Cars are our favorite travel tool at present, and the existence of cars solves our travel problems. It turns a long distance into a short time, and the comfort in the car is also very good. So, for veteran drivers who have been driving for many years, have their friends encountered some minor problems? For example, regarding the issue of abnormal noise in the rear wheels of cars, today's car editor will briefly introduce to friends the cause of abnormal noises in the front wheels of cars.
Causes of abnormal noise in the front wheel: What is the problem of abnormal noise in the front wheel?
First, the gap between the ball joint bracket swing arm and the chassis is too large. Poor load-bearing of the front wheels of some models can also cause the gap to be too large.

Jet propulsion
In 1680, the famous British scientist Newton conceived a plan for a jet car. Steam was injected through nozzles to propel the car, but failed to make it happen.
Steam power
In 1769, French N· J· New York manufactured a three-wheeled vehicle driven by steam generated by gas combustion. But the speed of this kind of car is only 4 kilometers per hour, and it is very troublesome to stop every 15 minutes to refuel the boiler. Later, the car crashed into a brick wall during a trip and was torn to pieces.
In 1879, German worker Karl Benz successfully tested a two-stroke experimental engine for the first time. In October 1883, he founded the "Benz Company and the Rhine Gas Engine Factory; in 1885, he manufactured the first motor vehicle patented by Benz in Mannheim, which was a three-wheeled vehicle using 0.9 HP two-stroke single-cylinder gasoline engine. This car has some basic features of modern cars, such as spark ignition, water-cooling cycle, steel tube frame, leaf spring suspension, rear-wheel drive, front-wheel steering and brake handle. On January 29, 1886, German engineer Karl Meister Benz applied for a patent for his motor vehicle. In November of the same year, Karl Benz's three-wheeled motor vehicle obtained German patent rights (Patent No.: 37435a). It is recognized as the first modern automobile in the world. Based on the above reasons, most people basically regard 1886 as the first year of the automobile. Some scholars also regard the year when Carl M. Benz built the first three-wheeled automobile (1885) as the year when the automobile was born. One year.
In 1829, James of England invented a steam car with a speed of 25 kilometers per hour, which could be used as a large car. The car was equipped with a heavy boiler and lots of coal. It emits black smoke, pollutes the streets, makes rumbling noise, and causes frequent accidents. In 1860, French worker Lunoir invented the internal combustion engine and used a gas engine of about 1 horsepower to drive a car, but the effect was not good. However, cars are caused by this internal combustion engine. Since then, many people have wanted to improve the internal combustion engine and need to use it in cars. In 1882, German engineer Wilhelm Daimler began researching internal combustion engines. He invented an automatic ignition device that used an electric spark to ignite the engine, and then based on this invention, he created an excellent gasoline engine. This engine rotates at 900 rpm, has a simple and compact structure, and can produce a lot of power. In 1883, Daimler completed this gasoline engine, and the next year began installing it on two-wheeled vehicles, three-wheeled vehicles, and four-wheeled vehicles to create gasoline-powered vehicles. In particular, the gasoline-engine four-wheel truck manufactured in 1886 was equipped with a 1.5-horsepower engine and could reach 18 kilometers per hour.
Gasoline
1885 was the decisive breakthrough in the invention of the automobile. At that time, Benz, who worked at the same factory as Daimler, was also working on cars. In 1885, almost at the same time as Daimler, he built a gasoline engine, installed it on a car, drove it at a speed of 12 kilometers per hour, and achieved success. In this year, Butler in England also invented a car with a gasoline engine. In addition, Bernard of Italy also invented the car, and Puchlov and Vorobov of Russia invented cars equipped with internal combustion engines.
Power
The first person in the world to study electric vehicles was the telegraph device completed in the laboratory by Hungarian engineer Anyos Jedlik Niedrik in 1828.
The first practical electric car was invented by American Anderson between 1832 and 1839.
The battery used in this electric car is quite simple and cannot be recharged. In 1899, Germany's Porsche invented the in-wheel motor, which replaced the chain drive commonly used in automobiles at that time. Soon
the Lohner-Porsche electric car was developed, using lead-acid batteries as the power source and directly driven by the front wheel hub motor. It was also the first car named after Porsche. At the 1900 Paris World's Fair, this car was the Touareg
The name Contente made its debut, causing a sensation.
Subsequently, Porsche also installed two in-wheel motors on the rear wheels of Lohner-Porsche, thus creating the world's first four-wheel drive electric vehicle. However, the battery used in this car is basically very large in size and weight, and its top speed is only 60 kilometers per hour. In order to solve these problems, in 1902, Porsche installed an internal combustion engine to generate electricity and drive a wheel hub motor on this electric car. This was also the world's first hybrid car.
In 1620, Italian Blanca invented the "counterattack steam turbine" to drive a unicycle. In 1766, British inventor James Watt (1736-1819) improved the steam engine and started the first industrial revolution.
In 1672, the Jesuit Ferdinand Verbister designed a steam-powered car for the then Chinese emperor. He is a 65cm long toy car that cannot carry people or a driver. I'm not sure if the designed car was successfully built. This was probably the earliest car designed.
In 1769, French army engineer Nicolas-Joseph Conot built the first automobile powered by a steam engine. It was the world's first motor vehicle accident when the steering system failed during a trial run and it crashed into the wall of an arsenal. In 1977, Nicholas Meadow; Joseph Meadow; New Zealand improved the steam car, with a speed of 95,000 meters per hour and towing 4-5 tons of cargo.
In 1994, Streeter, an Englishman, first proposed the idea of ??mixing fuel and air to create a mixed gas for combustion. In 1796, Italian scientist Waltz invented the world's first storage battery, which brought a historic turning point to the birth and development of automobiles. In 1981, Frenchman Leben proposed the principle of gas engine.
In 1803, French engineer Trevico (1771-1833) used a new type of high-pressure steam engine that could carry 8 people at an average speed of 13 kilometers/hour. Since then, steam engine-driven automobiles have been used in practice.
In 1838, British inventor Hennart invented the world's first internal combustion engine ignition device, which was called "a revolution in the history of world automobile development".
In 1860, French electrical engineer Lionel built the first gas engine that used an electric spark to ignite gas. In 1862, French electrical engineer Lionel developed the two-stroke internal combustion engine. Others began working on four-stroke engines.
In 1867, German engineer Kauros & Otto (1832-1891) successfully developed the world's first reciprocating piston four-stroke gas engine. In 1876, Kauros & Otto built the first four-stroke internal combustion engine and made it a single-cylinder horizontal internal combustion engine with a compression ratio of 2.5.
In 1885, this was the moment when the truly modern automobile was born. This year, German engineer Carl Meister-Benz built a three-wheeler with a 0.85-horsepower gasoline engine in Mannheim. This car with an internal combustion engine is considered the world's first automobile because it was the first to be powered by gasoline rather than a steam engine.
In 1886, the Mannheim Patent Office approved Karl Meister; Mercedes-Benz applied for a patent for the three-wheeled car it successfully developed in 1885. This day is called the birth day of modern cars by most people. The next year, Germany's Daimler built the world's first four-wheeled vehicle. After that, German Kauros & Otto announced that they would give up the four-stroke engine patent, and basically anyone can make it at will.
On January 29, 1886, Carl Benz obtained the world's first automobile engine patent. In July of the same year, the world's first four-wheeled vehicle was officially launched. In 1888, French self-driving businessman Emile Mido Rogers obtained a license from Mercedes-Benz and began producing commercial vehicles.
