WHY LEAF SPRINGS?
Since we are a leaf spring production company, it's understandable that leaf springs are our passion... Leaf springs are indeed very efficient suspensions; here we explain both advantages and disadvantages.
ADVANTAGES
​
-
Simple and robust solution to carry heavy load
-
Cheapest solution for heavy duty commercial vehicles
-
It is not just a suspension element but a robust linkage between the axle and frame
-
It can take not only vertical load but also transversal forces
-
No need for additional stabiliser bar in many cases
-
In comparison to coil springs, leaf spring works under the frame and loading surface can be flat
-
It controls axle damp
-
Maintenance free
-
Easy repair (quick fix) possibility especially in case of multi leaf springs

DISADVANTAGES
​
-
Heavy system
-
Poor driving comfort (when unloaded)

Linear spring characteristics

Due to production process no proper corrosion protection is possible (or too expensive)
-
Micro cracks, inclusions can remain in leaf spring material after production, therefore breakage can happen
