1.3 Clutch General Clutch composition A ingle disc clutch kit is composed by a clutch cover, a clutch disc and a release bearing. Function The clutch is a very important part in the driveline, it is located between the engine and the gearbox. The functions of the clutch are: ●● Transmit 100% of the engine torque to the gearbox ●● Interrupt the transmission of engine torque quickly and completely ●● Damp out the vibrations coming from the engine (acyclisms) ●● Allow modulation of the transmitted torque by slipping (move off, gear shifting, maneuvers) ●● Protect the drivetrain

Clutch torque capacity The clutch torque capacity means the amount of torque that can be transmitted by the clutch when it is fully engaged. It depends on different parameters: Tc = P x F x N x R Tc = Torque capacity (Nm)  P = Cover assembly pressure load (N)

 F = Friction coefficient of the facing material  N = Number of facings (2 for single clutch disc, 4 for twin-disc clutch)  R = Clutch disc radius Safety coefficient

To ensure a full torque transmission in any conditions, a safety coefficient is applied to the engine torque:

Clutch torque = engine torque × K (safety coefficient)

The safety coefficient (K) is 1,15.
