<p>An easily switchable automatic transmission eccentric shaft includes an input shaft (10) over which a movable centrifugal saddle (20) is fit. An elastic body (13) is arranged between the centrifugal saddle (20) and the input shaft (10). The centrifugal saddle (20) is provided at one side thereof with an openable weight assembly (30, 40), which selectively moves the centrifugal saddle (20) with respect to the input shaft (10). A balance weight (50) is coupled to one side of the weight assembly (30, 40). The balance weight (50) forms a limiting structure (60, 70) that includes two retention members (61, 71) and an elastic element (62, 72) between the retention members (61, 71). The limiting structure (60, 70) helps controlling preciseness of variable transmission, helps increasing available transmission positions, facilitates the weight assembly (30, 40) returning back to home positions, and is suitable for high horsepower applications.</p> |
