What are Monocoque Body and Body-on-Frame?
1 Answers
Monocoque and body-on-frame are classifications based on how a vehicle's structure bears loads. Below is a detailed introduction to monocoque body and body-on-frame: 1. Monocoque Body: A monocoque body does not have a separate frame; the body itself serves as the mounting base for the engine and chassis components, functioning as the frame and bearing all loads. This structure involves directly mounting chassis components (such as the engine and suspension) onto the body, primarily constructed with thin panels. 2. Body-on-Frame: In a body-on-frame design, the body is flexibly connected to the frame through rubber cushions or springs. The frame is the foundation that supports the entire vehicle, bearing various loads from the installed components. The body only bears the weight and inertial forces of the passengers and cargo, and the frame design does not consider the body's auxiliary role in load-bearing.
