There is a design for a toy 'automatic clutch' in Meccano Magazine of June 1934. [4] Armstrong Siddeley cars featured automatic (centrifugal) clutches beginning in 1936. [5] Thomas Fogarty, who is also credited with inventing the balloon catheter, is credited with inventing a centrifugal clutch for small motor applications in the 1940s. [6]
Another example of a rotating device in which a reactive centrifugal force can be identified used to describe the system behavior is the centrifugal clutch. A centrifugal clutch is used in small engine-powered devices such as chain saws, go-karts and model helicopters. It allows the engine to start and idle without driving the device, but ...
A centrifugal clutch is used in small engine-powered devices such as chain saws, go-karts and model helicopters. It allows the engine to start and idle without driving the device but automatically and smoothly engages the drive as the engine speed rises.
The clutch's input shaft is typically attached to a motor, while the clutch's output shaft is connected to the mechanism that does the work. In a motor vehicle, the clutch acts as a mechanical linkage between the engine and transmission. By disengaging the clutch, the engine speed (RPM) is no longer determined by the speed of the driven wheels.
At idle speed, the engine is disconnected from the gearbox input shaft, allowing both it and the bike to freewheel, unlike with torque converter automatics, there is no idle creep with a properly adjusted centrifugal clutch. As the engine speed rises, counterweights within the clutch assembly gradually pivot further outwards until they start to ...
The centrifugal clutch was engaged above a certain engine speed by centrifugal force acting on spinning weights inside the clutch, similar to a centrifugal governor. The servo clutch used an electric switch that supplied manifold vacuum via an actuator valve to a reservoir that disengaged the clutch. The clutch is disengaged automatically ...
