What is the primary function of suspension systems in a vehicle?

The primary function of suspension systems in a vehicle is to keep the axles in place. The suspension system is designed to manage the vehicle's dynamics, allowing for stability and support of the vehicle's weight while providing a comfortable ride. It connects the vehicle's body to its wheels, enabling the tires to maintain contact with the road surface, which is crucial for traction, handling, and overall safety. By keeping the axles aligned and in place, the suspension system ensures that weight is properly distributed, helping to prevent excessive wear on tires and other components.

While other aspects of vehicle performance, such as fuel efficiency and braking, can be indirectly influenced by the suspension, those are not its primary functions. Fuel efficiency often relates more to engine performance and aerodynamics rather than suspension mechanics. Tire pressure management is typically a separate system and does not fall under the scope of suspension functionality. Similarly, while the suspension can impact overall handling which might affect braking slightly, the primary role of the suspension remains focused on maintaining axle stability and supporting vehicle integrity.
