Description.
Single plate, dry, with
diaphragm
pressure
spring.
This type of clutch differs from the conventional
clutch design because the pressure coil springs
and
all
throwout mechanism components (release
levers, eyebolts. struts. etc.) have been replaced
by a single diaphragm spring.
The new system entails the following advantages:
- the clutch is not apt to slip, even though driven
plate linings are worn extensively
I
thanks to the
special shape and placement of the diaphragm
spring. which keeps the force on pressure plate
unaltered;
- the load on clutch pedal will be practically
the same, whereas in the conventional coil spring
clutch the load increases in proportion with the
pedal travel.
