The first car in the world was produced on 1886129 October, with a history of more than 200 years. Cars have been evolving with the changes of people's needs. It never occurred to Mr. Carl Benz that under his leadership, people all over the world could not do without automobile products. I believe that the future will only become more and more advanced and smarter. What great inventions in automobiles were developed by great human beings?
Body? ：
Active aerodynamic system;
Friends who like refitting must know that an excellent aerodynamic package is a necessary condition for the stability of vehicles when driving. The front nose wing and the rear tail wing can provide enough downward pressure to firmly press the front end of the vehicle on the ground, and at the same time guide the passing airflow to the designed direction to form positive pressure. The active aerodynamic system needs to be connected with the ECU of the vehicle to collect data in real time, so that the air kit of the vehicle body changes with the change of the vehicle's straight driving and turning state, so that the vehicle can maintain a good driving posture and super stability as much as possible.
Body material:
It is divided into a series of materials such as carbon fiber, glass fiber, iron, steel, aluminum, aluminum alloy, magnesium aluminum alloy and reinforced plastic. At present, the most advanced carbon fiber body has good strength and heat resistance, and greatly reduces the weight of the vehicle. The world's most famous Formula One Championship (FIA? Formula? 1? The world? All the cars in the championship are made of carbon fiber body and carbon fiber.
Rear view mirror:
The original form was realized by employing people. Two people sit back to back. The person sitting in the front is responsible for driving, and the person sitting in the back is responsible for observing the situation in the rear and telling the driver. The earliest application of vehicle rearview mirror is 1905, which simply fixes a piece of glass to observe the rear. Today, no matter how many kinds of grotesque rearview mirrors or electronic rearview mirrors are introduced by manufacturers, their basic purpose has not changed. Can you imagine driving a car without rearview mirrors?
Chassis:
Active suspension system:
At present, most cars use passive suspension, that is, only tires will react when they hit obstacles. Because of its simple structure, low cost and high popularization rate. In other words, the suspension that can be adjusted before the wheels contact or according to the driving posture of the car body is called active suspension system. Mercedes-Benz's magic body technology, Audi's magic body chassis and BMW's power chassis all belong to the category of active suspension system, which can not only achieve excellent comfort performance, but also achieve safety effect by instantly improving the chassis height.
Rubber tires:
Everyone knows that cars evolved from horse-drawn carriages, which all use wooden tires. Later, people put the internal combustion engine on the carriage and became the first car in the world. Due to the improvement of power, wooden tires can not meet the performance of vehicles, so people try to fix rubber on the edge of wood to reduce bumps. So far, people have improved the characteristics of rubber countless times, but its main component is natural rubber. Hot-melt tire used in F 1 racing car is one of the improved works of rubber tire, which is very popular in major competitions because of its unparalleled grip on the ground, but it has not been popularized because of its short service life and high price. A set (four sets) of F 1 special tires can reach an average of 4,000 euros, but the service time is less than.
Disc brake:
If we can't stop, everything will be in vain. A good braking system is a necessary condition for prolonging service life. In 1950s, British brands Jaguar and Deng Lupu jointly developed the aircraft disc brake system. Later, Jaguar C won the Le Mans 24 Hours Rally with a disc brake. Now, disc brakes are the standard configuration of most ordinary family cars.
Gear drive:
Around 300 BC, humans first figured out the principle of gears. This circular part made of metal is meshed by teeth distributed around it, which lays a solid foundation for the development of power transmission technology later. Today, the gear structure is still the world's top power transmission form, and the gear has become lighter, more efficient and more durable through smooth technology and material changes. After the application of gears, Mr. Renault, the founder of French Renault Automobile Company, invented the differential in 1937.
Engine:
The most handsome car keys in the world. Do you know what this is? I think it's a big iron bar to liberate cars. Do you know what this car key is shaking? It's shaking the crankshaft. All the stroke engines in the world are realized by the reciprocating linear motion of the piston. According to the arrangement form, stroke engines can be divided into: in-line, V-shaped, W-shaped, horizontally opposed, triangular and so on. No matter how many arrangements there are, the ultimate goal is to make the crankshaft rotate like a liberated car. Of course, in addition to the stroke engine, there is also a controversial rotary engine. What, it was invented by a German fascist? Figas Wankel developed the world's first rotary engine in 1924-1954, because during World War II, Wankel was recruited by the German Air Force. It was not until 1967 that Mazda installed a rotary engine on its own car for the first time and purchased this technology from Wankel Company.
1862, the world-famous four-stroke engine principle is established. 1876 The Germans successfully manufactured the first reciprocating piston, single cylinder, horizontal, 3.2 kW (4.4 HP) four-stroke internal combustion engine. Back to today, the four-stroke engine is still the most installed in the car, and Mazda is still tirelessly improving its rotor engine. With the emergence of electric vehicles, engines will be gradually replaced in the near future. Can electric energy last as long as an internal combustion engine? Let time answer this question.
Engine supercharger:
According to technology, it can be divided into turbocharging and mechanical supercharging. The first car with turbocharger was a Chevrolet model of 196 1 year general motors. Mechanical supercharging was invented by German Benz in 1900. Because of the different pressurization forms, it is purchased by many manufacturers and used in different models. Interestingly, no matter what kind of supercharger is used, the engine technology is forcibly changed and the air intake is increased. Almost all the original technologies, such as ignition system, fuel injection, engine speed, air-fuel ratio, high-temperature resistant materials, engine oil index, fuel index, exhaust system, etc., should be improved accordingly, so the decades after people accepted supercharger are the fastest decades for engine technology improvement.
Electrical equipment:
DAS:
A few days ago, Mercedes released the W 1 1 racing car for the 2020 season. In addition to the brand-new appearance, there is also a latest technology DAS, which is realized by the expansion and contraction of the steering wheel, which will provide better cornering settings and reduce the resistance of straight sections. The results show that Mercedes-Benz's W 1 1 car is indeed the fastest in the lap test. In the following days, FIA announced that DAS technology would be banned in 20021season.
Seat belts and airbags:
1959 Volvo invented the three-point seat belt. 1980, Mercedes-Benz equipped airbags on S-class cars at that time, becoming the first car company in the world to use airbags as standard. I don't need to say more about these two technologies.
Sensor:
199 1? Artie? Released the industry first? High g? MEMS？ The device is mainly used for automobile airbag collision monitoring. How many in the world today? 35000? There are more than three kinds of sensors, of which hundreds are most commonly used in automobiles. It can be said that the advent of sensors is the greatest invention in the field of automobile development.
Driverless technology:
It is divided into L 1, L2, L3 and L4 according to the grade, and L4 is the ultimate grade. A car can always be responsible for driving safety without the intervention of the driver. Currently undergoing L3-level research and development. With the continuous development of science and technology, it is inevitable that the ultimate driverless car will come into our lives.
Write at the end:
The great inventions applied to automobiles are far more than these. If all of them are written, it is estimated that more than 10 will be serialized. Welcome your favorite friends to continue to communicate in the comments section below. I wish you all a happy mood during the epidemic!
