Unlike mainly known automotive parts, leaf spring is one of those components whose importance cannot be realized until it breaks or wears out. Leaf spring has been there from medieval times to improve the performance of the suspension system. Originally known as laminated springs or carriage, leaf springs are an integral part of a vehicle suspension system. It is also responsible for maintaining the grip of the tyres and regulates the wheelbase lengths while slowing down or speeding up the car. In order to control the axle damping and height of the ride, leaf springs in automobiles are crucial. It is the same in both manual and automatic transmission.
This arc-shaped designed automotive component is a composition of a slender piece of steel, stacked with smaller pieces and are bolted together to form bow-like item. The quality of material used is pretty important, as it carries a huge amount of weight. The car leaf spring is attached to the rear axle and offers support against the additional weight added to the vehicle. This prevents the axle from buckling.
