The history of cars
History of automobile development-early period
Vehicles in ancient China
The first car in human history was invented by the ancestors of the Chinese nation. According to historical records, in the Dayu era in the early summer of more than 2000 BC, a man named Xi Zhong invented a car with two wheels to set up an axle. The axle is fixed on the frame with a shaft, and a suitcase is attached to the frame for loading goods. This is the first car in the world.
The original means of transportation were all human-driven, and they were called rickshaws. Later, people began to use cattle and horse-drawn carts, which were called animal-drawn carts. According to legend, the animal-drawn cart was invented by Shang Tang's ancestors Xiangtu and Wang Hai.
In the development of vehicles in past dynasties, the south guide car and the drum car in mind also have important technical value.
During the Three Kingdoms period, there was a skilled technician named Ma Jun who invented the compass. The South Guide Car is a kind of two-wheeled single-wheeled car, on which stands a Woodenhead, with his arm extended to the south. As long as you start driving, Woodenhead's arm always points to the south, no matter whether you turn east or west.
The drum car in memory is an instrument for recording mileage first invented by China in the 3rd century. Unfortunately, the original structure was lost, and it was only in the Song Dynasty that it was successfully rebuilt by Yan Su.
The guided car and drum car in memory all work by gear transmission principle. Its appearance reflects the high level of China's vehicle manufacturing engineering technology more than 700 years ago, and it is an outstanding achievement of China's ancient technology.
History of automobile development-early period
The first steam car
1765, the Englishman watt invented the steam engine, leading mankind into the "steam engine era". Many inventors also applied Watt's invention to the design of "bicycle".
1769 It took France six years to build the world's first steam car with practical value. This strange car has a hardwood frame supported by three iron wheels that are more than one person high. There is a pear-shaped boiler with a volume of 50L in front of the car, and there are two cylinders with a volume of 1 1 gallon behind the boiler. The boiler transmits the movement of the piston to the front wheel through a simple crank, which makes the front wheel rotate. At the same time, the front wheel is still the steering wheel. Because there is a heavy boiler on the front wheel, it is very difficult to control the steering rod.
This steam car has a fatal flaw. After walking for 15 minutes, the pressure of the boiler is exhausted, so we have to stop and add water to boil it into steam, and the maximum speed is only 4 km/h.
Due to the difficulty in steering the steering rod, the car had many accidents during the test run. When I was going downhill near Sannu Arsenal, I bumped into the wall of the Arsenal because I couldn't turn in time. The world's first memorable car was hit beyond recognition.

The Golden Age of Early Steam Cars (1)
At the end of 18, there was an upsurge of research and manufacture of steam cars in European and American countries, and various steam cars came out one after another. The car body and other mechanisms are also improving rapidly. /kloc-in the 0/9th century, there was a heyday of steam cars.
180 1 year, Richard trey witrich built the earliest steam car in Britain. Two years later, Dai made a steam car that looked like a coach. This bus can take 8 people, setting a world record of 9.6km/h on a flat road and 6.4km/h on a ramp.
1825, the duke of England made the first steam bus. The engine of this car is installed at the rear, driven by the rear axle and steered by the front axle. It uses a clever special steering shaft design, the first two wheels do not bear the weight of the car, and the driver can easily steer by using the steering tiller, and then the front axle is guided by a shaft, which makes the steering easy and comfortable.
183 1 year, Jianei started the world's earliest bus operation with this car, so this car is also considered as the world's earliest bus.

The Golden Age of Early Steam Cars (Ⅱ)
1805, American Evans made an amphibious car with a steam engine for the first time. This amphibious vehicle was commissioned by the Port Authority of Philadelphia to clean up the port of Philadelphia. At first, it intended to build a dredger. Unexpectedly, after the ship was built, because the working place was not on the coast, the steam ship had to be transported to a place with a port. Evans installed four wheels at the bottom of the boat and drove them with the steam engine on board. In this way, the ship was transported to the port. Therefore, dredgers have become amphibious vehicles. It has also become the originator of modern amphibious vehicles.
1928, the French cooperated with Quayle to build a steam-driven car. For the first time, the car adopts the general arrangement scheme that the engine is placed at the front end of the car and driven by the rear axle. It is driven by a chain between the engine and the rear axle. In order to steer flexibly, the rear shafting consists of two half shafts connected by a differential. This is the first differential invented. In addition, the two small front wheels are elastically connected with the frame, which is called independent suspension. This independent suspension design was of epoch-making significance at that time. The design of Quayle's chain drive, differential and independent suspension has made great contributions to the development of automobiles and is still widely used in automobiles.

The decline of early steam cars
In the initial development period of steam cars, their design was very simple, that is, installing a steam engine on the chassis and wheels. In order to achieve a certain output power, it is necessary to have a boiler as large as possible; In order to achieve a certain journey, we must have enough water and coal; When the car body is heavy, a solid underframe and solid wheels are needed. In this way, the vicious circle, the car is getting heavier and heavier, and the operation is getting harder and harder.
Therefore, these large steam trucks are only suitable for scheduled round-trip driving, with fixed routes and coal and water supply along the way. Even so, there are still many inevitable defects, such as difficult braking, heavy car, narrow wheels, large inertia and insensitive steering. Sometimes you know you have to slow down and turn, but you can't slow down and turn. You can only watch the car hit an obstacle, or brake too hard and the axle is broken. What is even more frightening is that the boiler pressure is too high, which is difficult to control for a while, and boiler explosions often occur.
And riding this kind of car depends on the weather: on rainy days, the car cover is not tight, the road is muddy and unsafe; It is difficult to boil water in cold weather, easy to turn off the fire and drive slowly; No one wants to sit next to the boiler in hot weather; It depends on the wind direction on a windy day. When the wind is downwind, the smoke at the rear of the car will make passengers breathless.

Re-prosperity and final decline of early steam cars
/kloc-at the end of 0/9, with the development of capitalist industry and commerce, European and American governments deeply felt that carriages could no longer meet the needs of the times, so they began to vigorously promote electric locomotives. Under this call, the steam industry in various countries has developed rapidly like dew after a long drought.
1872, a Frenchman, Amede Parisian, built a four-wheeled steam bus, which was equipped with two V-shaped steam engines and equipped with a transmission and steering wheel similar to modern cars.
1883, a Frenchman, Dion Pudong, set up an automobile company to manufacture three-wheeled steam cars. Since then, the steam car has entered the stage of industrial production from a single trial production.
With the development of passenger cars, steam trucks have also developed. Trucks need great traction and can climb hills. The typical style of early steam trucks was that the engine was driven by front and rear wheels, and there was a spacious car slot.
(6): Four milestones in the history of automobile development.
The first gasoline-powered car
1885, German engineer karl benz developed a tricycle with a gasoline engine of 0.85 HP. Another German engineer, Godlib Daimler, has also developed a four-wheeled vehicle, which is driven by a gasoline engine with 1. 1 horsepower.
The first mass-produced car
1908, the first four-wheeled vehicle in automobile history-Ford Model T was born in the United States. Ford Model T changed the shape of previous vehicles and horses, combined with the innovation and improvement of functional configuration, and became the best personal transportation in the city at that time. In the first year of listing, it sold 65,438+09,000 vehicles. 150,000 T-cars were produced when they rolled off the assembly line in 920.
The first car marked automatic time.
The success of Volkswagen Beetle is well known: it broke the production record of Ford Model T.. At present, Volkswagen has introduced a new beetle, which has aroused great interest. Its advantages are durability, no luxury and popular price.
The first mini-car
1959 "Mini (mi? Ni) "The automobile triggered the revolution of automobile technology. This small car has made a breakthrough in concept, and won many championships in car races at the same time. Today, 40 years later, this car is still popular, and almost all companies have imitated the design of "mini-car", making it the most family-oriented car.
(7): The development history of several major automobile companies.
Ford Motor Company
Ford Motor Company is one of the top ten automobile industry companies in the world. Is a comprehensive multinational monopoly industrial group mainly producing automobiles, and its business scope covers electronics, aviation, steel, military industry and so on. 190 1 was founded in Detroit, USA. At present, the company is headquartered in dearborn, Michigan, USA, with 370,000 employees. The company has an engineering research institute? ⒅⒅ ⑸ ⒁ ⒁ ⒁ ⒁ ⒁ ⒁ ⒁ ⒁ ⒁ ⒁ ⒁ ⒁ ⒁ ⒁ ⒁ ⒁ ⒁? Do 9？ Mirror?

Ford I, the founder of the company, is the son of a farmer. He is called the founder of modern automobile. He designed the Ford Model T and assembled it on the assembly line. One car can be produced every 10 second, which greatly reduces the production cost and creates a production record of 20 years150,000 vehicles. At the same time, Ford can produce 65,438+0965,438+065,438+0 ~ 65,438+0927 cars.
Old Ford founded the car company twice and failed. The third time, he hired experts to predict the market, put forward the idea of cheap cars for him and established a widely distributed sales system. The designer who enjoys the reputation of "mechanical genius" designed the production line for him. With the completion of these tasks, his Model T has been continuously integrated into the market. When he achieved decisive success and ascended the throne of "automobile king", he turned a deaf ear to these heroes and started personal dictatorship and family monopoly. At that time, none of the company's more than 500 senior staff had received higher education. Financial chaos to the point of continuing to pay the dead employees. As a result, GM came from behind. At the time of the company crisis, Ford II, with a high degree of education, took office with a group of think tanks. The company's operating conditions are gradually improving. But the family's bad habits made Ford II repeat the same mistakes. He went his own way and fired Yaka, an automobile talent who created hundreds of millions of dollars for him, which shocked the ruling and opposition parties.
In just two years from 1980 to 1982, the company lost $3 billion. On the verge of bankruptcy. In another crisis, Ford II retired with 40% of the company's shares. Decades of history has proved that under certain conditions, property ownership and management rights should be separated. After the new leader took office, he reformed the management system, mobilized the enthusiasm of workers to participate in management, and took a series of measures for the revitalization of the company. 1989 turnover reached 96.9 billion dollars. Sit firmly in the second place in the American auto industry.
(8): General Motors
The logo of the automobile company, in which "GM" is General Motors.
The abbreviation of (General Motors) is taken from the first letter of the first two words.
General Motors is the largest automobile company in the world, with an annual gross industrial output value of over US$ 6,543,800 billion. Its logo GM is taken from the first letter of the English word General Motors. 1908 was developed by william durant on the basis of Buick Motor Company and established in Detroit, USA. The current headquarters is still located in Detroit. In addition to producing and selling automobiles, it is also involved in aerospace, electronic communication, industrial automation and finance. From automobile production? Mildew? Juji block? What does Kangnang mean? About 0%.
General Motors ranks first among the 500 largest enterprises in the United States and second among the largest industrial enterprises in the world. It employs 80 employees in the United States and around the world. What about planting pods? In 0 countries and regions, the annual output of GM family cars reaches 9 million.
General Motors has six automobile departments in the United States, namely Buick, Oldsmobile, Cadillac, Chevrolet, Pontiac and GMC. In addition, there are many branches around the world, among which GM's European branch is the largest, and Opel and Foxhall have an annual output of over one million cars. Not long ago, General Motors acquired British Lotus Automotive Engineering Company, which is the most advanced sports car research and production department in the world, adding strength to the GM family.
General Motors is one of the first super-large enterprises in the United States to implement joint-stock system and expert group management. The cars produced by GM typically show the characteristics of American cars, such as luxury, spaciousness, comfortable interior, high speed and great reserve power. In addition, GM attaches great importance to quality and the adoption of new technologies. Therefore, universal products have always enjoyed a high reputation in the eyes of users.
(9): Mercedes-Benz Automobile Company
Mercedes-Benz
The trident symbolizes the desire to conquer land, sea and air. This logo was produced after the merger of Daimler and Mercedes-Benz. Daimler's original trademark is three-pointed star, and Mercedes-Benz's trademark is double-circle "Mercedes-Benz". After the merger of the two, Daimler-Benz's trademark is a three-pointed star in a single circle.
Mercedes-Benz Automobile Company is the oldest manufacturer in the world, which is famous for producing high-quality and high-performance luxury cars. It is also one of the top ten automobile companies in the world. Germany sells first and second. It was founded in 1926 by Karl Benz and gottlieb daimler, who are praised as "the father of automobiles" by the world.
The predecessor of Mercedes-Benz Automobile Company is the Mercedes-Benz Automobile Factory and Daimler Automobile Factory, which were established in 1886. 1926, the two factories merged into Daimler-Benz Automobile Company, which was originally divided into the so-called Mannheim version and the Stuttgart version. 1936, the product is named Mercedes-Benz. 1945, Mercedes-Benz began to produce trucks, 1946, and resumed the production of cars, gradually restoring its position as the leading manufacturer of high-end cars in the world. 1989, in order to facilitate management, the company was reorganized into Daimler-Benz Industrial Group, and its automobile department was renamed Mercedes-Benz Automobile Company.
Headquartered in Stuttgart, Germany, Mercedes-Benz employs 6.5438+0.85 million people. Annual output of 600,000 cars. The management style of Mercedes-Benz Automobile Company is consistent, and it does not pursue the expansion of automobile production, but only pursues the production of high-quality, high-performance and high-grade automobile products. Among the top ten automobile companies in the world, Mercedes-Benz has the smallest output, less than 6.5438+0 million vehicles, but its profit and sales volume are in the top five. Mercedes-Benz's lowest-level car also costs more than $654.38 +0.5 million, luxury car costs more than $654.38 +0.5 million, and mid-level car costs about $40,000. In addition to high-end luxury cars, Mercedes-Benz is also the most famous manufacturer of buses and heavy trucks in the world. Mercedes-Benz has all kinds of trucks, special cars and buses. Only the basic types of trucks are l 10. Mercedes-Benz is also the largest heavy-duty automobile manufacturer in the world. Its all-wheel drive 3850AS truck has a maximum power of 368 kW and a traction capacity of 220 tons. 1984 Mercedes-Benz introduced new trucks ranging from 6.5 tons to l 1 ton, and adopted new technologies such as air brake, servo steering gear and electronic brake anti-lock device, which shocked major truck companies.
Mercedes-Benz has 6 subsidiaries in China, 23 subsidiaries abroad, and liaison offices, sales points and assembly plants all over the world. In 1980s, Mercedes-Benz cooperated with China North Industries Company to transfer the production technology of heavy vehicles to China. Now, the northern industry has been put into mass production. The new car products of Mercedes-Benz Company include four series of Mercedes-Benz W20 1, W 124, R 129 and W 126.
