In the context of school bus body systems, what is the purpose of the structural framing?

The purpose of the structural framing in school bus body systems is to provide support and integrity to the bus body. Structural framing is crucial as it forms the skeleton of the bus, ensuring that the body maintains its shape, stability, and strength while withstanding various stresses and loads during operation. This integrity is vital for the safety of passengers and the overall durability of the vehicle. It helps distribute forces encountered during driving, such as turns, stops, and impacts, thereby ensuring that the bus remains safe and functional over its lifespan. Without a robust structural frame, the bus would be vulnerable to damage, compromising safety and operational efficiency.

While improving fuel economy, allowing for easier repairs, and enhancing passenger comfort are important considerations in bus design, they are not the primary purpose of the structural framing. The framing's main role is to uphold the physical structure and safety of the bus.
