Parabolic Leaf Spring for Automobiles - Modern Approach of Leaf Spring

A leaf spring is a simple form of spring, generally used for the suspension in automotives. It is also one of the oldest forms of springing techniques used. It looks like a slender arc-shaped having length of a spring steel of rectangular cross-section. Axle is located at the center of the arc, at the end are the while tie holes which are being used for attaching to the vehicle body. Since 1970s Leaf springs were very common on automobiles.

The main feature that contributes to the smoothness of your vehicle is its suspension. Now days widely used suspension systems in motor vehicles is the Leaf springs. It is also known as a semi-elliptical spring or cart spring, looks like an arc-shaped length of a steel spring with a rectangular cross-section. We can attach a leaf spring directly to the both ends of the frame or directly to the one end generally the front end, while the other end is attached with the shackle, a short swinging arm. For the ease of riding in very heavy vehicles, A leaf spring made out of several leaves in several layers stacking at the top of each other often started with progressively shorter leaves is used to provide ease in riding in very heavy vehicles.

Modernization of Leaf Spring

A more modern implementation of old leaf springs is the parabolic leaf spring for automobiles. The new innovative design is characterized by the use of less leaves whose thickness varies from the center to the outer side following a parabolic pattern. This results in less inter leaf friction, because of which the only contact point between the springs in vehicle is at the end and the center where the axle is connected. Spacers used in the new design prevent the other parts collisions. Besides being less in weight the main benefit of parabolic springs is their greater flexibility, which is translated as a high ride quality of the vehicle. It gives us the high ride quality which refers to the high degree of safety to the riders from the uneven road surfaces and gives high level of comfort. Modified version of leaf springs the parabolic leaf springs for automobiles has better load bearing capacity with less weight.

Other benefits include improved fuel economy or load carrying capacity, cost effective, and reduced road damage for an equivalent axle weight.
