A16-146950 Load-Bearing Leaf Springs for Freightliner

1.Will the leaf spring really go the distance? Stop guessing—let fatigue testing call it.

2.One batch is tough and the next is tired—why? Find the root cause and lock the process for steady durability.

We mount the leaf spring on a test rig that pushes and releases it over and over—thousands to millions of times—just like road bumps do.This gives a quick, accurate measure of fatigue resistance without doing long road tests.

1.I see tiny cracks on the leaf spring surface or edges—how can we fix or prevent them?

2.Why is the spring cracking early, and what simple steps can reduce that risk?

Carry out shot peening strengthening at the leaf spring stretched surface; under the state of prestressing, the even and lasting residual stress distribution can be obtained, and the fatigue life will be improved.

1.The spring breaks too soon—how can we boost its fatigue strength?

2.How to reduce the risk of cracking on leaf spring?

After heating the leaf spring to the right temperature, we cool it fast in a specially formulated high-speed quench oil. That even cooling turns the steel into uniform martensite through the thickness—giving steady hardness and strength.

1.The leaf spring rusts easily in humid or salty conditions—how can we protect it?

2.Coating is uneven or too thin in gaps and corners—how do we make coverage uniform?
