Parabolic springs consist of individual, parabolically rolled out leaves that can adjust to the loads they have to carry. Parabolic springs vary in thickness, ensuring an even distribution of stress. Lighter and thinner than multi-leaf springs, but still parabolic springs demonstrate enhanced durability and resistance. They help reduce the overall weight of the truck being 30% lighter which also results in reduced fuel consumption.
The beam spring is part of a quiet, convenient and modern air suspension system where the spring acts as the link between the axle and the chassis. The axles are controlled safely and stabilised, cushioning and absorbing braking forces. Beam springs, used in towing vehicles, have also proved effective as a spring system for trailer equipment.
Today, the comparatively heavy multi-leaf spring is mainly used in construction and agricultural vehicles. Not only can multi-leaf springs be manufactured easily and economically, they are also easy to repair and reinforce.
