10 hilariously insightful foreign words. A leaf spring is a simple type of suspension spring commonly used in vehicles. This type of spring is typically constructed of one or more flat, thin, flexible steel strips that are joined together in order to work as a single unit.
Adding leaves to a spring may severely overload the suspension parts or vehicle itself. A properly designed spring is a balanced spring, with leaves so graded or stepped in length, with regard to the other leaves, that each leaf carries its fair share of the load.pring length is measured along curve of main leaf. Springs of the progressive type not only give almost equal riding comfort for the lightly loaded and fully loaded vehicle, but they also have the additional advantage that there is less variation in spring deflection from light load to full load.
