Friction Brake Body, in Particular Disc Brake, and Manufacturing Method Therefor

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

This patent describes a friction brake body, particularly a disc brake for motor vehicles, made at least partially using forming techniques. The brake comprises friction rings with braking surfaces, a cooling section between the rings, and a mounting section. Key innovations include the use of high-strength, corrosion-resistant steel alloys (such as stainless or chromium-iron alloy) and advanced manufacturing processes (forming, deep drawing, and possibly powder metallurgy) to enhance durability, reduce weight, and improve corrosion resistance, especially for vehicles with electric drive systems that use mechanical friction brakes less frequently.

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

• Disc brakes for electric and hybrid vehicles, where mechanical braking is less frequently required due to regenerative braking systems
• Automotive disc brake systems that need high corrosion and wear resistance for extended lifespan in challenging environments
• Disc brakes in commercial vehicles or heavy-duty applications requiring high mechanical strength and minimal maintenance
• Manufacturing of brake components using cost-effective forming or powder metallurgy methods for high-volume or small-batch production
• Replacement parts for vehicles seeking performance and durability upgrades in the braking system

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly increased corrosion resistance compared to traditional cast iron brake discs, leading to longer lifespan, particularly in low-usage scenarios
• Ability to use high-strength steels and stainless steels, allowing for lighter and more durable brake designs
• Improved suitability for electric vehicles, where reduced use of mechanical brakes can otherwise lead to premature corrosion of cast iron discs
• Manufacturing flexibility: the process supports both large-scale and small-scale production in a cost-effective way using existing forming and powder metallurgy techniques
• Lower emissions of fine particles due to harder brake pad compatibility, contributing to reduced environmental impact
• Material and design choices enable better recycling and maintenance, as well as possible reductions in overall vehicle weight
