, just a little faster than ox carts."

The horsepower is not enough, and the torque is enough. Even 20 horsepower can drag a guy with six tons. 80 horsepower is enough to deal with some troublesome road conditions.

After determining the horsepower, the rest does not have a threshold for senior technicians who have built steam locomotives. Next, there is only one problem left - wheels.

If the time was pushed to two years ago, the wheels were not a problem. At that time, it was mainly gravel roads, so you could just put a steel wheel on it and press it over.

However, many road surfaces are hardened with cement now, and the road surface can't stand it with steel wheels, and the friction is not enough.

There is now a need for a material that can provide friction and assist in buffering and protecting the road surface.

Leather is good, but it is too expensive to use for wheels. This thing needs to achieve enough cushioning. It is not enough to be finished if it is forty or fifty layers. Moreover, leather can easily rot if it passes through muddy roads.

The steaming car team was looking for materials suitable for tires in the next two months.

There are many alternatives, but many of them cannot be mass-produced.

After two months, only two forms of tires barely meet the requirements.

This tire is a steel wheel hub with a cork press-fit tire, a special resin layer is added on the outside, and there are several paint brushing and final painter in the middle.

It can be used, but there are problems with durability. The group replaced the handmade tires and added the model car to a state of 20% overweight. After observing it at rest for about three days, it produced permanent deformation that could be measured with a ruler.

Fortunately, this kind of tire is not expensive, making the tire wider and reducing the pressure can also resist deformation. It is at least easier than feeding the cattle again and again. If there is no better one in the future, you can only choose one from it and the steel core tire.

The steel core tire is even more outrageous. This was a sudden thought by someone in the steam car group. He directly used elastic yellow steel to make the wheel hub. There was only a layer of resin that protected the wheel hub from being directly grounded on the outside, or a wear-resistant tarp cloth soaked in oil.

Everyone originally thought it was unrestrained, but when they went to the iron factory to consult, they said they could do it.

This kind of tire has better mass production capacity, but it also has a big drawback, which is that its performance difference will become particularly large under no load and full load, because the yellow plate can only be used according to the requirements of the maximum load overseas road conditions. In this way, the tire will feel the same as the pure steel tire when it is no load, and it will be hard.

The team comes back to calculate, and read a book. It’s okay. You can overcome the problem by putting some effort into the suspension of the frame and avoiding the steam mechanism being malfunctioned by external vibrations.

Both tires have different problems, but they can be used.

Benz made the decision to build two prototypes first, each with one tire and a different frame suspension, and lend them to other factories for use. Anyway, there is no time limit for the task, as long as you ensure that all companies are willing to buy it after mass production.

Compared with the smooth flow of the steam unit, the electric vehicle unit is more troublesome.

They had nothing to do in the past few months and helped other companies go.

There are many troubles in the internal and external components of lead-acid batteries. Fenggu Power has been working for a long time but has not made satisfactory and safer products.

Fenggu Electric Power, a company, was separated from the Redstone Magic Equipment Factory because of insufficient motor production capacity. It is also the motor provider for electric vehicle projects. It has more trouble here and will not build small motors at all. Xincheng Heavy Industry also needs people to help them find solutions.
