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 different 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 rotation speed of the motor at which the clutch unit will transfer power to the wheel (coupling point).
