Clutch Disc , Iran
The clutch disc consists of a steel core plate with a thickness of 3 to 5 mm. This core is lined with asbestos-free organic or ceramic friction materials. The dynamic friction coefficient of these materials ranges from 0.35 to 0.45. The standard outer diameter of discs varies from 200 to 300 mm. The disc is mounted on a hub with cushioning spring segments. These segments absorb initial torque shock and dampen vibrations. Coil springs around the hub provide progressive torque transfer. The friction linings operational temperature tolerance typically reaches 350 degrees Celsius.
The disc structure comprises friction linings, a steel plate, damper springs, and the hub. The damper springs are made from hardened carbon steel with a strength of 1500 to 2000 MPa. The clutch disc must transmit 1.2 to 1.5 times the engines maximum torque. The hubs designed angular backlash is between 5 and 10 degrees. This design prevents abrupt force transfer. The permissible wear limit for the friction lining is usually 2 to 3 mm. Modern discs often feature anti-heat coatings on the steel plate. These coatings reduce thermal warping.
