Abstract
A centrifugal clutch, especially in a hand held work apparatus, such as a cut-off machine (1), a brush cutter or the like, having a rotational axis (20), at least one movably mounted centrifugal weight (25) arranged at the drive end and a clutch drum (16) arranged at the output end. The centrifugal clutch (15) includes a brake device (18) which is released by the centrifugal weight (25) when the centrifugal weight (25) moves radially outward in relation to the rotational axis (20).
Claims18
A centrifugal clutch having a drive end and an output end comprising:
- at least one movably mounted centrifugal weight arranged on said drive end of said centrifugal clutch;
- a clutch drum arranged on said output end of said centrifugal clutch;
- said centrifugal clutch defining a rotational axis and being configured to have an engaged state and a disengaged state;
- a brake device having a released position and an applied position;
- said brake device including at least one brake element;
- said centrifugal weight being configured to hold said brake device in said released position when said centrifugal clutch is in said engaged state;
- and,
- said brake element being held so as to be radially movable.
A centrifugal clutch having a drive end and an output end comprising:
- at least one movably mounted centrifugal weight arranged on said drive end of said centrifugal clutch;
- a clutch drum having a rim and being arranged on said output end of said centrifugal clutch;
- said centrifugal clutch defining a rotational axis and being configured to have an engaged state and a disengaged state;
- a brake device having a released position and an applied position;
- said centrifugal weight holding said brake device in said released position thereof when said centrifugal clutch is in said engaged state thereof;
- said centrifugal weight being at least partially movable in a radial direction with respect to said rotational axis;
- said brake device including at least one brake element;
- and,
- said brake element being mounted in the radial direction between said centrifugal weight and said rim of said clutch drum.
