Advantages And Disadvantages Of Plate Springs

The advantages of plate springs are simple structure, reliable operation, low cost, and convenient maintenance. It is both the elastic component of the suspension and the guiding device of the suspension. One end of it is hinged to the frame, capable of transmitting various forces and moments, and determining the trajectory of the wheels. At the same time, it also has a certain frictional damping effect. Kill three birds with one stone, so it is widely used on non independent suspensions.
The disadvantages of plate springs are that they can only be used for non independent suspensions, are heavy, have high stiffness, poor comfort, have longer longitudinal dimensions, and are not conducive to shortening the front and rear suspensions of the car. The steel plate spring pins at the connection with the frame are prone to wear and tear.
Despite its many drawbacks, plate springs are still widely used in various cars. In order to improve the performance of plate springs, reduce weight, and increase service life, variable section panel springs, single leaf springs, etc. have emerged
