What are the three big parts of a car? Introduction of three parts of automobile.

At present, when buying a car, friends basically look at the configuration. The more configurations a car comes standard, the more popular it is. At present, many domestic cars rely on&; Ldquo heap configuration &; Rdquo has already started. Most friends who buy cars are basically concerned about low-end models. After all, three cars are basically the same, so what are three cars? Here is a brief introduction to my friends.

What are the three major parts of a car? Mdash & ampMdash engine

If a car is compared to a person, the engine is equivalent to the heart. Of course, this is only for traditional fuel vehicles. At the same time, the engine structure affects the dynamic performance symptoms of the whole vehicle. Usually, the number of cylinders of an engine varies from 4, 5, 6, 8, 10, 12, and the same arrangement of different cylinders is not necessarily the same. In-line, horizontally opposed, "V-shaped" and "W-shaped" arrangements are usually encountered. Generally, the cylinder diameter is similar, the number of cylinders is large, and the displacement is large. According to the position of the engine, it can include front, middle and rear, and the driving position can include front drive, rear drive and four-wheel drive. At present, most cars use front drive. This arrangement can save the transmission shaft device, save the waste in power transportation, reduce the vehicle weight and improve the stability of high-speed driving, but when accelerating or uphill, the front wheel load is shortened and the traction is reduced. At present, the front four-wheel drive is mostly used in luxury cars and SUVs, which can make the handling performance of cars higher and the passability of off-road vehicles better. Many people pay attention to the intake form of the engine, and now there are two types: natural inhalation and turbocharging. Natural inhalation technology is mature, with high reliability and good ride comfort, but sometimes the power is too weak; Turbocharging is to compress the intake of the engine and conquer the market through fuel saving and strong power. However, because the power will be delayed for a period of time after passing through the air compressor and intercooler, the stability of the power may not be as good as that of self-priming.

What are the three major parts of a car? Mdash & ampMdash gearbox

The gearbox is responsible for transmitting the power generated by the engine to the wheels, and changing the speed of the car through different gear combinations, that is, we usually shorten the damage caused by gear shifting by shifting gears, and a clutch will be installed behind the engine to connect the gearbox. There are generally manual and automatic gearboxes. According to the structure, automatic gearbox can also include AT hydraulic gearbox, AMT mechanical automatic gearbox, CVT continuously variable gearbox, DCT dual clutch gearbox and so on. Manual gearbox has the advantages of fast response, great driving pleasure, good drivability and fuel saving, but it needs one foot to step on the other to shift gears, so it is inconvenient to use in cities.

The structure of AT gearbox is quite complicated, and the transmission efficiency is low, but the shift smoothness and reliability are basically good. AMT is similar to a manual gearbox, but the control is regulated by electronic control elements, which makes the shift feeling quite frustrating. DCT adopts two sets of variable speed gears. When using the first gear, the next gear is ready and the shift speed is fast, but the shift smoothness is slightly worse at low speed. CVT is theoretically the smoothest shift, but due to structural reasons, it can't bear too much at high speed.

What are the three major parts of a car? The mdash & ampMdash foundation

Chassis: The chassis of an automobile does not refer to a certain part, but a generalized whole part composed of transmission system, drive system, steering system and braking system. The function of the chassis is to support and install the engine and other parts and components of the car. Through development and change, it becomes the overall shape of the car, transmits power and makes the car move, so it makes sense to call the chassis the skeleton. The quality of chassis technology will affect the safety factor, handling, comfort and rationality of the car at the same time.

The above is a brief introduction of the three major parts of the car by the car editor. What about the introduction of the three parts of the car? The car editors briefly introduced the engine, gearbox and chassis to their friends, and the three car editors briefly introduced the patient knowledge to their friends. So how much do the friends basically know after reading the profile of the car editor? I hope the profile of Bianxiao Automobile can solve the problem for friends!
