Truck Brake Drum Volvo Manufacturer

Truck Brake Drum Volvo

The Truck Brake Drum Volvo series from Xingtai SNT Auto Parts Factory addresses the demanding braking needs of heavy-duty Volvo trucks operating in regional and long-haul applications. Engineered for durability and predictable performance, these drums integrate material science with advanced manufacturing practices.

Material Selection and Casting

For compatibility with Volvo truck specifications, our drums employ a high-grade grey iron alloy with controlled graphite morphology. This composition delivers excellent thermal cycling resistance and wear characteristics. Precision sand-casting techniques, including resin-bonded molds, yield castings with minimal porosity and uniform wall thickness—key factors in preventing stress-induced cracking during heavy braking.

Precision Machining Workflow

Once cast, each brake drum undergoes a multi-stage machining process. Initial rough turning establishes the inner diameter and mounting flange. Subsequent CNC finishing operations achieve a friction surface concentricity within ±0.03 mm and flange flatness under 0.05 mm. Bolt circle accuracy is verified with laser measurement tools, ensuring seamless alignment with wheel studs and hub assemblies.

Quality Control and Testing

Our quality assurance program includes:

• Dynamic balancing: Corrects subtle mass imbalances to eliminate vibration.

• Hardness verification: Rockwell tests confirm the drum surface hardness meets Volvo’s design criteria.

• NDT inspection: Magnetic particle and ultrasonic methods detect any surface or subsurface defects.

Every drum that passes inspection is stamped with a batch number and balance rating for traceability.

Installation and Service Guidelines

The Truck Brake Drum Volvo series is compatible with specified axle configurations, supporting both single- and dual-tire wheel ends. Installation instructions emphasize proper torque sequences for wheel nuts and procedures for measuring drum run-out. During brake service intervals, technicians can resurface the drum up to the minimum diameter specified in our technical manual, extending service life and reducing part-replacement costs.
