Abstract:
1. An automatic transmission eccentric shaft, comprising: an input shaft, which is adapted to receive power input from a prime mover to rotate, the input shaft forming two flat sections on opposite sides; a centrifugal saddle, which is fit over the flat sections and is movable with respect to the input shaft, an elastic body being arranged between the centrifugal saddle and the input shaft; a weight assembly which is arranged at one side of the centrifugal saddle and comprising: a balance weight, which is arranged at one side of the weight assembly and is coupled to the pivot connection portion of the weight assembly characterized in that the weight assembly forms a limiting structure, which comprises two retention members and an elastic element arranged between the retention members; whereby the limiting structure helps controlling preciseness of variable transmission, helps increasing available transmission positions, and facilitates the weight assemblies returning back to home positions.
