What is the role of springs in a vehicle's suspension?

Springs in a vehicle's suspension play a crucial role in absorbing energy when the vehicle encounters bumps or irregularities in the road surface. This absorption helps to maintain the ride height by controlling the compression and extension of the suspension system. When the vehicle hits a bump, the springs compress to absorb the kinetic energy generated by the impact, preventing excessive transfer of force to the vehicle's body and providing a smoother riding experience.

The design and characteristics of springs ensure that they can return to their original shape after compression, thereby maintaining the correct ride height over time and contributing to vehicle stability. This function is essential for both comfort and handling, as it helps keep the tires in contact with the road, enhancing traction and overall driving dynamics.
