Centrifugal Clutches and Brakes
How they work....
|
The sprung tensioned flyweights rotate faster until they start to engage with the housing. This speed controlled engagement means they can function as an automatic clutch or brake to control descent rate.

Centrifugal Clutches
Combidrive Ltd. is the UK distributor for the German company Robert Scheuffele (Trademark 'SUCO')
Centrifugal clutches from the SUCO range are often to be found in the following machinery.
Combidrive can offer complete SUCO clutches or spare parts and even if the SUCO may have been fitted as original equipment, there is a good possibility that we can offer an interchangeable unit from stock.

CENTRIFUGAL CLUTCH/ BRAKE -
PRINCIPLE OF OPERATION
Friction lined flyweights are held in position by springs which can be changed to adjust the speed at which the clutch/brake begins to engage.
As the hub accelerates, centrifugal force acting on the flyweights, overcomes the spring tension, allowing the friction lined flyweights to bear on the housing and so impart drive (when acting as a clutch) or braking effect (when acting as a brake)
Watch the housing accelerate as the clutch engages. IT'S ALL GRIPPING STUFF!!
