Our DIN 2093 and DIN 6796 compliant Conical Disc Spring Washers (also known as Belleville washers) offer a compact and highly effective solution for managing axial loads and compensating for settling or thermal expansion in a wide range of automotive applications. Their conical shape allows for predictable and controlled spring force under load. Key Advantages for Your Automotive Applications: High Load Capacity in Small Space: Conical disc spring washers can generate significant spring forces within a small axial space compared to other types of springs. This is crucial in the space-constrained environments common in automotive assemblies, allowing for robust load bearing in compact designs. Precise and Predictable Spring Rate: Designed according to DIN 2093 and DIN 6796 standards, these washers provide a well-defined and predictable load-deflection characteristic. This ensures consistent clamping force and reliable performance in critical automotive joints. Effective Vibration Damping: The inherent design of conical disc spring washers provides excellent vibration damping and shock absorption capabilities. This is vital in reducing noise, preventing loosening of fasteners, and extending the lifespan of automotive components subjected to dynamic loads and vibrations. Compensation for Settling and Thermal Expansion: These washers can effectively compensate for the settling of bolted joints over time and the dimensional changes caused by thermal expansion and contraction in automotive systems, maintaining consistent clamping force and preventing joint failure. Versatile Material Options: Available in various materials including carbon steel, alloy steel, and stainless steel (such as SUS304 and SUS310, known for their corrosion and heat resistance relevant in automotive environments), with different finishes like Zinc Plated, HDG (Hot Dip Galvanized), Black, and GOEMET to suit specific automotive application needs and environmental conditions. Standardized Dimensions and Performance: Compliance with DIN 2093 and DIN 6796 ensures dimensional accuracy and predictable performance characteristics, facilitating ease of integration into existing automotive designs and ensuring interchangeability. Ideal for Automotive Applications Such As: Clamping Force Maintenance in Engine Components: Ensuring consistent clamping force in cylinder head bolts, manifold bolts, and other critical engine fasteners to prevent leaks and maintain structural integrity under thermal cycling and vibration. Vibration Isolation in Suspension Systems: Providing damping and load support in certain suspension components and mounting points to reduce noise and improve ride quality. Brake System Components: Maintaining precise clamping forces in brake assemblies and compensating for thermal expansion in brake discs and calipers. Transmission and Drivetrain Assemblies: Managing axial loads and vibrations in gearboxes, clutches, and differential assemblies. Exhaust System Mounts: Providing flexible and load-bearing connections that can withstand high temperatures and vibrations in exhaust systems. Electrical Connector Retention: Maintaining consistent contact pressure in electrical connectors to ensure reliable signal and power transmission under vibration. Bearing Preloading: Applying a controlled preload to bearings in automotive hubs and other rotating assemblies to reduce noise and extend bearing life.
