Leaf Springs have been used since time immemorial for front and rear suspension purposes in automobiles. They are used as a link between the body and the wheels that absorb the load of the vehicle. The fact that leaf springs are still being widely used is a testimony of their flexibility and durability.

Leaf springs come in different types and each has its own significant attributes. When it comes to distributing heavy loads effectively, parabolic leaf springs are what one should consider. Parabolic leaf springs are an evolved version of the taper leaf spring but with a very important difference.

The ‘parabolic’ reference does not refer to the shape of the leaf spring but to the process in which the springs are tapered from the centre to the end that accurately manages the stress levels throughout the spring. The leaves are thicker in the middle and thin out at the end. Parabolic leaf springs distribute the force equally across the spring, making the ride a comfortable and quiet one.

Let us take a quick look at the major benefits of using parabolic leaf springs in place of the conventional ones.

Enhanced Flex

Unlike the traditional leaf springs, parabolic leaf springs have an enhanced flexibility. Each leaf of the parabolic assembly works independently without compromising the load capacity of the vehicle. This improved flex quality ensures a smooth and better ride.

Light in Weight

The components of the parabolic springs are less in weight which in turn, aids to the maximum performance of the mechanism.

Reduced Friction

Due to the gap between each of the parabolic leaves, the friction between them is reduced. The centre lines are also used to reduce friction and to prevent mud and water from blocking the gap.

Increased Load Capacity

The load-carrying capacity of parabolic leaf springs is higher as compared to the conventional springs. The springs are also stress shot in a controlled manner for an improved fatigue life.
