430 series

1. Core material characteristics

• 50CrV4/51CrV4 alloy steel:Using chrome-vanadium alloy spring steel, it has ultra-high tensile strength (≥1250MPa) and excellent wear resistance. Through heat treatment process optimization, it ensures that the spring still maintains stable elastic modulus and anti-relaxation performance under high temperature and high load conditions, extending the service life.

2. Precise specification parameters

• Diameter range: ∮160-430mm (support non-standard customization)
• Thickness range: 1.8-5.8mm (tolerance ±0.05mm)
• Load capacity: 3000-36,000N (smooth linear characteristic curve, precise and controllable separation force)
• Working temperature: -40℃ to +250℃ (adapt to extreme environmental requirements)

3. Full range of model adaptation

• Model coverage: 180/200/225/250/280/300/325/350/380/430 and other full series, meeting the matching needs of mainstream clutch assemblies at home and abroad.
• Customization service: Support customers to provide drawings or parameters to customize special dimensions, loads and surface treatments (such as phosphating, Dacromet anti-corrosion coating).

4. Strict implementation of standards

• QC/T25-2004: Automobile clutch bench test method (to ensure durability and fatigue life meet the standards).
• QC/T27-2004: Technical conditions for automobile dry friction clutch assembly (ensuring the coordinated performance with components such as pressure plate and driven plate).
• Quality inspection process: 100% hardness test (HRC 45-50), metallographic structure analysis, fatigue cycle test (≥500,000 times).

5. Application scenarios and advantages

• Core use: The key elastic component of the automobile clutch plate assembly is responsible for transmitting torque, buffering vibration and realizing clutch separation and engagement.

Performance advantages:

• High load bearing capacity to ensure efficient power transmission of the clutch;
• Excellent anti-creep properties to avoid elastic force attenuation after long-term use;
• Precision stamping technology to ensure the flatness of the diaphragm spring ≤0.1mm;
• Surface anti-rust treatment to adapt to harsh working conditions such as humidity and dust.

6. Supporting and services

• Applicable models: widely used in heavy trucks, buses, construction machinery and passenger car clutch systems.
• Technical support: Provide installation guidance, working condition adaptation analysis and failure mode solutions.

Reason for selection: The clutch system is powered by military-grade materials and precision technology to achieve a smoother shifting experience, lower failure rate and longer maintenance cycle, helping to improve both vehicle performance and user satisfaction!
