Friction clutches reduce shock by slipping during the engagement period.
The single-plate or disk clutch,
shown schematically in Figure 13.14 is employed in both automotive and industrial service.
These devices are larger in diameter to give adequate torque capacity. Note that, in an automotive-type disk clutch,
the input disk (fly wheel) rotates with the crankshaft. The hub of the clutch output disk is spline-connected to the transmission shaft.
Clearly, the device is disengaged by depressing the clutch pedal.
The torque that can be transferred depends on the frictional force developed between the disks, coefficient of friction, and the geometry of the clutch.
The axial force typically is quite large and can be applied mechanically (by spring, as in the figure), hydraulically, or electromagnetically.
An advantage of the disk clutch over the drum clutch is the absence of centrifugal effects and efficient heat dissipation surfaces.
