What is?
is most widely used in automobile suspension of an elastic member, which is composed of several sheet width but different length (the thickness may be equal, or may not be equal) alloy spring piece elastic beam formed by a combination of approximately equal intensity.

Function
by the middle of the leaf spring U-bolts (also known as horse bolts) secured to the axle, both ends of the roll to the frame bracket otic articulated pin. Thus, by the leaf spring connecting the axle to the vehicle body, functions as a buffer, damping, force-transmitting.

Characteristics
The advantage is a simple structure, reliable, low cost, easy maintenance. It is the resilient suspension element, the suspension means and a guide. One end of the frame is hinged, various forces and moments can be transmitted, and determines the track runout of the wheel. At the same time, it itself has a certain frictional damping effect. Threefold, it is widely used on non-independent suspension.
The disadvantage is that only a non-independent suspension, heavy weight, high rigidity, poor comfort, longer longitudinal dimension, is not conducive to shorten the front suspension and rear overhang of the car, is connected to the frame ofLeaf spring pin easily wear.
Despite many shortcomings, but the leaf spring is still a lot of variety on car use. To improve the performance of the leaf spring, reduce weight, improve life, it appeared tapered leaf springs, single spring.
