Multiple Disc Clutch

Multiple plates on input and output shafts are brought together to transmit torque. The multiple plates increases the frictional area.

Where

M_r = Transmitted torque [Nm]
μ = Coefficient of friction
F = Force [N]
D = Outer diameter of friction surface [m]
d = Inner diameter of friction surface [m]
N = Number of friction contact pairs
