2.1 SYSTEM DESCRIPTION, CLUTCH
The clutch is a single dry-plate clutch, which is
hydraulically operated and pneumatically
assisted.
The clutch consists of:
-
flywheel
-
clutch plate
-
clutch release assembly
By clamping the clutch plate between the
flywheel and the clutch release assembly, a
torque can be transferred (by means of friction).
The extent of the torque that must be transferred
by the clutch is determined by the maximum
engine torque multiplied by the safety factor
(usually 1.3).
To clamp the clutch plate, a diaphragm spring is
used in the clutch release assembly.
A diaphragm spring constitutes a simple, strong
and cost-effective construction.
Another advantage of the diaphragm spring is
that the pressure exerted on a new clutch plate
almost equals the pressure exerted on a worn
clutch plate.
The operation of the diaphragm spring (the
coupling and uncoupling of the clutch plate) can
take place in:
-
a push-type clutch
-
a pull-type clutch
