Car suspensions are systems that connect a vehicle's body to its wheels, allowing for a smooth ride and better handling. They absorb shocks from bumps and uneven surfaces, helping to maintain tire contact with the road. This improves safety and comfort for passengers. The main components of a suspension system include springs, shock absorbers, and control arms. Springs support the vehicle's weight and allow for vertical movement, while shock absorbers dampen the motion, preventing excessive bouncing. Together, these parts work to enhance driving stability and overall performance.
