From the design and technical characteristics, passenger cars are mainly used to carry passengers and their carry-on luggage and/or temporary items, including the driver's seat. No more than 9 passenger cars. Engine is the power device of automobile, which consists of two mechanisms and five systems: crank-connecting rod mechanism, valve train, cooling system, oil supply system, lubrication system, ignition system and starting system. However, diesel engines have fewer ignition systems than gasoline engines. Automobile braking system can be divided into hand braking system, dynamic braking system and servo braking system. The braking system with the driver's body as the only braking energy is called human body braking system; A system that relies entirely on potential energy is called a dynamic braking system. Potential energy is air pressure or hydraulic pressure converted from engine power. The above are some basic knowledge of automobiles, and a deeper understanding needs our personal experience.
Cars are vital to our daily life. No matter whether there is a car or not, people should know something about cars. After all, cars are a common topic, which can also play a certain safety role in driving. So, how can we learn about cars quickly?
1. Read more books and magazines about cars. We can usually read more books and magazines about cars. These books and magazines can learn more about cars in detail and accurately. This is a quick way to learn about cars.
2. Use network tools to quickly understand vehicle knowledge.
We can use mobile phones and computers to inquire about our car knowledge. Through the internet, you can keep track of the car's dynamics anytime and anywhere. No matter where you are, as long as you have the internet, you can know. This is a good method. For those who don't know, you can find a solution through online search, so as to quickly understand automobile knowledge.
3. Know more about the real thing of the car and do more operations. If you want to know the knowledge of the car quickly, you must see the real thing of the car and understand its structure. In this way, as long as you see the knowledge of cars, you will know what parts and types of cars are. It is easier to accept the knowledge about cars, so we learn faster. If there is an opportunity and a lot of operations, you can experience the real feeling of the car, which is very useful for quickly understanding the knowledge of the car. The body frame is the basis for installing all components. The chassis of this car includes engine, gearbox, wheels, suspension and brakes.
Most cars use a load-bearing body. The girder of the bearing body is integrated with the shell, which is more light and comfortable.
As far as the chassis is concerned, there are two front and rear sub-frames, so the front suspension of the engine gearbox of the front drive of the transverse engine is fixed on the front sub-frame and the rear sub-frame is fixed on the rear suspension. If it is a longitudinal engine rear-drive vehicle, only the engine and suspension system are fixed on the front subframe, and the rear subframe has a rear suspension and a differential.
There are many driving forms of automobiles, such as front drive, front four-wheel drive, front rear drive, center rear drive, center four-wheel drive, rear four-wheel drive, rear rear rear drive and so on. General family cars use front wheels, so the front wheels are generally transverse engines. The front and rear drives are usually longitudinal engines. Some front four-wheel drive vehicles use transverse engines, and some front four-wheel drive vehicles use longitudinal engines.
So there is a lot of knowledge about cars that we need to take the initiative to understand. Let's go
