Chapter 139： Test drive: Isn't this an automatic transmission?

A group of people came to the garage and looked at the caravan with a length of eight meters and a width of two meters.

Look at the posture, it is no different from a normal car.

There is a steering wheel, a brake, a throttle, and of course no gearbox.

But it's like a flatbed truck, and it's an ultra-simple version.

"This car is actually similar to an automatic car... Go to the monitoring room, Kent and Philip, come out with me, and I will tell you how to drive."

An Kai slipped on his protective clothing, then opened the garage door and started the small caravan, relying on the power of the engine to slowly drive the car out.

After the garage door was closed, An Kai drove to the side of the shelter door. The area in front was simply leveled by him. Although the range was not large enough, it was enough to drive this small caravan. And just within the coverage of the camera, the people inside can watch the caravan when it is turned on through the screen.

An Kai sat directly in the cab, Kent sat next to him, and Philip sat on the iron shelf at the back.

An Kai starts the engine first. This step is exactly the same as that of a car.

Then put down the handbrake, the caravan began to move forward slowly. It's just very slow, just like a snail crawling.

It stands to reason that from the gate of the sanctuary, when the flat raid extends outward, the terrain is constantly getting lower.

This is also deliberately done by An Kai, so as to ensure that when it rains, the rain will not pour into the shelter. Although it has not rained outside since the nuclear explosion, I believe it is not the only thing that will rain. After all, the low temperature of nuclear winter can only last for a period of time, maybe a few months, but at most only a few years. After a few years, nuclear radiation will not disappear so quickly, but the radiation clouds in the sky will slowly dissipate and gradually become thinner. After the temperature rises, rainfall will naturally occur.

There may be acid rain and other phenomena at that time, so the protection of the shelter must be done well.

But if there is really rain, the radioactive dust in the air will be cleaned up a lot. Although the radioactive dust on the ground is still harmful, it is better than floating in the air.

Okay, far away...

Let's talk about the small caravan.

Because of its insufficient weight, even if the handbrake is raised, the speed of the car is very low.

An Kai slowly released the brakes, and the caravan began to advance at the engine speed.

So this small caravan is very similar to an automatic car.

This is the case with automatic transmission cars. The brake and clutch are integrated. When the brake is stepped on, the clutch is released, and when the brake is released, the clutch is closed. This is also the most convenient place for an automatic transmission car compared to a manual transmission car, because the original more complicated operation steps are simplified. The driver does not need to change gears back and forth during driving, and does not require frequent operations. Clutch, apply the brake only when the brake is needed. When you want to move forward, release the brake and the clutch automatically closes, and the car can move forward at a high speed, and then it can be directly supplied with oil.

The power caravan is also in this mode of operation, which can be said to be very simple.

It’s easy to start, so don’t worry about holding the car.

When the car speeds up slightly and reaches about ten kilometers per hour, it is located in the center of the cab, between the two seats. Air begins to pass, and the air extraction turbine inside begins to rotate, and as it rotates, the air extraction speed increases. Come sooner. The increase in the pumping speed resulted in an increase in the speed of the turbine. After a distance of more than 100 meters, Ankai directly shut down the engine.

At this time, the engine is no longer needed, and the exhaust turbine can already provide enough power.

Of course, the car is now empty, and the car itself is not too heavy. If it is full of cargo, it is estimated that the speed of the turbine can provide sufficient power when the caravan has to accelerate to 34 kilometers per hour.

But in any case, this fuel-saving, simple-structured car is still very useful for shelters that lack materials and fuel.

Then Kent and Philip tried it out in turn, and both felt that this car was very good. Especially Kent, he is a person who likes cars very much. The power caravan, an unprecedented vehicle, is really too attractive to him. If it hadn't been for An Kai to stop in time, I'm afraid this cargo would have to drive a small caravan out for a violent lap before it was finished.

If it is a peaceful year, An Kai will just go out and run. Or if the zombies are not so perverted, it doesn’t matter if Kent drives a small caravan out for a lap, but now there are super zombies outside. Although I don’t know if the other party knows the situation at the shelter, I can go out less for safety. It's best to go out less, as long as you go out more often, it will inevitably attract the other party's attention, and then it will be really troublesome.

drove the caravan back to the shelter. There are now three vehicles in the shelter.

are an off-road vehicle, a large truck, and a small caravan.

Off-road vehicles have the strongest passability, but their cargo capacity is very poor. It’s actually good to go out for road exploration and patrol.

The large truck has a very strong carrying capacity, but it is too dynamic and extremely fuel-intensive. To be honest, Ankai now doesn't need it if it can be used. After all, there is not much gasoline on Herto's side, and Herto also has survivors. In the past, it was enough to pull gasoline once. If you go there often, people will definitely not let them. In the future, everyone will have to trade The shelter now does not need gasoline in daily life. Only vehicles need gasoline, so if you can use less, use less.

The newly-appearing power caravan is the one with the least movement and the carrying capacity is also good, but the passability is relatively poor, and there is a risk of overturning when encountering a slightly bumpy ground. Who makes it too light? The advantage of self-importance is stability. Is the truck heavy? Heavy, so stable. Is the tank heavy? Heavier, so more stable.

The biggest problem of the small caravan is that it does not have enough weight.

But there is no way to change this problem.

Because it is a simple transportation tool derived from the theory of rotorcraft. If its own weight is too large, the suspension, load-bearing, steering, braking, power and other systems must be changed. Then the power mode of turbo suction will not be enough. The fuel engine must be used all the way. In this way...except for the absence of a shell, what is the difference from a car?

Without using a fuel engine, if the power is not enough, the car can't move.

So if you want the car to move easily, the weight should not be too high, so the car will easily roll over.

These are no alternatives. This requires Kent and Philip to control the caravan when they are out, and it is best to find a road that is stable enough.

Fortunately, they have been to Herto once before, and they already have a relatively mature route. After the subway is built, it will be safe to move it, at least there is no need to walk on the ground.
