What does a body-on-frame structure mean?
1 Answers
Body-on-frame refers to a chassis configuration where the frame carries the entire vehicle body, with the engine, suspension, and body all mounted on the frame. The frame features bolt holes for securing the body and bases for mounting springs. Here are the specific characteristics of a body-on-frame structure: 1. High body strength, as the steel frame provides strong structural rigidity. This is particularly important for trucks and off-road vehicles. The feedback from road bumps to the cabin is much milder because some vehicles use vibration-reducing methods to connect the body and chassis, resulting in a smoother and more comfortable ride on rough roads. 2. It has an independent frame with high chassis strength, commonly used in trucks, buses, and off-road jeeps. 3. Uneven forces on the four wheels are borne by the frame and not transmitted to the body, which is why SUVs and off-road vehicles often use this structure. Non-monocoque bodies are widely used in the bus industry. 4. The body and frame are connected by elastic components, providing certain cushioning and vibration-damping effects. This results in a more stable feeling when driving on highways.
