Today, I will give you a brief introduction to the structure of the car body. In general, you will first think of hatchback, hatchback, convertible and so on. In fact, there is nothing wrong with saying so.
However, generally, the lower body structure is classified according to the load-bearing mode of the vehicle. They are mainly divided into non load-bearing type and load-bearing type.
First, let's talk about the non load-bearing car body structure:
The non bearing structure is to install the engine, suspension, transmission and other mechanical equipment on the rigid frame, while the passenger's body is flexibly connected with the frame with rubber pads or springs.
The frame is connected with the wheels through the front and rear suspension devices. When it is designed, it does not consider the load-bearing of the body. Therefore, when your body is gone, you can still drive...
Advantages: good stability and safety, good anti bumping performance. When the force on the four wheels is uneven, the force is borne by the frame rather than transmitted to the body, and the whole vehicle is not easy to deform. Therefore, this structure is commonly used in off-road vehicles, buses and trucks.
Disadvantages: self weight and high height. With more frame between chassis and body, the whole vehicle will appear high. The cost is expensive.
The load-bearing car body structure is an integrated structure in which the engine, transmission system, suspension system and other components are installed on the car body without the frame.
The load of the vehicle body is connected with the wheels through the suspension device. With the more and more advanced structural technology of load-bearing vehicle body in recent decades, some vehicles will also install the subframe, and one end of the chassis part will be installed on the subframe.
It is commonly used in general cars and urban SUVs.
Advantages: smooth and comfortable driving, low inherent frequency, low noise outside the car, light weight and low floor inside the car. Because it is generally processed by thin plate and spot welding, it is easy to produce in mass.
Disadvantages: because the integrated manufacturing ensures the stiffness, it is difficult to be transformed, and the noise and vibration of the road and engine are easy to be transmitted into the vehicle.
