Frame vs. Chassis: What's the Difference?
By Janet White || Published on December 15, 2023
A frame is the structural, load-bearing part of a physical structure, while a chassis is the base framework of a vehicle, including the frame and wheels.
Key Differences
The frame in various contexts refers to a rigid structure that shapes or supports something, like in buildings or eyeglasses. A chassis, specifically in automotive contexts, is the base frame of a vehicle along with its integral components like engine, transmission, driveshaft, differential, and suspension.
A frame is widely used across various fields, from construction to art, implying any structural system that bears load. The chassis, however, is predominantly used in automotive and machinery contexts, indicating the lower frame of a vehicle or machine, integrating key operational parts.
In architecture, the frame is the skeleton that holds everything together, be it a building or a piece of furniture. In vehicles, the chassis acts not only as the frame but also integrates key components, serving as the vehicle's foundational structure.
Frames can be made from a variety of materials (wood, metal, plastic) and designs, depending on their purpose. Chassis designs are more complex, often tailored to specific vehicle types and performance requirements, typically made from sturdy materials like steel or aluminum.
Frames have evolved from simple wooden structures to complex architectural designs. Chassis development has been more dynamic, influenced by advancements in automotive technology, leading to various types like ladder, monocoque, and tubular space frame chassis.
