What is a non load bearing body? What is a load bearing body?

What is the difference between a load-bearing body and a non-load-bearing body?

The whole body of the load-bearing body car is integrated, there is no girder through the whole, the engine, transmission system, front and rear suspension and other components are assembled into the body, and the body load is transmitted to the wheels through the suspension device. The load-bearing body of the car is very smooth on the straight road, low natural frequency, low noise, light weight, and is widely used in cars. Of course, the strength of the chassis is not as strong as the non-load-bearing body with girder structure, and the body will be deformed when the four wheels of the car are stressed unevenly.

The non-load-bearing body has a girder running through the entire body structure, and the chassis has high strength and good anti-bump performance. Even if the four wheels of the car are not evenly stressed, they are borne by the frame and will not be transmitted to the body, so the body is not easy to twist and deform.

1. The so-called load-bearing type and non-load-bearing type are all for the force of the body. In the process of driving, the car will be affected by a variety of forces, such as rolling resistance, the reaction force of the road to the car, the torsional moment of the body on uneven roads, and so on.

2. There are also the parts of the car itself, such as the engine, gearbox, drive axle, suspension system, etc., their installation position on the car, which parts bear their weight and the reaction force generated when they work.

3. If these forces are borne by the body, it is called a load-bearing body; If these forces are not borne by the body, but by the frame, it is called a non-load-bearing body. The main difference between them is the presence or absence of a frame.

The differences are as follows: 1. Compared with the non-load-bearing body, because the load-bearing body does not have rigid girders, the overall weight of the vehicle is lighter, the cost is lower, and it is also fuel-efficient to run.

2. Compared with the non-load-bearing body, the load-bearing body will collapse on the front and rear axles when encountering an impact, which can absorb part of the impact energy for the personnel in the car and better ensure the safety of the personnel in the vehicle.

3. Because the load-bearing body does not have a rigid girder at the bottom, the load-bearing body is inferior to the non-Hexian load-bearing body in terms of rigidity and off-road ability, and is more suitable for driving on urban roads.

4. Because the load-bearing body installs all the auto parts on the body, and the various parts and the body are often connected together by welding, some parts may be more time-consuming and laborious in the later maintenance and replacement.

5. Because the non-load-bearing body increases the girder located at the bottom of the vehicle, and the bottom girder provides a stronger body rigidity for the body, the non-load-bearing body can be unimpeded in various rugged and potholed mountain roads.

6. Because the bottom girder of the non-load-bearing body and the two major structures of the body are separated, and there will be a lot of sound insulation materials embedded in the middle, the non-load-bearing body can provide better sound insulation effect for passengers during driving.

1. Compared with the non-load-bearing body, because the load-bearing body does not have rigid girders, the whole rolling bridge of the vehicle is lighter, the cost is lower, and it is also fuel-efficient.

The difference between the load-bearing and non-load-bearing bodies is mainly the different structure, the load-bearing type is lighter, and the latter is heavier but its structure is more stable.

The advantages of the load-bearing body are:1Compared with the non-load-bearing body, the load-bearing body will have a lighter overall mass because it does not penetrate into the girder early, so it is more fuel-efficient, and the center of gravity is relatively low.

2.The front and rear frames of the load-bearing body collapse in the event of a collision to protect the people in the vehicle by absorbing the impact force, so it is relatively safer.

The advantages of the non-load-bearing body are:1Rigid frame beams absorb and resist torsional forces well, which greatly reduces the impact on the body.

2.Because the chassis is separated from the body, a variety of shock-absorbing materials are embedded in the middle, and the abnormal noise is less when driving in complex road conditions.

The load-bearing body, as the name suggests, is to carry the parts of the car manufacturer, such as the engine, gearbox, suspension and so on. The parts and components of these cars are mounted directly on the body, they are a whole. In addition to its inherent load function, the load-bearing body also directly bears the role of various load forces.

Load-bearing body is a great improvement in terms of stability, it has the advantages of small mass, low height, easy assembly, etc., most of the cars use this kind of body structure.

The non-load-bearing body retains the traditional chassis girders. The engine, gearbox and other parts of the car are installed on the chassis girder, and the body is not carrying the auto parts. Therefore, theoretically, an SUV model with a non-load-bearing body can run even if the body is removed.

The non-load-bearing body is relatively bulky, with large mass and high height, and is generally used in trucks, buses and off-road vehicles, and is also used by some high-end cars, because it has good stability and safety.

The definition of non-load-bearing body body is as follows: 1. Non-load-bearing body: The frame of the non-load-bearing body is composed of many beams above to form a moment-like structure.

The frame carries the entire body, the engine, suspension and body are mounted on the frame, and the frame is connected to the wheels by front and rear suspension devices. The frame has propellers for fixing the body, as well as a base for fixing the springs. The role of the body is to provide a comfortable and safe environment for the driver and passengers, as well as to improve aesthetics.

2. Load-bearing body: The feature of the load-bearing body is that there is no frame, and the whole body is integrated. The engine, drivetrain, and suspension are all installed in the designated position of the body.

In addition to its inherent bearing function, the load-bearing body should also directly bear the role of various load forces. Nowadays, the load-bearing body is used to ensure the safety of the people in the car through energy absorption and collapse in the event of a collision with different strengths, and the safety and stability of the mountain return are greatly improved, but the noise and vibration generated are relatively large. The rigidity and load capacity of the vehicle body are relatively weak, so the general professional off-road vehicles and freight vehicles do not use this structure.
