Suspension System with Combined Leaf and Helical Spring: A Review
Abstract: A good suspension system of any automobile vehicle must have minimum deflection, minimum weight, low maintenance and low operating cost with some other fine properties. Springs are major element of any suspension system and first line of its defense. If the suspension springs are rigid enough, they will not absorb road shocks efficiently, and if they are more flexible, then they will keep vibrating for a longer time even after …
