What makes parabolic leaf spring a highly effective suspension system?

A parabolic leaf spring is a type of suspension system used in many types of vehicles, including trucks, buses, and trailers. It consists of several layers of curved metal strips, or leaves, that are arranged in a parabolic shape. The parabolic shape allows for more flexibility and durability than traditional leaf springs, which are curved in a semi-elliptical shape.
The design of the parabolic leaf spring allows it to absorb shocks and vibrations from the road, providing a smooth ride for passengers and protecting the vehicle from damage. The springs work by compressing and expanding as the vehicle moves over bumps and uneven terrain, absorbing the energy of the impact and transferring it to the chassis.
