What is leaf spring?

Leaf springs (Leaf Spring) automotive leaf spring suspension is the most widely used 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 sheet elastic beam intensity of a combination of approximately equal.

1. Noun interpretation leaf spring

Leaf springs (Leaf Spring) automotive leaf spring suspension is the most widely used of an elastic member, which is composed of several sheet width but not isometric elastic beam (the thickness may be equal, or may not be equal) an alloy of a combination of the leaf spring approximately equal intensity.

2. SteelWorks leaf spring

When the leaf spring is mounted in a vehicle suspension, the forward withstand vertical loads, each of the spring pieces were deformed by the force, the curved arch upward trend. At this time, axle and frame will be close to each other. When the axle and the frame away from each other, and the forward vertical load deformation suffered by the leaf spring will be gradually reduced, sometimes even reversed.

major force severe ear piece volume, the weak, to improve the forces of the main ear piece volume, often also bent end of the second sheet of the Word, the package sheet outside the main volume of the ear, called aural. In order to make the elastic deformation of each sheet may have a relative sliding movement, leaving a large gap between the main sheet and the second sheet pack Curl ear. Both ends of the leaf spring suspension does not make some of the Word, and the use of other support connections, such as rubber support pad.

flat rectangular plate shape curved to the number of sheets folded chassis spring, one end studs mounted on the hanger and the other end connected to a girder lug, the spring retractable. Currently applicable to some non-bearing body of hardcore off-road vehicles and passenger / truck.

3. The advantages and disadvantages of the leaf spring

● advantages

it has the advantage of simple structure, reliable, low cost, easy maintenance. It is a suspension ofAn elastic member, the guide means is a suspension. 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.

● disadvantages

The disadvantage is that only a non-independent suspension, heavy weight, high rigidity, poor comfort, longer longitudinal dimension, not conducive shortening the car front overhang and a rear suspension with leaf springs connected to the frame at a pin wear easily.

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.
