WONDEE Pickup leaf spring2

A leaf spring is the most widely used elastic element in automobile suspensions.

It is an approximate equal strength steel beam composed of several alloy spring sheets of equal width and unequal length. Its main function is to transmit all forces and moments between wheels and frames, relax impactive load caused by the road surface and realize vehicle guidance, make vehicles normal drive.

Leaf springs are widely applied to suspensions for heavy duty trucks, light duty trucks, pick-ups, cars, skeletal trailers, lowbed trailers, flatbed trailers, oil tank trailers, van trailers, wood transport trailers, gooseneck trailers, agricultrucal vehicles, etc. Classification of Leaf Springs include Conventional leaf springs, parabolic leaf springs, Z type air linkers, TRA leaf springs, trailer leaf springs,light duyt trailer spring, boat trailer springs, pickup leaf springs, semi trailer springs, truck springs, farming/agricultural trailer springs, sprung drawbar, bus springs, bogie/boogie springs, heavy truck springs, etc.

Features


QC management systemImplementing IATF 16949-2016
Services quality management systemImplementing ISO 9001-2015
Product technical standardsImplementing GB/T 19844-2018, GT/T 1222-2007
Warranty12 months since shipping date
Quality testing byStiffness Testing Machine, Arc Height Sorting Machine, and Fatigue Testing Machine, etc.
Raw materialTop 3 steel mills in China
Flat bar cutting & center hole punchingBy fully automatic CNC cutting & punching production line
Center hole positioning tolerance: <±0.2 mm
Cutting length tolerance: <±2 mm
Leaf spring eye rollingUse automatic CNC leaf eye rolling machines, robot assistance, dedicated molds   and toolings to guarantee below features:
1) Perpendicularity tolerance <1% x leaf width
2) Parallelism tolerance< 1% x leaf width
3) Eye diameter tolerance<±0.5 mm
4) Width tolerance of leaf end: -0.5mm ~ 0 mm   
Leaf tapering/parabolic rollingUse automatic CNC parabolic taper rolling machines, robot assistance, dedicated   molds and toolings to guarantee below features:
1) Taper thickness allowance: <±0.25mm
2) Width tolerance of leaf end: -0.5mm~0 mm
Heat treatment lines1) Heating line:
The large-scale automatic CNC temperature control heating furnace not only ensures the heating time but also ensures that the temperature in the furnace reaches the   design value (the temperature difference is within ±5 degrees), ensures that the leaf springs are heated evenly, and avoids excessively high or low temperatures, thereby ensuring the strength of the leaf springs and the service life limit meets the Crequirements.
2) Quenching & camber making line:
Use special CNC quenching equipment, mechanical oil, camber making machines and robot assistance to ensure that the quenching temperature, quenching time and cambers reach the design requirements.
3) Tempering line:

A dedicated CNC tempering production lines are used to ensure that the tempering temperature and the tempering time meet the design requirements. 

So as to ensure the strength and service life of leaf springs.

Camber tolearance (mm)≤±6 (Exceed spring industry standard ±7)
Fatigue life (cycles)>120,000+( Exceed spring industry standard 100,000 cycles)
Hardness41HRC~48HRC
Shot peeningUsing special leaf spring shot blasting machines, the new and used steel shots are   mixed for use. On the one hand, the new steel shots increase the deformation of the springs. On the other hand, the used steel shots have no edges and corners to avoid microcracks on the surface of the springs, thereby increasing the fatigue life.   
PaintingNormal painting and E-coating are available.
*E-coating finish line: paint film is uniform and plump, with strong adhesion and high anti-corrosion performance, to avoid dripping, flow marks, stagnation marks and other problems.
* Salt spray test >100 hours
Marks/stickers

* Clients' logo are supported 

* Design marks or stickers for clients, free of charge
