Valeo stock clutch disc and pressure plate for Roniz

• Made in : فرانسه
• Type : استوک
• Brand : والئو VALEO
• Machinery : رونيز

The Valeo stock clutch disc and pressure plate for Roniz are engineered from high-strength alloy steel with advanced heat treatment, ensuring high resistance to mechanical and thermal stresses. The disc diameter ranges from 230 to 240 millimeters, and the plate thickness is approximately 8 to 9.5 millimeters, optimizing uniform torque transfer from the four-cylinder turbocharged engine to the gearbox. The surface friction coefficient is measured between 0.31 and 0.36, providing a balanced combination of smooth pedal operation and extended clutch plate life. Diaphragm springs are calibrated with a compressive force of 850 to 1050 Newtons, delivering stable and smooth performance in both urban and intercity driving conditions.

The Valeo Roniz clutch plate features an organic lining reinforced with metallic fibers and heat-resistant resin, capable of withstanding operating temperatures up to 395 degrees Celsius. Its estimated service life under mixed driving conditions ranges from 65,000 to 90,000 kilometers. Precisely engineered grooves on the friction surface reduce vibrations and prevent uneven wear. The internal damper system can absorb torsional loads of 170 to 200 Newton meters, neutralizing sudden engine shocks and preventing transmission to the gearbox. These features significantly enhance the durability and performance of the Roniz clutch system.
