The brake shoe assembly (Part No.: 860545409) is manufactured through precision processes to ensure reliability and compliance:
Material Preparation: High-friction composite material (asbestos-free, meeting 26865) and stamped steel backing plates are pre-cut to specifications.
Molding & Bonding:
Friction linings are molded under 150-200°C and high pressure (10-15 MPa) for optimal density.
Linings are bonded to steel plates using heat-resistant epoxy adhesive, cured at 80-100°C for 2-4 hours.
Machining: CNC milling ensures precise dimensions (±0.1 mm tolerance) for bolt holes and contact surfaces.
Heat Treatment: Backing plates undergo quenching and tempering (heated to 850°C, oil-quenched, tempered at 400°C) to achieve 40-45 HRC hardness.
Assembly: Springs, pins, and adjusters are installed with torque-controlled tools (15-20 Nm).
Testing: Each assembly undergoes friction coefficient tests, wear resistance trials, and 10,000-cycle durability simulations.
Strict quality checks ensure alignment with performance criteria.
