Method for establishing brake disc used in e.g. rail-mounted vehicle, involves tumbling wear-protection layer formed on striking surface of brake disc base portion to enable interconnection of wear-protection layer with base portion

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method for manufacturing brake discs, particularly for rail vehicles, by applying a prefabricated wear-protection layer onto an aluminum brake disc base. The protection layer is attached using a special tumbling process that ensures a strong interconnection between the layer and the base, improving the durability and lifespan of the brake disc.

Use CasesContent extracted from patent full text and abstract with AI.

• Railway vehicles requiring robust and long-lasting brake discs
• Trains, trams, and metro systems where frequent braking causes disc wear
• Automotive or industrial machinery that may benefit from durable, wear-resistant brake discs made with similar technology
• Replacement part production for rail transportation maintenance

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly enhanced wear resistance for brake discs
• Extended operational life of the brake disc, reducing maintenance frequency and costs
• Stronger bond between the protective layer and the base material, minimizing risk of layer separation
• Potential weight reduction by using aluminum bases with durable surface protection
• Improved safety and reliability for vehicles using these brake discs

Patent Abstract

The method involves supplying a brake disc base portion (2) from an aluminum material. A wear-protection layer (3) is prefabricated with dimensions according to striking surfaces of the brake disc base portion. The wear-protection layer is formed on the striking surface of the brake disc base portion. A tumbling tool is led with a hard material contact point across the striking surface of the brake disc base portion. The wear-protection layer is tumbled such that the positive interconnection of the wear-protection layer with the brake disc base portion is enabled. An independent claim is included for device for implementing method for establishing brake disc.
