One of the main benefits of parabolic leaf springs is that they use less steel, which means that you can reduce the weight added to the vehicle. They are also known to provide smoother and less stiff rides because of their flexibility. Compared to a standard semi-elliptic leaf spring, a parabolic leaf spring has a lighter unsprung weight. A vehicle’s unsprung weight refers to the part of the vehicle that moves up and down when exposed to road irregularities. Aside from that, a parabolic leaf spring can eliminate inter-leaf friction as long as the leaves don’t touch. This leads to better ride quality and fewer chances of rusting. For a quieter ride, silencer rubber pads can prevent the leaves from touching. Overall, a parabolic leaf spring can provide a comfortable ride with any load. For many, it’s considered to be more flexible than standard leaf springs. Finding the right parabolic springs, not all parabolic leaf springs are the same because there will be some variations when it comes to the number of leaves or the stiffness of the spring. So it’s best to research and window-shop first before deciding on a final product. A professional can help you find the right parabolic leaf springs for your vehicle. Be sure to look for suppliers that offer technical consultation, so you can better understand what product matches your needs.
Provide different types of leaf springs which include conventional multi leaf springs, parabolic leaf springs, air linkers and sprung drawbars.
In terms of vehicle types, it include heavy duty semi trailer leaf springs, truck leaf springs, light duty trailer leaf springs, buses and agricultural leaf springs.
