For FOTON Au truck parts Brake shoe assembly QT300SH1-3502121FW
 

Product Introduction

Working Principle

When the driver steps on the brake pedal, the brake fluid transmits pressure to the brake wheel cylinder through the pipeline, and the piston in the brake wheel cylinder pushes the brake shoe assembly outward. Under the thrust of the piston, the brake shoe assembly opens outward, so that the friction plate is in close contact with the inner wall of the brake drum, generating friction, thereby hindering the rotation of the brake drum and achieving vehicle braking.

Structural composition

The brake shoe assembly QT300SH1-3502121FW usually consists of two parts: the brake shoe and the friction plate. The brake shoe is the skeleton of the entire component, generally made of ductile iron, with high strength and rigidity, and can withstand the impact and friction during braking. The friction plate is fixed on the brake shoe, which is the part that directly contacts the brake drum and generates friction. It is usually made of special friction materials and has good wear resistance, high temperature resistance and friction perforce.
