leaf spring helper springs

Specification: 13/14/15*100
Material: 60Si2Mn
This leaf spring KS400.79.00 has another two OEM numbers: 3893200408 and 30427000 respectively.
The leaf spring KS400.79.00 is composed for two parts: a main spring and an auxiliary spring, wherein the main spring is in the form of 11 leaves, while the auxiliary spring is in the form of 10 leaves.
The first leaf of the main spring is provided with two spring eyes which require two matched bushings, with the dimension of 90xØ36x Ø30.2.
This leaf spring WG9531520164 has a theoretical total weight of 260 kg, wherein the theoretical total weight of the main spring is 162.7 kg, while the theoretical total weight of the auxiliary spring is 94.1 kg.
WG9531520164 is applicable to the vehicle model MERCEDES ARKA.
The leaf spring WG9531520164 has a gradually decreasing curvature, which enables the leaf spring to make contact gradually when compressed, thus providing non-linear stiffness to improve the comfortableness during no-load and full-load. Compared with a traditional linear leaf spring which is too hard during no-load, this model of leaf spring can better adapt to complex road conditions.
Main leaves are thicker and can bear main loads, auxiliary leaves are a little bit thinner, and therefore, both strength and weight reduction can be ensured, avoiding stress concentration.
High-quality shots and advanced shot blasting equipment are used for shot blasting of the leaf spring WG9531520164, such that the anti-fatigue life of the leaf spring is prolonged.
Although the leaf spring WG9531520164 may not have the lowest price, it is lower in overall use cost thanks to its long life and low failure rate.
