Springs for FLY / DELTA clutch
and ORIGINAL clutch
Pre-hardened carbon steel springs, with high
yield strength, that are protected by a high
heat-resistant painting in various colours.
The diff erent colouring shows the load of
each spring series.
Operation
Depending on its own geometrical and
technological features, each spring has a
well defined value of load-elongation ratio
(k).
Therefore, elongation values being equal, a
spring that requires a higher strength, will
have a higher load-elongation ratio (k).
Inside a clutch unit , springs specifically aim
at fixing the coupling point of clutch masses
on the clutch unit drum-cap, thus opposing
the clutch-mass expansion movement
produced by the centrifugal force.
So, the higher the load-elongation ratio
(k) of the clutch spring, the higher the
