After investigating the cause of this difference, it was found that the transmission efficiency of CVT and the effect of the clutch slippage that occurs when the centrifugal clutch
is about to be engaged had not been considered.
All surface-drive motors include a centrifugal clutch
, while motors 9 hp and up feature a dual belt-drive.
However, when the throttle is switched to run and the engine is brought up to the proper rpm, the centrifugal clutch
will engage the pulley and the driven pulley to drive the flexible shaft and operate the eccentric head that generates the compacting vibrations.
Another epicyclic gearset sits between the flywheel, high-speed centrifugal clutch
, and the CVT.
"I made a little rear end, centrifugal clutch
, forward and reverse gears, nothing sophisticated," Kolpin says.
An unexpected wind storm and many years of construction job "left overs" provided a retired union carpenter with the need and necessary materials to design and build a band sawmill for under $100 including blades, v-belts, and a centrifugal clutch
that was needed to complete my first mill.
Other CVTs sometimes fed like a centrifugal clutch
, with revs racing ahead of vehicle response.
And, on this model, pick up from the centrifugal clutch
is pleasingly swift and leaves anything on four wheels doing the usual push clutch, select gear, press accellerator sort of thing while you whizz ahead.
Power is delivered to the rear wheels by a centrifugal clutch
, drivershaft, and quick-change transaxle.
Large gas-powered machines usually have either a manual or centrifugal clutch
. Both make the engine easier to start; a manual gives more control, while the centrifugal one gives some automatic protection against stalling when the machine is overloaded.
The scooters shared common design features: a simple frame with the front wheel steered by handle bars; a 1-cylinder gasoline engine manufactured by established companies such as Briggs & Stratton (I always jokingly referred to those engines as "Briggs and Scrap Iron"), Tecumseh or Clinton; and a centrifugal clutch
. They usually had a twist-grip throttle, a simple cable-activated brake and a seat designed for one person.
