Clutch Disc: Maximum Torque Capacity 200-800 Nm

Component Specifications

Definition

The clutch disc is a critical friction component in mechanical clutch-brake systems, consisting of a steel core plate with friction material bonded to both sides. It transmits torque from the driving shaft to the driven shaft when engaged under pressure from the pressure plate, and allows disengagement when pressure is released. The disc includes torsional dampers with springs to absorb vibration and shock loads during engagement.

Working Principle

The clutch disc operates on friction principles. When the clutch is engaged, the pressure plate forces the disc against the flywheel, creating friction that transmits rotational force. When disengaged, the pressure is released, allowing the disc to separate and interrupt power transmission. The torsional damper springs absorb rotational irregularities to ensure smooth engagement.

Materials

Steel core plate (typically SAE 1010-1020), organic or ceramic friction material (asbestos-free compounds containing resins, fibers, and fillers), cushion springs (spring steel), and rivets (steel or copper).
