PROGRESSIVE ENGAGEMENT CLUTCH

摘要

The progressive clutch includes a centrifugal clutch (10) attached to a drive shaft and inserted into a clutch housing assembly (16) to engage with clutch material (28) during low rpm operation. As the rpm of the input drive shaft (2) increases, the centrifugal force on pellets (32) overcomes the force of compression springs (34), and extension springs (40) pull a pin engagement assembly (30) towards the clutch housing assembly (16) thus engaging pins (38) into elongated holes (42) to provide positive drive from the drive shaft (2) to the driven shaft (21).
