Recalling 70s，People will watch watches、Bicycle、Sewing machines are deemed to be the "three major pieces" of the times; entering the 1980s，The new "three major" color TV、refrigerator、The washing machine brought great convenience to everyone's life; entering the 1990s，Air conditioner、Computer、The video machine has become the "three major pieces" for new family life consumption。The change of "three major pieces"，Carrying the brand left by the times，I also witnessed the continuous improvement of living standards。

Enter the 21st century，Consumption tends to diversify，The Seabetcar was selected as a member of the new "three major pieces"，Consumers also pay attention to the "Appearance Association" that only pays attention to the appearance and configuration，Turn to the attention of the substantive components of the car。

As the saying goes: "layman looks at the fun，See the doorway "，Experts who really understand cars often take the car's engine、The "three major pieces" of the gearbox and chassis as an important criterion for considering cars。Then the problem is here，How important is these three major pieces?

Engine

The engine is known as the heart of the car，It is the source of the motorized，Responsible for turning the chemical energy of fuel into mechanical energy，to drive the vehicle forward。A good engine can bring us surging motivation，Strong and durable at the same time，Make people worry -free; an immature mobility allows you to run the repair shop on both ends for three days，Judging、Noise、A series of issues such as fuel consumption will also surround you all the time，So when choosing a car, you must first understand the engine of the heart instrument.，can we better help us buy a car that meets our needs。

gearbox

I believe that when you are studying at school in your driving school，I have heard "Hanging One Block，离，Give oil。"" "，I must have been abused by manual transmission，I have left a deep impression for us。If the engine is the heart of the car，That gearbox is the arteries of the car，It coordinates seabet mythe speed of the engine speed and the actual driving speed of the wheels。In the case where the engine rotation is unchanged，It enables the car to drive backwards; use empty gear，Interrupt power transfer，so that the engine can start、idle speed。It is related to whether the motivation of the engine can be efficient、Pingshun output，At the same time, it will also affect many aspects such as driving control comfort and fuel economy。

chassis

Many people compare the chassis to the bones of the car，It is support、Install the car engine and assembly of each component，Formed the overall shape of the car，and accept the power of the engine，Make a car exercise，Guarantee normal driving。The overall focus of the vehicle is reflected in the assembly process of the chassis，For example, whether there is abnormal noise when driving，How about the comfort of the car in the car when encountering bumpy road conditions，These are the standards for measuring the overall quality of a car。In addition，The quality of the chassis is directly related to driving safety，If the chassis is not good，Vehicles will "flutter" when driving at high speed，Turn from the steering is not precise，Easy accident。If the rigidity of the chassis is poor，will cause the car when an accident occurs，Can't achieve the due protection of drivers and passengers。
