What is NOT a function of a vehicle's suspension system?

The suspension system of a vehicle serves multiple important functions that collectively enhance ride quality, handling, and vehicle dynamics. One of its primary roles is to support the load of the vehicle and its occupants while maintaining comfort and control during motion. Additionally, the suspension system articulates the load during motion, allowing for relative movement between the vehicle body and the wheels, which is essential for stability and traction.

Another critical function is removing excess energy, such as oscillations and vibrations, caused by road imperfections. The suspension absorbs this energy, resulting in a smoother ride. This is achieved through components like shock absorbers and springs that work together to dampen movements.

In contrast, providing a rigid foundation for frame support is not a primary function of the suspension system. While parts of the suspension must connect to the frame to provide structure, the purpose of the suspension is largely to allow for movement and adaptability rather than to serve as a rigid foundation. The vehicle's frame and structure are designed separately to support loads and provide integrity, but the suspension's role is specifically focused on improving ride comfort and handling characteristics rather than rigidity.
