Leaf Spring Single Plate WG9731520041-1 Sinotruk

Product Introduction

Structure

This leaf spring single plate is a precision-formed high-strength steel component designed for heavy-duty truck leaf spring suspension systems. It features a long, flat profile with a slight camber, precision-cut edges, and a central mounting hole for installation. The ends are formed into cylindrical spring eyes for pivot connection, and the surface is finished with a dark anti-corrosion coating. Markings such as “16X90” and part numbers are clearly visible for easy identification and traceability.

Performance

Manufactured from premium-grade spring steel (e.g., 60Si2Mn) and subjected to controlled heat treatment, this single plate delivers exceptional tensile strength, fatigue resistance, and consistent spring rate. It is designed to withstand the extreme dynamic loads, impacts, and torsional forces encountered in heavy-duty operation, maintaining its structural integrity in temperatures ranging from -40°C to 120°C. The anti-corrosion coating provides superior protection against rust, salt spray, and chemical exposure, ensuring long-term durability in diverse operating environments.

Core Function

1. Serves as a primary load-bearing element within the leaf spring assembly, contributing to the overall spring rate and load capacity of the suspension system.

2. Works in conjunction with other leaf plates to absorb and dissipate road impacts and vibrations, ensuring a smooth, stable ride.

3. Maintains proper suspension geometry, preventing excessive deflection and ensuring consistent vehicle handling and stability.

4. Enhances vehicle safety and durability by providing a robust, reliable load-bearing solution that can withstand the extreme conditions of heavy-duty operation, reducing the risk of component failure and improving overall reliability.
