<p>A centrifugal clutch arrangement (2) comprising at least one friction element (4) arranged at, and adapted to rotate together with, a drive shaft (6), a drum-shaped member (8) arranged at, and adapted to rotate together with, a second shaft (10), whereby the friction element (4) is adapted to be displaced between a disengaged condition and an engaged condition. The centrifugal clutch arrangement (2) comprises a torque-limiting means (12) arranged such that the friction element (4), when in its engaged condition, is adapted to be displaced in a radial direction with respect to the drive shaft (6) if the torque between the friction element (4) and the inner surface of the drum-shaped member (8) exceeds a predetermined threshold value of torque, and that the clutch in this case slips. The centrifugal clutch arrangement (2) comprises at least one mass element (14) that is arranged such that it can be displaced and that is adapted to transfer through a transfer arrangement (16) motion from the mass element (14) to the said friction element (4) through the said torque-limiting means (12) such that the said friction element (4) is displaced in the radial direction, depending on the rate of rotation of the drive shaft (6), with respect to the drive shaft (6) for engagement and disengagement of the clutch.</p> |
