Figure 4.2: 3D-model of the ISCC, the
colored parts green, red and blue
depicts successive:
-the plunger,
-the cone friction ring and
-the clutch body
The grey part is the drum, the holes you
can see are the inlet actuation holes and
some cooling holes

The copper colored part is the carrier
flange. These holes you can see in this
part, are the connections for the
carrier of the planetary gear.

The force in axial direction is depended of two variables;
the pressure of the oil p in bar
the dimensions of the pressure surface A in mm²
The following equation is formed:
FA
p
=⋅

Due to the power loss by the vespels, the pressure of the actuation oil must be kept as low as possible.
Yet, the force to keep the clutch closed, is still required. With the use of centrifugal force, the pressure
of the actuation oil is minimized. This results in a design which requires centrifugal force. This can be
achieved if the plunger surface (oil chamber) is constructed with a big outer radius. The plunger
surface is designed as big as possible. All available space for the actuation chamber is been used.
