Automotive suspensions are systems that connect a vehicle's body to its wheels, allowing for a smooth ride and better handling. They absorb shocks from the road, helping to maintain tire contact and stability. Key components include springs, shock absorbers, and control arms, which work together to manage the vehicle's weight and movement. There are different types of suspensions, such as independent and dependent systems. Independent suspensions allow each wheel to move separately, improving comfort and traction. In contrast, dependent suspensions link the wheels together, which can be simpler and more durable but may compromise ride quality.
