What are the disadvantages of a body-on-frame structure?
1 Answers
The following are the disadvantages of a body-on-frame structure: 1. The body-on-frame structure is relatively bulky, heavy, and tall, typically used in trucks, buses, and off-road vehicles. Some high-end sedans also use it because it offers better stability and safety. 2. The body and frame are rigidly connected, which can lead to less smooth driving on highways and may cause vibrations. 3. In dangerous situations (such as a rollover), the heavy chassis can pose a fatal threat to the relatively weaker body (a unibody structure does not encounter this issue as its body is integrated). Additional information: The advantage of a body-on-frame structure is that it has an independent frame, providing higher chassis strength and better resistance to bumps. Additionally, uneven forces on the four wheels are borne by the frame and not transmitted to the body. This is why SUVs and off-road vehicles often use this structure.
