<p>A clutch is provided, comprising a clutch weight assembly (10), a main driving assembly (20), a plurality of corotating elements (30), and a base plate (40). The main driving assembly (20) will be rotated when the power source is activated, and the corotating elements (30) are driven synchronously to rotate and then the clutch weight assembly (10) will be driven to rotate synchronously by the corotating elements (30). When the speed of the rotation is high enough and the centrifugal force of clutch weight (13) is strong enough to overcome the inward bending strength of the flexible component (14) of the clutch weight assembly (10), then the clutch weight (13) will fly outward to grab the driven part (60) to proceed the slippery engagement. When the friction resistance between the wear pad (131) of the clutch weight (13) and the driven part (60) is greater than the predetermined transformable strength of the corotating element (30) to make the engagement between the wear pad (131) of the clutch weight (13) and the driven part (60), the power is efficiently transmitted to the driven part (60). Through the enforcement of the engagement between the wear pad (131) of every clutch weight (13) and the driven part (60), an anti-reversal function is provided and the power transmission becomes smooth and stable. Moreover the friction temperature of the wear pad (131) is effectively lowered and the durability of the wear pad (131) becomes much longer.</p> |
