Leaf Spring Pressure Block WG9925520366 Sinotruk

Product Introduction

Structure

This leaf spring pressure block is a precision-cast ductile iron component designed for heavy-duty truck leaf spring suspension systems. It features a robust, semi-oval body with eight evenly spaced mounting holes (four in the top row, four in the bottom row) for secure attachment. The surface is embossed with identification markings (including “AD”, “82800”, and “AZ9925520366”) for easy recognition and traceability, and the entire component is finished with a glossy dark gray anti-corrosion coating.

Performance

Constructed from high-grade ductile iron, this pressure block offers exceptional structural rigidity, impact resistance, and fatigue strength, capable of withstanding the extreme loads and stresses encountered in heavy-duty operation. The precision-machined mounting holes ensure accurate alignment and secure attachment, while the semi-oval shape is optimized for uniform load distribution across the leaf spring. The anti-corrosion coating provides superior protection against rust, salt spray, and chemical corrosion, ensuring long-term durability in diverse operating conditions, with a temperature range of -40°C to 120°C.

Core Function

1. Serves as a critical load-bearing and clamping component in leaf spring suspension systems, distributing clamping force evenly across the spring leaves and maintaining their alignment and structural integrity.

2. Transmits and distributes complex loads such as vertical pressure, lateral torque, and longitudinal impact from the leaf spring to the chassis, maintaining the integrity of the suspension system.

3. Maintains precise alignment of the leaf spring leaves, preventing relative displacement under dynamic conditions such as vehicle acceleration, braking, and turning, avoiding abnormal wear of suspension parts.
