These car inventions, once regarded as a laughing stock, were later found to be very powerful technologies!

There are many things in the world. When it first appeared, people didn't recognize it, even said it was a joke, and it became people's entertainment after dinner. But later, I found out that this thing is really powerful, and it will even change people's lives. The same is true of cars. Many designs were regarded as a laughing stock at first, but later it was found that such designs were really powerful and even changed the development path of automobiles. In its own development process, the automobile has made numerous landmark inventions. At the initial stage of invention and application, every new technology will not be accepted by people because of immaturity, high failure rate, non-compliance with usage habits and other factors. However, with the development of science and technology, new technologies are becoming more and more mature. In the later application process, people will find the benefits of new technology more and more, gradually from resistance to acceptance to love, and finally can not do without it. Let's talk about a few inventions that were once regarded as a laughing stock in cars and later found to be really powerful. In fact, cars have been regarded as a laughing stock since the day they were born. At that time, the world was ruled by wagons. After the first car was invented, it was noisy and had a high failure rate. The road often breaks down, not pulling people, but pushing people. Laughed at by the world, he asserted that he was another "Fulton fool" and would not live for a few days. However, with the development of society, except for tourist attractions, carriages in other places are extinct, and cars have really become the masters of the world. 1, pneumatic tire: At the beginning of automobile invention, all the wheels used were made of wood or iron, and later they were covered with rubber. This kind of wheel has very poor vibration reduction effect, and the comfort of the car is very poor, so it is impossible to travel quickly. In 1980s, John Dunlop made a rubber hollow tire, and then Thomas made a rubber hollow tire with a valve switch, and pneumatic tire was born. However, due to the limited technical level at that time, this kind of tire often burst, leaked air, was not wear-resistant, was not accepted by people, and even once became a laughing stock. However, with the progress of technology and the unremitting pursuit of autobots, the pneumatic tire technology is becoming more and more perfect and eventually becomes one of the greatest inventions of automobiles. It can be said that if there were no pneumatic tires, the car would not have developed to this extent today. 2. Front drive structure: Early cars were basically driven by rear wheels, which seems to have become the standard structure of cars. Since 1970s, a small number of passenger cars have adopted the structure of front-engine and front-wheel drive. This is an unprecedented pioneering work, which was deeply criticized at that time, and even some car owners directly suppressed it and trumpeted the shortcomings of front-wheel drive, which once made the development of front-wheel drive difficult. However, with the development of society, people are more and more aware of the benefits of front-wheel drive, which is accepted by more and more people and gradually becomes the mainstream structure type of passenger cars. At present, more than 90% of passenger cars on the market are front drive structures, and even some luxury cars with rear drive have begun to use front drive structures. This seems to have come true: practice is the only criterion for testing truth! 3. Foldable energy-absorbing body structure: I believe that until today, many people can't accept the view of "foldable energy-absorbing". In the junior high school of automobile development, people thought that the stronger the automobile shell, the safer the automobile, so people made the automobile shell extremely hard. However, in the actual car collision accident, it is found that sometimes the car is not damaged, but the people in the car are injured, which runs counter to the fundamental purpose of car safety. It was not until the sixties and seventies of last century that automobile engineers began to study the energy absorption technology of automobile collapse and applied it to automobiles. However, when such a car actually collided, it looked very tragic and the parts were seriously damaged. If you don't look at the people in the car, people think it's even worse. If you don't accept it, it's a joke. However, with the development of automobile technology and culture, people increasingly realize that the essence of automobile safety is to protect people, and the damage of automobiles is secondary. The collapsed energy-absorbing body structure is the best in protecting the occupants in the car. Now almost all cars have this kind of collapsed energy-absorbing body structure. Anyone who says "the harder the body, the safer it is" will be laughed at. 4. Plastic bumper: A friend of mine didn't know that the bumper of the original car was plastic until he rear-ended a Mercedes-Benz one day, and the bumper of the luxury car was also plastic! For him, this is to destroy the existence of the three views. In his original idea, the car bumper should be made of steel and extremely hard, so as to play the role of insurance. But the fact tells him that the so-called bumper is a thin plastic shell! He was depressed for several days. In fact, the application of plastic bumper began in the 1980s, and it is a supporting product of collapsible energy-absorbing body structure, the main purpose of which is to reduce the harm of automobiles to pedestrians. But for a long time, people can't accept this change. They think that replacing steel bumper with plastic bumper is a simple decoration, which reduces the cost and is not good for automobile safety. With the passage of time, automobile safety regulations have become more and more standardized, and the advantages of plastic bumpers have gradually become prominent. People finally accepted this fact and found that this change greatly reduced the casualty rate of pedestrians, which was really good. In fact, there are many similar technologies in the development of automobiles, such as electronically controlled engines, automatic gearboxes, active suspension systems and differentials. Can be said to be an invention that changed the history of automobile development. Many jokes have become truth. This is the power of technology.
