Leaf springs are an essential component of a vehicle's suspension system. They are responsible for supporting the weight of the car, absorbing shocks, and providing stability during acceleration and braking. There are several synonyms for leaf springs, including blade springs, lamellar springs, and semi-elliptic springs. Blade springs refer to their shape, which resembles a flat blade, while lamellar springs are made up of several layers or plates. Semi-elliptic springs have a slightly curved shape. Other terms that can be used to refer to leaf springs include suspension springs, arch springs, and cart springs, depending on the context and type of vehicle. Regardless of the term used, leaf springs play an important role in ensuring a safe and comfortable ride.
