Chassis and Suspension System

Suspension system is not chassis, which is a common mistake made by many people. The concept of chassis is larger than that of suspension, and it is a very complex geometry. The function of chassis is to install automobile engine, peripheral parts and assemblies to form the overall shape of automobile. It consists of four parts: transmission system, driving system, steering system and braking system.

Usually what we call suspension is only a part of chassis driving system (frame, axle, wheel, suspension).

Suspension and Suspension

Car owners’friends will find that some articles are called suspension while others are called suspension when they look up automobile information. So are there any differences between them?

In fact, suspension and suspension are the same thing, English is Suspension. But in the formal automobile textbooks of colleges and universities, they are called suspension, not suspension. We should respect the textbooks here. After all, they are the crystallization of the wisdom of many university professors. They are much smarter than those of us. In the following articles, I also use “suspension” instead of “suspension”.
